Guys---have always run Standyne but a friend of mine tried this in his Duramax and swore better mileage and a quieter engine and of course I said “bull hockey” show me so next time we went to the ranch I had to agree it was noticeably quieter. Could not verify the mileage part but I have run 3 tanks now and my engine does run quiter and I did pick up about .75 mpg in fact these last 3 tanks have given me the best mileage I have ever gotten.. Anyone try this stuff yet---seems too good to be true hope it is not hurting anything.[duhhh]

Check Gunk MSDS between the sulphur substitute and their fuel injector cleaner. Same stuff and heavy on the solvent.

If you want to add sulphur back to your fuel just dump in some non detergent motor oil.

Sounds like a sales gimmick since the amount of sulfur in fuel has no effect on an engine's performance.
It's the process that removes the sulfur that causes the problems in that it also reduces the fuel's lube qualities.

I am very familiar with the refining process and the relationship between the removal of sulfur and the corresponding effect it has on fuel lubricity. This product for whatever reason has worked better than any of the Standyne or Lucas products I have tried in this vehicle over the years. Can’t figure it out because I cannot find any testing data on it yet..

It looks like the main ingredient in this additive is Aliphatic Hydrocarbon Solvent.

What brand is a non-detergent motor oil?

Look for straight weight motor oils with a SAE 'SA' rating. I seen these oils in 20, 30, and 40w.

Walmart usually has this type of oil in stock.

Ah I see... I've been contemplating running waste motor oil after seeing that thread but I'm still kinda hesitant.

What weight of non-detergent should you use, and how much per tankful?

I would not run any lubricant that was not designed to be burned. Engine oil will burn, but no totally nor cleanly. If you want oil, run 2 cycle... but that's been tested and is not the lubricity additive we all thought it might be (nor is engine oil).
As stated, It's not the sulfur, it's the aeromatics that get removed during the desulfurization that has reduced lubricity and mileage.
Don't know aliphatic solvent or if it adds areomatics...but doubt it?

Been running this stuff about 5k and it does work! MPG has picked a little over .6 and the engine is running quieter than it did before. This is the best additive that I have used over the years. Wish someone would conduct some testing in the lab on it.

Did some research and checked their MSDS Sheet. Product is primarily Aliphatic Solvents .... which are Saturated Hydrocarbon and, as such, contain (add) no aeromatics.
So don't see how the product increases lubricity, but I hear you are happy with it..... so Good Luck!

thanx. some companies make it kinda hard to find out what's actually in their additives- that would concern me if i was using their product.

It's spelled Aromatics. Sorry about being picky but I work in an aromatics chemical plant.[roll]

It's spelled Aromatics.
Thanks, I DID know that...guess my flying background got in the way of my spelling!! [laugh]

Not to beat a dead horse but my father added this to his truck, and has noticed an increase in mileage. Can't comment on how or why, but it did?
