Should I change oil?

[GutsyGecko]

So I went racing Saturday. Made about 80 passes down the strip and did about 180 miles of road course racing during the day. About 400 miles at near redline with the oil reaching for 300+F.

Engine is a modified 4.6 Modular. Oil is 5w30 QS Defy. It now has about 3500 miles on it.

If it were mine, with the miles and abuse on this OCI I would have been changed it 500 miles ago.

All in one day ?????

I'd vote to change it too...

UOA and change it.

Considering you have good money into the build I would spend the $20 and change it...

sounds like normal schedule. OCI should be good for another 10,000 miles.

I hate changing oil and like to stretch intervals, but even I would change that oil.

Where did you do your racing?

 

[GutsyGecko]

I went up to pittsburgh international raceway. I'm going to go ahead and change the oil, but it does still have a light yellow color to it and does not smell burned.

 

[Sonic]

Cool. Yup, won't hurt anything to change it. Then you won't have to wonder.

Not that it matters, but 2,3,4V? Hope you had a good time!

I would change it soon, man. 20 bucks for peace of mind is a no brainer.

 

[GutsyGecko]

2V. Has trick flow heads, and a pretty serious cam.

I think you got your money's worth out of the oil.
Change it.
Maybe use a better oil for your type of driving.
I'd use either GC or M1 0W-40.

Change it..

Change it!

It got an amsoil eao11 filter and 7 quarts of 5w30 royal purple sl with synerlec. Next time it will get amsoil oil. The engine already specs a 5w-20, and has a small oil cooler. I've run up to a 50wt in it, and I don't find there to be a whole lot of difference. I wouldn't even hesitate to use amsoil 0w-20 if I wasn't gonna seriously race it on that oci.

If you are doing 1500-2500 more miles with "normal" driving then that would be when I change it.

 

[Flareside302]

Stay with a 5w30 if your tracking it.. It needs it IMO..
