    • Works
This stuff plain works, no other way to explain it. I’ve seen it help get rid of stuck lifters and it get a ton of sludge out that you normally couldn’t with an oil change

    • Cleaner, smoother running engine!
This engine flush may be the most amazing product I've ever seen in my lengthy automotive career! I have now used it in everything from high performance V-8's to economy 4 cylinders; boat engines both inboard and outboard (4-stroke); and now even as regular maintenance for the zero-turn mowers in my lawn cutting service. The results are predictable and remarkable; smoother, quieter running engines with much cleaner oil throughout the length of the oil change. In the case of my 2004 GMC Sierra (225,000 miles) it transported my engine back to 2004 and running and performing as it did when new. To document what the effects were I changed my oil (2004 GMC) after using the engine flush and then re-changed the oil at 500 miles (still looking like it was just changed) again using Quick-Moly engine flush....... and the oil that I drained out was totally black. Keep in mind that the engine flush that went in is virtually clear. Seeing is believing!!! ... show more
