My friend Chris is driving his 1991 F350 across country in a move from Oregon to Vermont. He's towing a Subaru on a flatbed trailer as well.

He's in Colorado right now west of Denver and is having some problems with his wvo system and asked if I could help him gather some info. I'm a biodiesel noodler and am not much help to him, so I thought I'd post a couple questions over here on the wvo side.

He has a 70-gallon wvo tank in the bed of the truck. He says he's seeing some rusty colored gunk (algae?) on the insides of the tank. Says he has about 60 gallons of wvo in the tank right now.

This reddish stuff is clogging up his filters. He's had to change a couple between Idaho and Colorado.

He's still able to run fine on diesel but would obviously prefer to run wvo.

He said the oil had sat for about a month before he put it into the tank. Was filtered to 5 microns on the way in.

The tank is heated and he says temps in the tank, as gauged by his thermometer, are running 150 to 170F.

He's considering this strategy and wondered if anyone had ideas, suggestions, recommendations: He's wondering if it would help to add something like Diesel Kleen to the wvo tank, let it slosh around while driving and then drain out the tank. (He has a cleanout valve in the bottom of the tank.) Next step would be to refill the tank with the other barrel of oil he has.

If any of you have any insight or suggestions I'll relay them to Chris by cell phone. They'd be much appreciated - he's just the sort of fellow who'd be the first to pull over to help someone.

All the best,

Eric

I had a problem that sounds similar. Maybe something here will be helpful.

How about he add in a few cheap inline prefilters to catch this larger stuff. Have him buy a good handfull cause he will have to change it several times)!!!! Also tell him to find a boat place. (boaters world?) They more often carry the algaecide then say Autozone. MAYBEE a big rig service place might have some? Once he gets it then mix it in the WVO according to the lable.

As to why it is there.... not sure he can get that figured out while on the road. Maybe his preperation filter system was not up to snuff after all etc.
