Hi everyone. Have been thinking about running Valvoline Maxlife in all my cars. I'm using Quaker State on my Camry since '92. Have switched to High Mileage Q-state just this past oil change. I'm thinking about switching to Maxlife for convenience. I usually purchase Maxlife when it goes on sale. The following week the High Mileage goes on sale. Save myself a trip and use Maxlife for all my cars so I can change both of them on the same day. Are there any engine problems with changing brands? Will there be oil consumption after switching? Suggestions highly welcomed.
