I generally follow the OEM owner and service manual recommendations, but noticed a lot of 1500 owners regularly use 87 octane which is below the 90 minimum for the 1500 engine.
I tried 87 and the engine runs fine even in hot weather - no pinging that I can hear. In fact, I notice a little better gas mileage using 87 and I think it may even have a little more power, but that could be just my imagination.
But, I'm still a little concerned since the manual states severe engine damage can occur using a lower octane. Could there be any long term consequences using the lower octane?
