Oil specs

[saabman]

Didn't quite know where to post this... but guessed here might be ok...

I have the opportunity to get some bulk engine oil for my vehicles. I as you can guess I am unsure about the 5.7 Chevy engine... (call to all you GM-ers out there )

here is my oil spec (the bold one I think is the US spec):

15W-40
- ACEA A3-98/B3-98/E2-96 ISS.2
- API SJ/CG-4
- SHPD, VW 501 01/ 505 00
- MB 228.1/229.1 VOLVO VDS, MAN 271

Thanks for your help and ideas...

Go for it.

Any oil that is rated for a gas engine (S for Spark ignition - SJ in this case) and for a diesel (C for Compression ignition - CG-4 for this oil) has to be a good oil.

Normally, I would think your engine might call for 5W20 or 5W30. The 15W-40 will be a little thicker when the engine is cold, and and maybe still when fully warmed up. It may cost a little fuel economy, but the oil will protect your engine.

Yes you are correct the 15w40 will be thicker than the 5w30... I run all my other cars on 10w40 and it is fine so 15w40 will just be not so good under -15°C but as this is rare where I live I might run the risk... apparently slightly thicker oil is good for oil pressure too...
