Seems some people were just jealous, no respect for the old timer. THere is no doubt on a grand scale that Auto-RX is the best additive ever made ! Not so much anti-wear like Slick 50 used to claim etc, but in general the best. I think that LC-20 will follow closely behind. The cleaning additives seem easier to guage, the anti-wear, people are looking for miracles, but thats because the makers claim miracles........ I think Auto-RX and LC-20 have proven enough, especially with Dyson comments on it. Good luck Frank, even though your product has already paid off...... We [censored] all day about oil companies, we have no one to talk to directly and scrutinize their product, there was one for Auto-RX and seems people [censored] him off.
