806 man Posted September 24, 2022 Share Posted September 24, 2022 Been fighting this for a year. Running Cat 3406E in 4 trucks. Fleet-gard Filters last 1700 -2000 miles. Local shop guy says problem is the fuel has less sulfur (EPA) so an addictive is added for lubrication this additive is getting cooked in the head and creating fine black particles which plug up the filter ( we have opened filters and found this ) the guy says the cure is don't shut off engine till it has cooled more so the fuel won't be cooked in the head which we have been doing by leaving trucks running when fueling up each day. I have 2 fuel tanks a 15,000 for off road (no issues) and 6,000 on road which is where my issue is. Any knowledge of this issue or suggestions.

jass1660 Posted September 24, 2022 Share Posted September 24, 2022 Sounds like you need the fuel additive from cummins that treats asphaltines, they are created when fuel gets too hot. 1 Quote Link to comment Share on other sites More sharing options...
td9inidaho Posted September 24, 2022 Share Posted September 24, 2022 Kind of odd that your off road trucks or equipment isn't getting as hot as your on road trucks. My understanding is it's the same fuel, just die added. Are they the same distributors? Possibly different additives in the fuels you are getting if from different distributors. Be curious to see how this ends up Mark Quote Link to comment Share on other sites More sharing options...

Do you have more info? Last Feb. my jobber added Valvtect to the loads never saw much difference. He did say I wasn't the only one with this issue.

jass1660 Posted September 24, 2022 Share Posted September 24, 2022 I guess check with a Cummins shop and see if they carry it or call Pittsburgh Power in Pennsylvania and talk to Bruce or Pete about it. 1 Quote Link to comment Share on other sites More sharing options...

I don’t think the trucks have fuel coolers Quote Link to comment Share on other sites More sharing options...
ihrondiesel Posted September 24, 2022 Share Posted September 24, 2022 Algae in your storage tank will cause the same issues, the filters are black but usually sort of slimy. Maybe you have eliminated that possibility already. 4 Quote Link to comment Share on other sites More sharing options...
Diesel Doctor Posted September 25, 2022 Share Posted September 25, 2022 Wouldn't it be far easier to get rid of ultra low sulfur fuel. All the issues are costing the consumer WAY to much. 1 Quote Link to comment Share on other sites More sharing options...

If there were so many issues the online forums like this one, facebook, yt, and others would be absolutely CLOGGED with complaints for the last 12 years. Dead trucks would be littering the roadsides, so many the tow companies wouldn't be able to keep up, especially since their trucks died too. You hardly ever see anything in general, let alone anything that would be attributed to ULSD. You can't tell me all these people are suffering in silence in this day and age.

Diesel Doctor Posted September 26, 2022 Share Posted September 26, 2022 When I see a ball of rust inside a diesel pump, due to the fuel, that causes an issue with me. It ate away the timing mark on the governor weight retainer of the last pump I worked on. It seized the pumping plungers on a pump that was overhauled less than six months ago. It does not need to be as bad as Matt says to be an issue. It is costing diesel owners a great deal of money now. 1 Quote Link to comment Share on other sites More sharing options...

Almost all of them said they would never have another gas pickup again. Now, many are saying they are done with diesel pickups due to high costs and reliability problems. I know it’s not all ULSD problems, but it’s one of many. 1 Quote Link to comment Share on other sites More sharing options...

Yep. I went to a Cummins training class and they said its inside the injectors. Engine manufacturers have drastically increased the injection pressures to make the mist finer for better combustion to comply with emissions. This extreme pressure and heat causes a chemical reaction resulting in asphaltines. The small amount of fuel that goes back into the return line on the injectors carries the asphaltines back to the tank. 1 Quote Link to comment Share on other sites More sharing options...

Well I haven't left any along the road, i try to proactive and change filters when 2500 miles. i see a few making 4500 miles so maybe things are starting to turn.

I know it’s not all ULSD problems, but it’s one of many. That be my case running diesel Pu since 1993. On my 5th and last one. I think the engines are ok it's the kind of use I do is what creates the problems. when I pass one down pu gets shorter trips. Shop to most fields are no more then a 8 mile drive so never get worked or hot much. Quote Link to comment Share on other sites More sharing options...

I have a filter head which uses 2-10 micron Cim Tek filters which we change once or twice year, once the fuel is in the truck the problems start. 1 Quote Link to comment Share on other sites More sharing options...

All the issues are costing the consumer WAY to much. We have spent probably around 3X the money and time for maintenance along with increased prevention costs from more fuel additives since ULSD has shown up here. Done way more injection pumps since the lubrication is almost nill compared to with sulfur. We along with everyone else farming in the area have also had to add sulfur as a source of fertilizer since the change Quote Link to comment Share on other sites More sharing options...

JaredT Posted October 6, 2022 Share Posted October 6, 2022 Same mechanic also says to put automatic trans fluid in your fuel periodically to add lubrication to the ulsf deisel fuel. He doesnt have near the trouble with injectors in Duramax as most other locals do. I dont know if it help, but he has had good results.

Don’t do that in any emissions engine with dpf or you will pay big time. Quote Link to comment Share on other sites More sharing options...
