Hello,
Recently got what I assume is premium gas from Fred Meyers. I wasn’t sure what the gas was because I was in Oregon and you’re not allowed to fill your own gas so I asked the guy to fill it with premium.
My question is... can low octane cause the car to run lean? Under any kind of load, my car typically adds 0% short term. I run a ktuner and am always monitoring fuel trims. After filling up with gas from Fred Meyers, my short term fuel trim under load is ~+3% and under heavier load the fuel trim increases to ~+7%.
Any insight would be greatly appreciated. Thank you.
