Does the 2014 Acura MDX Use Premium Fuel?

"Does the 2014 Acura MDX use premium fuel?"



Acura says the redesigned 2014 MDX will require 91-octane premium gas, the same as other Acura models.

Regular gas (87 octane) can be used for short periods, but Acura warns: "The use of regular unleaded gasoline can cause metallic knocking noises in the engine and will result in decreased engine performance. The long-term use of regular-grade gasoline can lead to engine damage."

Among the changes for 2014 are a new 3.5-liter V-6 engine, a 275-pound weight loss, a front-wheel-drive version and higher fuel-economy ratings. The all-wheel-drive model has EPA estimates of 18/27 mpg city/highway, compared with 16/21 mpg for the 2013 MDX with a 3.7-liter V-6.

The thirst for premium fuel was the main reason I traded in an otherwise perfect MDX. I think 27 mpg highway might make up for some of the extra cost of 91 octane I faced with my 2008 mdx, that averaged about 17-18 mpg in combined driving, prolly around 20 on the highway. I wonder how much efficiency would be sacrificed if the computer could be reprogrammed to run on 87?


Another reason not to buy this minivan.


Never have understood the Premium fuel problem. Simple math, drive 15k per year get 20MPG overall and that= 750 gallons per year. Pay an extra $.30 per gallon it cost an extra $225 per year. That is if you assume no increased economy by using the higher octane. On a $40 to $50 vehicle it seems minor.


We are all born ignorant, but one must work hard to remain stupid. Jim has apparently mastered that task.


Agree with WM. People will complain about the use of "premium" fuel, will drive out of their way to pay a few cents less per gallon, etc but don't realize that slowing down 10 mph will more than make up for that difference. Oh well, if everybody was thoughtful and understands basic arithmetic, then we may actually be more competitive in the world enconomy


I thought they discontinued this model

I own a 2014 Acura MDX and can attest as someone who has actually read the owner's manual that the answer on this web page is WRONG. Here is the what the owner's manual actually says about the use of regular fuel in the 2014 MDX:

■ Fuel recommendation:
Unleaded premium gasoline, pump octane number 91 or higher.
Use of lower octane gasoline can cause occasional metallic knocking noise in the
engine and will result in decreased engine performance.
Use of gasoline with a pump octane less than 87 can lead to engine damage.

Regular gasoline has an octane rating of 87 so according to Honda, it will not harm the engine.

See p. 383 (384 in the Adobe Reader) of

Honda also recommends the use of Top Tier gasoline. (See

In my limited experience with my new car, the 2014 MDX is unusually sensitive to the choice of gasoline so regular gasoline may not be the most economical option despite a cost differential of up to 15% in some markets.
