I am an Amsoil guy and need to know what to use in my 8V Griso for the engine, Transmission and differential. Has it changed since back in the day or is there something better. All opinions welcome.

What matters is viscosity. Check the owners manual and use the recommended weights. Personally I'm not an Amsoil guy, I tried it and found it lacking, but it is your bike and use what you want.
Hey John, I used to run Amsoil in my Jackal and Le Mans III, it came highly recommended from Todd E. Can you tell what you use and why, just looking at options as I just hit 1K. Thanks again, Tom
OK I will. I tried it in one of my bikes. When I went in to do a valve adjustment the valve rockers and all were completely dry. No oil film. Since most wear is at start up I switched back to Mobil 1. It leaves a good film of oil on the metal bits so no dry starts.
That is a valid option, use a cheaper mineral based oil and change it more often. But a good synthetic oil can deliver better performance and last longer, even in a transmission or gearbox. I use a better quality oil and change it as often as it needs changing. My version of it is to spend the little bit extra on a better quality oil and change it as often as it needs changing. It is a lot cheaper to change fluids than to have to replace hard parts due to wear.Going to chime in here, I 'get' the use of synthetic in a high carbon and varnish environment like an engine but...... in transmissions, and I really am looking at carcs here I don't see the point.
Much noise has been made of water ingress in carcs and emulsification.
I believe that it's better to use half the price mineral gear oil and change it as often as the engine oil to keep a weather eye out for contamination rather than to leave it in longer trusting to synth properties and risk not knowing.
