i work at a valvoline instant oil change part time now for about 6 months, and the max life line is recommended for vehicles with over 75,000 miles. it has additives in it that condition the seals in your engine so they don't harden as the engine gets older. as far as being a band-aid, i guess it kind of is a band-aid because the seals will eventually wear out no matter what you do. the next question is, does the additives really do their job or is it just another way to charge more money for a "premium oil". i'll let you make that decision, cause only the manufacturer knows for sure and they sure won't tell.
as for adding a fuel treatment for cleaning the engine(per the original post) i add a fuel injector cleaner every oil change, but this is only to clean the injectors and is added by pouring right into the gas tank. there is an engine flush treatment that is recommended every 20,000 miles to clean any build-up in the engine. this is done by pouring the treatment into your engine just like you were adding oil, and then running your engine for 5 minutes, and then doing a regular oil change.
also, any of you with hondas or acuras, that change your oil, when you put the drain plug back in, you need to replace the gasket every time. they have a crushed gasket on the drain plug that "seats" when you torque the drain plug down. if you put a used gasket back on, you run the risk of an oil leak.
