The time has come to change the tranny fluid in my Koup (just hit the 30,000 mile mark). I've done alot of research online as to different brands and their respective pro's and con's. What I haven't done is to ask the collective minds of the ForteForum group!
So far the top 3 brands that seem to get the best reviews are (in no specific order) Redline, Amsoil and Royal Purple. Now our Koups specify SAE75W-85, which means literally nothing to me as I've never ventured beyond the world of motor oil when it comes to vehicle lubricants. It seems pretty hard to find that exact weight, but I've found several that were close. So I guess my biggest question is, can the weight of the oil vary slightly as with engine oil? IE heavier weight in summer, lighter weight in winter kind of thing? Any help is GREATLY appreciated!
