My guess (unfortunately, I did not keep all of my receipts) is that I probably saved enough over the roughly 8,000 miles to pay for our dinner for two in Ted's Montana Grill in Colorado Springs. Best Bison meat I have ever had!!
 
I notice that in our area (Southern New Hampshire), lately, prices are dropping and the difference between premium and regular is shrinking. I will go back to Premium.
 
As an aside, I also own a 2001 Mercedes E320 4-Matic. The drop in mileage from using premium to regular is significant to the point where it is more expensive to use regular than premium. Performance also drops off. Clearly, MB squeezes as much out of their engine designs as possible.

Hi Dave,
 
Thanks for the information. I just brought a 2008 MDX three weeks ago. I have been using only 91 octane gas and has been able to get 18 MPG around town and 23 MPG highway.
 
The price difference between lowest grade (87 octane) to highest grade (91 octane) in California is usually $0.20 which is less than 5% saving. It is clear that the best option is to use Premium gas as there is a 9% reduction in MPG by using lowest grade (87 octane) based on your average 22 MPG using Premium and 20 MPG using 87 octane.

Additives will not help this issue. The lead will render the catalytic converter junk in very short order (it will coat the catalyzing medium). You may be able to remove the catalytic converter(s), but ONLY IF there are no oxygen sensors downwind of the cats.
 
If the MDX has o2 sensors downwind of the cats and you remove them, the ECU will cause the engine to run poorly (generally lean or too little fuel which will reduce power significantly and destroy internal components).

How much does it take to fill up the tank on the MDX...is it more or the same if it a newer MDX?
 
Does the MDX 2010 eat up the gas quickly?
 
I drive mostly highway is the MDX 2010 for me when it comes to gas?

The MDX takes up as much as 21gallons and if you cruise on the range is nearly 400 miles. In terms of factory EPA is 16/21 MPG. If you want efficiency get a hybrid.

hello ireneatlas19 I have 2010 honda pilot 4wd. the car required octane 87 or higher.. But I have been using octane 91 for better performance or engine. I am getting 20 mpg. 90% highway. I drive 60-65 mph.
 
I think 2010 mdx should able to get 19-20 mpg if you drive 60-65 mph highway driving.. but remember your mdx required octane 91..

Thread jack-
 
kingfans1- how do you like the pilot? Did you drive an MDX before? Will probably replace our '07 MDX with a Pilot.

I like my Pilot very much.. It is only 3000 miles.. sometimes I can hear some kind of noise when I press brake.. It is only happen in the morning when the car is cold.. after I drive for couple minutes, and press on the brake, the noise disappear.. I think it is normal.. ( since brakes are brand new, and I don't use a lot of brakes.. ( most of my driving are 90 % freeway).
 
the car is very quiet.. I read on the forum, other pilots owner are complaining about wind noise.. I don't hear any wind noise on freeway driving.. i have ex-l model. that ex-l and tourin model have Acoustic Windshield.. so it is very quiet..
 
2010 pilot is a great car.. When I am driving it, I didn't feel heavy.. My brother have 2008 4runner 4wd v6.. When i drive 4runner, it feel heavy..
 
for now, i am happy with the pilot... I do like acura tl.. I will probably consider in 2 years..

your mdx suppose to get 21 highway mile. it still have special break in oil. so you will get better mpg after your first oil change.. If you turn off the fan/AC, drive 55-65 mph, your mpg will increase..
 
so far my 2010 pilot ex-l 4wd average 21.9 mpg. 90 % highway.. the car have about 4200 miles..
