i use quaker state horsepower synthetic.

 

What did you use before PP and did you burn before? I wonder if it's because both PP and Mobil are mostly Grp III base stocks?

 

A mix of Amsoil ASL/ASM 5w-30/10w30. That burned ~1qt in 5k. Its because I have a revup engine. I only ran the OEM oil for 2k, but I burned 1/2qt then also. I'm just going to live with that amount of burn off.

 

0w-30 german castrol... if you can find it

 

I use Mobil 1 5w-30. Not a single complaint...

Motul > Royal Purple > Amsoil > Mobile 1

 

Got some data to support that? Amsoil is pretty highly rated

 

I'm sure this is just your personal preference. Doesn't seem like anyone has real facts & data to prove what's really more effective.

Mobil 1!

 

No real data, but on my revup motor, Mobile1 is always down to maybe half quart (if not less) when I change the oil and Amsoil gets pretty low too. It's never that bad since I've been using Motul or Royal Puple... and it's always full synthetic 5-20

 

GC FTW!!

 

dare I say I use motul 8100?

 

Ive been using Mobil 1 but have been interested in MOTUL as well. Any MOTUL users here with comments?

 

Found some german castrol today at Auto Zone. Wondering if I should get this, I have an oil change in about 900 miles.

0w30 is pretty thick so would this be OK in the summer time or am I retarted about motor oil and that has nothing to do with anything?

 

^ a 0w30 will be less viscous than a 5w30 during cold starts; you will be fine.
