I almost gave the car away for scrap. I am skeptical about products that make claims like this but I really did not want to throw this car away for scrap as the repair is more than the car is worth. The local “Pick & Pull” auto junk yard offered $500.00. If the car was in good running condition it would be worth about $3500.00. Ford Windstar has a known problem of warping heads and this was my problem. As a last ditch effort I purchased this product, followed the instructions to the letter and to my amazement, It worked and worked well. As of this review, I have put about 5000 miles on the engine and it’s holding up just fine. Can’t say how long it will last but this is much better than junking the car which is in great shape otherwise. Four stars just for being such a hassle to take engine parts off and on.

Worked as promised. It took a lot of flushing to get water running clear, taking hoses off etc. running car watering cans etc… I took out the wet spark plug (my gasket leak was air to water/radiator) and iddled the car without it, with the stuff in. It then took just as long to flush out after the drying out period. It worked a treat, car runs perfectly now. I may get another bottle as I have two peugeot 306′s and they are prone to gasket failures (lh spark plug areas)

Used on my Yanmar sailboat diesel engine. Like cars, the fuel injectors get dirty and the engine does not run as smoothly. This is a great thing to use twice a year, at least. Noticeable difference in engine output and smoothness. Final step in any sort of tune-up and in between.

  • 05228: Diesel Fuel Therapy® Diesel Injector Cleaner Plus, 1 Gal – Los Angeles, CA


This is a really good contact cleaner. I use this for light maintaince in computer and radio work. I recommend.


I cut it with water 1 part of oil to 30 parts of water to use it in a magnetic drill , it provides cooling and lubrication so the cutting head lasts long time


Works great. Will last about a year on the 2 gallon coolant system of my bandsaw.

The machine now gives clean cuts and stays cleaner (plus of using coolant).

Been using it for aprox a month the blade still looks like new and I’ve cut heavy steel and some aluminum. (I’m a fabricator)


Performs like it should. I have always had good luck with CRC products and this is no exception. I use it in my shop and it works well for all our needs. When something works well, I do not change. The old adage “if it is not broke, don’t fix it” applies here.
