Review: So far, it did the trick! - Well, I bought this because a mechanic put synthetic oil in my friend's 99 Buick LeSabre that had never had synthetic oil. The engine had 175,000 miles on it and never has seen synthetic oil. After running the synthetic oil for about 5,500 miles, a few drops were visible here and there. So, I figured that changing the oil back to organic oil and putting some of this in would fix the problem. I bought this in the winter, but I waited until we got hot weather to use this since I don't know how this will work during -0 degree F starts since it looks very thick. So after changing the oil and filter (using dinosaur oil), I put the whole quart in (I did not overfill). I figured that a 16 year-old engine with 180,000 miles might need to have all the o-rings and seals rehydrated (if that is what you want to call it. The GM 3800 series II stopped dripping the occasional drop after about 1 week. I will take it to the carwash to pressure wash the bottom side of the engine and degrease it, just to see if there is any new oil. But so far, the oil pressure does not seem any different and the oil stopped dripping. So take it from me, putting synthetic oil in an engine that has a lot of miles is not the end of the world. The mechanic put synthetic oil in it because there was the manifold antifreeze leak that could have gotten in the oil. So just in case, he used synthetic once he fixed the antifreeze leak and changed the oil. I do think that the synthetic oil cleaned out some deposits inside the engine. But it only started to leak a few drops, this oil treatment seems to have fixed the problem. I will try and see what happens after the oil is changed again. And, perhaps some can tell me if this would have been OK to use in winter, it sure was thick!
Review: Stopped a rear main seal leak on 2008 Land Rover Range Rover HSE, needs drive time to be effective - TL;DR Worked for my minor rear main seal leak, but you need to drive the car around for 200-500 miles for the stuff to really be effective. I went to the mechanic with my Range Rover (65k miles, regular maintenance) and discovered there was a fluid leak coming from between the transmission and the motor. They weren't sure if it was oil or transmission fluid. I added UV dye to the oil and determined that it was indeed oil. If this was the case, then the mechanic said that it was highly likely that it was the rear main seal that had failed. I read through all of the online forums and found that oil leaks are common with this model, but several people claimed that they tried Bar's Stop Leak, Lucas Stop Leak, etc. and it stopped the leak. A handful of people had a poor experience. I am most familiar with Lucas products so I chose to give this a try before spending $2000 to drop the transmission to replace the rear main seal. To my surprise, it worked. I drove it around for 50 miles and no sign of leaking. I let the car sit for a few days and there was a huge puddle of oil under the car. Discouraged, I thought it didnt work after all. I cleaned up the oil and took a drive (~200 miles) and all signs of leaking went away again. I've been checking every day and it appears that the leak is gone for now.
