What do you guys recommend on the oil weight? I've heard 20-50 or straight 30wt.

 

Highly debated, there is no real answer because the numbers on the bottle don't mean a whole lot. The general consensus is a 30W at least for a DD and 40W for the more enthusiastic group. I run Mobil1 0W-40, best of both worls in terms of cold starts and viscosity but you will have to change whatever you choose often and even more often given the oil you choose and its driving environment.

 

Ditto,
Mobil 1 0w40

 

oh god, another oil thread.

1990: don't take it personally when this thread gets locked but this topic has been discussed more times then I can even imagine.
Try using the search option and ask it to search "thread titles only".

the general concensus is that 5w-20 is not enough, most people use 5w-30 or higher.
I use 5w-30 Castrol GTX but it all comes down to personal preference.

 

Some helpful info:

I like reading such threads that show engine wear with some known maintenance history.

 

Sorry Jedi54. I'm an F.N.G Thanks for the info though.

 

10w30 castrol gtx

 

If I got a dollar for every oil thread, I'd be a millionaire by this time. 10W-40

 

5w20 or 5w30.

When you search, look for the oil chart from the Australian owner's manual.

ooooooh an oil thread - how exciting . We should take bets on how long before the lock

 

IBTL.......least I got in!

 

The real question is:

Should we use Synthetic or Din oil?




IBTL

 

5 pounds or 7 pounds of oil?

 

10w40 and thats because i read that 24 page thread and have come to that conclusion. i am switching immediately

 

"wd40"

 

Personally I have decided to switch to 0W0 Hyper Synthetic. NYCGPS uses it and swears by it.

 

710 sauce































That is all

 

You would take the advice of someone who drives his 8 on the Brooklyn-Queens Expressway???

 

Oh, but the 0W0 Hyper Synthetic also protects against pot holes and fender benders.

 

We have a literate person. Woo hoo!

 

oh man, not another oil weight thread.

God ...

 

I like how people tried to answer his question without knowing where he is. seriously its important. there are areas of the south and west where i'd probably run 20w50(that he mentioned) most of the year. but up here i stick with 5w20 or 5w30.
