My Trax MPG

My LS FWD is getting 29.5 in town.


Sent from AutoGuide.com Free App

Mine was at 30+ in the fall when it was warm, but now that it has gotten much colder I'm in the 27 range.

I did hit 34 in the fall when I was trying to get great mileage, so I know the car will do it if I want to get the increase in MPG.

Cold weather along with the winter fuels they use here in the Northeast are known for taking at least 2 mpg off any car my miles will be back in the spring.

Great to hear though. Much better than falling below the advertised numbers.

I was always good at getting more gas mileage than advertised.

Have you guys checked out Fuelly.com to see what owners are reporting as average for fuel economy?

Average fuel economy on the site puts the 2016 model at 28.6 mpg and the 2015 model at 27.4 mpg.

Are there any appreciable differences in performance or MPG gained by using medium grade or premium fuel as opposed to top tier regular?

on my 2016 AWD LTZ trax I average about 23 mpg in town but my average mph is 19, my question is what is your guy's mph average when you get up to the 30's mpg.

I get average of 34 mpg but i do alot of highway driving and the Trax is tuned using TriFecta tune i have used it in my cruze i had also love it really give that !.4l a kick lol.

I'm at 29.9.. Mostly highway, and I don't try to be conservative in my driving habits.

Can't blame you because coming from the type of cars most of us have, regardless of how we drive with the trax or any new vehicle we're still well ahead in fuel consumption. Coming from a 90's Town Car I was lucky to see 20MPG :S

Yes that would be a huge difference from a big V8 to smaller 4 cylinder i do have a lead foot sometimes and the cruise control is my friend too.

Depends on your location. Here in Eastern Canada Premium has no ethanol, Medium grade has 7.5 percent Ethanol and regular has 15 percent Ethanol. Ethanol has a very direct effect on gas mileage. I use Premium. When adjusted to compensate for the lost energy of Ethanol content. I'm looking at a premium of 2 percent. Well worth it to me.

I tried several tankfuls of all three grades & the only difference I felt was in my wallet.
The TopTier thing is a sham. All off the gas companies get their gas out of the same storage tanks at the end of the pipeline from the refinery.

There are two grades coming out of refineries. Regular with 15 percent ethanol and Premium with no Ethanol. The medium grade is a 50/50 blend of the two, hence the 7.5 percent ethanol content.

We provide a brief guide to help you determine if your vehicle can run on flex fuel. MPG. Due to ethanol's lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content.

All base fuel comes through pipelines, when it is sold to someone like Exxon, the Exxon additive package is added to make it their gas.

Every fuel seller has their own mix of additives, this additive package is added before the truck leaves for the station, where it is stored for sale.

When the gas go's through the pipeline its just garden variety gas.

When is the "packet" added? When they fill the truck at the tank? By whom? The driver?
The truck goes from the tank farm out to the gas stations and back again.
I've googled this and can't find any info about when this so called "packet" is added.

The additive is added at the terminal the additive package is added to the tank truck, it gets mixed in with the fuel as the truck travels to the destination.

I really don't know how much of this additive is used per gallon, I would imagine its gallons of liquid that is pumped into the tank along with the base fuel.

The tankers have compartments that can be filled separately, a truck can go to several stations delivering different kinds and grades of fuel.

I'm getting 30.5 on average when running stock Summer tires, and 26-27 in the Winter months running snow tires. Winter tires are same size and diameter as stock tires. I'm sure the lesser mpg is a combination of tires with higher rolling resistance, Winter fuel and pushing snow. If I'm on the highway running 75-80 mph, it will drop down to about 30 mpg on a long run. I have gotten 36+ on a long (200 miles) trip using all secondary roads. I'm happy, hope the new Equinox I'm considering will be close with the 1.5 engine.
