Rating 4.5

Engine noise:

I bought AT-205 Reseal additive and added it to the motor oil. Motor ran smoother & quieter immediately. I drove the car about 300 miles with the treatment in my oil and fuel, then did another fresh oil & filter change. Wow...Motor oil was filthy and black - with just 300 miles. ??!! Oil consumption - almost completely resolved!

Pros: motor ran smoother, quieter

Cons: motor oil filthy, black

Vehicle: Toyota Camry

Mileage: 482 km

Part number: AT-205
