Works great, do the double drain for best results
My 06 Altima (185k miles) had been burning massive amounts of oil (like 4 quarts every 800 miles) due to a leaking PCV valve hose that took forever for me to narrow down (months). So after getting that under control I figured I needed to decontaminate the poor engine. When using this I idled my car to operating temp (about 8 minutes). Poured the bottle in, idled it for another 15 minutes. Drained the oil (black and thick). Put the plug back in, poured about 2.5qts of new oil in. Idled it for 10 minutes. Drained that (black but much thinner). Took the old filter off. Let both areas drain for 10 minutes. Put the plug back in, put the new filter on and filled with the 4.6qts of new oil my car calls for. Ran for a few minutes (like 2 with a few revs) and then let sit for 10 mins before checking the level. When I checked my dipstick it was so clean I thought I had a leak because I couldn't see it on any of the crosshatch. I ended up having to go by touch to get the reading. This stuff is amazing.

Excellent. Better than bran!!!
Excellent product. I use total synthetic oil and this product gave my engine an enema. Cleaned it out better than bran. I use it before all oil and filter changes.

Gets the sludge out
I used it on a 2017 Nissan Pathfinder, and it did get "most" of the sludge out. Unfortunately, the engine was already gone. The stuff works!

Seems to have helped
Bought a used 2020 Jeep Sahara 2 liter turbo charged with 80k miles from a dealership. Dealership had just changed oil the day of purchase. Drove it home 30 miles down interstate and another 20 back roads, it ticked and tapped allot at idle and the dip stick was varnished. I added the flush, let it idle for 10 minutes and drained it. The new oil from the dealership drained out jet black, no light could pass thru it. I changed the oil with Walmart oil and a cheap oil filter and let it idle for 5 minutes to clean out all the engine flush, it drained out clean and clear. I refilled it with Pennzoil Platinum High Mileage oil and a Fram Ultra Synthetic oil filter. It's been a week and the engine is noticeably quieter and smoother since using this product. If nothing else it cleaned allot of carbon from inside of my engine.

Product worked
I needed to clean the carbon buildup on the pistons and valves of a 2016 VW Tiguan. 2.0.. The product did not disappoint. I gained more compression on cylinders that were lacking compression. I did a before pressure test and after per cylinder. Happy with results.

HOLY CRAP!!!!
So my 2005 Durango has a 5.7 and I put on 253,000 miles on it before it blew a head gasket. Since it was summer, iI decided I'd tackle it myself. The upper end was so full of gunk, I can't believe I hadn't had serious issues. Anyway, I apparently dropped some pieces of crud down the oil channels, 'cuz after putting it all back together, I got alarms for low oil pressure. Figuring I'd try anything else before replacing the oil pump, i gave this stuff a try. WOW!!!! Not only did the oil pressure return, the engine runs SO much smoother! I had forgotten how smooth it ran when it was new. The caveat is that apparently the gunk was the only thing keeping some areas from leaking - as it lost oil at a startling rate. 1 bottle of the Liqui Oil Saver though, and within a week the oil leaks completely stopped.

Engine flush leads to lower oil operating temps.
I used 1/2 of this product to flush my 2014 Porsche Cayenne 3.0 turbocharged diesel prior to doing an oil change with 142k miles. Not wanting to give a glowing review of the product until I had a chance to see if there were any noticeable changes to the engine. It’s been 800 miles since using the product and I have noticed after starting and monitoring the water temp, oil temp and oil pressure the engine oil temp definitely remains much cooler than before and doesn’t reach what I believe is the normal operating temperature until having driven 3-4 miles, while the water temp comes up to normal temps as does the oil pressure. I can definitely say the oil temp is lower, which is what I believe this products is responsible for by cleaning out the engine oil pathways! I’m going to use the other half of this product in my 2011 Toyota Tundra with 260k miles. It should be noted I use Mobil 1 oil for both of these vehicles and do oil changes between 5-7k miles.
