Mary, diesel #2 is the fuel for the fuel tank. DEF is Diesel Exhaust Fluid which newer pickup trucks and large trucks must have to clean exhaust emissions. Mixing the two would ruin the engine. DEF goes into a separate, smaller tank. Mine for example is 5 gallons about every 5000 miles, which varies depending on load.Ok, I must ask... may be a couple of stupid questions. I have seen the banks of DEF at truck stops but is there a difference between the Diesel Exhaust Fluid and Diesel #2? Or is the different name just to keep the riff raff (and those of us without magnetic collars) out? Also, the link above shows a ebay listing for filing a reusable container. Can you just pump it right into your tank?
Deisel is pretty cheap here but I've never seen it lower than gas. Always almost a $1.00 higher.
Almost. Here in Billings MT at Sams Club diesel is $2.31 while gas is $2.19. This time last year it was $3.99 in Missoula.
