PSL10020 Anti-Friction Metal Treatment, 1 Gallon

Fuel/oil industry hates this product because it works very effectively!!! I have used this product since it became available on the market in the early 90's in every engine that i own (with exception to wet clutch motorcycles). My wifes bmw x5 has a slow oil leak and has run dry 5 times now yet continues to run with no problems....this stuff is a miracle product. Simply amazing!!!! Have never had engine problems with any vehicle that ive had it in (about 15 different vehicles). If youre in disbelief. Fafo. You will be pleasantly surprised!

I've been using this additive for many years and it truly works great. Proof that it works is it takes long for my engine to warm up because of less friction. Even though I change my oil when recommended, its not very dirty. Lowered the running temp on my generator by 10⁰.

I used to use this all of the time years ago. It never really let me down, I know people think this is just a snake oil gimmick but I fully believe it works. I've added this to vehicles I own and my fuel mileage has increased so I would have to say that means something. I don't know if it softened the valve seals or unstuck a piston ring but I've got a Polaris RZR 900 that my children drive and it would smoke on startup and would usually burn a little oil on every ride but has stopped after adding this to the last oil change. I'm not saying it's a fix for your oil burner but it definitely did something to our RZR. I'll keep using this until they don't make it anymore and buying it in the bulk jug makes it much more affordable than purchasing the individual treatment bottles.

Great product, been using it for years

I have two pressure washer pumps that take gear oil. Adding 10% Prolong AFMT makes a lot of sense, because gear oil is made for extreme pressure lubrication and these high pressure washers can use any extra protection they can get. I will also be adding it to the engine oil on all of my 4-cycle equipment... two pressure washers, generator, lawn mowers, snow blower, portable air-compressor and tiller.

After using this product and my lawn mower.After a few years it ran out of oil.I filled it back up and started it.And it kept running for about 5 more years.It is then I gave it to my niece.She's been using it 2 years for a total of 12 years i also put it in my truck in 2003 when I bought it last year.The dealership wanted to know what I did to the engine because it still had the same compression as when I bought it.250000 miles later

I've used this stuff for 30 years with no engine issues. Drove a car 200 miles with low oil pressure, thinking it was a bad sensor but actually had a bad leak at the sensor. Drove that car anothe 200k miles before it got totalled and still ran great. Even used on blower motor on furnace that ran 30 years nonstop and bearings were still good when furnace had to be replace. This may be coincidence but I figure it's cheap insurance.

I'm a lifelong mechanic. I've witnessed tests proving the lubricity qualities of this product and even visited a patent library to read the patent. I added it to a NV4500 transmission that accidentally was filled with contaminated oil and began shifting hard, and the problem went away. With new oil also. Bought a log splitter and stupidly started the small motor without oil. Ran it until it began squeaking and I realized what I had done. Added oil and prolong, and it's been running fine for 20 years. This is an amazing product. I use it in everything I own.

es muy muy buen aditivo.
