Give your improving MPG ideas

Not sure if this is the right place to post this, let me know if not.

I have a new 2018 regular gas Touring L.

Looking for ideas. Inexpensive, relatively easy improvements that you may have made, and how they've worked out.

Getting out of a Civic where I was around 30MPG average. So far, after a week in the van, I'm averaging 20MPG. I'm doing all city driving, stop and go commuting. Know it's 2 vastly different vehicles, but thought I'd ask for help to maximize my van mileage.

Thanks for any input you may have.

Are you using the ESS? Other than that, coast to stops, light on the gas pedal, keep the speed to a steady 50 mph which isn't too likely in city driving. Looks like you are doing pretty good for mostly city driving.

Buy a good dial tire gauge and keep tires inflated 2-3 PSI above what the door sticker says. Check the pressure regularly.

Forget about the door sticker. What does the sidewall say? Inflate to there.

No, that is incorrect. Optimal pressure is based on the vehicle, which is found on the door sticker. The sidewall usually has the max cold pressure for max load, which is usually way above recommended.

Personally I keep it slightly above recommendation but nowhere near max cold/load.

Optimal for what? A cushy ride that some focus group loved. Ford went so mushy once that Firestone got blamed for their rollovers.

I'll let the suspension and overall mass soak up the bumps, and I'll make the tires as hard as the tire manufacturer rates them for. Mushy tires burn gas like roof racks.

The single thing that most affects fuel efficiency in any given vehicle is the driver and their habits / their right foot.

The driver is the key

I always anticipate traffic lights to avoid a complete stop, if possible, especially if no one is behind me. So doing can be annoying the drivers behind me who are jack rabbits.

When you look at the MPG gauge you see how much gas is consumed starting and stopping.

1975 Plymouth Valiant
1989 Plymouth Voyager
2005 Chrysler T&C

No. I hope nobody follows your advice.

I think the Ford/Firestone controversy was over 20 years ago, that's literally the last century. And Ford's recommended settings was ridiculous from what I remember, well under 30psi (dont quote me, I'm too lazy to google). A lot has changed since then, obviously.

Setting the pressure to tire max does help rolling resistance, but at the expense of handling, braking, cornering, wet conditions, dry conditions, snow conditions, pot holes, tire wear, contact patch, and yes comfort, as well as probably a bunch of other things I can't think of off the top of my head.

Running tires at max press is absolutely sub-optimal.
