Thanks for your input but no need to talk trash.
My apologies if you got the wrong idea, I've not intentions to insult you.
And speaking of foolish all DI engines (including Mazdas) have carbon buildup except for DI engines with port injection/meth injection to clean the valves.
Can you show me a thread with photos of dirty skyactiv valves?
When I mentioned driving like I stole it, I meant driving in sport mode or paddle shifter revving out the engine (once the car is warmed up) on the highway. If you baby the car with regular gas, and never go above 3k rpm don’t be surprised at 30.000-60,000 miles when you need walnut blasting to clean the intake valves due to misfires).
Occasionally, threading the needle to 5000rpm or so (lets say 4x per month, in second or third gear), could help clean out the fuel injectors and increase temperatures enough to clean some deposits out the engine and exhaust. Yes, always driving below half throttle will cause some deposits, no, constantly revving out your engine is not "better!"
In New Jersey, if you drive the turnpike/parkway (south Jersey mainly at night), it’s like the Audubon. No body drives the 65 mph speed limit. Most drive 80+ and on the down hill most are doing 100+.
I am not concerned with the impatience, needs, or intentions of the people behind me trying to pass. I am focusing on how my drivetrain wishes to be driven and follow the transmissions desired shift strategy accordingly. My priority is #1. Safety of everyone involved, including potential animals near or on the road, and #2 Efficiency. That does not mean I don't enjoy driving spirited. I like to push quite hard around the bends and my car is on a custom 91 octane tune. I will get to that.
Yes, on the highway when everyone is driving significantly faster than you, unfortunately, it makes sense to speed up a little. By no means can we dismiss this as no big deal. It is very dangerous!
In regards to letting the car idle, I meant when driving it hard/boosting in the canyons and then immediately turn off the car. I prefer to let the car idle for 30 seconds so that the oil does not cake/sludge in the turbo alternatively just drive slowly for last couple miles.
Clean oil will not cake or sludge anywhere. Idling for a minute immediately after going full throttle is a sound practice. You do not need to have the heat on in the cabin while doing this. The radiator fan is already taking care of excess heat. Just drive normally for 5 minutes before you shut the engine off.
And you’re right about my license is a privilege and not a right.
This is not simply about a drivers license. This is also about the health and safety of the environment, as well humans and animals alike. This also includes the responsible usage of our vehicles and the resources required to both manufacture and process them. If you do not choose to acknowledge these simple facts, I suggest that you refrain from driving. It would do you and those around you much good.
I rarely exceed 100 for more then a few minutes But I do not do those kind of speeds on local roads only on highways
Sometimes, I like to go fast. I do not do it often. When I do, I will sometimes push my drivetrain quite hard to get there. I rarely ever do so for a prolonged duration.
following people who are going much much faster than I am (follow the rabbit rule).
Unless there is a real danger of being clipped by drivers trying to pass you, just drive normally!
I do not weave in and out of traffic
I am currently 25. When I was a teenager, I was a very dangerous and aggressive driver. after the age of 21, I became much more conservative and patient. It genuinely scares and concerns me to see individuals significantly older than 25 behaving with zero patience or concern for safety and efficiency when they drive.
If you baby the car with short drives and under 3k rpm, it won’t get the car hot enough to burn up the carbon build up on the intake valves
Regularly and frequently revving the engine as high as the transmission is willing to take it... even worse, overriding WOT shift points in manual mode and shifting late will cause way more deposits and unburnt fuel to accumulate in your engine and exhaust system.
you will eventually get misfires and have to walnut blast to get back the loss of power and mpg’s.
No you won't.
It’s obvious you never drive in New York or New Jersey. Otherwise you’d understand driving aggressively is a must in the northeast.
I do not understand at all. Driving aggressively is never a "must."
P.S. it sounds like you should be driving a Honda or Toyota since you’re interested in Only driving the car regularly/slowly.
Remember, Mazda engineers "economy" cars, designed for regular driving styles and conditions. They are tuned for efficiency, safety, and driving enjoyment for a "regular" driver. Driving enjoyment without insane power output and unnecessary amounts of cornering grip. Just precise steering, an eager and communicative chassis, with a wise transmission that understands what you are doing and sufficient torque to back it up.
My Skyactiv NA 2.5L in my Mazda 6 is tuned on 91 octane. Yes, I am usually a conservative driver. No, I do not always drive conservatively. I rev the engine out to 5000rpm + about once or twice a week.
This engine and drivetrain was carefully designed around the habits of the average driver, which is the following:
A well designed engine produces usable torque, at usable RPM's, and the transmission strives to keep the engine in that powerband as much as possible. Even though my vehicle is almost on its final tune, the AT still wishes to shift early and conservatively. I do not force it unless there is a rare instance where I actually have to.
Yes, your turbocharged 2.5L makes substantially more torque. 310lb/ft is no joke. I know, because my NA 2.5L on 91 octane will easily make around 210lb/ft at barely 2500rpm, and it is sufficient for me, both when I need the torque or when I am simply messing about, tuning the car, teaching the transmission new shift points, merging, shaming drivers with cars that produce way more torque, whatever.
However, it is still an everyday commuting car. You drive a CX-5. I drive a 6. They never prioritize performance. Anytime you override the AT's shift strategy and shift later than desired, you imply that you know better than the talented engineers who tuned your vehicle. (You don't.)
Drive safe.
