Rated 5 out of 5 by from Flush it, flush it real good! 156,000 miles on my Ford. That's a LOT of oil changes. I flush in between each oil change. Nuff said.

Rated 5 out of 5 by from Great "Pre Oil Change" product I have been using Motor Medic flush for all my cars for years. I actually run the car(s) at idle for 15 to 20 minutes and then change the oil. It's great to get the insides of the engine free of "junk" and sludge, especially for high mileage vehicles.

Rated 5 out of 5 by from Excellent Product I have used Gunk Motor Flush since the 70's. Various motors and types, cars vans trucks and boats. Every motor has recovered from noisy, rough running and bad milage. My latest "Gunk Motor Flush" recovered a Mazda, CX-7, VVT actuator from making noise during the first 3 seconds after start up. Taking the vehicle to the dealer showed a $1,100-1,200.00 repair bill staring her in the face and a very complicated proceedure to make it all better. 5 minutes, an oil change and the cost of this product took the noise away, which by the way was nothing more than a dirty sludge build up around the VVT actuator. She is now having a noise free start up and increased mileage too boot! Great Product Too bad Dealers Don't want you to know about this product. I will continue to buy it long into my future.
