I wanted to ask what people here think of my plan to add max life engine stop leak to oils you can sometimes get for .99 or so before or after rebate to make them like standard Valvoline Max Life Oil when changing oil this is $4.00 a bottle but worth it if it saves me 2.19 a quart over the price of Max Life($3.19 A QUART CURRENTLY) if all the additives in the oil are concentrated in this little bottle(15 ounces treats up to 6 quarts)?
