Well, just placed an order for a bottle. Will be trying this, in place of Maxlife, and see where it goes... Car: 96 V6 Camry, 1.25 to perhaps 1.5 qts per 5500 mile interval. Culprits are cam seal, and to a lesser extent, rear main. 225k, not worth fixing at this stage of the car's life. Will make for an interesting experiment... Will post updates down the road. Anticipate changing my oil in the next 2 weeks.
