I hate how BP uses a green nozzle for 87 octane. Friday night I rolled into a BP off I-40, looking for hte diesel pumps, I saw 2 large landscaping trucks at the pumps, figured diesel must be at those pumps. So i spotted the green nozzle, then some dude came up started chatting about my cool 'rockcrawler'. At that point I wasnt quite paying attention, slid my credit card, started pumping with the green nozzle. I had this weird feeling, then it finally hit me. My stomach turned, I felt so stupid, luckily I was only into it for 3 gallons, on top of my 1/4 tank of diesel. I had to ask the clerk where the diesel was, it was hidden out back, so i rolled to the pump and filled it as far as I could. I noticed no ill effects from runing 3gal gas/~31 gal diesel in my~34gal tank. It made it to about 30 more miles to Vale, then the next day Vale--Greensboro.

Should I just keep running it as is? The most prudent thing would be to drain the tank, but don't think that will be necessary. Keep it full of diesel, so it continues to dilute to nothing, or run it down to almost empty, then refill with fresh diesel?
 
Wow dude lucky only the 3 gallons. If your not going to drain the tank which you already know is the right thing to do. Then I would burn 1/4 tank then refill and so on so you should be at the pump every day.
 
Dilute and run some seafoam or diesel addtive is what I would do. That's about a 10% mix at worse case. Keep topping off for a few days...
 
Tony, when I had the CTD & was cruising the boards regularly, this was a fairly common occurrence... mainly from family/friends borrowing them. :tongue:

I recall one post that linked official Cummins documentation (maybe the owners manual?) showing that a certain % of gasoline in the diesel was fine... IOW, Cummins had already tested it (guessing it was bound to happen?) and set the "approved" ratio.
 
We had a guy when I worked for Cat that would feed his service truck a "hot lunch". This was filling it half up with gas to try and blow the motor so he could get another truck. Funny thing is his truck with a detroit motor kept going for quit a while. It finally went a few weeks later and the just resleved the cylinder wall that it burnt. Kinda funny story.
 
just dilute it out, top it off every couple of days. once you have put about 3/4 of a tank of new diesil in it change out the filter and you will be good to go
 
i always said it takes a special kind of stupid to do something like that. then one day i pulled in to get fuel and noticed all the pumps were bagged off except for the green handled pumps and said to myself,good thing i'm getting fuel and not gas because their out of gas. 15 gallons later i felt a special kind of stupid:confused:
 
My buddy did the same thing at a BP. As soon as he told me what he did, I said it had to be at a BP. He said yes, how did you know. I told him I had one of those nozzles in my truck and at the last second just happen to notice it. He was trying to get to the inlaws reunion, wife talking, kid crying, pulls into the BP on E, glad to get out of the truck, grabs the "green" nozzle and sets the latch and takes a breather. Truck FULL, grabs receipt, jumps in truck starts it and gets 25' till the truck is missing, white smoke pouring out of the exhaust. Shuts it off and is thinking wtf? Resarts it and same thing. Shuts it off. THEN it hits him like and hammer on a anvil. He hesitates to go look but he does...36gallons of gas. Rides a rollback to the shop. We pump out gas, have to change both filters, fill with diesel, add additives and back on the road. He will never do it again and I must say after helping him, I will not either.
 
Thats what you all get from buying from BP. Just kiddin. I about filled my 08 wrangler up with diesel on the way back from the beach last year. I felt dumb when the guy behind me in the diesel truck asked if the jeep was diesel. I then relized I was trying to fill up my truck in my mind. Thank goodness he asked before I started pumping.
 
Tony, Like stated if it were me I would run it through and dilute it a couple times.


Wifes friend put diesel in her Honda Van, Lucky she noticed and it had it towed. It also was at a BP. She was the maid of honor at a wedding that we attended. Needless to say she was late getting there. :lol:
 
bacon grease makes it even better
 
Years ago, when I drove a milk truck, we would put a couple gallons of gas in the tank and then top off with diesel. Boss told us too to keep fuel from gelling at around zero degree's. Never had an issue, but that was 2 gallons into a 50 gallon tank.
I think youll be fine. If you are worried about it, pump the fuel into clean containers, and add back 5 gallons at a time till you have it all used up.
