This subject comes up from time to time and used to be a hot subject back in 01 and 02.

Did the LS1 in the F-Body come from GM with Mobil 1 ?

Or was it only the Corvette that received Mobil 1 ?

Are Vette engines broken at the factory ?


Here is a scan of a post I copied way back in 02 by " fbodfather " (Scott Settlemire) on the old SLP forum.

I think this is what you are looking for.

Engines that come from the factory with Mobile 1 or other synthetic oils are not pre-broken-in. The close tolerances in modern engines allow use of synthetic from the begining. Of course you follow the breakin directions for the first 500 miles and change the oil, etc.

I do not know if GM put Mobile 1 only in the Corvette LS-1's and not in the other LS-1's, but it seems to me that if they did they would have said so for marketing reasons.

I really wasn't looking for anything....just posting some old trivia.

Back in 01-02 many people thought the Vette LS1 was treated special.

Every now-and-then this topic pops up....and who better to settle the discussion than Scott Settlemire himself.

as I recall the LS1 Vette did come from GM with synthetic but the only fbodies to come with synth were if you got a SS or Firehawk from SLP with their synth package included, fbodies did not come from GM with synthetic

Wrong when discussing late 01 and 02 cars from GM. ( This is why I posted the letter in the first post. )

Read the part about late 01 and 02 ALL LS1's ( not just certian models )

iirc, SLP did push the Castrol Sytec at some point for the SS and the FireHawk.

The factory fill on the Vette was nerver questioned.

My 2001 T/A build date was 10/00 and came with regular dino oil. I wonder why the switch later in the build year?
