FWIW: ask around.. 3K is borderline, if it is a tight sweeping right hander (keeping in mind that how tight, speed, and lateral g's are all a factor, so NO one RPM can be made "THE" limit.. Typical onramp clovers at 3-3.5 have proven fatal more than once.

What i'm getting at is if these failures were prone to happen at such low rpm then many, many more people would have blown their engines.

Just look at how many people autocross regularly, or even how many track race their cars. Tell me you don't pull massive g's in an autocross.

Didn't the roush test find that the least amount of oil was in the pan @ ~5500 and above?


And FWIW, there's a bunch of people here who run regular dino oil as long as synthetic in their engines as per the recommendations of blackstone labs.

It's not as much a necessity as so many people make it out to be.

I'm not saying the engine doesn't have an oiling issue. But driving the car like that is a waste. I can't name anyone who slows to 2.5k or less on a right hand turn of any type, unless it's a 90 degree. Hell, 3000-3500 is still taking it easy. I've been driven around gingerman raceway in an SVT with race slicks at redline in every gear (until 4th)...right turn, left turn...whatever. And that car was autocrossed regularly. And it was also properly maintained. AND it's still running. And for every 1 car who spun a bearing at 3000 rpm there's atleast a dozen more who were treated like i just mentioned and are fine.


Relax a little...
