Does this stuff work? What does it do?

Hello. I own a 2007 BMW 335i, with over 189,000 miles on it. My car was losing oil and BMW recommended that I do a valve guides seal replacement at a cost of $6262.39. At that time my car was getting about 300 miles or less before I had to top it off with another quart of oil. Since I started adding Oil Saver, I am now averaging 800 miles before I have to top it off. It works by making the rubber pliable again so that it forms a better seal. Not a permanent fix, but worth every penny. Add it when you add a quart of oil, or get an oil change. Hope this helps.

Does this stuff work? What does it do?

The product is designed to penetrate the seals and cause the material to expand, thereby stopping the leaks. I suspect its the same stuff used in high mileage oil, just in higher concentration. It did not stop my oil leak.

Does it have to be added every oil change?

No, not at every oil change, but every 18000-20000 miles to guarantee to keep sealing.

How much is needed for 6 cyl 3.0 liter?

One can will treat up to 6L of oil, so it depends on how much oil your crankcase holds.
