it really worked on my 2007 bmw 740 in dubai
my car smoked a lot on high throttle and when the traffic was busy or parked for 5 to 10 minutes, the exhaust always smoked and smelledI spent a lot of money on some additives, and got advice from the garage for the repairvery high repair cost to replace valve seals, I also ordered many kinds of pcv valve to replace but no successi have tried this product and it worked, it's not 100% but it's also 70%, my car has reduced smoke, and has reduced odor, i think it will work by adding it every time oil

لا استطيع التقييم لأن العطل عندي كان أكبر من ان بحل بهكذا موادوضعته في ماكينة السيارة ولا اعرف ان كان جيد او لالأني ذهبت إلى اصلاح تسرب الزيت نظرا لكثرته فلم يظهر لي جودة المنتج من عدمه

Not as claimed
I purchased it based on what was printed on the product where it seems like it perfectly suited my vehicle because it was burning just a bit of oil over a period of time. Had no change in oil consumption&exhaust smoke. I just went ahead and rebuilt my engine instead.

Still burning oil; Still had to put .5L of synthetic oil after 2 weeks.
At first, it gave a more sensitive acceleration response but apparently still burns oil.

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

Works great for small oil leaks in older car
My mechanic gave me an estimate of $3000 repair for an oil leak. This fixed it.

Funciona!!!
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... 😜

This seals valve stems!
This actually works! I put it in my John Deere tractor and it completely got rid of the blue smoke on a cold startup!
