The FINANCIAL -- IRVING, Texas. In recognition of its longstanding collaboration with one of the world’s most storied high performance automobiles, ExxonMobil has announced the 15th anniversary of the relationship between the company’s flagship Mobil 1 synthetic engine oil and Corvette.

Since 1992, Mobil 1 has been the factory and service fill lubricant for all Corvettes manufactured by General Motors. During this time, more than 490,000 Corvette vehicles have left the production line filled with Mobil 1 engine oil.

 

Question for you, your quote say"Mobil 1 has been the factory and service fill lubricant for all Corvettes manufactured by General Motors.''

Who besides GM is building Corvettes?

 

This is true, I remember when I'd first heard about it happening (must've been in a magazine or something for the internet was in it's infancy back then LOL) and I was quite impressed as I was using Mobil 1 as well in my Mustang LX 5.0 at that time.

 

 

When I bought my '02 Vette, it did not come with Mobil 1 from the factory. The dealer did a free oil change to Mobil 1 at about 1000 miles. Story was that Mobil 1 was not good for an unbroken-in engine. So how come it is now?

 

You got a rare car if it did not come with Mobil 1 from the factory.

I would call up Barett Jackson and sell it at the next auction.

Mobil1 is factory oil for a long time before you 02 was made. Get a new dealer, yours is perty dumb.

 

Since you asked, 34 other countries have built/are building Corvettes.

And any one of them would "blow" the GM Corvette away.

 

So are they coming out with 15th anniversay limited edition bottles of 5w30 in collectors edition plastic jugs?

How about they give a free case of oil to all vette owners. Just show your ownership at the checkout counter or a mail in rebate.

That's how you celebrate an anniversary.

 

You got me there, guess I should have said LAND Corvettes.

I was in Navy in mid 60s, but on a cruiser. Their a bit tougher than a "wet" Corvette"

 

Only if the bottles have a picture of a 'vette on it.

 

As I understand from GM promotions, the engine is initially run with a break in oil, which was not specified, then drained and refilled with Mobil 1. Synthetics are too slippery for an initial wear in, especially those with Molybd. additives. It is best to consult an engine builder regarding what oil to use for this application.

Edit: The reference is a movie from the Wixom plant. There are a bunch of them on the web. So, you'll have to look it up yourself. And did you ask any engine builder before you hit reply? For your next engine, why not run it in on synthetic and see what happens. Do you have any engine building experience?

 

Really!! Post a link, quote, name, date, etc from GM promotions confirming this.

 

Must be a full moon!

Been some great reading on this thread.

 

That's my point, they have not been coming with Mobil 1 since '92. In '02 thay did not have it (hence the free oil change), in '05 & '07 they did (no free oil change).

 

With all due respect, are you not reading the piece from OP? Corvette started in '92 with the LT1 (new LT1) and in that same year, the sticker "Mobil 1" went in the engine compartment along with the oil in the crankcase. They haven't changed from that since then.

 

My '02 did not have full strength Mobil 1 from the factory. May have been a half synthetic/blend. Got a free oil change from the dealer to install the Mobil 1.

 

This is contrary to all other data available.

So, what makes you think your 02 didnt have full synthetic M1? Did you have it analyzed, or was it something the dealer told you, or?

 

Any way to prove that? To be honest that sounds like total .


Is their anything special about your car that it would have different oil in it than other Corvettes?

Many/most dealers give a free oil change to a new car/truck purchaser for their first oil change.

If I were you I would contact the Myth Busters.
Sure sounds like you have a flakey dealer

 

Once upon a time, it was true that engines break in quite a bit, and you didn't want to run synthetic from the get-go. In particular, the cylinders were honed fairly roughly, and the rings had to wear the honing marks down to seat in to them.

I experienced this personally; built a Formula Vee engine and filled it up with Amsoil. Thing didn't run worth a darn. We tore it down and found no signs of break-in at all. We cleaned it up and broke it in with "cheap" oil, then filled with synthetic - we were all believers after seeing that engine.

These days engines are built much tighter, and there's a lot less break-in required - some would claim none at all. Nonetheless, I believe there's still some. I've run two LS engines from zero now with synthetic oil, and both of them seem a little stronger after they've got a few thousand miles on them.

 

Some of you guys really make me laugh!
