Engine Oil

[awd-drifter]

Hmm..read this whole thread and it seems people are using Amsoil and M1 either the 10w30 or the 10w40. Good read by the way. I have a few questions though;

(1) Does it matter which oil (amsoil, m1, pennzoil, valvoline...all synthetic of coarse) I use for the mods I have and will it effect performance?
(2) I was told not to really change from (x brand) to (x brand) because of the different "ingrediants" they use for each oil...is this true? Is that why when a few of us change to different oils, there's suddenly an issue?

In my personal experience, I've been using M1 10w30 since I got the car. I've literally changed the oil RIGHT under the 3000 mile mark every time with the NAPA gold oil filters. My head currently has a leaky valve, so I'm guessing that is why the car loves to eat 1-1.5 quarts every 1500 miles. Haven't had any issues with the engine though. Head still looks pretty spotless. I will post pictures of the head soon once I get to work.

No idea what your mods are so can't answer that.

No idea what sudden issues you are referring to as I've never experienced these sudden issues you speak of, and i use different oil brands regularly (I buy what ever is on sale). So again can't answer that.

lol..early morning ftl.

as for my mods; e316g, 550s, 190 pump, 2g mani, fmic, 3" exhaust system, ported o2/2g mani, dsmlink v2(untuned still! ). The car has been doing fine for the past 3 years so I'm pretty satisfied with m1 10w30. Haven't driven the car since winter came though.

As for the issues for your main car and not a DD, I was reading other posts on here saying that when they switched oils, one of the members here got a spun bearing, Goodhart mentioned one of the Supra guys (mk3) getting the same thing. I haven't gotten any issues because I haven't switched brands of oil just because of the different "ingrediants" x-brand has compared to the other x-brand. As for the DD, I too buy what ever is on sale
