premature ign ition and detona tion. Therefore,
buy ing the correct grade of gaso line is very
important to he lp prevent possible engine
damage and a loss of engine performance.

States and Canada has the following octane r
atings t hat can usu a lly be found on the fi ller
pump:
- Premium Gra de: 91 -96 A KI

Explanation of the abbreviations:
AKI = Anti K nock In d ex = (R+M )/2 = (RON
