great point/question.....i've just been reading that the Techron is stronger/better.
Actually, I use both Lucas and Techron, I think they both are products that in fact do what they say they will do. I feel they work well in my vehicles, in any case.
FWIW, I tend to use the Lucas more during the warmer weather, it seems to be a little thicker in consistency when it's cold. The Techron, on the other hand, is always the same liquid form, even when cold. Just my preference.
