does it contain antigel

The performance does have a antigel the winter formula is for extreme cold weather

Is this compatable with def (diesel exhaust fluid) engines. i'm in ca and have a 2011 duromax.

Like other popular additives on the market, the use does not have any bearing on the use of DEF as the DEF is part of the "after combustion stage" of any modern pick-up truck diesel engine. Stanadyne additive is one of the better additives with regards to helping to keep the injectors lubricated during use which also helps to keep them clean and therefore greatly aides in cooling the injectors which are the 3 components of any good diesel fuel; Fuel for combustian-Lubrication of pumps & injectors-Cooling of Injectors, therefore, longer life expectancy! The idea of increasing the cetane rating might be true for some of the additives one can buy, but that is really not the reason to buy any diesel additive! DEF is injected after the combustion process and only used to help dissolve and burn out any particulate matter being emitted in the exhaust.

How often do you use it? Is every fill up ok?

Yes I use 6oz every fill up it is great for the engine and increases power

What is the dosing ratio of additive to diesel fuel?

.26 ounces per gallon of diesel.
