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.
