MPG is on the RISE

[MSG W]

anyone notice a different AFTER they got a Bed cover? I heard it would increase your MPG. Wonder those that post mileage would add if they had a Bed cover.

I've not noticed a difference either plus or minus after installing my Extang Solid Fold 2.0 cover.

It's mostly people selling covers that say that

Coming back from a visit to my brothers traveling through Northern South Carolina on back roads through small towns and two-lane roads I got 29MPG. The reason I think is because most back roads are long flat stretches of 45-55 MPH,

Speeds varied from 35MPH to 70MPH (for about 25 miles) Needless to say I'm impressed. I get 22MPG around town without much effort

The best I've seen

Wow... i'm jealous of you all.. I'm getting 17.1-17.5 pretty consistently. I drive 10 miles freeway to and from work every day and about 2miles city. Usually range 70-75mph on the freeway.

What octane gas are you using? Page 137 of the owners manual recommends 91+ for best performance. That's what I use and have never gotten less than 18.8mpg manually calculated. The dash has never shown less than 19.9mpg. I usually get between 22 and 27 with my FX4 Crew cab.

I see the same on 87. No reason to use 91 unless you're towing something up a mountain.

I see a lot of us manually check the MPG. Are you using an APP or stubby pencil? I use Fuel Monitor App but I am always look for a better idea.

It takes a couple of tanks for the computer to fully adjust to the higher octane. It will adjust to lower octane almost immediately when it detects knocking/ pinging. At higher elevations like in the mountains you can actually use lower octane. That's why regular unleaded in higher elevation states like Colorado is only 85 octane and mid grade is 87.

yes, you should plan ahead.

That's true for carborated + naturally aspirated engines due to there being less air. It's not so true for modern turbocharged engines (which are boosting more and therefore running much hotter under load at altitude). Modern naturally aspirated engines with fuel injection tune their air/fuel more precisely, and may not be happy with lower octane fuel, either. The anti-knock sensors should prevent damage, but you'll lose power. Note that the tests that said it was ok to drop a couple of octane in colorado were done on cars from the 60s...

I only drive from home to work most days that is just 5 miles away. I get about 20.

I did take a 1.5 hour trek up the road and back last weekend. I got just at 20 mpg highway. I was a little upset about that. It does give me hope that it will get better. Only at 900 miles still.

When I drove it home from the dealer, the dash showed me getting around 26.5 on the freeway. I was rather encouraged by that and then it kept dropping. Hopefully it gets back to that point.

I'm using Regular here in CA. This is one of the reasons I traded in my QX60 for this car was better MPG and could use cheaper gas. But it's not working out so far. My QX60 was getting 18.5 on premium.

I filled up in Urbana last Friday, drove to Effingham, around 80 miles, ran 75, had a little head wind and wound up with 22.8 mpg according too the truck computer. Now a week later and still on that tank the average for that tank is down to 21.4. At 1023 miles total for the truck, it says 20.6 mpg. I hope it goes up but still tops my old Dakota that got 13-14.

Long division. Learned it in school a LONG time ago

My first tank was 23.4 mixed driving on the computer and about 1 mpg less hand calculated. 2wd Lariat scab.
