Weekend Open Track Oil Change

[cobraboss]

Should you change oil after every weekend of open tracking with 93 octane or for sure with E-85? By the way we are using Amsoil. Tks.

Using quality oil like that, there's no need to change it.

Get an analysis done. Which Amsoil product do you use?

 

[masterjr33]

change it every 8 hours of HARD use. We Figure a hour of hard use is the equiv to 1000 regular driving miles.

Not sure if I agree with you, or not. I've seen circle track race cars at WOT for 4-5 weekends straight using Amsoil Dominator. If not for excessive levels of lead ppm (due to leaded race fuel), the lubricant would still have been suitable for use. With OP using high quality lubricant like Amsoil, he'd be OK racing on the weekend, then driving it on Monday. Have people take Amsoil 5K miles with two track weekends during the oil change interval, and their sample was just fine. Could have been used longer.

This has happened a lot in the GT500 and Boss UOA threads.

What about E-85?

What about E-85?

E-85 doesn't really harm the oil.

Would this also apply when running Royal Purple HPS 10w-30?

You don't get fuel dilution with E-85?
