Default I know, i know

Its an oil question!

What is the actual weight of formula+? Is it an 80W90 gear oil? I am making a switch to all AMSOIL (neighbor 3 homes down is a dealer)

I am going to run 20W50 in the motor and primary of my Electra and thinking 75W140 in the trans.....He told me to dump 20W50 in all three but I want gear oil

Now in the sporty,,,, I changed it in Nov before I put it away and it has SYN3 in the motor and formula+ in the primaryy/tranny...I will use 20W50 in the motor but what is a safe replacement for the primary/tranny?

Thanks again and sorry for asking an oil question!

Just go with 20W50 in both, you will be perfectly fine.
