Synthectic to regular motor oil!!??

[Fai]

How bad is it for the MSP if I change back from synthectic to regular engine oil? or can i do that... cause I kinda tight on money and synthectic is kinda expensive.. does synthectic really worth the price?
just wanna know thz...

(drive)

[toucci]

bad idea man! (wow)

[MSP #167]

yea its not good, once you go synthetic you shouldn't go back.

[bored132]

thats all a myth about switching back and fourth:

You can switch back but the turbo likes the syn. over regular oil

i believe you should jest keep the synthetic. it lasts a hell of a lot longer than the dino-oil and takes longer to break down. you then can change it on longer intervals and make the cost even out over the long run. You probably pay 2.5-3 times more for synthetic but it can last about 2-3 times longer than dino-oil. i don't think it is worth it if you use synthetic and change every 3K. i use synthetic and change between 5-7K. Mobile 1 says their stuff can can go 20K with a filter change at 10k. i believe that is a little to long.....i am sure I can go 10K between changes and that would be fine. 7K is a goodand cost effiecent.....

my $.02!

[ONRAILS]

wow... I guess I'm wasting money, I change my royal purple every 3k. (drive)

I would stick with syn on a turbo car... less coking

[Protege52003]

what does royal purple recommend for changing intervals. hell if they say 3k, which i doubt they do, that is fine......i bet they say much longer than 3k though.

i would feel like i was wasting my money changing my syn oil every 3k. i feel a little better doing it every 7k'ish. maybe i will hold off a little longer (8k or half a year)? I do a lot of driving though.....

another topic like this is when people use prem gas in a car where regular is fine. they don't understand that there will be no difference in the way the car runs or performs from recommended octane. sometimes an older engine might require higher octane to minimize pinging and other noises?

well, have to get back to work......

Good luck with regular on a FI application.

[evolv]

well this is right off the Mobile site

so when you change is up to you. if u have warranty left, maybe changing at intervals is best

You can go all the way to the maximum mileage or time frame shown in your owner's manual for oil changes when using Mobil 1 with SuperSyn™. This allows the reserve protection capabilities of Mobil 1 with SuperSyn™ to cover the unusual or unexpected driving conditions that we all experience from time to time.

Oil change intervals can be as short as 3,000 miles or as long as 15,000 miles on some new cars. Mobil 1 with SuperSyn™'s high-performance reserves give you the confidence to go the full mileage or time frame recommended by the vehicle manufacturer. Mobil 1 with SuperSyn™ is especially suitable for the latest vehicles with extended drain intervals or vehicles with oil monitoring systems that vary oil drain intervals.

did i say that i had an FI car? i drove a saab 900 turbo for many years and could run 87-93 octane. liked the higher better when pushed hard, but I could use 89 with no problem.

[Puckpimp71]

My dad's old 9-5 2.3t had no problem running on regular. His 2003 Cobra SVT, however needed premium and now he's got a 2001 9-5 Aero (same 2.3t but basically higher boost and better ECU) that needs premium. FI or N/A doesn't really matter. It all depends on how your engine's made to take it. With oil, however, since superchargers and turbos spin so fast, and get very hot, I think full synthetic is always a better choice.

[Protege52003]

i knew this was in the MSP section. i just made the original symthetic oil statment and comparing it to the octane example in saving money sense. my fiance drives a jetta with the 1.8 T and it runs fine with with regular. VW says run at least 87 in the car but higher octane might perform better.

my father drives the 626 with the 2.5L V6 and it can run on 87-93. it runs fine on regular but performs much better with the higher octane.

what does the owners manual say to use for the MSP?

sorry to cause any tension here...in the MSP section.

MSP owners manual say 91 octane at least.

yep its a myth. Its no big deal...

[Protege52003]

so high test all the way......i thought that it might say it was okay to run lower octane like other turbo'd cars that I know of. thanks.....

[girth]

yep its a myth. Its no big deal...
Agreed.

[yashooa]

I change my Mobil 1 every 6-8000 miles. So far after 52,000 miles at 12PSI my car has held up fine 4 quarts go in and 4 quarts come out every time.
The cost is offset somewhat by the longer intervals.

[Mr. Win]

acutally on a turbo'd car you should change the oil every 3k... esp at that boost. Do what works for you.

this is what i like to see......

yashooa, how does your oil look when you change it? probably similar looking to when you first put it in?

[Quik89Si]

First change, I got regular at 3k. Then I got Mobil1 Synth at 6k with a crappy filter, so I changed it again at 9k with a K&N filter and more Mobil1. This next time, I don't think I'll change it until 11 or 12k with more Mobil1 and another K&N.

[Swerny]

I change my Syn every 5000 Kilometres, which is 3000 miles.
Cheap insurance.

[NeverSober]

I run syn. but one morning before school, all my oil drained...dunno why but it did. Regaurdless I had like $5 on me and I had to switch back to reg for the time. Its only been about 500-600 miles. I am changing my oil back soon, I have the syn in my trunk right now, just lazy.

Chris

[Pretzellogic]

I currently have Mobil One in my car. I change it every 5000 miles. Easy enough to remember.

Not sure if I should cut it down to three grand when my turbo goes in next weekend, though.

[bored132]

i change mine every 2,000 miles, more insurance never hurts :)

[unwound]

i think mazda recommends 5000-mile oil change intervals which is what i do. mobil 1 and just the regular, small mazda oil filter.

i wouldn't think changing from syn to dino would cause you to notice any differences.

as everyone else has already stated, syn is always better for FI.

[MiataRacing]

I go 5000 miles on Mobil 1 and 3000 miles on dino oil. I figure it pretty cost effective to use Mobil 1 because you change your oil and filter less frequently. I just switched from Mobil 1 to dino because I got some free oil from Valvoline Racing. Can't beat free...

The 3000 mile oil change on a NA car is a myth perpetuated by the oil companies and retail/lube shops. Most cars will go 5-7k before its get to be a problem. We used to save money on a 10,000 car fleet by changing oil every 7k and we saw no noticeable increase in loss of engines. Of course, that was a lot of Ford Taurus's and not a MSP.

Turbos run hotter and breakdown the oil quicker so it's probably good insurance to change it more frequently than a NA car.

Was your car jacked up and a whole bunch of stuff missing too? Crap! (wow)

I just changed to Torco full-syn after running a syn blend for while. Noticed a smoother running engine and less vibration throughout the car. With AWR mounts, that was a really noticable difference.

All full-syns can go 7k before change? Or is that a mobil1 thing?

[laracroft]

I use Royal Purple Street... no problems with it. Not a huge noticable difference in driving, but I think it works pretty well.
