Is it true that almost all Evo drivers go with Mobil 1 (of course pure synthetic)? Or is there a better oil that some of yall use to produce better numbers or that yields less wear and tear on the engine?

Just a quick response is fine.

1. Oil you use
2. Weight
3. Seen added proformance compared to other oils?

 

I'm sticking with what Mitsu recommends personally.

 

people will swear by anything, but i use castrol.

no real reason, i just use the weight that Mitsu recommends.

 

i just let the dealer do it for me.. they give me a full synthetic evo oil change and tire rotation for 40 bux.. its great!

 

that's a great deal ... the oil alone is nearly $40.

I'm going to try out AMSOIL on my next change. I've heard that they can have issues with silicon bits, but only from one person.

 

I haven't messed with other oils besides factory Mobile 1.

 

I've used Mobile 1, Royal Purple, and Q Advanced.

My honest assessment is that there is little to no difference between the three. Q Advanced seem to get dirtier, quicker but I can't really be sure without any kind of empirical evidence.

All three brands worked well. I used Q Advanced for probably 9,000 miles. Royal Purple for 3,000. And Mobile1 for 6,000. I am currently using Mobile1 in the vehicle, but since I avoid the dealership like the plague, I will probably switch back to Q Advanced.
