Valvoline now has another rebate program going. You must buy a 12 quart case, or 3 jugs, of one gallon or more. For the conventional, it is $10.00. For the Durablend and MaxLife Blend it is $15.00. For the Synpower and MaxLife synthetic it is $20.00. For folk that like MaxLife, that comes out to $10.50 for a 5 quart jug. For Synpower, that would be $15.84 for a 5 quart jug, and for the conventional it would be $9.67 for a 5 quart jug.
