STP additive

[TTA 1077]

what color bottle of STP additive for our cars?

Red, it has the most zinc and phosphorus and is thinner than the blue.
I buy it by the 12 case from autobarn

Thanks, doing an oil change today, so I'll just grab a bottle with the Red line oil for now! One bottle STP replaces one Quart or just add to to the full 5 1/2 quarts?

Its 15oz, just shy of 1/2 quart.

I add it to the 5 quarts and it is perfect on the dipstick.
