I'm going with Amsoil in all three. Thanks for the input I have decided to go with Amsoil Severe Gear in the Tranny.

There is three weights of Severe Gear. The 75-90 is about the same viscosity as 20-50 engine oil. The 75-110 will give you a little thicker oil. Some use the 75-140 but I've heard that gear oil that thick will reduce your gas mileage a little. So I recommend the 75-110.

Here is my decision:
1. Amsoil Synthetic 20W-50 (Primary and Engine)

2. Amsoil Synthetic Manual Transmission and Transaxle
Gear Lube 75W-90 (Tranny)

Loyal Amsoil fan here. 20w-50w engine and primary, 75w-90w trans. I also brush my teeth with it and my wife will put a little behind her ears to get me "in the mood".

AMSOIL in all 3, no issues. I can buy it cheaper at the auto parts store than the syn 3, plus it's much better protection.

Nonsence, its made for wet clutch applications. Running AMSOIL 20-50 engine, 10-40 primary and 75-90 gear lube in tranny. Runs like a Swiss clock. 20-50 TO HEAVY FOR PRIMARY AND TO LIGHT FOR TRANNY.

Default HIGH FEVER has broken....
The AMSOIL has cause my scoot to run much much cooler. There is a noticeable change from before. I was running Syn3 and I am extremely amazed that from one synthetic to another there would be this much difference. I am satisfied with this stuff bringing down the temperature.

AMSOIL in all 3 is fine. I do use the SVT 75-110 gear oil in the trans though.
If you can wait a month, AMSOIL is dropping their prices a little bit since the oil prices have dropped.
