omniphil Posted November 26, 2014 Share Posted November 26, 2014 46 is how the car comes from factory mine is the same My door sticker says 41psi. But I always add more on my vehicles. T0ASTERvan 1 Quote Link to comment Share on other sites More sharing options...

Johnyguy Posted November 26, 2014 Share Posted November 26, 2014 Yes 46 for the rear I think 41-46 is already kind of high gets a little Bumpy If not keep the pressure tire monitor gets annoying. Quote Link to comment Share on other sites More sharing options...
BSUPC Posted November 26, 2014 Share Posted November 26, 2014 My 2012 calls for 40 in the front and 49 in the rear on the sticker. So far this works fine for me. Quote Link to comment Share on other sites More sharing options...
omniphil Posted November 26, 2014 Share Posted November 26, 2014 I've always gone higher than the sticker, it improves gas mileage. And it looks like different versions of this van have different pressures on their stickers. Their might also be different tires for different versions.

Willie Posted November 28, 2014 Share Posted November 28, 2014 . Most agree that under inflation will reduce gas mileage but there seem to be mixed results from over inflation. I believe you when you say it works for you. but others find that it does not help to go beyond the recommendations. http://theframjak.hubpages.com/hub/tire-pressure-and-gas-mileage-does-it-really-matter http://www.popularmechanics.com/cars/news/4199963 Quote Link to comment Share on other sites More sharing options...

It was covered on an episode of Mythbusters and those guys tend to get pretty scientific in their testing. If your looking to squeeze every drop of gas out of your tank you gotta be willing to try these crazy things Quote Link to comment Share on other sites More sharing options...

Ackerdackerly Posted December 1, 2014 Share Posted December 1, 2014 Taking this discussion a slightly different direction... There are two places where I buy 87 octane gasoline for my TC. Both locations are operated by the same company. One offeres a 10 percent ethanol blend 87, the other has zero ethanol 87. I ALWAYS buy at the zero ethanol location because I get better mileage. Time to change my air filter... Quote Link to comment Share on other sites More sharing options...
Fifty150 Posted September 24, 2016 Share Posted September 24, 2016 A major factor effecting mileage is traffic. Sit in traffic with the engine idling, A/C on, and let the fuel burn. If you can idle and burn a gallon of fuel per hour, how much fuel did you burn in an hour raveling 5 miles across town? I tend to leave the engine on so that the A/C can keep the interior cool when I make stops. If I'm inside for 10 or 20 minutes, then it's idling the entire time.
