Diesel Fuel

Anyone have suggestions, or tips on getting diesel fuel? I have a few locations that sell diesel, including a Kroger gas stop and shell station, but I wanted to make sure I was fully informed before just going to one down the street.

Thanks!

Hi, I don't know if this is the right location for this question, so feel free to (re)move from this thread if not.

First off, this is my first Jeep/ off road capable vehicle and I am excited to go explore more. In the process, I am looking for some better off road tires than the Lattitudes that are stock on the DGC, and I came across a post about using the 2013-up Rubicon 17" wheels on a GC.

Now I know that the '14 DGC has the Heavy Duty (HD) brakes, but over the last few days, I have read conflicting stories about people being able to use the rubicon setup with minor adaptations. Another option I see a lot is the use of spacers, but I am a little concerned that the "aero" mode of the Quadra Lift Air Suspension may make the wheels rub.

My question is, does any DGC owner out here have first hand experience with running these particular wheels?

As a longtime diesel vehicle owner, I recommend only buying diesel from truck stops or gas stations that have high volume diesel sales. Reason being the less time diesel sits in the underground tanks, the less likely hood of water and other containments to form in the fuel.

Anyone putting in Power Service w/Cetane booster when filling up? Should boost MPG. Company says "it's safe for the new diesels" Used it in my 06' Ram 5.9L Cummins mixed with Mystery Oil. Blew lots of black smoke.

Most people recommend going to a busy station since they are more likely to have fresh diesel. Algae can grow in diesel fuel although I' m not sure how long it has to sit before that happens.

When I'm out of town, I go to places near the freeways that are likely to be used by RVs.

Have been running it in mine for the last month - haven't seen any gains per say, but with the rapid temperature flux its hard to gauge.

I have had many diesel cars and trucks over the 50+ years I've driven. I have tried numerous diesel additives and have come to the conclusion, additives do not provide any measurable difference in mileage or performance. Does provide quieter running engine in some diesel engines. Some I've owned: Ford power stroke, v.w. (several), Peugeot, Mercedes, 2006 Jeep Libby.

Fuel: great point mentioned above to picking up at truck stops. I have had a few diesels and my wife currently drives the ecodiesel while I drive my duramax. Pay the extra couple cents per gallon and make a difference.

Additive: I find the best thing is Amsoil additive. I put injector cleaner and cetain boost every third fill up. The cetain boost will give you a cleaner and more through burn and the injector cleaner keeps those expensive injectors working at peak performance. I would use it more frequently if I did a lot of city driving (every other fill up).

DEF: no need to pick up your DEF fluid from MOPAR. Blue Def works great. Wal-Mart sells it and so do a lot of local/national truck stops. Fill up at a diesel pump too if your truck stop has one. It's WAAAYYY cheaper.

Oil Changes on the VM motor:
Change it before it gets to 20%. I do 30% then I change her oil. Remember LOW SULFER EURO oil is the ticket. Filters are costly but do that with it of course. We have almost 18,000 mi on our jeep so we have done this a couple times. If you go the dealer route do your homework. 3 jeep dealers around here and 1 has done a jeep oil change (diesel) and still messed it up.


Fuel Filter: extremely important.
90% of fuel filters go by mileage. I would recommend changing the FF on these every 20k/mi

This is a labor of love and not a cheap one but if you do it right your diesel will last a whole (200k plus)

My brother ordered a 2015 Diesel from the TX group buy. He just picked up his jeep on Friday evening and then drove it from TX to WA. He drove 2219 miles at 80+ MPH and averaged 27.9miles/gal. I'd say that's good considering the speed and the elevation climbs he made from TX to CO, and MT.
