If you have a modern MPFI vehicle; do the routine fluid changes in your car with the fluid, filters, and techniques specified in the owner's manual; and use a high quality gasoline; I argue that you never need the following things done to your car:
Coolant flush*
Coolant additives
ATF flush*
ATF additives
Engine oil flush*
Engine oil additives
Magnetic drain plug upgrade
Fuel Injector Additive
Intake manifold cleaning
Oxygen sensor replacement
*chemical or physical
Please send half of all monies you would have invested into these products to my mailing address and we'll call it even.
