I recently saw this product link on another forum . It looks like possibly it might 2-3 esters and an additive package . Like many products we see that can be used for other purposes I just wonder how effective this Exxon product would be in a gasoline or diesel engine if used wisely . A look at the TAN tells me like the maker suggests a flush oil should be used but that wise with any engine cleaner .

I will obtain pricing and packaging sizes soon but I do beleive it comes in small pails for low cost .

However, for a poorly maintained engine there is Auto Rx a Lanolin ester.

Here is another bio type cleaner named Kleenz-It.

Wording at the website makes me want to try it at lower amounts in a nice and clean engine as a liquid filter .

No good for my type of driving

Drive the vehicle at normal speeds not to exceed 65 MPH

With a good Synth these products should not be necessary.
