Tactrol

Because A Cleaner Engine Simply Runs Better

Tactrol is our exclusive deposit control additive that acts as a detergent to clean and prevent the build-up of harmful deposits. Tactrol is used in all grades of Petro-Canada gasoline — including RegularClean, PlusClean, SuperClean, Ultra 94, and WinterGas™.

SuperClean and Ultra 94 come fortified with an extra dosage of Tactrol — so it can actually remove stubborn deposits, help restore your engine's performance, and keep it clean.

No other company uses Tactrol except Petro-Canada.

Definitions

Reference Fuel — In the measurement of octane quality of gasoline a mixture of two hydrocarbons called iso-octane and normal heptane. Iso-octane is assigned an octane rating of 100, and normal heptane is assigned an octane rating of zero. A blend of 90% iso-octane and 10% n-heptane would have an octane rating of 90 octane.

(R + M) / 2 — The average of Research Octane Number and Motor Octane Number; one measure of the combustion quality of gasoline.
