  • Wanted to let you know, your oil stop leak fixed my oil pan leak. My mechanic wanted to charge me 800 dollars to replace the seal but you guys fixed it for under 70 bucks! Thanks guys.

    Your oil stop leak is amazing! I had a really bad oil leak from my rear main seal and was losing about 2 quarts a week. I used your stop leak and within 200 miles of driving the leak stopped! Great product...
