    What is your recommendation for stopping a dripping transmission oil leak in a 6 gallon capacity oil sump, on a 1980 model case tractor.

      The best product for the leak you have described is the BlueDevil Transmission Sealer. You will need to add 24 ounces (1 bottle and a half) based on your fluid capacity. Keep in mind that it may take a day or two before you see full results.

      Feel free to contact us direct at 888-863-0426 with any further questions.

    I have an antique 1954 DeSoto Firedome V8 that has an oil drip. I’m not sure where its coming from, most likely the oil pan or rear main seal. If I add a bottle of Red Devil Oil Stop Leak could there be any possible harm to the motor? Will the product coagulate in the oil filter or elsewhere?

      There is no chance at the BlueDevil Oil Stop Leak harming your engine in any way. The product does not harden or thicken so you will not have any clogging or restriction of flow. Due to the fact that this is an older vehicle keep in mind that BlueDevil will not work on old cork seals. Not all older vehicles use cork but if this one does it will not allow the product to work properly.

    I have a 2001 Jeep Cherokee automatic transmission.
    Water has entered the oil and trans has stopped working.
    Do you have any treatment product that I can try to fix the transmission?
    Hope to hear from you.

    I have a 04 Cadillac SRX. I am experiencing oil leakage from my engine and have been told that my valve covers need to be replaced. Is it possible for blue devil to prevent the leakage until I can afford to replace them????

      Yes, you can definitely use the BlueDevil Oil Stop Leak for your leaking differential. You will not need the full bottle; you should add 1 ounce of BlueDevil per 1 quart of capacity.
