Would not putting in a can of Chevron Techlorine a tank or two before
an oil change have the same effect? I run on Chevron Supreme, and 4
times a year put in Chevron's wonder additive. The van runs like a
top. It is important to do an oil change after a burning these
cleaners as the deposits end up in the oil. Just my 0.02 worth.
