It would be nice to have more info on every product out there and a lot of info is from individuals who submitted samples and paid for testing on bob's site. The folks at Bob's site do this a lot. The vast majority of comments on Bob's site seem to be more focused to oils than gear lubes. When it comes to gear lubes Royal Purple @ GL-5, Redline @ GL-6 and Mobil @ GL-5+ are all good as is the Amsoil GL-5 product.

I like Mobil because it's easy to get. RP;Redline and Mobil-1 are available only in 75W. Amsoil offers a GL-5 80W. All are fine as the difference between 75W and 80W is only 6% and all are rated 90 at the top end. The GL ratings mean more than anything.

You simply can not ignore the fact that Mobil-1 exceeds GL-5 and Redline is GL-6. Redline would be one product worth ordering in as you only need a small amount per season if you decide to go with it.

Another drive oil question can you run them to cool. I have an Alpha drive with 300 HP (not quite the HP most of you deal with) and a halo type drive shower. If I go with synthetic oil could it run to cool?

Synthetics will flow better than conventionals at cooler temps. you will be fine.
