Is it alright to put gm motor oil cuz the guy at the dealership said it was better to use 10w-30than 5w-30 cause it is like 100degrees hot every day and the mobil1 oil breaks down alot easier help need info if i can use the reg gm oil

 

I would NOT trust that guy...there's a reason why the oil cap says Mobil 1 5w-30 ONLY...I'd be much more willing to trust GM's engineers rather than some guy at the dealership. Also you can be pretty much guaranteed if you run something OTHER than the factory recommended oil and something happens to your motor - bye bye warranty.

I'll leave getting into the details of different oil weights and full synthetic vs other oils for someone else to hash out. Bottom line is, for my SS nothing but Mobil 1 5w-30 will EVER go into that engine.

 

does anyone know how the hell that oil life info thing works on the ss? i never read the manual, but when it gets to 0 does that mean you gotta change your oil or what? i was changing it @ 3000 miles anyway, but that thing is wierd

 

Have the oil changed around 15% and the service dept will reset the meter for you.

 

That is the most INSANE thing I have ever ever heard. The car comes with Mobil 1 from the factory and should be changed with Mobil 1.

Mobil 1 holds up to heat almost indefinetly while regular oil breaks down.

Wow I can't believe someone told you that, it's just plain wrong.

 

The oil life system is based on calculation made by the computer as to operating conditions, driving habits, ect. It's purpose is to keep people from wasting oil by needlessly changing their oil every 3000 miles.

 

damn that's pretty slick... so i guess i don't drive it as hard as i thought.... 77% @ 1800 miles

 

85% at 1250 miles...

 

69% @4200 KM

I was looking under the hood the other day and i didnt notice a dipstick, is the oil life system measuring if your low on oil?
