1996 7.3l turbo should I be using any additives? If so which one is the best.

Stanadyne is the only ford approved fuel additive to my knowledge...lots of guys use it...I think its a pretty good product IMO.

I was using Stanadyne, then switched to John Deere (supposed to be the same stuff) and am now using Powerservice in the grey bottle. So far I have been happy with all three.

Just make sure that whatever brand you choose, it does not contain alcolhol. I also like Stanadyne (Performance formula). Cheers!

This is kind of personal preference. You don't have to use it.
I do as I feel the engine runs a little better with it.

You can use: Standyne, Power Service, Howell's, Lucas fuel injection treatment, STP diesel treatment, or Redline diesel fuel treatment.

I have used all of these and they all seemed to be similar.

Overall I use Power Service disel kleen the most as it is easily found locally. Next would be the Lucas which I like because it is for Diesel and gas fuels so I can treat the Suburban with it too.

I use Stanadyne religiously. 2 years ago, my truck started losing power, someone advised trying Stanadyne at the time and it perked it right back up.

A couple of times in a bind I've used Howes as it's available at most truck stops.

I used stanadyne for a while...was a little messy trying to transfer it to the tank from the 1 gal bottle.
I run bio now which lubricates and cleans everything nicely.

Ford says you don't need any and I have NEVER used any. 370k same fuel pump & all injectors. No problems at all that an additive would have helped.

my diesel mechanic says that over the last 7 years that diesel fuel has had the sulfur content lowered several times for clean air standards and that causes less lubrication and more wear on the engine, so an additive is needed.
Not sure how true this is, just thought I would throw this out and see what you think.

Ford has thier own fuel addative out now. Its even listed in the new truck manuals for 06.

PM17A - costs around 6 - 7 bucks at the dealer and treats 125 gallons

1st ingredient out of 3 is kerosene...so basically, its a 7 dollar bottle of kerosene... /ubbthreads/images/graemlins/shrug.gif

so we should just add some kerosene to each tank to get back the lubricity the feds are taking out of the fuel?

No...the kerosene is just a convenient carrier for the chemicals that make the additive do it's work.

I'd like to know what's in Stanadyne, man that stuff stinks!

For anyone that's going out to get a jug for the first time, don't keep it in the cab of your truck, if it ever spilled, it would be months before you would get the smell out.

actually just dump in a couple cups or so of veggie oil that will give you some lube in the diesel.

Where do you guys come up with these things anyway? That's worse than the idea of adding ATF. Save the veggie oil for fries and your ATF for your tranny and be happy you are using it for it's intended purpose.

1) Diesel additives are of questionable benefit but won't do harm as long as they don't contain alcohol. They "may" increase performance, it's doubtful they clean injectors and they do increase lubricity which is of dubvious value on a PSD. What I can guarantee they will do is make your exhaust smell like crap. Additives will also probably increase engine clatter and noise.

2) Whoever said their mechanic said that additives must be used needs a new mechanic. PSD's, from their beginning, were designed to run on low sulphur diesel, even the CA formulation. Lubricity for the older Ford IDI diesels was a serious problem because the low sulphur diesel caused o ring failures on injectors and injector pumps. That problem was designed out with the PSD.

3) They will prevent gelling if used at the highest concentration recommended but, in areas that have the problem there is a conversion to Winter fuel anyway so it's probably not needed.

4) They increase the cost per gallon fuel cost and won't give enough of an increase in economy or performance (probably no increase) to ever pay for it's use, So why bother?

Most people that just HAD to put additives in their gas engines currently get a warn fuzzy by spending extra money to add it to their diesel fuel. Same with engine oil additives.

You aren't serious are you? What is wrong with vegetable oil?

If it's properly processed into biodiesel go for it. Just dumping veggie oil in your tank is laughable. It has no useful purpose at all.

Actually bud, veggie oil will lubricate, by itself. And it won't hurt a thing as long as its not used.
