Honda Pilot Real World MPG



  • bobncbobnc Posts: 12
    No, my 21.5 average was before my first oil change. On interstate driving I have adverage 23 mpg.

    My first oil change was around 9000 miles. I was surprised that the cost of the oil change at a honda dealer in Nashville TN was only $23.00 and was completed in about thirty min. I hope that my mileage will improve after the oil change.

    Great car!
  • very interesting.. I also have some questions. what is your psi on front/rear tires??? what type of motor oil? do you use 87 or 91 octane? I drive very slow (60-65 mph) and easy on gas.. my 2006 camry le V6 average 28.8 mpg..

    my pilot oil life is 60% .. so I have to drive more. :)

    Front and rear tires 34psi. Oil Honda. Gas 87 octane, Shell.
    I drive on the interstate at around 70 mph.
  • thanks for the info bobnc.

    here is an update. my pilot ex-l 4wd have 4200 miles.. I have been using the highest octane on my pilot since I bought it.. motor oil hasn't changed yet.

    I am using octane 91 chevron, which is also known as texaco.. today I turn off the fan/AC.. I drove 100 miles. 95 % highway. ( 60-65 mph).. I average 21.9 mpg.

    so I really think 2009, 2010 pilot are capable of 24-28 mpg highway driving after 7000 miles.. we should take advantage of VCM.

    I read on the forum that other pilot owners are not happy about mpg.. If you drive speed limit, drive carefully, you will get better mpg..

    Try Shell 87 octane and take a trip with the cruise set at 62-65 mph. :)
  • There is no need to use 91 octane. Chevron is a great gas, so 87 will still have cleaning agent Techron in it. 91 octane does not have more energy in it so it won't give you better gas mileage. High octane gas was mainly for high compression engines to prevent engine knock and engine damage. All cars these days have knock-sensors in them to prevent pinging and damaging the valve train. Save your money for that oil change and maybe switch to synthetic oil. My Pilot gets great gas mileage if I cruise around 55 mph (24mpg). Unfortunately, I don't drive on those roads very often. Most of the time the speed limit is 65 or 70. I am still getting 18 to 20 mpg during regular commuting.

    I believe octane 91 or higher will be better for Honda Pilot. Pilot weight about 4400 lb. Many people are not willing to pay preminum gas on the Honda pilot.. so honda put knock sensor on the pilot which can run 87.

    pilot have 10:1 compression VTEC engine, just like MDX.

    I am running chevron octane 91 to produce full power.. bobnc suggest me to use shell. So I am going to test it out and let you guys know the result.

    >? I am running chevron octane 91 to produce full power."

    I agree with Joe, and for the reasons he pointed out.. No need to burn 91 octane for most driving conditions.

    Under certain conditions, that could result in the combustion chambers getting unusually hot, higher octane could be beneficial. Those are probably covered in the owners manual..

    Driving in the mountains with a full load.
    Towing a heavy trailer.
    High speeds on a really hot day.

    Car companies want bragging rights on fuel efficiency. Doesn't it make sense that Honda would recommend "Premium" fuel if it would get better mileage?

    Compression isn't the only thing involved with needing Premium fuels. Valve timing and ignition timing play a role also. Your Pilot is "Timed" to run on 87 octane. It doesn't analyze the gas you put in it, so it still runs like there is 87 in the tank.
    There would be an advantage with 91 in certain conditions, when the engine might "Knock" and the computer would retard the timing a bit more with 87 than it would with 91.

    I have only used 87 octane. Like other posters here, I don't think a higher octane is needed unless you need extra power for a haul or mountains. I keep my psi on whatever honda recommends (I don't recall off the top of my head). I've never asked about the type oil when an oil change is done. I typically drive 0-5 mph over the speed limit and try to avoid quick accelerations though I also don't "drag out" accelerating either. I watched the ECO light for the first 6 months and used that to help "train my foot" For the size of the car, I'm happy with 18 town / 24 hwy
  • The 2010 Pilot has a 10.5:1 compression w/ 3.471 cc displacement and 253 hp
    (needs reg unleaded)

    The 2010 MDX has 11.2:1 compression w/ 3.664 cc displacement and 300 hp
    (needs premium unleaded)

    Todays standards for gasses are pretty tight, some are a bit better for your engine but none should make a significant difference in mpg.
  • kingfans1kingfans1 Posts: 137
    so your point is the engine with 10:1 compression doesn't need preminum 91 or higher..

    If you look at 2006 MDX which has 3471 CC 10:1 compression, required 91 or higher.

    Of course you can use octane 87 on Acura MDX, but you are going to loose some HP.. for normal drivers wouldn't probably notice.

    I do believe Honda Pilot engine really need octane 91 or higher. because of the weight of the car, and engine.

    Yes, for 2006 you are correct and make a good point. Both the Pilot and MDX have the same compression ratio and displacement (I made a mistake in my prior post, I meant to show 3.471 Liter).

    Yet the MDX gets a higher HP rating? I imagine the MDX engine computer was "tuned" to perform better than the Pilot because it is a premium brand of car (Acura vs Honda) and people expect more for the premium price they pay. This performance tuning, things like increasing the maximum ignition timing through programming of the computer, requires premium gas to prevent pre-ignition or "pinging" during hard acceleration. Thats when timing needs to be advanced the most. If an OBDII sensor detects pre-ignition because the octane is too low for the MDX, it will compensate by adjusting some engine controls, such as retarding the timing. Maximum performance would not be achieved.

    But I don't think the Pilot can achieve more HP with premium gas because it was deigned and programmed to run on regular. I think the computer has its limits and as long as the gas is letting the computer run everything at optimum, then that's all she's got.

    I set the timing in my old truck by manually turning the distributor cap. It also has a vacuum advance and centrifugal advance. These methods are primitive compared to computers but they helped the car run more efficiently. The specs for my truck call for 2 degree advanced. I can advance it up to 6 degrees before I get any pinging. I keep it at 4 degrees to prevent any pre-ignition that I can't hear. I have always run premium in that old thing.

    Anyway, people should feel good about whatever they do. A lot of stuff is opinion (including my babbling) and folks should do the things that increase the enjoyment they get when driving their vehicles.

    Edit: Hey, check it out. Post number 1000 in this thread.

    I always fuel up my car with chevron 91. It always show 420 miles range at 2 different chevron gas station after fuel up.

    today I fuel up with shell V-power, the miles range show 429. I will let you guys know if shell gas brand give me good mpg.

    so far shell v-power is excellent brand. performance is great. no problems going up on the mountains ( 8000 feet ). the car breathe better.
  • I sell Pilots and 87 is all you need. 91 octane is a waste as stated above the engine is designed for 87 and will not perform any better or different with 91. If you beleive it does it is probably because you have convinced yourself of it.

    Every "miles to empty" computer I've ever seen calculates this based on MPGs over the last few hundred miles. Ford, Hyundai, Toyota. Hate to break it to ya, but that computer isn't analyzing the fuel and saying "yep, this gas feels a little better than the last stuff." It just means your driving style and/or how much fuel was in the tank meant mathematically, you'd get a little further on that tank.

    I've read several different articles mentioning how the higher resistance to ignition of premium can be a detriment to your mileage. I don't disagree or agree; I'm no engineer.
  • kingfans1kingfans1 Posts: 137
    Octane 91 like chevron, shell, brand name have more cleaning agents than 87. In the long run of using 91, it will maintain your engine max performance.

    lets say you drive 15,000 miles a year. 20 mpg. regular vs preminum 91 difference is .20 cents. Using preminum will cost you $150 more.

    yea I believe 91 perform better than 87.

    At Chevron (I know at least in Alabama because I have bought it exclusively for years) there is the same amount of cleaning agent in 87, 89, and 93. All feature "Techron."

    I've used 87 in my Honda all of its life with no problems or performance issues at all. I've only got 209k miles on it though, so its not nearly used up.

    Hi jeffinva,
    you mentioned you got 24 hwy. is that 2wd or 4wd? how often you average 24 hwy? I assume 24 mpg only show couple minutes....

    please post the prof.. thanks

    I'm wondering if there is any site that rates gasolines by the amount of energy they produce. Diesel produces something like 17% more energy per gallon, probably because it is denser. I suspect that there is a difference in brands of gas.

    The best car ever was my 98 Honda Accord. It had a sweet spot at 88 mph. More than once I got 27+ mpg at 88 but when I had to slow down to 70, I only got 22 mpg.

    One thing I did notice over the years was that if I used synthetic or synthetic blended oil, the mileage didn't improve after changing oil.

    My 4 Hondas run smoother on premium gas, but I can't tell any difference in fuel mileage.
