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.

          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.

                      I have used this stop oil leak on 3 different cars. Worked perfectly on a 2001 ford mustang gt I had a rear main sealoil leak on! Stopped leaking after about a week but you have to drive it about 100 miles like it says on bottle. I just used it on 2 other cars and will check oil and under cars to see if lives up to expectations like I think will. Trusted product, will always use on cars with oil leaks that I buy in future, saves money than going to a mechanic shop that's going to charger over 400 bucks for sure!!!

                      Comments about BlueDevil Oil Stop Leak:

                      My 189,000 mile sedan has a moderate engine oil leak (need to top up every 2 weeks). I was hoping this product would fix it without expensive repairs. Based on other reviewers' comments, I changed the oil, added Oil Stop Leak, then drove on and off for over 2 hours. The next day, the oil leak was still there. Thinking it might take some time, I kept driving. About 3 days after application, panic!!! The oil pressure light came on. After making sure that the oil level was still full, I ignored the light. It has stayed off ever since. Maybe the additive fooled the oil sensor??!! It's been 3 weeks, and I've had to top up once. So the leak has improved but didn't go away.

                            Put this in a '95 Camry 4 cyl. with about 160K miles on it and within a week the rather large rear main seal leak lessened to a few drips overnight. Then after a few weeks it stopped leaking altogether. But alas, it did start leaking again after about 2 months. But it never leaked to the level of what it was beforehand which was substantial. After 5 months still no regrets buying this product.
