'05 Mitsu Evo recommendations

[DaveWRX]

Factory recommends 5w30 Mobil 1 at 5k miles, which is what I've been doing--either regular M1 or Extended Performance. Car now has 106k miles. I drive it hard pretty often. I autocross it and it's my daily driver. Not burning any oil. This is a ~300 HP turbo inline 4.

So, should I stick with M1? Regular or extended? Or is there something better? How about M1 0w40? Or 10w30?

regular if you're only doing 5k oci's.

Sounds like what you are doing is working well for you.

If that's what the Factory likes, I'd stick with it. Perhaps 0w40 if you're feeling adventurous =P

M1 10W 30

I'd go with Mobil 1 0W-40.

Mobil 1 5W30 is pretty stout stuff, absolutely nothing wrong with it in your application.
Autocross just isn't hard enough to do any real damage to the oil (your oil will sometimes never reach full operating temp on colder autocross days depending on the number of runs and time permitted to cool-down between runs.)

I would just run it in either the regular or extended depending on which oil was on sale or had a special running at the time.

Mobil1 10W-30 High Mileage for its better HTHS viscosity and ACEA A3 rating. Here's a uoa on a newish modified Evo that ran M1 5W-30 EP.
I think there are some others in the uoa section, but I couldn't find them.

Any turbo or supercharged car should use syn. M1 would be good. Turbo's gets super hot and IMO oil choice is geared more at protection of the turbo and frying the oil that goes through the turbo itself

A lot of European high performance cars spec the M1 0-40. It is great with turbos, and extra heat from racing.
