I have been buying this at Sam's Club for the Company trucks. 2.5 gallon container is $10.88. This in Mn. Sounds slightly cheaper than some of the other sources.

The Pilot fuel station (truck stop) here has a DEF pump in the same island as the diesel pump. They get $2.899/gallon

We use so little of it that the price difference isn't really significant.

Except when the M-B dealer charges you $15 per half gallon to fill your tank.

Mike, I hadn't even considered the dealer. I only go there if something is under warranty.

Is the dealer actually charging that much of a markup or are they charging an absurd labor fee like they do for any labor? I never have had them do DEF before so not seen how the receipt for the "work" looks like. I once paid a Ford dealer something like $85 to change out a burnt tail light bulb, that was $83 in labor(1 hour rate) and $2 part .... I was an idiot to not ask ahead of time.

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.

I asked for a quote to change the fuel filter in my '06 CDI. $199 they tell because it is"very difficult"!


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 typically buy 2.5gallons for $12-13. Thought of buying a 5 gallon new gas tank and home depot and filling it up at the truck stops but not really worth it right now.

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....

mikemargolis

That is good. My local dealer is still insisting that they fill the DEF tank of every car with the 1/2 gallon bottles, which are $15 each.

I told the service advisor that he should wear a black mask when suggesting that.

Mikemargolis, I just checked your ave MPG. Do you do a lot of city driving? We're in a rural area and drive mostly on twisty, hilly, two lane roads. I don't baby the car and my wife has a heavy foot, yet our dash computer says that we've averaged 35.5 MPG over the last 20,000 + miles.

mikemargolis

I use fuelly because it actually calculates the mileage using miles and gallons pumped.

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.

skromfols

Mike, I'm not familiar with fuelly. Can you tell me what it is?

Thanks I'll check it out.

My E350 overstates about the same as your Mike, will show 35-36 per tank but usually get 30-33 calculated at the pump....

I have found that AdBlue is consumed the most during city driving. Very little is burned on the highway. During my past 10k miles, I only used about 1.5 gallons of DEF. I do a lot of highway driving.

I'm really curious about filling my DEF at a truck stop at one of their dispensers. Has anyone here ever tried it?

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?

Mbenz260e

If you do a search there is someone with a tutorial on how they did it. But basically create a funnel from the 1/2 gallon container MB sells and do it slowly. I am thinking may be easier to just buy a 5 gallon fuel can, and fill that at the Truck Stop?

Flyingman

Forget about it. Went to my local auto store and bought a box of 2.5g DEF and 2 X 1 Gal bottles. The 2.5g box comes with a really handy flexible spout.

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.

The DEF tank's capacity is 8.2 gal. My GL 350 used 2.5 gal over 6600 miles of mixed highway/ town driving. Very easy to fill with 0.5 gal MB fill container and refilled with Wallmart 2.5 gal tanks.

hubert

I got 4 bottles of original mb def that I'm giving away for free just come and pick up in queens ny. Brand new in boxes. I had it leftover from when I had my gl350.

andedave

Walmart now has their own DEF brand. Just got a 2.5 gal. jug today for $7.88.

Micah / AF1 Rac

Local Bucees gas stations in Central Texas charged $2.39/gallon...my Sprinter held more than I expected but like others have said very little is used in highway driving which is 90% of that Van's life.
