I have to say, this stuff is awesome. Before the switch, this car burned about a quart per 1,000 miles. Now, after 500 miles, it hasn't burned any at all. It runs very smoothly. And with the exception of some tappet noise, with the A/C off it is very very quiet. When sitting with the windows down and A/C off, you can't even hear it running. Power has improved too. This is some good oil! Valvoline has earned my loyalty, and I will fully endorse and recommend Maxlife in the future.
