Questions & Answers

If I mix this with engine oil for the purpose of stopping an engine oil leak, will this damage the engine?

Since I've been using it in my engine for 2 years, I have not had a problem except for the leak. Next time I will try oil without it and see if I notice a difference. I have changed oil twice with a little added each time. There have been no problems with my experiences. I found I was able to use it and it worked for me. They may be able to make one specifically for those engines.

Is this product also capable of sealing leaks in an automobile engine, power steering pump, automatic transmission, and differential?

It will work well with all oil based fluids and is very easy to use. Please follow the instructions on the bottle for the correct ratio

The capacity of this container is 2gallon. A 2 1/2 gallon container would be appropriate. ?

Each bottle holds one gallon of product

Do you think you can use this on a Mercedes?

Since I have not used it myself, I have no idea what it is like

Selected User Reviews For Blue Devil Hydraulic Stop Leak (1 Gallon)

The White Shepherd hydraulic stop leak is a good product

5/5

Although I admit I was skeptical of the stop leak, it turned out to be a good invention. During the busy season, I did not want to remove my skidsteer loader to work on it that deeply. I had a leak in my New Holland L555 skidsteer loader that bothered me. Leakage out of the rear seal is well known for the 108). Those were the last words they heard! Having used this equipment for over 100 hours without a problem, it seems to work perfectly. This sealed the hydraulic leak completely, as well as stop the engine oil leak completely! Originally, I was going to disassemble it, but I'm going to leave it as is. So far, I've been nothing but happy with the product! In fact, I'm going to buy more for my other equipment because I'm convinced that it's an excellent product.

5/5

I have seen this stuff work. There was a leak in the swing cylinders of my John Deere backhoe. It was time to change the fluid so I put this one in. We have no longer had leaks.

5/5

I called Blue Devil before using it, and it looked like water flowing in. We used it on a machine that had a leak in a difficult to reach area. It worked like a charm, we have been using it over a year without resealing the pump, it won't fix every leak but it is amazing what it can do.

3/5

The leak in the hydraulic system has to be repaired by a mechanic. The guarantee states that it will be honored. It will be interesting to see if the money is refunded.
