Anyone ever use AMSOIL Synthetics????

[NismoPC]

I just got a brochure and stuff from Amsoil Inc. out of Superior, WI. They have 80W90 Synthetic GL-4 Only Gear oil as well as Synthetic Engine oils, cleaners, carb spray, lubes, polishes, waxes, etc.

The 1 gallon gear oil is $18.70 + approx $3.50 shipping. Only prob is you have to sign up as a Preferred Customer to order from them. It is $10 for a 6month trial - $20 for a whole year.

Thinking of doing 6 months and ordering some Gear Oil for the tranny and some engine oil.

Any thoughts.
