I have been running the maxlife in 3 vehicles since they reached around 75000 miles . They all ran regular white bottle valvoline until 75000 and then i changed to the red bottle high mileage . My work car is a 2003 malibu with 186000 on it now and on 5000 mile changes still uses no oil , my sons truck is a 95 z71 with 160000 on it and no oil use and my truck is a 2006 gmc with 120000 on it, the 5.3 in it has on rare ocassions showed a little consumption but never enough to add before 5000 mile changes .These were all bought new by me and i couldnt be more pleased with the valvoline .
