This is what a lot of us have been doing for decades.

You guy's should be fine with any name brand synthetic oil. Just be careful with Mobil1 5w-30 it breaks down to a 5w-20 in a short amount of time.

Amsoil's site has some good info if you want to read.

I would think that the 7500 miles should be fine with a good oil.

My OEM GT engine went 154,000 on dino oil with no bearing noise or other issues. I replaced it for oil usage (rings). But I would go as far 5500 miles on the dino oil in the winter time and 3500-4000 miles in the warmer weather. BTW most of my miles are at highway speeds.

The main thing is keep it topped off. Don't go 7500 without checking the oil level.
