Put in Auto-RX about 600 miles ago in my 95 BMW 525i with 115,000 miles. Note the car uses no oil with no observable leaks,
M1 5w40 truck and suv oil already had 1,500 miles before I changed the filter and added Auto-RX.
I did a blotter test before the RX and at 600 miles. I noticed a slight increase in darkening on the blotter. I assume this is expected even without the RX. The car runs great. Seems stronger with slightley better fuel economy. However, it is cooler here in central KY and AC is used less. That always affects my car in a positive way.
Anyway, just my initial experience.
BTW, I have recomended it on the BMW forums. Interestingly, I get about a 50/50 comments about anything like this is "snake oil" and comments that they tried it and it worked great.I have also recommended they check Auto-RX out on Frank's web site and this forum.
