Fuel treatment ?

I like Lucas, at double the reco'd minimum amount. I've had no injector failure since starting use. It does not seem to produce the advertised fuel economy increase till this level of use. My engine is also an older one. I slip a bit of feed grade powdered sulphur in. About a level tablespoon per 50 gal.

My opinion would be go with the Schaeffers Diesel Treat. It has done wonders in my ride. Not only in the fuel economy, but gelling, and just all around performance. Howe's, Lucas, and Powerserv are all decent, but you really have to treat the heck out of the fuel to make a difference.

 

the only time I have ever seen the advertised fuel mileage increase is in a MBN cat bridge motor. I could pick up .5 mpg with lucas in that truck. unfortunatly it was still misserable

 

My Cat wasn't that terrible. Had 2000 mod. 550, egg-footing it produced up to 6.5 with a favorable wind. Like I said tho I was using a quart per 50 instead of a quart per 100 gal fuel. Reason I like the Lucas is the lubricity. Get some on fingers it takes much more washing to remove than any other additive I've tried. Just my own un-scientific observation. The addition of sulphur probably helped me some too.

Another vote for Schaeffers! Ditto on what pullingtrucker said. It's the best that I've found, so far.

 

Since you are worried about the fuel staying in the tank so long, try not to have it full. Let it get used down. Go to a farm store, like Deere and look for the alga treatments. This will keep the growth down. The other fuel treatments are good as well, because the fuel might have a condensation buildup problem.

We have to watch the amount of fuel kept on the tanker at the fire house. It has a 150 gallon tank and it will hardly use that in a year.
