You're wasting your money by purchasing 91 octane. Buy 87 octane and if it really bothers you about how long it sits in the tank, add some Sta-Bil fuel stabilizer to the next fill up.Because all our fuel in CA has ethanol, I put in premium (91 octane) as opposed to regular 87 in all our cars...
Octane and ethanol doesn't matter - I use premium fuel for the other ICE cars we have - required for our BMW and Land Rover.How does the 91 octane help with the ethanol content?
It's your money and if it gives you peace of mind, go for it. However the reality is that octane has nothing to do with the storage shelf life of E10.Octane and ethanol doesn't matter - I use premium fuel for the other ICE cars we have - required for our BMW and Land Rover.
I figure using premium in the Clarity can't hurt and since it does not drink gas, 91 octane would be in better shape after months of sitting in the tank.....
The oil barons love it when folks think they are buying 'better' gas when buying 91 octane or higher. Gives them that extra profit they need to boost their stock dividends.I can also confirm that getting an octane of fuel that's higher than recommend won't give you anything in return. Many studies have proven that unless you have a high performing vehicle, typically found octane ratings won't have an effect.
That's good advice, I plan to do just that. I can purchase Top Tier Phillips 66 100% gasoline at a local gas station. 100% gas costs .30 to .40 cents more per gallon than E10, however.The only “better gas” is Top Tier brands vs non-Top Tier brands. Modern fuel efficient engines can really benefit from gas that meets the Top Tier gasoline quality standards. The price difference is negligible, if any.
Being our Claritys need gas so infrequently might as well make sure you follow the Honda manual and buy gas from a brand that is a listed Top Tier brand.
