$12.00 for break-in additive, $24.99 for 5 quarts Mobil 1 synthetic 10W40 high mileage (has extra zinc and phosporous) than standard.

Synthetic??? My engine has been running on conventional. At least that's what the previous owner advised me to use. I'm pretty sure if I used synthetic it would end up all over my garage floor.

You can also run whatever oil you want and at every oil change,add a bottle of STP oil treatment from Wally World to your oil change......

From what I've read, having high zinc is only half the solution. Modern oils have higher detergent levels. These detergents "clean" the zinc off metal surfaces. Accordingly, a zinc additive is ineffective. Oils like Joe Gibbs have lower detergent levels as well as higher zinc content.

So, if your engine will benefit from higher zinc levels, it is probably wise to use an oil formulated with it instead of trying to add it yourself.

absolutely, adding zinc to a detergent oil is a waste of time.

at 60.00 a case for oil with the good stuff in,... what are you really saving by buying regular oil and putting all kinds of additives in?
