Just purchased a 99' series II and I'm thinking of using Amsoil products in it(oil,trans,diffs) is anyone using Amsoil products or other synthetics? By the way the 99' has 55,000 miles on it.

I just put Redline synthetics in my "98 LSE (except engine oil ). I've used Redline products in all my race and street cars. ( I do use Swepco in the 911 trans, the synthetics were too slippery for the syncro rings !! ). It is fairly easy to find at most race shops and some parts stores. I buy mine from our local race supplier. I like something that I usually have on hand, and if not I can get it quickly. On my street cars I use Mobil 1 for the engine since I know it is readily avaliable everywhere. On my track 911 I use Valvoline 20-50 dino since I change it so often and the car takes about 12-13 qts. Just my 2-cents, there are probably more knowlegable people on lubricants who can tell you more about the benefits of synthetics. Some advocate dino and change frequently. On the Porsche list this ALWAYS starts off a BIG discussion from both sides !!!!

Wow, talk about reviveing an old thread!

I posted that way back. I still use all synthetics except the trans, i don't know why, but like you I usually get Mobile 1 from the local store unless I can plan far enough ahead to order the Amsoil.:beer::beer:

P76rangie was patient enough to take me through the differences in engine oil. After I stabilize everything I think I will try an oil with a different makeup to give me an edge in this hot climate. I'll do the same with rad, fan and viscous improvements probably.
