In Reply to: Comments on using Prolong on an E34 ? posted by George on July 01, 1999 at 00:51:16:
As a matter of fact, I just used Prolong a week ago. I bought a kit that included engine treatment, trans. treatment and fuel treatment, as well as some WD-40 type cans. I have used them all and I experienced a notable gain in power and fuel economy. The packaging said that it was safe for all types of engines and transmissions. Hope this helps.
: Hi there, has anybody used Prolong or any other fuel additive on a E34? I have a '91 BMW 535, due for oil change pretty soon. Have used Prolong in the past wiht some semi-noticeable difference... is it OK on these types of engines? Thanks!
