I have a 2001 BMW X5 which developed a serious oil leak (everytime I stopped, there was a spot). I put a bottle of White Shepard in the oil and after a couple of days of driving, the oil leak was gone except for a small drop here or there. I put in another bottle and after driving for a 3 hrs, not a drop no where. The truck seems to be driving much better also, had white smoke out the back, now no more smoke. I am so pleased with this product, it really works. I'm telling everyone I can about it!!

I purchased this product because of the reviews I found on the Web. After application and driving my car (according to directions), and giving an extra three days- I found no change. The oil leak remains the same. I have a classic car, spent a great deal on it, and thought I might save a little money in the short term, but I did not. Save your money.

Worked for me

By

Comments about BlueDevil Oil Stop Leak:

Have a 2006 chevy express 2500 with over 215,000 miles on it. Oil leak started about 190,000 miles. Very bad oil leak. I used this product and after about a week the leak was totally stopped. At 215,000 still no oil leak. I have had some success with antifreeze additives but am usually skeptical about most of these products. I do have to admit this stuff really worked for me!

About Me Auto Enthusiast

Comments about BlueDevil Oil Stop Leak:

Was hopeful this product would seal a couple of minor valve cover oil leaks (no way I can get to the rear valve cover). From the product description it should have been a piece of cake. NYET! Followed all directions with no results except that I think the leaks got a little worse. Tried to negotiate with Blue Devil for a refund but without the darn receipt - forget it. This is a snake oil scam IMO. If you decide to buy this product be aware that it may make your situation even worse, and definitely save both your receipt and the empty bottle.

          I added Blue Devil oil stop leak to two Chevy 4.3L engines and in both it decreased the oil leak. One almost stopped and the other did improve. I plan on the next oil change to add another treatment.

          Comments about BlueDevil Oil Stop Leak:

          I have a 2003 Ford e150 with 157,000 miles. The engine leaked in three different spots. Leaked enough for one area that even being parked for short time I would see a spot 3 inches in diameter. I added Blue Devil to the engine oil and over a week's time the leaks stopped completely. In that week's time I drove about 250 miles. The leaks slowly disappeared. It didn't happen instantly. Give it time.

                        Hi Nitro_rail, glad to assist you! This is used for pinion seals, gear cases, rellable shock absorbers, gear boxes, axle seals, and gear differentials. This Bars Leak Valve Seal Stop Leak (Part No. VS-1) will work fine for your project. This product works in two ways to help solve most any valve seal type leak. A specially-engineered seal restorer additive restores valve seal size, flexibility and elasticity lost due to engine heat, age and high mileage. An advanced seal polymer works by building a polymeric film around the valve seal to help prevent excess oil from bypassing the seal during normal engine operation.
