How many miles do you have on your 3rd gen? Just to give some people an idea of how using the MM isn't going to cause any issues. I only have about 25,700 on my 4th gen, so she's still a baby.I too use the MM and if your worried about going to far between oil changes, use Synthetic. That’s what I do!
I have serviced thousands of cars, never go 10k on a oil change what happens is it starts to cake in the engine, it develops a varnish like appearance. This can lead to premature wear and cause sticky rings, lifters and wreak havoc on the gaskets as well. 5000km should be max or 7k using synthetic.Depends on your drive.
Its eaiser to just to use the oil life %.
If you want a range, it can go any where from 6000 to 10,000 miles. It all depends on the drive that you have.
