I believe that Australia rates their octane differently than is done in N America (US at least). So I think his 91 fuel is equivalent to 87, or "regular" in the US. And 98 is equivalent to our "premium" 93. If you're getting engine knock, switch to a higher octane fuel. It's not uncommon for engines with very high mileage to form carbon deposits within. These deposits can cause hot spots that cause pre-detonation, AKA knock. A fuel with more octane has more ignition resistance. Should side-step the problem.

So we just top up with 91or e10 fuel after most shifts and put up with pinging/knocking/rattling engine noises. |
