What motor oil (not brand!) weight and numbers should I use on my GSR with 40k miles and turboed?

 

You can use any fresh oil you want as long as you change it on a regular interval, I suggest 3k to 7.5k like anyone else said. 3k for dino, 7.5k for syn.

 

5w30 more than likely. And I don't know of any turbos that don't require synthetic. So you're probably best using that.

 

i run 5w30 on my turbo gsr. works well for me. i change the oil every 1500 miles

 

5w30 in the winter, 10w30 in the summer

If you've got any oill consumption problems, 10w30 is a safer bet.

For a turbo'd car, I'd change the oil no less than every 2,000 miles.

and whoever said 7.5k for syn is out of your mind

 

eh not necessarily, i hear you should change the synthetic oil every 4000-5000 miles, and change the filter 2-2.5k miles. I hear changing the synthetic oil too early is actually early.

Some folks have sent in their used oil to be tested and have found some interesting results. I forget the exact numbers, but the oil they were using was still definitely good-to-go at 3000 miles. The tester recommended retesting after another 2000 or so.

wouldnt changing the filter require changing the oil anyway ?

Um NO.

e46 BMWs run single 10,000+ miles oil change with synthetic oil. I'm pretty sure that can be said for most other cars using synthetic oil.

 

ok i been using mobil1 full syn 10w30 and I just read my stock air box and it says I should use 5w30. If I start using 5w10 will it make any difference? or am I better off just sticking to 10w30. and also I live in socal san diego.

 

vavoline maxlife synthetic high mileage 5w30 =P i only run high mileage because my exhaust smokes alot and with the high mileage it doesnt burn off oil that much... its pretty good =P

Why not an all Oil based web site for all of these conflicting opinons

 

10w30-40 for summer 5w30-40 for winter, dont get your panties in a bunch.

 

well im at 158,xxx miles so would 10w30 be more sufficent than 5w30?

 

regular oil will just do!

no need for the high expensive bull ****... oil is oil...

my choice 10w-40, burn about 1 qt every 1500 miles...

Exactly, dont believe the hype when it comes to OCIs. The only proper way to determine the OCI on an oil is to have a UOA done. I had a UOA done on my Chevron 10W-30 dino oil at 6K miles. The report showed that the oil was still good and that I could have gone even longer on the oil.

As other have posted, check out the forums at BITOG. You can look at real world statisitics and tests on oils in the UOA section. There is also good info in the Oil section.

not bashing hence the face at the end of my comment. just seems like a lot of teg's burn oil before the 5k mark, its more of a mental thing for me...my brother didnt change his oil for about 7500 once and it burned all his oil dry and being the lazy *** he is he ended up throwing a rod...and yes i know syn is supposed to go up to around 8-9k...but its oil and it only costs me about 20-25 with a filter to change my oil so id rather spend the money then worry about any problems

EXACTLY

My last autotech instructor always said "oil is cheaper than motors", i'll stick with that philosophy as well.
