Fuel Loading Chart

[cessnadriver]

Hello ALL.
Here's my question.
I have a 1965 C337. I'm going over the owner manual, specifically "Sample Loading Chart".
On the loading graph it has one line for "FUEL". On the line at the 32.3 (load moment) "36 gals Max. Aux tanks" AT the end of the line at 82.8, "92 gal Max."
When calculating the fuel load, I add the 36 gal and 92 gals, 128 gals (#768) TOTAL.
On the "Moment" column do I add 32.2 (AUX) and 82.8 (STD) together, OR do I use the 82.8 for both fuel loads. This is probably 'CG 101' for most of you but this is a new aircraft for me and I'd just like to understand better!
Many Thanks as usual!!
