Bio-Diesel Contamination?

Hello All,

I filled up the fuel tank in June and then didn't start the engine until we did a short 5 hour drive time trip last week. The engine ran great, lots of power. We are going on another trip tomorrow so I was checking fluids and decided to drain the water separator fuel filter. The attached picture is what came out the bottom of the filter drain. It looks like coffee and like stuff "floating" in the fuel.

I immediately took a picture and went over to a local heavy truck centre to show them. The service department said that it looks like bio-diesel contamination and that it shouldn't affect anything. They said to just change the filters more often. Both filters only has about 6 hours of use on it. I do use a lubricity additive that says it prevents bio-diesel contamination.

I drained some fuel out of the other filter and it look normal.

So do any of you agree or disagree with what the service department told me?

Yes ! Change the Filters- Apparently your MH sits for long periods of time between usage - Get some Diesel Kleen and use all the time.

There are no water separator fuel filters in stock at any of the local truck centers. However there is at our destination city which is about a 5 hour drive. Am I even going to make it there without the filters clogging up and stranding us on the side of the highway?

I think you'll be fine, but change the filters soon.

I agree with the others, change the filters frequently. If it were me I'd burn through that tank of fuel and try to find a better source going forward. I have worked around Diesel engines my whole career and I can tell you bio fuel is a challenge. While working at Cummins (15 years) we wouldn't approve of bio any greater that B20 for a long time.

Although I know of one large class 8 truck fleet that has successfully using B80 for several years. The real secret is burn the fuel before the bio has an opportunity to go rancid.

Bio diesel will clean tank walls and fuel lines so it generates that stuff. If you drain the water separator do you also get some black flakes? It's not organic like "algae" as they call it.

No black flakes that I can see but it sure doesn't look good.

Thank you all for your replies. I'm definitely going to change the filters and find a new fuel source. I have been using a Husky Truck Stop. There is nothing on the pumps indicating a bio-diesel blend or numbering. I guess I better change out my aqua-hot filter as well. I just put a new one of those on in the spring.

I thought by law they have to post the percentage. Probably varies state by state.

I have a 01 Dynasty that sat for awhile before I got it. Recently I was low on fuel and in a remote area and I put in 30% bio. I called Cummins and they said it would be fine for that fill up. I only put in about 1/2 tank.
Since then it's difficult to find fuel that doesn't have 5-10% bio. I've heard 5% may be preferred but I didn't hear that from Cummins

Ever since I put the bio in the fuel has been darker. Runs fine and I change my filters every 6 mos and cut open the primary. I used a biobar kit to see if it was organic (like so called algae) and it was not. I pulled some fuel off the bottom of the tank and it looked the same with no large buildup of sludge apparent.

I'd run it and change your filters and maybe cut open the primary to see how bad it is. . I try to avoid bio over 5%.

I did lose my CAPS pump around this same time but no way of knowing if that was related.

I'd love to put a filter restriction gauge in line.

To me B20 is already "contaminated" I won't and haven't used it.

I Always Fuel up at Flying J- They advertise B15 Bio mix at the pump- I'm ok with that but I add a qt of Diesel Kleen at every fill-up. It helps !
Keep your Fuel Clean and as I mentioned before - Fuel sitting in the tank for months on end will absolutely create problems.
