OS-1 Oil Seal Engine Oil Burning/Leak Repair, 16.9oz, 1-Pack | Repairs Leaking Main Seals and Gaskets, Renews Worn Valve Seals and Guides, Stops Oil Burning & Blue Exhaust Smoke

WORKS EXCELLENT FIXED MY PROBLEM ! THANK YOU

The product worked on a 2012 Bmw 750Li that was smoking when at a light, in traffic, or in line at fast food..... Was fine when diving as long as not at a stand still for over 3 to 5 Mins or stop and go traffic..... I fell like it was the valve seals leaking ao I brought this in hopes it would work.... The initial one I was going to try seems to stay sold out..... I decided to purchase before a trip that was 200 miles away to give it a chance to work..... I put it in the night before for 15 to 20 mins 1st and as always it started smoking...... On the trip back 2 days later before making it home we stopped at Zaxby's and about 6 cars were in line.... I say oh boy because it always smokes after a few mins in line soni have to cut the engine off and turn back on after a car move up..... But this time for the 1st time it did not smoke.... I was amazed and kept looking for the smoke but never came..... So the product works.... Dont know if it already worked on the first 200 mile because i did not test until i retured so I drove over 400 miles before i test it.... But no smoke at all...... Probably will cost over 5k to change all the valve seals if not more.

As my car get near 15 years old and still a daily driver had started to experience many leaks. The BMW community says not to use the product in your BMW. I have a BMW 323i and with the age and mileage was looking at putting a couple thousand into repairs so gave this a shot. Multiple leaks were resolved while one weeper persists. Have ran for over a month with minimal oil loss and improved performance. I did end up flushing out the system after running it with this product in it for the month.

terrific, worked wonders

I don't know why I keep wasting my money on these additives that don't work. There is no miracle repair.

Works. Had a small leak and i flushed the engine, changed the oil adding the stop leak with the new oil. Ran the engine as instructed to, no leaks and its been over a month. Was recommended to me, and it was worth it.

0 STARS OR BELOWI bought this oil seal product and IT DOESN'T WORK, and it didn't stopped or even slowed the leak and then I call the company and he told m flately that it doesn't have any kind of warranty, and in order to get my money back I would have to take it to the dealership or a certified mechanic,to have it verified and certified, nobody is going to spend more money and time to get a refund for less of what you are spending, SO DONT BUY THIS TRASHY PRODUCT

It's excellent—I highly recommend it. It stopped the oil leak in my steering system.

I've bought a lot of products before but they didnt totally stop the leakage as what this product did.

Easy to use and does what it says

Magnífico.Tengo una de mis motos con casi ya 40 años y algunas fugas de aceite motor severas. No era una gotita, era ya casi pequeños charcos. Decidí probar este mejunje y el resultado es de 10. Han desaparecido por completo. No hay fugas ni gotas ni nada de aceite ya bajo la moto. Cuesta creer en estos productos milagrosos, de hecho no creía en ninguno pero como tenía mucha pereza y poca pasta para levantar el motot y gastar más de 200€ en juntas decidí probar por las reseñas positivas que leí a ver que tal en mi moto y si! Funciona 🙂Apto para motores con embrague en baño de aceite o sea que lo puedes poner en tu moto sin problema... 😜

Works

Resultados muy buenos, lo recomiendo
