Was checking on Supercharger Oil and found out from the Dealer that Mobil-! is the same as GM supercharger oil

there was a service bulletin issued to dealerships only... not listed for personal use... that since the lil 4oz bottles are like 10 dollars a peice list... cost the dealership 6.50 a piece and have to be ordered in a case of 12... they listed a replacement option to save on having to order a case for 1 bottle (useful for dealerships that dont sell it very often)...

the GM Replacement oil is... none other than... the one... the only...



MOBIL 1 SYNTHETIC 5 w 30

i know its odd... but the oil is actually the same viscosity so they tested it and listed it as a dealership replacement in lue of ordering a case... just a note for those that are interested...

 

interesting

 

Hmm...

 

This info straight from GM

 

Good stuff! I got some old 5w30 laying around. Some old new that is lol

I still have a complete supercharger oil and coupler kit from when I thought my coupler was bad... Ended up being the flex pipe

 

Interesting! I still haven't gotten around to changing the oil in mine, almost at 80k and I bet it's black

 

I took a couple hi mile Superchargers apart and there was no oil left in them. It had migrated out through the bearings or seals I suppose.

 

Wow. Sucks the info wasnt found out sooner but still good news.

 

Wait are u saying some people use 5w30 in their sc?

Anyway lucky me i used gm fluid to flush mine. Didnt wanna risk anything

 

Its the same thing as Mobil-1 5w30, so you used Mobil-1 5w30 you just paid more for it

 

Mobil one lasts much longer and is what GM said to use.

 

thanks bro i found it!!

 

Post the service bulletin or the number of it. I am interested to see this

 

Here it is. Hard to read but its there

 

Tech Bulletin Update: New Supercharger Oil - GM Forum - Buick, Cadillac, Chev, Olds, GMC & Pontiac chat

 

That's pretty cool. I need to do mine as im getting near 80k. I'll probably use Amsoil 5w30.

 

Been doing this for over a year now on all of the rebuilds I've done.

 

Nice tid bit of info. Thanks!!

I don't plan on touching my blower anytime soon, but this will be good to know for future maintenance.

 

So that thread has the usual idiots... is it 4oz, 6oz, or 8oz?

 

Derp 6oz :P
