Does the 2024 Acura RDX require premium fuel or is this only recommended ?

[image] Purebred: Whereas in Florida, the premium 93 octane is up to 10% ethanol, non-ethanol comes in at 89-90 octane. I think it all depends where you are. Here in NC I can get non-ethanol in 87, 90 and 93. The 93 often is at marinas.

[image] tZ1: so I’m thinking of using a mixture of premium & mid grade. Thoughts ? Why would you do that instead of just filling with premium? What could be gained by mixing?

I guess he is going to get premium then the next time Regular . At 15 gallons each time he saves about 5.00 every other time. Which why one wonders why buy a 50000.00 vehicle to start with if 5.00 is that important. Now if he plans to get half premium and half regular at the same time he is really …

Or maybe “save” a few dollars on gasoline…only to damage a knock sensor or some other expensive part on down the road. Sure, makes sense.

[image] VOLVO-V70: The performance difference is not something that people who buy this vehicle care about. People might not care about the performance difference, but they should care about the fuel economy difference. I can’t see paying less per gallon just to turn around and use more gallo…

Fuel economy difference with regular/premium is usually less that 1 mpg. A fuel economy improvement of 0.5 mpg is important to vehicle manufactures to meet CAFE standards. Similar Honda vehicles are certified while using regular gasoline, the MDX is built on the same platform as the CR-V but they d…

I have never owned a vehicle which is designed for premium fuel, nor would I ever buy such a vehicle. However, if for some reason, I did end up with a vehicle which requires, or even recommends premium fuel, I’d pay the additional cost to use the recommended fuel.

Check the octane level of the Costco premium gas. According to the post above from @LoudThunder, your RDX runs best on 91 octane, and that is premium, not mid-grade. Some states have 93 octane instead of 91 for premium, and you should use that. Mid-grade is almost always 89 octane and while your car can run on that, it isn’t optimum. Here’s a list of octane levels for gasoline by state. I’d continue to use Costco 91 octane premium.
