Issue / Question:
If I use lower than the recommended Octane of 93 for example 89% would that cause any engine problems?

Unless your Racing, Pulling or hauling heavy loads 87 octane is fine
but since lower octane fuel evaporates faster then higher octane fuels
carbon is more common to develop on intake valves, combustion chambers. and tops of pistons. For this reason we recommend adding the Amsoil PI fuel additive at least every Amsoil oil change to clean any left over carbon. Follow this recommendation and enjoy the savings.
