Wow, why was it changed with only 3281 miles? Especially with a TBN like that!

Most of the Corvette owners on that forum still stick to 3000 mile intervals. In fact some of them change it even sooner! A lot of them might only put 2 or 3k on their cars each year also, so they end up doing one oil change per year.

It looks good but is a waist of money. The owner will probably say that it is cheap insurance.

I agree with the that thinking. I drained my Step Mothers Nissan it had 400 miles in 1 year of service.Thats less that 50 miles a month.At 88 years she hardly drives.The time element I abide by but many don't.

Looks good but definitely a waste a money. I know 3 guys at work who have Corvettes. They all drain the oil at 3k miles. Really a shame.

If she only drives 400 miles per year, I bet you could leave the same oil in the engine for ten years and not change it, and that engine would still not die.

So, how long was the oil in service? Any track time?

Is the silicon not rather high? What kind of air filter?

Not all of us corvette owners are waxers and change every 3k

I throw my results at those guys all the time and I just get ignored.

IMO if they are going to change every 3k they might as well use M1. They are still throwing money away, but it would be less money with M1.

I have no idea on any of that, since the used oil analysis wasn't even posted by the owner of that car, but from someone he knows.
