Tactrol is Petro-Canada's trademarked name for an additive used in its gasolines.

Petro-Canada claims that Tactrol prevents the build-up of deposits in automobile engines. Tactrol is used in all Petro-Canada gasoline, but the SuperClean brand contains more Tactrol. Petro-Canada also sells Tactrol in bottles.

The formulation of Tactrol is proprietary to Petro-Canada. Petro-Canada describes Tactrol as acting "like a detergent", but there is little independent scientific verification of the efficacy and safety of this substance.
