Has anyone done a comparison of the fuel efficiency using the different levels of octane? Results?
Ditto.. ;DYosemite said:been running 87 since its been broke in. getting 44-45 mpg and I drive a canon road every day. Hill and turn and anywhere from 30mph to 100mph. I drive it like I stole it and it still gets good gas mileage. Lowest Ive gotten was 39 mpg
Bingo!trigger said:Octane requirements for any engine, regardless of number of cylinders, is subject to compression ratio and ignition timing. High compression engines with an aggressive advance curve require combustion inhibitors to prevent detonation and pre-ignition. There is technology where the ECM can detect pre-ignition and retard the timing. I don't believe the Stryker has this capability. Using fuel with a higher octane rating than recommended will result in a slower burning fuel charge and reduced performance.
