VCM in 2009 Ridgeline EX-L

I just took possession of a beautiful Deep Cherry Pearl EX-L Navi and noticed the mileage rating of 29 MPG on the highway on my factory sticker. I asked my dealership salesguy who replied that the better mileage was due to Variable Cylinder Management in the 09. I am baffled as I have not seen anything that confirms this, but 29 MPG is unheardof in the RL. The EX-L is the Canadian equivalent of the RTL Navi, it appears. I have also checked the Honda.ca website and don't see anything that confirms what my dealership claims. Can anyone offer any suggestions?

I know the 09 US models don't have VCM, I can't imagine the Canadian models would be any different.

Even if it did have VCM no way would it get 29 mpg. LOL maybe they put an Accord window sticker on it by accident :p

I'm thinking the wrong sticker got put on your window. As far as I know, NONE of the Ridgelines have VCM. I think there was some reason (like the aerodynamics) for why they didn't/couldn't use it.

Can you post a shot of your sticker?

The Canadian gallon is larger than the U.S.
My 2007 has a sticker value of 28 mpg highway.
No matter what you own, subtract 15% off what the sticker says for real driving conditions. I get 24 mpg in straight highway driving, summer gas.

I certainly agree with what everyone is saying. I'm sure that running the RL on 4 cylinders on the highway is going to seriously compromise performance. The explanation about the size of the gallon also makes sense. I do not see anything in the manual about VCM and will email the dealer to clarify. I think they'll do some research before putting their quick talking sales guy to a written reply that can be posted for the world to see. I don't have a scanner but I'll try to take a pic of the sticker later.

As pointed out earlier - no VCM on Ridgelines.

MPG figures are calculated differently in Canada and they use Imperial Gallons. So a gallon of gasoline in Canada equals 1.2 US Gallons.

Sometimes we like to use Imperial Litres too :)

To convert you have to add 32, multiply by 5, and then divide by 9.

That gallon/litre conversion process works real well. Ask the pilots of the Gimli glider.

Isn't that the conversion from Cel-Fah?

Lessee now, I always used C* x 2, subtract 10% and then add 32 to get F*. Or if a negative C*, the same but add 10% before you add 32.

;)

(it works too!)

Edit: as was pointed out to me by a member here, I shortcut the procedure which may have confused the issue. Joe... you'll like this addition to the Rube Goldberg equation. ;)

Always subtract the 10% number. If C* is a negative number, 10% of that will also be a negative number. When you subtract a negative number, the double negative becomes positive. OTOH, when you subtract a positive number, well we all know how that works.

When working with negative C* numbers in the example, I shortcut the double negative -> positive number which might have confused some. If you weren't already confused anyway. :D

-100*C x 2 = -200
-200 x 10% = -20
-200 - (-20) = -200 + 20 = -180
-180 + 32 = -148*F

And that's pretty freaking cold, anyway you measure or calculate it!

the easiest way to convert to Canadian units is like so...
fill up your truck.
pay for the gas.
But use Canadian dollars, or you will have to convert again:rolleyes:

Brings to mind the "Tower of Babel" from the Bible.:)

I just read the other side of the thermometer:D

It works too.:D

Your way of converting from -C* doesn't work...You still need to subtract 10% before adding 32.


I always use C times 1.8 plus 32 This also works from negative C

-5*C x 1.8 = -9 + 32 = 23*F

to convert F to C: F minus 32 divide by 1.8

98.6*F - 32 = 66.6/ 1.8 = 37*C

Oh yeah.. it works with -C* too. ;)

For example we know that -40*C = -40*F and 100*C = 212*F (our control numbers)

Edited
Negative C temps:
-40*C x 2 = -80
-80 - (-8) (10%) = -80 + 8 = -72
-72 + 32 = -40*F

Positive C temps:
100*C x 2 = 200
200 - 20 (10%) = 180
180 + 32 = 212 *F

For me, the multiplication is harder to do in my head. I can easily figure out 10% of a number and I can handle the addition and subtraction stuff better than multiplication.

I learned this method from someone during my airline pilot days. All temps at airports are reported as C*. But few people in the USA relate to C*. So when giving passenger briefings, we always converted C* to F*. I learned how to do the math pretty quickly in my head and I've never found my method to fail, unless I had a brain fart and screwed up the math. ;)

Maybe we should give a prize for the most complex formula to covert from liters (no, not litres) to gallons, or celcius to fahrenheit. A Rube Goldberg formula!

Us older Canadians have used both Imperial and metric.
I remember when we switched. One day it was 80 degrees out. The next it was 20. I didn't know whether to put on shorts or longjohns. But we have adapted over time.
So here's my oldtimer wisdom/formula. Maybe not Rube Goldberg, but...

When you get up in the morning, let the dog out to pee.
Time how long before he is scratching at the door to get back in.
If it's just seconds, then it's dammmm cold out, Celsius or Farenheit.:D

Oh yeah.. it works with -C* too. ;)

For example we know that -40*C = -40*F and 100*C = 212*F (our control numbers)

Negative C temps (you have to add the 10% number):
-40*C x 2 = -80
-80 + 8 (10%) = -72
-72 + 32 = -40*F

Positive C temps (you have to subtract the 10% number):
100*C x 2 = 200
200 - 20 (10%) = 180
180 + 32 = 212 *F



Don't you still have to subtract the 10% or am I missing something here?
-40 x 2 = -80
-80 + 10% = -88

-80 - 10% = -72

-80 + 10% = -88

-80 - 10% = -72

RRider, you are correct and I edited the examples and explanation above.

Thanks for catching that shortcut that I left out.

Speedlever,

I tried to delete the last post, but I don't think we can do that anymore.

I do understand how this method is easier to do the math in your head, and understand what you meant now...Sorry for any confusion I caused!

I think I owe the OP an apology for straying so far from the original post too!

Umm, the original post? What was that about? :D

Hi - I just bought an 09 Ridgeline a couple weeks ago - the window sticker said 9.8 Litres per 100km hwy and 14 litres per 100km city - and also noted that was 20\29mpg. i was confused as well but forgot about imperial gallons being bigger.
however - i use this handy website to track my mileage;

http://www.oee.nrcan.gc.ca/transportation/tools/fuel-trip-calculator/fuel-calculator-input.cfm?attr=8

this calculator works great as it shows you mpg imperial, us and litres per hundred.
anyhow - my 09 is getting decent fuel economy already and its been minus 25Celcius here (to convert - that to farenheit - just add another set of long underwear - its too freakin cold to go outside)
its already getting better fuel economy that my 2001 explorer V6 did.

cheers

When I purchased my Ridge, the sales consultant, a.k.a. salesman, told me to rotate the iginition keys on a monthly basis. He said the keys get recharged in the ignition when the engine is running. So I actually did a rotation before joining the ROC.

Just think, if I hadn't joined the ROC, I would still be rotating the keys on a monthly basis.. :D :D :D

Well, at least they would be charged if you were still doing so! ;)
