Many recent posts question low sulfer fuels and resulting injector pump failures. The Chevron web site suggests that there is no concern. I remember back in 1981-82; the EPA "Suggested" that the auto makers use water based paint for their vehicles. We all can remember the later paint sheets comong off the hoods, roofs and fenders of the 1980's cars and trucks. The EPA is a collection of political hacks and cronies who are intent on "massaging" the political life of the current administration. The Flexible Corp. of Loudinville OH no longer exists; as well as the GM Bus division. Why? Because the Government bureaucrats had designed "Low Floor" buses which GM and Flex could not manufacture economically. Personally, I cannot believe even Chevron, which employs many lobbyists to curry favor with and kiss the butts of Government and State Hacks. If possible, "Doctor " your diesel fuel with 20 % Biodiesel to improve lubricity. Just my opinion. -Dave in OR

My trusty old Allis HD6B book says that one quart of SAE10 oil in 10 gallon of fuel will maintain the lubrication on pumps and injectors. I really like the 2 cycle oil trick! Going to check that out.

I live rural. There are MANY 80's Ford 6.9's runing around out here with a zillion miles. Being rural without easy access to such things as truck stops or parts stores, we use whats available locally. The preferred choice thats kept all those Fords built for the sulphur fuel- required engines runing- 2 stroke chainsaw oil. Add a dose of 2 stroke oil to the fill up. Same ammount you would use to mix in 2.5 gallons of gas for a chainsaw to 20 gallons of diesel. Can't say how much that is/they sell little cans around here just the right size to ad to 2.5 gallons of gas. MAKE SURE YOU USE THE BLUE STUFF..... We figure if it'll run in a chainsaw & not foul the plug, it'll be fine fer the injectors & so far no one has had a problem locally....

I have been running 2 stroke oil in all my road diesels, Ford 6.9 and VW 1600NA"s. I found the best deal is Wally*World they sell it for about $8 per gallon.

Second the motion on the additives. Ag diesel (with the dye) still has lubricity, but highway diesel's gotta have it added.

Hey Dave, the recent posts, some of which are mine, aren't based on government reports, or anything like that. Unlike many of the guys on here that farm or whatever and maybe do a little mechanic work on the side I make my living working on equipment so I'm out there every day seeing what's going on and talking to others that are doing the same thing. When I see problems with my customers machines, and see how backed up my local fuel shop has become since the new fuel really hit the pumps hard, it sorta drives home to me that there is indeed a problem. Personally I don't understand all the "science" behind any of it except that like a complete machine, a fuel pump has it's own moving parts that need good lubrication and if their not getting it the parts are gonna stick or at worst sieze up and stop all together. The sulfur provided some of that lubricatin and with it gone so are the lubricant qualities it provided. Besides the sticking, and again I don't understand the chemistry involved the lower sulfur content is also causing seals in contact with the fuel to leak. My brother in law just replaced a seal on his 7.3 that he was told they used to keep maybe one 1 of in stock, but now their going through them nearly as fast as they can order them. If that isn't enough for you in my own experience, I've been running the Stanadyne additive in my service truck. Withnit weighing in at just over 30,000 lbs all the time I've gained approx 1MPG since going to the additive. On a typical 60 gallon fillup that works out to an extra 60 miles I can drive before another fillup. At the going rate of $1.50 per mile the $6 spent for the additive nets me an extra $84 in profit to put toward upkeep on the truck as well as offsetting the rising cost of fuel. Any way you look at it you can't go wrong by running an additive...if for no other reason than to be safe now rather than sorry later.....

GOOD point.

You won't hurt the pump by adding in the additive, so why not be safe?
