Hey guys,quick question.
i have a 2004 sedan AT
And i am curious on what type of engine oil to use 5/30 10/40 etc,i am a more of a spirited driver and i head the 10/40 is good for that,or 5/30 is more of a normal driving(temperature wise)
and what brand do you use,thank you.

 

i use amsoil 5w30 all year round

 

just an update.
the car is being driven in Vancouver,so the temperature never hit more then -2.

 

0W30 German Castrol.

The 5W30 Castrol Edge is okay too, but not as good.

 

I just picked up 10 qts of german castrol on sale at Autozone. I have heard great things about it. Tell me, prinny, when you started using it did you notice a loss in fuel economy due to the fact that the GC tends to run on the thicker side for 30 weights? Doesn't matter to me... protection is better than a little fuel economy in my mind. I have seen the UOAs on this stuff. Quite impressive.

 

I use 5w30 conventional motor oil. Castrol
