See tips 5 & 6.
I use Rotella 15w40 year around here in VA.
Pump gas is fine, but if you do not burn a tank full in 30 days, you need to add a fuel stabilizer like Marine StaBil or StarTron to keep the ethanol from separating.
I've used ethanol gas and fuel stabilizer in old tractors and cars now for 20 years w/ no problems.
