Depends what your tpms system is set to. Mine won't give an error light until 51 psig but if the stock tire size is 44 psi max then it will come on much sooner. Set it 10% below sidewall max so there is room for pressure increase when the tires get warm. I have mine set 38 front 45 rear to help with handling characteristics.

Also, around Southern California the Chevrin stations offer free use of the air pump. You don't have to buy gas to ask for them to turn it on either. EDIT: check in your area. haha

I went out to walmart and got the $10 stand pump and pumped the tires to 42 psi I will monitor it as it starts to get colder. It definitely was elbow grease pumping them up by hand but it wasn't terrible.

When I lived in Ohio we had the free air pumps as well at some places like giant eagle and such. Not here in north Carolina though haha

Started to check out some of the threads here and saw some talking about sealing the gaps around headlights and such and remembered a thread on the veloster forum where members were trying to keep the engine bay clean and bought a hood weatherstrip. For MPG purposes this might help me not having to do an upper grill block and no one would even see it.

Blocking excessive grille opening will have a bigger effect than closing up seams. I'm sure you know you need a way to monitor coolant temps to ensure you don't go too far for your typical driving loads.

---

Does your car have a "manual" shift mode?

I've often found that you can get an automatic to upshift SOONER using manual mode than the default automatic programming permits. That will help as well.

Thanks Metro for the response. I actually mocked up a grill block with cardboard and I am not sure if it is making a huge difference or not. I do have a bluetooth OBD2 connector + Android app to monitor temps.


Yes my car has the manual shift mode and I have been using the exclusively. I actually achieved 41.7MPG on this past tank, my record is 41.9

Something I need to test out after this tank is if it is better to neutral coast or DFCO coast. I will test it out on a full tank. I still need to research on here which is better as someone on the Veloster forum stated the instant MPGs I see when neutral coasting are inflated because it is idling.

It'll be making a small difference. Probably not enough to show up above the usual variability in tank to tank monitoring though.

Very nice. I drove my friend's Buick Regal turbo which has this, so I just went in the "manual" shift gate and regularly bap the lever forward to get it to upshift ASAP. Bap bap bap bap bap. It almost needs a little machine to keep tapping the lever for the driver.

Depends whether you're trying to slow down or not.

Yeah that's what I am assuming as well, I also folded my passenger side mirror in this weekend.

Haha yeah it's definitely an awesome feature to have in an automatic.

Yeah I am still not 100% convinced that the Veloster has DFCO because my gal/hr is worse coasting in gear vs neutral. The instant MPG is also not nearly as high vs in neutral. I have read how to test if it does but I am not keen on cutting the engine while driving.

All modern EFI engines have DFCO. It's a great way for them to jack up city EPA ratings.

FWIW, i have noticed in my car that it will only enter dfco if i am not in manual mode. Yours may be the same. In sport mode and manual mode the ecu will waste more fuel in the assumption that you have the car at a track event or you're having entirely too much fun and need that fraction of a second better throttle response.
