BlueDevil Rear Main Sealer, 8 oz Bottle

used in my roommates 2005 silverado that was leaking a ton of oil. the truck has over 300k miles so wasn't expecting it to fix the oil leak completely. The whole underside of the motor was covered, but looked like the oilpan gasket and rear main was where it was leaking the worst. added a second bottle about a month after the first and have noticed a considerable improvement. still leaking, but helped a lot more than I expected.

My car was leaking oil from the rear main seal after they worked on the transmission unfortunately it was outside of the warranty time so they tried to charge me an arm and a leg just to replace some $25 seal. They wanted something like $3000 to the other shop close to 2000 for the work.. I found this blue devil rear main steel fixer and honestly, I didn't expect it to work. I was already buying a bicycle or a scooter to get to work or figuring out what to do for bills and for when the car failed.. The car was leaking half of core of oil every day… now it's not even leaking at all. Not only do I continue to drive my car, but this leak is basically fixed… yeah it might be a Band-Aid and a for now, but it worked. There is a possibility it will keep working, but regardless, I'm happy it got me to the next week and got the bills paid for that month.. I'm going to use one of these with every oil change just to ensure the leak is treated
