Is Prolong oil treatment a good idea?
I have a 2.0T FSI. 2006 2.0T Audi A3 non-quattro manual transmission. 280,000 miles.
Prolong made my lawn mowers last forever but I've heard that Audi said "Prolong is not a good idea" -- but that's so often their automatic answer
Anybody have experience with this supposedly super-slick oil additive?
