Keeps Old Cars Rolling

I used Auto-RX in a +300K mile 1979 Chevrolet Malibu 305 V8 that was leaking one quart per gas fillup past the rear crank seal. I noticed an idle improvement shortly after starting the treatment; de-sludged piston rings. By the end of the treatment phase, the remaining minor drips consist of pink ATP only! I recently let my brother know about my good experience, but before I could name drop, he said “Auto-RX.” He used it on his 1968 Chevrolet Corvair for similar reasons and got good results, too. Your great product helps keep old cars rolling and helps users postpone expensive engine overhauls. I’m re-ordering more today for ongoing maintenance. Thanks very much!
