Is there any difference in the diesel fuel that is pumped from the island where car and pickups fill up to the ones where the larger tractor trailer riggs fill?

 

Same exact underground tanks most of the time and if they aren't the same tanks they are filled by the same tankers.

 

at the same station, prob. from the same tank - same fuel.

keep in mind, however, there are often BIG differences between diesel fuels from station-to-station, state-to-state.

i gained 10% mpg when i moved to OR from CA - CA fuel is loaded with additives/junk. i've had similar/different experiences with "#2 diesel" between states/stations out west...

Thanks for the info. I was told once that it is better to fill up at the big rigg pumps because they are fresher fuel. And then I was told not to fill up at the big rigg pumps because they are not filtered as well as the diesel for the trucks and cars. I thought it would all be from the same tank but I just wanted to know if I am being fed a bunch of opinions rather than facts. I appreciate the answers.

 

I agree , myself & others are noticing difference here locally .

 

I am currently trying to verify differences in mileage between my 2 local stations, early data indicates almost 2 MPG difference between them, but before I make a statement I want a few more tanks run through.

 

Fuel in the truck stops tend to get turned over more frequently. While truckstops do buy more fuel, they have to refill their tanks more frequently, so the fuel is less exposed to condensation, algae, sediment, etc.

Not possible! ALL modern diesel fuel systems have the same tight requirements for water content, additives, purity (filtration) levels, etc.

The biggest difference between auto and big truck diesel fuel is the amount of road tax. Big trucks pay more road tax.

Yes I forgot to mention that.........that is a good point........higher taxes.

 

The tax is not on the fuel it is paid by your mileage in each state and where you buy it, it is divided to the states you run in.

 

ive noticed a difference in mileage between two different stations- one being shell and the other being a CIF (carroll independent). the carroll fuel doesnt last as long as the shell- i seriously am at 110 miles at 5/8 tank. if i had shell in the tank id still be around 7/8 tank. but i got carroll this weekend cause it was almost 30 cents cheaper.

 

there are fuels with different sulfer amounts. a friend of mine has tanks at his farm. his 7.3 powerjoke would run fine off the farm tanks, his 06 f 450 just had to replace the tanks , lines, injectors and i think the turbo all out of pocket. he brought me the ford tsb to read as i was amazed they wouldnt explain it better to people in advance.

 

Same here, one is a Citgo, other is independant. I see the exact opposite, the CItgo is usually 4-5 cents cheaper, but my mileage is off, not a huge amount, but enough I decided to start tracking.

Our 3rd station is insane ( BP Ammoco ), they are 32 cents higher, at 3.52 a stinking gallon!!!!!!!!!!

I would have to get a serious amount of fuel economy gain to go with that fuel.

I think I am going to start getting a bit more aggressive with blending in WMO.

 

Yup same price at the pump....Was in Sussex NJ and got fuel a few weeks ago at a Valero station that had both Auto diesel Island and a truck Island . The truck Island was self serve -first time I have seen that in NJ ,BUT the price was the same as the full service But they had the fast fill pumps.

 

I drove from Montana to Louisiana last Feb and noticed about 2 mpgs better with Shell fuel compared to all the rest. Just to verify I filled up at the same stations on the way back. Shell did the best going both ways.
Too bad there aren't any Shell stations in Montana...

quick question, off topic why can't you pump your own gas in NJ?
