I think it'd be neither here nor there. The N/As are designed(?) to run on the cheap gas, but I don't think higher octane will hurt (or help)

I seem to get better mileage from the lower octane gas, but I run the midgrade anyways. Partially because it'* the same price as the regular at my favorite station. Partially because part of my brain still thinks higher octane is better, even though the rest of my brain thinks it'* hogwash (for our N/A engines anyways)

it is going to matter very little, with an NA application like ours, it will make a performance difference. You should spend teh extra money to buy from a repuitable gas station instead, to make sure the quality is atleast consistant

I know the L27 (not sure on L36) is designed to run 87. That'* all I run. Always from the same station, to.

However, premium grades of petrol often contain more energy per litre due to the composition of the fuel as well as increased octane.
