Engine oil in fuel??

Not sure but I hear a lot about supposedly algae thats black and slimy to the touch that I hear a lot of people complain about mostly from Pilot fuel but have never seen or gotten any to speak of. Heard a ton of people on KR's Sirius show talk about it. Also talks a lot of asphaltines (not sure what they are) that a lot of people are having trouble with in their fuel. I know there are places that you can send fuel samples and they can tell you what it is, just like you send oil samples. Not sure if any of that is your problem though, just my .02.

 

might just need some fuel conditioner--we used to get it jet A --a truck at that age probabely has had a lot of crappy fuel run thru it--just treat it and it will be ok

 

get some molycoat fuel treatment, this stuff will clean the ha3ll out of your fuel system, be sure you have several fuel filters with you.
I wasn't' having any problems but it was on sale one day and I bought a bottle to give a try,all I can say is WOW, I had just done a service a few days before I put it in the tank and the filter couldn't have had more than 2500 miles on them when all of a sudden, going down the highway and it starts spitting and a sputtering, I limped into a truck stop and figured out that the fuel filter was clogged, I cut it apart and couldn't believe how packed it was with crud,mostly algae, i had to change the filters three more time before all the crap was out of my system and the truck runs much better, with better mileage [about a half a mile more per gallon].
I now put a bottle in about every 10000 miles and haven't seen a lot of algae since I started this
