Well, I've been poring over the long thread that is the basic discussion here on the question of using 2C oil as a fuel add in cars. I've been trying it in the Camry for a tad over a week now, and I'm very favorably impressed. It's not often that you try some additive or another, and really see, feel, and hear results, but I can in this case. Starts are smoother (and this car starts a lot in urban driving), running is too, and though I have yet to nail it down with calculations, it appears I'm getting about 2 mpg better than I was before adding 2C.
But this leaves me wondering -- which one to choose. For now, I'm using this:
Pennzoil seems to have at least two 2C products, a syn and a non-syn. Note the language on the back panel, to the effect that it uses ester base oils. This drew my attention, as I theorized that the polar nature of many esters would likely keep it more strongly attracted to metal than might be the case with other base oils. Unfortunately, it is also about 2.5x as expensive as the PZ product that's not synthetic. Both appear to be TC-W3. Anyway, there's quite an array of 2c oils out there (not as many as 4c it would seem), certainly enough to keep a consumer confused.
So, let the commentary and recommendations begin.
