Gear Oil

Post by PMC777 »

Hi, I was looking at a post about changing gear oil and realized I've never done this for my 97 Aspencade and don't know if it's ever been done since I bought the bike used. Scott the administrator suggests using Valvoline full synthetic 75/90, which sounds great. When I looked for it on Amazon, I found Val Syn Power @ $14/qt. Right next to it was Valvoline High Performance 75/90 @ $8.30/qt.
If there's a gear nut reading this, can you tell me if it's worth the extra $5, or will the non-syn be just fine?
Being a cheap bastit that I am, I like to save a few bux where I can.
Thank you in advance for any insight on the subject.

I use Supertech 80w-90 gear oil in my Goldwing (and other shaft drive bikes).

I think it was like $5/bottle?
I change mine every other oil change (10,000 miles) because it is so easy and cheap.

For my opinion any quality hypoid gear oil for a car or truck is just fine. I use the Valvoline standard 80/90 wt.
