Owner's guide says every 10k miles.

But how often do you change it?

SCCAForums

Every 3K for me

BenzoBoi

I usually change it every 5K but if there are times where I go to the track...then every 3k.

Aleksandre

every 8k KM for me

Every six months or 10k here in Canada. Unless I go to the track, then it's done as soon as I'm finished at the track.

Every 3k for me as well.

Every 10k miles, anything less you are just wasting money.

Oil is cheap.... Engines are expensive

That's what I go by.

Pickles

Agree.
I suppose that if the car wasn't being used much, say only a few thousand miles a year, then you might do it more often.
Cheers, Pickles.

5k or 6 months

then it's done as soon as I'm finished at the track.

This car uses 9 quarts, which is almost twice the amount of most cars. The oil lasts longer b/c there is more of it circulating. A change at 3 K is a waste unless you are tracking the car. But to each there own. It never hurts to be overly cautious I suppose. Kind of like asking how often does everybody wash their car? You will get all sorts of different answers.

5K is good. 10K is WAY to long to wait.

Maybe you haven't had an oil analyst done..

Ive done a few and my oil was in very rough shape after 6000-7000km. The base Ph was very low among others.

natman316

is it really better to do it before 10k? I figured the car burns so much oil, you in add some oil its kinda like an oil change in itself.

I changed my first oil at 10k, but might do it more often if you guys really think its worth it.

Roswell

I changed my oil 3 times in 2 years of ownership... once at 1 000km, another at 3 000km & the recent one at 5 500km... what a waste, gotta drive my car more now 'cuz I'm flushing barely used oil. LOL

Jon2007E63P30

I change every 7.5-8k. Oil analysis is very good. I also drive 20k/yr.

Thanks for posting your data, Jon. What kind of oil do you use?

natman316

Jon do you track your car?

also I'm not really familiar with reading an oil analysis table, but in a nutshell thats a good result? haha

CoolBDPhenom03

From our conversations over the weekend, he does/has tracked his car.
