My sons '95 Accord several years ago popped the radiator and subsequently overheated briefly.It has had an oil-burning issue, generally 2-3 quarts per a 5,000mi. OCI. At 250,000mi. I changed the oil along with a dose of Auto RX.
After roughly 1,200mi. he calls me and asked what happened to his car, all of the sudden it has much improved power, noticeable to him. Unfortunately I wasn't able to compression test at the time of the oil change for proof of increased compression, but for him to notice speaks for itself as he isn't mechanically inclined.
Today I ordered more Auto RX for a couple of older engines to see if more ring-pack cleaning can be done. After the order I was informed that they have a new product available, Auto RX Plus, its supposed to do everything that the previous formula does better. At this point I have everything to gain after the preliminary Honda results.
On a side note, the Honda was bought used by me in '07 with roughly 150,000mi., and OC's have been done at 5,000mi. intervals. I haven't had the valve cover off, but looking into the fill hole what can be seen of the valvetrain looks clean, so my reason for trying the Auto RX wasn't sludge, but cleaning the ring-packs.
