Berryman1216 Oil Change Flush, 16-Ounce

I drained the oil on a kia engine added a quart of oil then put this in and ran car exactly 5 minutes. Then drained and put on new oil filter. It did clean the engine up a bit. Car ran much smoother getting gunk out. Car has 165000 miles on it. I did notice a difference

Does what I needed

Good product/ I just used 6-7 ounces combined with 6 oz seafoam in my engine that had 167k miles - did great

I normally recommend against engine flushes, especially if you don't know the maintenance history. Often an the sludge in an old beater is all that is sealing it. Flushing it can leave you with a leaking, oil smoking mess. In this case, I did know the history on a '07 Saturn Ion 3 with the 2.2. consistent 5k oil change with full synthetic since new. Approx 100k on the clock. I dumped the existing, and replaced it with the cheapest filter and dinosaur oil I could find. The flush replaced the last quart. Note the existing has 3k on it, and was still translucent. I let it idle for about 20min, then dumped it. There was indeed some color in the oil - similar to the oil I dumped, so it did something. But it is hard to tell how much. 4 stars as it did indeed scrub something inside, but I just don't know how anyone could ever know how much or how complete of a job it did. This was more of an experiment - I still am not a fan in general, and likely won't do it again.....

My vehicle has 173K miles on it and oil changes every 3000 miles town driving, full synthetic. The oil after using Berryman's didn't look any darker. So I believe the Engine was very clean to start with. What is just awful is People buying an expensive car and only changing the oil once a year. My good friend is a Toyota Mechanic and tells me of the many Toyota Engines that drink oil, all because their owner's follow the Toyota 10K mile OC intervals. Maybe driving all freeway one could get away with it. But most People drive lots of stop and go miles. He has lots of picture of the insides of the failed engines. If the Piston Rings get stuck with sludge and carbon. the rings can exert lots of pressure on the cylinder bores and permanently damage them. Oil is cheap, engines are not. He said to use caution if buying a Toyota product with around 100K miles as it may have only had 9 oil changes. Other manufacturers are also extending oil changes to 10K miles or more. Audi, VW, Toyota, Lexus to name a few.

my car has 200k used flush ,left in for 15min oil came out darker than dark really did a good cleaning .

I used this because my truck has 250000 miles on it and the oil pressure gauge went to nearly zero while pulling my boat. I knew the oil pressure switch has a fine mesh screen under it. I thought that sludge had stopped the switch from reading the oil pressure. I used this product per instructions and then changed the oil and filter. Once I fired the engine, the oil pressure was at 50 psi and settled at 40 psi after it got hot while driving.
