Last week I put some Auto-RX in a 1997 Ford 7.5L V8 fleet vehicle that had been neglected. It saw yearly oil changes with bulk 15w40 and Luberfiner filters prior to last week. The inside of the valve cover looked BAD and the dipstick had a brown glaze to it. Today after about 500 miles on the ARX there is a slight, yet marked, amount of the glaze gone off the dipstick and the engine sounds and feels better at idle. Previous to the ARX being added I believe there was a stuck lifter that would make noise after high RPM runs on the highway. No more of this noise as of today.
ALso the engine would only run on 93 octane without severe knocking even after a full tune up. I put a can of BG44k in the gas and it now runs on 89 octane without knocking. This was never possible before.
