    I live in Denver. Our three grades here are typically 85, 89, and 91 octane. So the lowest is lower than the manual recommends, unless I really did misread it.

    I guess you are right, and I am wrong. I have been to CO and never saw 85 octane. Even CA, which has the most stringent emission requirements does not sell 85 octane.

    Does it have to do with the lower air pressure, lower O2 concentration in the mile high city?

    I really don't know why it is. I should look at the pumps again, I guess, but I've looked 2 or 3 times. I knew that 91 was the highest, so I just assumed the others would be 89 and 87, but the lowest one is 85 instead.
  • Any opinions or information out there on whether Costco regular gas is just as good as Chevron regular (or other "Top Tier" certified brand)? It seems like I get better mileage with the occasional tank of Chevron, but it is probably just my imagination. Thanks.

    Acetone? I guess if you do it, it wouldn't hurt the engine. Care to give some details? Thanks!

    I can't post links, as per agreement, because the site that explains what is at work happens to have a forum board. But if you search for Honda and SUV and then search for acetone thread, you will get all the details.

    People have been adding varyous proportions of Acetone to gasoline (not gasohol) and getting improved and not so improved fuel economy. The general ratio that works is about 2 fl oz. per 10 gallons. This is why I add 3 oz per fill. It usually takes about 12 gallons to fill, but the tank's capacity is listed at 15 gallons. I do this with Mobil brand of gasoline as I know it has no ethanol. Cheaper gas from reservations and wholesale clubs is of unknow origin. The fuel economy suffers when acetone is added to fuels containing ethanol (gasohol).

    Last time I filled up at the Indian reservation and added 3 oz of acetone. I don't know what the fuel economy is going to be, but expect it to be worse than Mobil gas. Generally, I am getting 10% improvment in fuel economy with acetone. Some people on that board reported as much as 30% improvment.

    I use HPLC grade acetone that I get from work. Most hardware stores sell lower quality acetone, which does not seem to have a negative effect on the fuel economy. I have not tried hardware store acetone.

    tamaraster, be sure to post which model of 2005 as well. Helps to know if it is a AWD or FWD, and AT or MT.
  • tamarastertamaraster Posts: 107
    Oh yeah, sorry about that! It's an AT AWD EX.
  • Steve,
    :confuse: I filled up my tank completely and put odometer "A" in zero by the time it was empty "A" read 180.1 miles. Now that's 12.3 gallons I poured into the tank divided by 180.1 and that's 14.64 mpg. Do you think this is a Lemon? The dealership told me in my face today that the CR-V would normally spend 12 to 14 mpg. I am complaining to Honda about this.

    You have to fill up after you drive the 180 miles, and use that number of gallons to divide by..

    Otherwise, you have no idea how much gas you used out of your tank.. A common mistake..

    How is your driving? Speed limit? Racing from light to light? Stomping on the gas? Carry allot of stuff, family members, frequent stops and engine start ups?

    I get 26 mpg in 95% City driving. I shift at 2500 RPM's, almost never exceed the speed limit (which is 35-45 in my town), and don't race from light to light, but rather time it so that I don't have to stop at every light.

    This is different from when gas was $1.50, I would have been at the "head of the pack" Now I drive like an old lady. There some old ladies that actually drive faster than I.
  • 2005 CRV EX AT
    Tires at 32 psi
    Odometer under 3,000

    Traveled from central Connecticut to central Maine
    total miles 672
    total gas 25.48
    avg mpg 26.4

    The trip Nawth was in heavy traffic with some construction delays. For this 280 miles, the CRV did 26.6 mpg.

    Returning home, with much lighter traffic and frequent use of Cruise Control set at approx 65 mph, the CRV did a bit better than 28.

    Local trips amounting to 100+ miles, the CRV avg 22.24 mpg. Although the town in Maine has only one traffic light and is surrounded by blue highways, the local mileage was only marginally better than I get in Central CT suburban stop and go.

    Overall I’m getting what Honda promised and may get better with break in.
  • steve,

    can you tell us how you changed your driving style? apologies if you already did and i missed it.

    :shades:
  • 6,820 miles, 22.84 avg mpg, 60% city, 40 % hwy. The vehicle is not drive hard and is not driven over 70 on the interstate. Latest trip, 1002 miles, 24.66 mpg, 90% interstate, 10% traveling thru small towns. Best mpg 26.73. Currently 18.37 mpg, 9 mile commute to work with few stops. Exxon, Chevron, Shell, 89 octane.

    "can you tell us how you changed your driving style? apologies if you already did and i missed it. "

    Well, keep in mind that I have a 2003, which has a 4 speed transmission.

    Basically I accelerate briskly, but do not exceed 2500 RPMs. I try and get to 35 MPH in town (generally the speed limit) as soon as I can without exceeding 2500. Sometimes I have to let off on the accelerator pressure to get the engine to shift into the final gear (usually at around 30-35 MPH). Then I watch my Tach - I have found that I can maintain 35 MPH on a level surface with 1500 or so RPMs, but if I'm not careful, the RPMs will creep up, without a significant increase in speed. I can't really explain that, except that maybe the traffic is influencing me. When I first realized this, I found I was driving about 1700 -1800 RPMs for just about the same speed.

    I have found that this generally keeps up with most traffic - nobody honks their horn, anyway. Those that stomp on the gas are generally about 50 feet ahead of me at 35 MPH. Well, OK, if they really stop on the gas, they are 100 feet ahead.

    This includes something that is also a safety enhancement - I find myself watching the traffic ahead so as to compensate for the "accordian effect" normal to traffic. So I am more alert to upcoming problems.

    The other tricks are to try and time the traffic and the lights, so that you don't have to speed up and hit the brakes all the time. Every time you accelerate that 3500 lbs of metal, it takes more gas. So try and time the lights such that you make them, especially if you go the same route every day. Which is another thing, check your various routes to work and see which one provides the most consistent speed at approximately the same distance.

    My "bad" MPG (18.3 MPG) was when I really dipped into the VTEC, with "jackrabbit" starts that went into the 3000's for RPM. I actually got the RT4WD to kick in often, which seldom happens now. It sure was fun though...

    One note: I don't skimp on the gas when accelerating onto a freeway, or passing. I usually get up to 4000 RPM on the on-ramp. And I never hinder traffic, not ever. I'll use a little more gas first.

    You will also save if you stay at 65 MPH. My absolute best tank was in New Mexico last year. I went about 60 MPH for 1/2 of the tank, and 80 MPH for the other 1/2. I got 30.8 MPG (as I recall). I've often wondered what would have happened if I'd gone back by the secondary roads instead of the Interstate, but we found ourselves 180 miles North of Santa Fe, NM - all the way into Colorado, in my misguided attempt to get back from Taos. Don't ask for details, it is painful to a person like me who generally has a very good sense of direction. :blush:

    Beautiful scenery, however, in the fall. I also found the neatest ski resort nestled in the mountains. I was trying to get over those same mountains, but when the road turned into dirt, I decided to circle around the mountains on the paved roads. It turned out to be a rather large circle. :D

    BTW, I was over 400 miles on that tank, which is unusual. That was only the second time I've gone over 400; the other time I got 27.5 MPG, which tells you that I was running on fumes when I stopped at 410 miles. I missed my exit on the interstate, and in some parts of Arizona, and California, that means a lot of miles to the next stop. I put in around 15 gallons as I recall.

    My mileage increased at about 3000 miles.
  • 05 CRV SE...89 octane

    The CR-V doesn't need 89 octane. Save yourself some money and use 87 if it's available. I think you'll find that your Owners Manual says to use a minimum of 86 octane.

  • At my most recent fill up, I had again driven only in the city (results reported above, but I'll recap). I mostly commute 8 miles to and from work every day in the city - not with bad traffic, but not without stoplights and the usual mess.

    My last tank's mileage was 20.9, and for this tank I got 21.9. I'm really satisfied with these numbers. I use 85 octane, which is what the lowest grade sold here in Denver is.

    My CR-V has about 1600 miles on it, so it has whatever oil & tires came with it.

    My mistake. I run 87 octane in all my vehicles. I had a 93 Camry SE, V6, 5 speed that I ran 89 octane in.

    I run 32 psi in all vehicle tires. Road noise in the CRV seems to increase with tire pressure.
  • 05 EX AT 2300 miles

    Front tires: 34 psi
    Rear tire: 32 psi

    Drove 1111 miles (started w/ an empty tank and ended w/ an empty tank), with 650 highway miles and the rest was city miles; with AC on half of the time. Total was 43.9 gallons. The average mileage is 25.3 mpg.

    I have had my CRV for about 2 months and have been monitoring the MPG pretty close. My driving consist of about 60% highway and 40% city. The best I have done is 25.5 mpg the worst has been 22.5. All on 87 octane.
  • Just drove on a trip (90% highway, 10% city) for 292 miles (mostly level). Temperature in the mid 70s. Filled up at same pump as before. Costco gas. Just over 30 mpg. Fronts at 35 psi, rears at 33 psi. OEM Duelers. Last fill up at 1030 am, this fill up at 1130 am.

    Anybody know if there is an appreciable difference in shutoff points between pumps at the same station and vs. pumps at a different station? In other words, if you don't fill up at the same pump that you used last time, how much might your mpg calculation be thrown off?

    I bet that your speeds were at 65 MPH or less?
  • Yes, speed no more than 65 mph, no A/C, no cruise control.
  • stevedebistevedebi LAPosts: 3,797
    "Yes, speed no more than 65 mph, no A/C, no cruise control."

    Yes, that checks with my 2003, which has only the 4 speed transmission. The CR-V does really well at secondary road speeds. Though my 27 MPG at 80 MPG isn't bad either.
  • Just wondering if my mileage will get better after I put more miles on it , it only has about five hundred miles now
  • stevedebistevedebi LAPosts: 3,797
    "Just wondering if my mileage will get better after I put more miles on it , it only has about five hundred miles now"

    Mine got better at around 3K, but you also need to drive conservatively in town; if you dip into the VTEC, the CR-V mileage plummets.
  • ok, great to hear,the mileage doesnt seem to good right now. I do mostly city driving stop and go . I hope it gets a little better after it gets a few more miles on it

    Unfortunately, that is the worst cycle for all conventional (non hybrid) vehicles. You will probably max out at 21-23 MPG, but I'm not sure what the 2005 (with it's 5 speed transmission) is capable of.

    My tips:

    Accelerate firmly, not gently or hard. Keep the RPMs below 2500. When you hit 2500 RPM, let off on the accelerator to let the transmission shift.
    The idea is to get into high gear as soon as possible, and stay in high gear
    Try and avoid stopping and accelerating by watching the traffic and the traffic lights
    Plan your route to avoid slowdowns, traffic, and lights
    Time the traffic lights if you can, accelerating or slowing so as to make the green. I see many people (daily) accelerating hard just to get to that next red light.
  • I will take 21 - 23 MPG, thats not bad, thanks for the tips
  • My wife drives the vehicle, she does not drive very fast or aggressively, mostly around town (45-55 mph). We bought a 2005 CR-V EX automatic in June and it has 2K on it right now. The AC is always on as it has been hot here in NC since then. I'm hoping with more break-in miles, less AC usage in the near future, and using Amsoil after the first 5K oil change will help things. I certainly thought it would get better mileage than it has so far. We use Amoco 87 by the way.
