DEF pricing
With that said I think simply getting it from any auto parts store is a cheap enough route for me. I would be curious if the pump nozzles for DEF at a truck stop fit right into my 2013 ML. But as of yet just never been around a truck stop in it to find out for myself. I am assuming it does not fit though.
Bought oem filter online $23+. No tax, free shipping. Very basic tools & skills required.
Cheers,
Regarding DEF, everybody except the truck plazas are gouging on the price...

I got lucky last week I think, took the GL350 in for Service A at the dealer, told him to skip the AdBlue but he quoted my $186 all in with DEF, Tax etc. etc. which I didn't think was too bad....

I told the service advisor that he should wear a black mask when suggesting that.
I reset my dashboard at every oil change, and right now, with about 5000 miles in, it's showing 34.4.
That dashboard computer is notoriously inaccurate.
Try fuelly, my friend. Or at least write down half a dozen tanks and gallons and do the math. You won't be anywhere near 35.5 if you've got an E-350 diesel like mine.



I know I can get the 2 1/2 gal jugs at any auto store, and get the small special bottles at one of the dealers (MB, VW, BMW) with a special no spill twist spout.
I'd think we could just fill up the DEF at a Flying J Truck Stop, next to the Diesel Pumps?

Just opened the fill cap, inserted the nozzle and poured in the full 2.5 gallons of DEF. No idea how much I'd need so tried to add one more gallon. It quicklt overflowed so I stopped, spilled a bit about the side and wheel. Just wiped it off with a paper towel.
So about 2.6gallons in 7k miles. I think the DEF tank holds about 6 gals.
I paid $14.99 for the 2.5 gal bottle and $6.99 for the 1 gallon. So $15.00 bucks for what the dealer charges about $200.
