[Merritt Wikle, Auto Enthusiast & Chevron Lubricants Employee - 2000/10/20] The formulations of all manufacturers aftermarket products is very proprietary. So it is unlikely anyone knows Chevron or BG's formulations. Chevron sometimes tests/analyzes selected products a part of competitive analysis. I do know BG44K is a fine product. Further, Techron Concentrate is not just "4% active ingredient", with "filler" for the balance. [BTW filler in gas additives is typically some type of solvent.]

The active ingredient in Techron Concentrate is engineered and manufactured by Chevron. Though we do contract the actual bottling of the "juice" to others; it is Chevron that originally invented, made, and patented PEA (polyetheramine) fuel additive technology in the 80's.

In short, Techron Concentrate is the "original", and still unbeatable fuel system treatment.

In fact, the automakers use Chevron gasoline with Techron for EPA testing, even though we do not market gasolines in the Midwest (they haul from Louisville KY).

While I cannot comment on any specific Chevron Chemical customers I might know of (I'm not in Chevron Chemical group), Chevron Oronite Chemical Division sells very good PEA fuel system additives (not Techron Concentrate, though) to many well-known customers both as aftermarket chemicals, and for use in bulk gasolines. Typically these customers package and market these chemicals, or use them in bulk gasoline.
