Given how cheap DEF is and how easy it is how to fill, I wonder why automakers have the perception that consumers don't like to fill them up.

- makomk 9y agoAs I understands it, the US restricts how often cars can require DEF top-ups so strictly that it's impossible to meet both the emissions requirements and the top-up interval requirements with a reasonably sized tank.
- jessaustin 9y agoOur truck has a DEF tank that's smaller than the fuel tank, and requires refilling about a tenth as often as the fuel tank does. A nearby truck stop has a DEF dispenser, so it's no more difficult to fill than the fuel tank. Of course this truck probably emits more NOx than an emissions-compliant diesel car would, but it also burns about twice as much fuel. The real problem with DEF in passenger cars is those "luxury" manufacturers that require a special tool to fill the DEF tank, as if DEF were some rare or dangerous substance.
- briffle 9y agoMy pickup (Ram 2500) gets about 1200Mpg of DEF. When I am towing our large RV trailer, it drops to 800Mpg. I drove the RV from WI to OR on about $10 of DEF. I don't understand why some people think it's a big deal.....
