i wouldn't suggest mixing them but whatever works i guess. There's two differant formula's of the syncromesh at the GM dealership, think one is for higher temperatures but can't remember...

Supposedly the Pennzoil Synchromesh is the exact same thing for 1/2 the price. You can get it in 5 gallon containers for $100 http://oilstore.stores.yahoo.net/pensyn5gal.html
