Gama Goat Crankcase capacity

Ok, I know alot about the GGoat, but noticed my capacity plate is restamped 12qt capacity over the 9. Why is this?

Tom,
I don't know why but all the books say 12 qts. also. If you put 12 qts. in the engine it will be pretty dam- full of oil. If you got a copy of the original Military Specs" back when Gamagoat.com was functioning, you'll notice that it calls for 9 qts.
The books are invaluable but they are full of errors. Got to be careful.

Bumping an old thread,I changed the oil in the Goat this week,and it took 12 quarts to bring it back to full with filter change.

The data plate in this Goat was also stamped 9 quarts,evidently that is without changing the filter?

BTW,I used NAPA Gold 1138 for the filter,worked great!

I don't know what engine oils y'all are using but here's a reminder that Detroit is very specific about not using multi viscosity (IE 15W40) in two strokes. According to documentation that I have read and what the Detroit dealer told me, for normal operating temperatures, they specify CF-2 rated straight 40W. Shell Rotella T1 40W meets this specification and is available at NAPA, Walmart, and Amazon.com...

I'm pretty sure I used Dello 100, formulated for the 2 stroke diesels.

9 or 12 is the 33% difference.
