MPG and other questions by ssinohio

How can you get an accurate manual reading? 1.) How do you know how much is left in the tank? After the miles to empty reading gets under 25 it just shows 2 dashes. If you fill up and record how many gallons went in, you still don't know what was/is in the tank. 2.) I've always been advised not to let the tank get under 1/4 full which would make this tougher. 3.) When do you stop filling up? After I ran it down pretty low I still wasn't sure how much was in the tank. I tried topping off but I had pumped in 1 gallon more than the tanks listed capacity! When I first got the VC I was near 19mpg, but in the last month or 2 I've been around 15. This was after I added tire pressure to 35psi. Also, in the cold weather does the tire pressure go down or change? Do you have to check it more often in below freezing temps? I've also heard you can have your tires filled with nitrogen instead of air at
speciality shops. Any opinions on this? I've been tempted to take the VC back to the dealer and have the fuel pump checked/replaced like someone else stated in post #69. I have been driving mostly city but have taken some short trips on Hwy. Not much difference. Would like to get near 20 if possible. I am planning to switch to synthetic oil after my scheduled first oil change. Is the 1st change scheduled to be done at 3000 miles or 5000? I have just over 2000 on my 07 limited. Otherwise I love the VC. Any responses would be great. Thanks

Yes, absolutely! Tire pressure changes by about 1 psi for every 10° change in temperature.

Since air is 79% nitrogen to begin with there is very little benefit to filling your tires with N2.The benefit to cost ratio is pretty close to zero - don't waste your money!

The previous reply is correct on both points - tire pressure will drop in cold weather and air is already 79% nitrogen, so there's no material advantage to filling your tires with it.
 
As far as manually calculating mileage, the key is consistency. First, fill your tank. Put the pump away when it shuts off, do not top off. Drive until you need to fill up again - half full, one quarter full, it doesn't matter. Record how many miles you drove. Fill up again in the same manner. Record how many gallons you purchased on this fill-up. Divide miles driven by gas used and you're done.
 
Also, with all major oil companies using winter gas formulas right now, this will cause a 2-4 MPG drop in mileage, which might account for your difference. Want 20 MPG? Drive in the right-hand lane on the highway with the cruise set at 65 MPH, or whatever the legal speed limit is in your area. You might get run over, but you'll get mileage too!

what's the deal with tire pressure? by crains

I'm a driver, not a car-person. Could someone explain the science/connection between the tire pressure and mileage? I'm still getting less than I had hoped. Mostly around the city -- stop & go and expressway (45 MPH) -- and I'm seeing an average of 14.5-16 MPG. Took a 6 hr trip to LA (75 MPH) and still not seeing over 20 MPG. All car computer, not manual. Otherwise, I really love this car (08 Limited FWD).

Tire pressure determines how it's going to pull vehicles weight. It should not be high enough to bust the tires or low to cause drag on engine. I hear 35 psi is appropriate to balance out on this forum. I haven't check my VC's.
I get 17 MPG in CIty with 25-45 MPH and 21 on highways..I saw mpg improves littlebit if you drive at 65 MPH on highway. anything above did not matter.
So I feel on highways I am getting 24-25 MPG and its averaging out to 20-21 including city and highway.
But the CUV itself is very great..Smooth.

Having high tire pressure lowers the tire's footprint (the amount of tire that contacts the road). A smaller footprint means that there is less drag (and traction) between the road and the tire. Less drag means greater gas mileage.
 
As an example, if your tire is flat, it has a huge footprint and the tire is creating a huge amount of drag and friction, which hurts fuel economy. If you want to do some mild offroading, say driving on the beach or through some heavy snow, you want more traction so you don't get stuck, so you deflate your tires to maybe 20psi. If you grossly over inflate your tires (50psi), they have very low friction, but cannot do their job of absorbing bumps in the road. The recommended 30psi tire pressure is Hyundai's best compromise between ride comfort and mileage. If you want better mileage and can sacrifice some comfort, 35 psi might be a better number.

Thanks for the posts. Completely makes sense. Now I guess I have to decide how much I want to give up the great ride. One of the things that turned me off after a Suburu CX-9 test drive was the rough, "sport" ride. Great for hugging the ground, but not great for a CUV and a car full of kids.

MPG pulling a trailer by perdido2key

My first trip pulling a 6X10 enclosed ,single axle, V nose,trailer with a 600 lb motorcycle inside got me 9.6 mpg on a 250 mile trip with 75% being interstate.
I was using the select ( manual ) shift mode and stayed in 4 and 5 th gears at speed. Engine rpm at 3500.
Both 5th and 6th gears are overdrive raitos.
The car had plenty of power and did not labor.
Makes me wonder what the mileage would be if someone pulled the max rated 3500 lbs????

You didn't say what your interstate speed was, but your trailer didn't weigh that much to require travel at 3500rpm. It has enough torque to pull at 1/2 that rpm. Your poor mileage is due to not allowing the transmission to get to 6th gear. Try auto mode next time and only shift to manual for down hill breaking or severe uphill grades (if you think it's laboring). I'll bet the trany down shifts before you think of it on the up hill runs - gives you better mileage.

Have you pulled a trailer of any size with your VC ? If so what was YOUR mpg?
Max torque of 257 ft/lbs on this engine occurs at 4500rpm regardless of what gear the trans is in.
Pulling a trailer,with a head wind to boot in this case, is the same as going "uphill" all the time!!!!!!
