Stop Putting the Wrong Gas in Your Vehicle

Don’t give them any ideas, or soon there will be premium electricity too!

I haven’t had a car that requires premium so far. Decades ago they used to advise moving up in octane, at least every so many fill-ups, if you were getting pinging noises from the engine. I don’t know if that is still a thing.

If you had an engine that was prone to pre-firing (having a cylinder fire before spark), bumping up the octane would increase the ignition temperature and hopefully eliminate it.

Back in the day, oil companies used to add detergents and other additives to their premium fuels, but they do that with all grades now.

The best way to cut the amount of money you spend on gas is to drive less.

We bought a cheap Electric car for around town...9700 dollars for a 2016 with 18k miles

Cost us less then a penny a mile in electricity. (AND our solar generates more than we use driving )

Our big and comfy MDX is now only for longer trips..keeps wear and tear off of it..and of course we use 91 octane as recommended to avoid relying on the knock sensor.
