ok im running mobil 10w 30 fully systhetic.and i was wondering what everyone else was running.also now winters commin soon arn't you supposed to switch to like 5w-30(just curious)royal purple is the best but at almost 8 bucks a quart does anyone run that????

so what do you guys run???

and do you change during colder temps???

 

I run 10w-30 valvoline conventional oil in mine.

 

You should run 5W-30 in it all the time... stay away from 10W-30...

And I run 0W-30 Mobil1 year-round btw... for those who want details, let me know.

 

hmmm
i wonder whats better.like RP is the best but i wonder whats 2nd

 

i want details spill it neon expert right here.LOL

 

I'd guess Brad-Penn is second.

 

never heard of it???

 

Mobil1 0W-30 is thinner at startup than the 5W-30... obviously.

But the 0W-30 is actually slightly thicker at running temperature than the 5W-30...

That being said, who wouldn't run this year-round? (Assuming you don't live in Death Valley).

 

It's either amzoil or brad-penn for second. I know guys that drag race hemi's and they didn't like the rp and are sticking with brad-penn.

 

so this is good to use all year round???
