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.

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

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.
