Been a while, I am racing a Mitsubishi EVO 9 and have been using Motul 300V 10W40 chrono, am about to tune the car on E85 and have been told that ester based oils are not good with ethanol, if this is the case what would be a good substitute ?

OK going in to Mobil head office tomorrow to take in a sample as they are interested in the "sparkles" will run the 15W50 for a few events and test that as well.

I believe they specify a 5W40 for street and a 10W60 for race applications, although this would change depending on variable cams etc, my motors been rebuilt with forged pistons, eagle rods, ACL bearings etc so haven't really looked in the owners manual for a while.

Yes it does look like a metallic sheen, the best thing is to test the oil which I will do I was just wondering if I should change oils in the meantime, is the 15W50 a good oil ?others here use Castrol 10W60 edge but I thought this was too thick being a 60 weight.

Hi all, have been racing a WRX with forged 2L and using Mobil 1 15W50 syn, I live in Perth Western Australia so regularly see 40+ days in summer. During the 2nd last oil change (2-3 track day) my oil had a sparkle to it, tiny and could only be seen in bright sunlight or under halogen spotlight...

OK picked up some RL 10W40 so will see how I go.

I am using RL LWS oil in the gearbox & have done in previous cars with great success, I have just read (WRX engine builders) that full synthetics can glaze the bore causing blow buy etc, also forged engines do use a little oil so replacing can become expensive but I would rather pay a little...

Hey all, I have been doing alot of reading & am now more confused than befote I stared. I have a track only WRX with a 2L motor with forged pistons & oil cooler, here in Perth Australia we are now in summer and will see temps around 36 deg C, I have been running ELF 10W50 and would like to...
