We all want too get fast results with auto-rx, the problem is that this may take sometime and miles. Many people have used cars that they have bought so the maintenance history may be unknown. Realistically a person who buys a new car and holds onto it for a few years and then sells it may not take car of th...

Yesterday at 75 hours I changed the oil again which had an ounce of a...

I juust added an oil cooler when I remoted my oil filter. I can monitor temp and pressure now. I run 196 if I set the electric fans for 200 water temp. I prefer to run 180-190 water temp. This drops oil temp down to 175-180. Any thoughts? I've done an ARx clean out and run 3oz maintenance dose. -- Edited by kab...

Please do not believe the hype about motor oil's that can clean. There is one commercial out about a particular motor oil that says it cleans 46% more sludge than the other leading motor oil. Motor Oil's do two things: 1) Lubricate parts 2) Cool parts When I got my 1983 Chevrolet El Camino back in 1985 w...

Didn't know if Edge fell under the group III catagory or not. I'm half way through the rinse phase and it's time to change the oil, scored some Edge cheap but thought I'd ask before using it. Thanks, John

I purchased a 1980 Toyota HJ45 with the 3.9L six cylinder H diesel. The previous owner told me the engine needed rebuilt because compression was 35% lower on one of the cylinders.

Most likely yes. Auto-Rx is a relatively slow, methodical cleaner that will dissolve sludge as you drive. As long as the oiling system is not fully plugged up, and the oil pump pick up screen is still open for oil flow. Auto-Rx can only work if oil is freely flowing. There is a complete application for sl...
