R&L's C6

So I got this this newsletter from Corvetteforum and it had an article/advertisement about synthetic oil. Mistake #4 says using synthetic oil to break in your engine. Doesn't our cars come from the factory with synthetic oil when new?

I thought so.

Hey, IB (the owners of CorvetteForum) are consistently advertising that we need to put off-road truck mud tires on our C6. Just watch the second thread titles. At this moment the current second "thread" ad is for SUV tires. ("Looking for a reliable tire to get you where you need to go? The CROSSTEK® CUV is designed for crossover vehicles and compact SUVs.") Who is stupid enough to think someone is looking for SUV tires for their C6 or any generation Corvette for that matter? They are idiots when it comes to knowing their market. (Ooops, did they hear that? ) I don't bother reading any of their crap.

As far as synthetic vs. dino oil, the C6 comes from the factory with synthetic. Evidently the engineers who designed the C6 know more about what the C6 needs than Joe's generic recommendations. Joe is correct though that when rebuilding an old engine it is better to use dino oil for the break-in. The reason is you use less accurately matched parts rebuilding an engine than the factory does when building a new engine. That means you need some wear to get them to fit better and dino oil gives more wear.

Bottom line - don't pay any attention to any ads coming from CorvetteForum unless they specifically say C6. Most of their ads have nothing to do with a Corvette and the products recommended will do far more harm than good.

All vettes since the LT1 engine in 1992 have come with synthetic oil.

Too late to worry about it now..........

That's for sure.

Yep... you're screwed and it's a known problem..
Why in 250,000 to 300,000 miles from now, you could develop
engine problems from using synthetic oil too soon in your engine..
Good luck to you !!

I would say not/

" Are our engines doomed from the factory!!!!!!!!!!"

Yes....with continued use your engine will fail at some point in time. I wouldn't, however, use non-synthetic oil in a Corvette engine during the break-in period or otherwise. Concerning the break-in period, there's a school of thought that says it's essential to run your engine hard right off the bat in order to properly seal the rings.

Years ago, when I replaced my OEM engine I thought about a gentle break-in period for the first 500 miles or so. Well, that wasn't to be. The very first thing done with my engine was to blast it repeatedly on a dyno! After 6+ years of hard track use my engine hasn't so much as hiccupped. In fact, it now puts out more hp and torque than it did when it was new.

So now you want a fender that matches your car AND and engine that will last . . . . getting a bit greedy in Minnesota aren't we ???

R&L's C6

Well.....MN is the welfare state.....

Interesting the way you captured this. I did the Museum delivery on my '08, and the one thing I noted towards the end of the line was how hard the cars were treated at the dyno. I asked my 'guide' about this in light of the 500 break-in period, and because there was an International writer touring the factory with me he said he'd talk to me about it later ... as in wink-wink ... nudge-nudge.

michaelinmech

Well ????? What did he say later ??

20 years ago, it was common knowledge that you never break in an engine with synthetic oil. We always ran normal oil for the first 15k to 20k, then switched over to a synthetic.

I don't know what has changed, but, like someone else said, if these came from the factory with Mobil 1, as I was told, then it is too late to worry about it.

Moved away from there in 1982 and I do not miss the high property and state income taxes I had when I lived there that comes with a welfare loving state.

PS: love your new avatar showing off the two-tone paint job, GM should use it in their ads.

20 years ago we didn't have the machining technology and metal alloys we have today. These engine are built to last. 20 years ago they didn't have 100,000 mile warranties. Then Corvette tells you to go out and use your "Launch Control" and run the snot out of it. They are pretty confident they gave you a good motor.

Your factory engine doesn't require "break-in". Do a little research if you want specifics as to why.

However it's best to take it easy on your drivetrain and to some extent brakes for the first 500 miles.

Yes, they does.

I imagine those engines will bite the dust after 200 or 250K miles of hard use. What a shame.
