I just bought a 06' duramax lbz and I'm wanting to know what gas stations have creditable diesel. There's truck stops near my house like flying J and pilot, but also have sunoco, bp, speedway and shell.

I've had diesels for years and have filled up at just about every major brand of station. I've never had a fuel-related issue. I think it's safe to say any of the top-name fuel suppliers will have good fuel.

The secret is to keep an eye on your local stations and find out where all the local fleets fill up. Watch for ambulances, fire trucks, UPS trucks, etc. The rule is that the busier the station, the more frequently they get fresh fuel. You want to avoid old "wet" fuel as best you can.

Stations that are newer have modern tanks, and filters. Look for BP, Marathon (refined in Findlay by you), etc, and other stations on main thoroughfares.

Congrats on the new truck.

NOT THE MARATHON AT 13 and 71 in MANSFIELD!

Picked up a full load of Sh!t on the way up to the lake, boat US had to come tow my rig all the way home.

When I pulled the tank it had what appeared to be the fibers like you would find a fuel filter element made of, like paper. Seems like one of their filters let go, or had not been changed in a long time.

PS- Sorry I missed your call last night, I'll give you a buzz this evening.

that's the first place I hit that had diesel when I left wooster, you got to be chitting me. What luck

Anyway that's cool. Ill be home.

Don't be shy on changing your fuel filter. I do mine every 10k on my LBZ. As for stations I try to pick what I feel is the station that moves the most diesel fuel.

I wouldn't buy from wallymart! Two clogged filters last week. It's almost inevitable, you'll get some crappy fuel sooner/later, think about installing a spin-on fuel filter ahead of the factory one.

doesnt matter. All depends on if the places have good tanks or not. Biggest thing is empty your fuel water seperator monthly and change the filter twice a year and youll fine. That was one reason I got rid of the diesel, just finding a station that carried the stuff at times was a challenge.

A branded station does not necessarily indicate high volume. Truck stops are usually a good bet as are fleet fuel locations as mentioned.

Watch out at BP! While diesel handles are tradtionally green, BP feels the need to buck this tradtion and label one of their gas handles greeen. There have been many people that have pumped a load of gas at BP. (VERY BAD) I remind family/friends that use my truck of that too.

If you want trouble driving, get a lift pump. Your truck is old enough I am not sure you would get a full ROI of a pump/filter/separator like FASS or AirDog but Kennedy Diesel has a nice lift pump only.
Save wear on your CP3 (fuel pump) and possibly bring some new life to your old truck as the CP3 can start to get weak
Push marginal gelling fuel on through (I have NEVER had a gel issue)
Make fuel filter changes a breeze. No 100 pushes on the priming bulb, just turn the key and tighten the screw when fuel comes out.
The stock fuel system uses the CP3 to suck fuel (like though a straw) 20' from the tank up to the engine, through the filter, then pressurize it to 22k psi. There is actually negative pressure on the fuel line. A lift pump does all the work getting fuel to the CP3 and there is a positive 6 psi so all the CP3 does is pressurize to 22k.

If you are as anal in over changing your filter as other posters are, the full package will give a quicker ROI. The larger cartidge filters hold many times more debris, filter down to 2 micron where stock stops at 10 micron, much easier to change spearate, more effective water/air separator, cheaper than stock filter. I went 40k on my last filter set with no issue or drop in pressure, just thought after 3.5 years it was time, going into winter.

BTW, I buy my fuel when ever possible at a local farm CO-OP. The OWNER knows his fuel and buys only the best, low parafin he can find. They deliver to farm tanks and take every step possible to have good fuel because they want to minimize any issues with the farmers.

My last truck was an 06 LBZ. The only issues I ever had were when I got fuel from Speedway. Although, it was right about the time they were changing from low sulphur to ultra low sulphur fuel. I have bought a lot of diesel since then and no problems. I do avoid "low volume" appearing stations. I liked my LBZ a lot, my current '11 DMAX takes DEF (exhaust fluid) and that is a pain.. I posted about my fuel issues on here, if you feel like searching the forum.
