slc, no viable company is going to disclose its full formula for obvious reasons.
As with any product I have independently tested or worked for as a consultant in testing, I cannot confirm nor deny the proprietary constituents of the formula, if I know it.
I can say that bruce381 provides a cogent point.
I can say that engine makers will attempt to "channel" the customer to their pet marketing driven products by throwing out data that compels the owner to buy the "approved" ( officially or unofficially) product.
There are many fine fuel add products that have a alcohol component and cause no harm, there are products that use none and they are the ones that Ford for whatever reason wants you to use. As in motor oil the final formulation and performance in the real world is the key!
I agree with Ford/Navistar, do not use an alcohol fuel add in their injection systems.
However, their recommendation, from what I know of this industry is motivated by marketing reasons, not actual worries about the formulations. No viable diesel fuel add maker recommends using harmful levels of any chemical as an add in the fuel.
Having said all that I recommend FP60 be used in every diesel customers fuel over any other you may be familiar with. If a fuel add caused problems with the fuel or oil side of the diesel engine I would see it in 30 year or work. FP60 has been in continous use for at least 50 years.
However, I do indeed see problems with many popular NAME brand diesel fuel additives that contain many chemicals including alcohol and those that contain no alcohol component.
I reserve the proprietary right to disclose those fuel additives to MY customers through the intellectual property of specific oil analysis results for their engine using said additive. My goal is not to sell an additive but get the best performance for the dollar for my analysis customers !
Hows that for tip toeing so I can still get the next job !
