Oil (Synthetic?)

[fkmp5]

What kind of oil do you use?

[fkmp5]

wow.. i thought more people would vote.. or reply. something! :)

[servoeyes]

Just changed the oil in Aeris over to Royal Purple....felt nice, but it may have just been the weather...we'll see tomorrow! Sorry I don't own a P5, but similar engines...and the topic is oil...we all gotta use it! :D

There you have it folks!!!

[Sir Nuke]

well there ya go....the very reason why no one had answered...because they already had....in other threads...many times.

[fkmp5]

yes those threads are fine and dandy (and i did a search on "oil" before i made my original post) but none of them are an actual survey to see what kind of oil people are using.. i'm more interested in how many people are using synthetic.. those threads lead me to other conversations like, "have you ever heard of royal purple" .. and one of them leads to a discussion about tranny oil, etc..

i'm just trying to get an idea of how many people use synthetic and if they think it's better or at least safe.

I know a lot of you don't wanna hear this or don't care, but it's not worth it. 2.0 liter, 130 hp, economy engine has no need for full synthetic. Money down the drain......(unless you seriously think it's a high performance engine)

I have no illusions that my P5's engine is a high performance engine. Twenty years ago, having a 2L engine that makes 130HP would have been considered high performance, but not by today's standards. However, good motor oil is good motor oil and ANY engine can benefit from superior lubrication and oil longevity. It won't give any noticeable HP gains, but an engine will certainly last longer if it's lubricated better. That's a no-brainer.

[Protege5Lava]

just did 2nd oil change using Mobile 1 10w30 yesterday at 24,000 miles, maybe the first time cleaned out the crap really good or something :D , cuz i noticed less knocking sound when warming up my car this morning....i'm willing to spend a little more since u end up saving a lot more in the long run.

[WaatDaHell]

Well, a few years down the road, just think about how much you've spent on motor oil, and ask yourself, "how many more years am I gonna drive this car?" Then maybe you'll think "last so much longer for what?"

[WaatDaHell]

Oh, if that's such a no brainer, go ahead and use premium gasoline and wax it every week while you're at it. Since it's good for your car, why not right? You'll feel so gooooood inside!!!

Our cars don't require high-octane fuel and I don't use it. :o Comparing the use of high-octane fuel and synthetic oil doesn't make sense. If your engine is high-compression or forced induction then premium fuel may be required. On the other hand, motor oil that has superior lubrication (& longevity) properties will be beneficial in ANY engine. BTW, I typically keep my cars for about 10 years. Longevity is important to me.

Hey Jack, ever heard of a 1983 Honda Accord going 350,000 miles without using Synthetic? Ever heard of a 1980 Toyota truck going 600,000 miles with regular oil? If not, I've driven both and yes they're still running. The way engines are built nowadays, you think we need better oil than what those cars needed? Oh please.........and you don't understand the logic of comparing this to premium fuel? I give up.

[johnjay5]

Boo flamewars hehehe j/k i use Mobil 1 Full Sny-tec 10w30

[Jack Daniels]

I guess it boils down to how much return you get for the extra $$$ synthetic costs. If I had to pay someone to change my oil, I doubt I'd be using synthetic. Too expensive. I buy Mobil1 at Wally World for about $17/5qt jug + $3 filter, so a $20 oil change isn't that bad. :)

Now about comparing synthetic oil to high-octane fuel, here's another way to look at it. If high octane-fuel gave you better gas mileage (which it doesn't) even though your car didn't require it, you might be inclined to use it if the price wasn't much more than regular fuel.

Synthetic motor oil is better and will last much longer than dino oil. That's a fact. So, if I can use synthetic for maybe $10 additional per oil change, doesn't it make sense to do so?

[MadBiker]

I'm switching to synthetic next oil change for my mp5, and then also for my rebuilt engine on my '98 626 after it's broken in a bit more. Can't wait!

Used synthetic oil before in my V6 Diamante and it made the engine verrrry quiet and smooth. The change intervals are also longer too so the extra price you pay is negated.

mmmm, love the stuff..

[Red Baron]

Mobil 1 5W30

Engine sounds better, and since temps go down to around -40°C in the winter here in the North (and up to +32°C in the summer), synthetic oil DOES make a difference. Yes it is WAY more expensive, but if you keep the car for as long as I do, I think the extra money IS worth it.

My 1990 Civic Si had only 275000km on it after 10 years and I had used all kinds of additives (Teflon types), but the engine had to be rebuilt so I sold the car...I figure that THAT was a waste of money. Next car was a 2000 Civic EX (4 doors) and only synthetic has gone in the engine and you should hear the difference (now at 94000km, my wife has it now and she has a lead foot...). The Civic EX can still give 40mpg (43 on the highway), my P5 just now is at 38.5mpg (that's 32mpg US).

Oh and BTW, REAL pure Maple syrup from Quebec (so is our beer)is lightyears better than junk like Aunt Jemima...:D

[unwrittenLaw]

^
Aunt Jemima is gonna come and woop yo ass!

[p5mica]

Waatdahell, You never figured in the service interval into your calculation. Figure synthetic will last AT LEAST 3 times as longer than dino oil while still giving superior lubrication may be enough to sway people toward syn. And it only costs about twice as much as regular oil.

[Brian MP5T]

Mobil 1 5W30 Synthetic.

On Day One with 32Km on the Car I changed to Synthetic. The oil has no impurities and unless your car has many miles on it on regular oil, I urge everyone to spend the extra money and make a switch. If you drive your car in the winter, synthetic oil is alot less likely to turn to "Sticky Goo" in your oilpan. Enjoy

[MadBiker]

Finally switched! at 19,604 miles put in Kendall GT-1 Full Synthetic. That's the only brand that the Firestone Svc Ctrs (yeah, I'm a pay-others-to-do-it-for-me guy) carries (but including tire rotation and taxes etc. it was about $43 total). Very smooth!! WootWoot!

Quickie question for any of you still on this thread:
The Firestone dudes said that the oil's good for 10,000 miles, but do I need to worry about the oil filter getting clogged by that time?

I use valvoline 10w30, and change every 3k. Just coming off a four year relationship with a Volvo 850 that required premium unleaded and synthetic motor oil. I talked with a Volvo tech who said he would change between 3-4k no matter what type of oil you use. Too many opinions maybe

[anarchistchiken]

I use Castrol Syntec in the P5, but that might change to Royal Purple next time. Depends on how much the stufff costs around here. Maybe even Mobil 1. That's what we put in the Land Cruiser.

But I have a question. What exactly is the difference between 5w30, 10w30, 5w40, 0w30, and the rest? I know the first number is for the ambient outside temperatures you're driving in, but I'm at a total loss for what the second number desgnates. Anybody?

[Turbo Matty P]

Miller, I run the Royal Purple 5W30 in my msp and p5...it's good stuff...do the same and don't question me.

p.s. the numbers represent the viscosity of the oil above freezing and below freezing.

[Eitel]

Mobil1 10w30. And today it's getting an oil change. ;)

[leungwingkei]

Good ol fashioned Castrol GTX, the FS-DE is not high performance enough to warrant the use of synthetics IMO.

[Micah]

I use full synthetic and change every 3.

I love the retards that use full synthetic and then wait longer than 5k to change the oil. The point of using a synthetic oil is that it doesn't break down as quickly as "dino" oil. When you run the oil that much longer, you are completely negating the point of using synthetic in the first place.

Some people are just too damned cheap. Get a job or something. The oil is a very important part of the car, why would someone cheap out on that?

[RyanJayG]

the thing is is that the synthetic doesnt REALLY break down at all, it just gets dirty, and the particles are smaller than the oil filter can remove, so either change it after 5K miles or get a .5 micron filter to clean your oil in a seperate loop from the stock oilcleaning system. if you do this you can run full synthetic nearly forever (overstatement, but making a point)

the drawback is that this would probaly cost more to do than just to do regular 5K mile oilchanges. besides is $25 too much for 4 quarts and a filter? I think not... learn to change your own oil people... save a fortune

premium fuel = costly! 10cents more per liter, plus the ECU isnt programmed for it, and our cars arent even high compression, so whats the point?


oil change, 20 bucks for synetic, guessing about 5-10 for regular.
oil seems more affordable man. The engine wear over time is less = u can keep more power.

Im going synetic once i get a new car


btw Im gonna have to ask a really NEWBIE question... ppl are saying
moblie 5W30
wats the does the 5 and 30 mean?

Yep, Walmart sells the 5 gallon jobby of Mobil 1 for like less than $17.

Of course now that I work 7 days a week, I just pay the Jiffy Lube people and get my free car wash. I'm thinking of trying Sears Auto next time though, just need an excuse to use my Sears card.

somethign W something... huh?lol



On every bottle of motor oil there is a seal that gives you three pieces of information:

The API service rating
The viscosity grade
"Energy Conserving" indicator (it either is or it isn't)
The API service rating is a two-letter rating that tells you the type of engine the oil is meant for (gasoline (http://auto.howstuffworks.com/engine.htm) or diesel (http://auto.howstuffworks.com/diesel.htm)) and the quality level. See this page (http://auto.howstuffworks.com/framed.htm?parent=question164.htm&url=http://www.quakerstate.com/products_services/knowledge/oil_5.htm) for a description of the different ratings.


The viscosity grade (for example, 5W-30) tells you the oil's thickness, or viscosity. A thin oil has a lower number and flows more easily, while thick oils have a higher number and are more resistant to flow. Water has a very low viscosity -- it is thin and flows easily. Honey has a very high viscosity -- it is thick and gooey.

The standard unit used to measure viscosity is the centistoke (cSt). According to this page (http://auto.howstuffworks.com/framed.htm?parent=question164.htm&url=http://www.escape.ca/~dbrad/glossary.htm):
Viscosity is ordinarily expressed in terms of the time required for a standard quantity of the fluid at a certain temperature to flow through a standard orifice. The higher the value, the more viscous the fluid. Since viscosity varies inversely with temperature, its value is meaningless unless accompanied by the temperature at which it is determined. With petroleum oils, viscosity is now commonly reported in centistokes (cSt), measured at either 40°C or 100 °C (ASTM Method D445 - Kinematic Viscosity).
The centistoke rating is converted into the SAE weight designation using a chart like the one shown on this page (http://www.superiorlubricants.com/classtable.html).


Multi-weight oils (such as 10W-30) are a new invention made possible by adding polymers to oil. The polymers allow the oil to have different weights at different temperatures. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. This page (http://www.repairfaq.org/filipg/AUTO/F_oil_facts.html) offers the following very interesting description of how the polymers work:
At cold temperatures, the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up, the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C, the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot.

For good oil info, check out www.bobistheoilguy.com (http://www.bobistheoilguy.com). Fantastic amount of real world test results, and Moderated by real live oil experts. With that said, I use Mobil Delvac 5W-40 synthetic. It has the proper gas engine ratings, a fantastic base oil and the much better diesel rated additive package. Yes, I know that our EPA ninnies specify 5 or 10w-30 for the miniscule mileage advantage (maybe 0.6 to 1.6%; not measurable in the real world) but this car is MINE. I live where it gets past 90 degrees f (look closely at the owner's manual picture chart-seems to not really address HIGH temps past the end of the pointer bar) and I may want to keep it forever. Plus, OTHER COUNTRIES AROUND THE WORLD get Xw-40 or Xw-50 oils specified on the very same motors that the USA gets. Screw the EPA; I want the added protection.

[davco]

I'm switching over to Mobil 1 5W-30 today. I used it in my old car (about 4 years ago) and it did fine. But it seems to be cheaper to buy now than it was then. $4.07 compared to $5 (what about inflation). Why?

[PhatTrax]

$4... where!? It's like $5 here, but the only place i know that carries it is wal-mart and autozone and they're the same price.

well i use Mobil1 5W-30 in the summer and 10W-30 in the winter... because where i live in the summer it can peak over 100 degrees and in the winter, it can occasionally drop below 0 degrees but every winter it gets below freezing. I do put 93 octane into my car also. If im just going to be driving a long distance i will put some medium grade or lower grade in it, but for just zipping around town i put the 93 in there. i usually only put 5 dollars at a time of 93 octane, just because i dont want to fill up on it and then drive 2 hours. I also use K&N gold oil filters. I guess the reason i use them is because they come off with the use of a socket. soo easy to do. I know I spend tons of money on "stupid stuff", but i take care of my cars.

Your point of who knows how long im going to drive this car is rediculous. If thats true then just ride around on bald ass tires, leave any body kit or repairs you get unpainted, don't bother washing it, hell don't even change the oil, because really, who knows how long you are going to have that car.
im a firm believer in taking care of what you have. if you get a new car, old car, or even a new house, then you should take care of it. don't just rag your shit out. We are car enthusists, not your every day soccer moms that just beat the shit out of their cars and don't care whether or not it lasts another year, so yes we are going to take care of our cars even if they are the fastest damn things in the world.

Most engine wear from what I understand is at start up. 0W affects the cold portion, 30 is for the hotter temp. Once running at temp the 0W-30 is the same as the 5W-30.

It gets cold in the winter here and I don't use a block heater and the car is outside. I want that oil flowing quickly.

Some people are just too damned cheap. Get a job or something. The oil is a very important part of the car, why would someone cheap out on that?
There are a lot of myths out there about car maintenance and this is definitely one of them. Oil and filter should be changed at the interval recommended by the manufacturer. That's every 5k or 7.5k miles for the Protege5 depending on what kind of driving you do, and that is assuming you use dino oil. Even Mobil 1 recommends that you go the maximum amount of mileage allowed according to your owner's manual. If they wanted to sell more oil then they could easily recommend that you change it more frequently, but they don't, because they know it's bad business to propagate false information. My point is that if you're being conservative, you should change your oil according to the intervals in the owner's manual, which for the Protege5 can be up to every 7.5k miles. It obviously isn't going to hurt anything other than your pocketbook and your free time by changing it more often than that, and I wholeheartedly suggest doing so if it gives you greater peace of mind. But suggesting that it should be done more frequently than the owner's manual calls for just spreads the myth.

You can go off and call people retards for going more than 5k miles between oil changes, but I would say the same thing about someone like you who trusts Jiffy Lube to change their oil and filter for them. And calling them cheap because of a longer interval???? That would be like if I claimed everyone who paid to have their oil changed was too damn stupid to change it themselves.

very interesting article. thanks for posting that. so i'm no longer worried about taking the oil out to 5k-75.k, but what about the filter? also, while i'm at, what filter do you guys use? i've been stickin' with the mazda one just because most on mx6.com (my old car) used it and said that it worked the best, however i feel with how expensive it is, there's got to be something better out there. anyone want to weigh in on that? i heard there's a k&n deeper oil filter, but didn't know anything other then that. anyone know the filter grain size on any of the filters? just things popping into my head on this general topic. thanks for the info guys, talk to you later

The Napa Gold filter in that test went for 12k miles. I wouldn't want to get anywhere near that mileage in my own cars, but that's because I have more peace of mind by following the maintenance schedule. I religiously change with Mobil 1 synthetic and an OEM filter every 5k miles, but I personally wouldn't be concerned in any way if I had to let it go to 7.5k.

I always use Mazda filters and I don't consider them to be expensive at $5 each. How much money are you going to save each year by going with a cheaper filter? Less than $10, right? I don't see why anyone would try to find something cheaper when your total savings would so insignificant.

i think maybe he meant inexpensive... so there's gotta be something better...

but the best stuff doesn't always cost the most, just remember that too.

[lavajumper]

well i just meant that i want to go with a good filter. if the napa gold is it, and it's 8, no problem. or if the mazda oem is best, and it's 8, don't matter to me. i just want to get the best one really, without spending like 20 bucks a pop. that's all i was looking for really. thanks

You might find this article interesting, though the Mazda filter featured is not the newer one they've started using. The new one reportedly has better filtration.

So after going thru this thread i'm guessing it's too late to switch @ ~35000 miles?

Thanks

You can switch. You'll notice it's smoother and has a better temp range so easier starting in cold weather also.
