The Ultimate MPG thread.
#901
Bought a 2.7 Supercrew 2WD with tow package. Got 22.3 MPG city per the computer , 22.245 hand calculated. I currently live in San Antonio. Took it on a trip to Waco today and was only getting 22.5, but there was mixed driving results. On the way back about an hour outside of San Antonio, kids had to use bathroom so the Wife filled it up, I forgot to hand calculate it. But after driving the final hour to my home the computer shows 27.4..... at one point I had 28......, albeit I'm trying to see how high I can get it and I'm in flat land so its not a realistic expectation for most..... But I'm loving it.
Bought truck new at 622 miles on ODO.... Currently has 1300'ish

Not sure if it is a gas quality issue or not. I've bought gas from Sam's Club and QT. Maybe I need buy a better grade of gas from Exxon/Mobil, Valero, Shell or something like that. If you're doing something else, I'd like to know what it is. Any feedback is appreciated.

I was going to make a new thread but this is pretty related. I've got a 2015 3.5EB...I've been getting about 19mpg for mixed driving average. At some point I plan on getting larger tires for the stock 20's (275/55/20). Assuming I go up to a 33-34" tire (275/60-65/20)...What mpg should I plan on losing?

I've done 1200 miles with my 2016 157" wb 2.7EB SuperCrew (3.31 gear) since late January. The first two tanks came in at 21.5 on the lie-o-meter, with the current tank showing 20.9.
87 octane.

Finally, does anyone occasionally use Lucas Oil Injector Cleaner or Marvel Mystery oil additives to their gas to help bump up mpg's? Any pro or con issues?
I am STILL mystified how the other guy from Texas around the San Antonio area got the mpg's he posted not too long ago! I made the round trip drive (300 miles one way) between Dallas and San Antonio and did not come close to the mpg's he says he got!
My regrets if any of these questions have been asked before. Thanks for your patience and any feedback about any of this.

I filled up at Shell the other day and was talking to the owner. He said right now Shell is A ++. Exxon A+ and BP A. Just about every other brand is tier 2 gas ex: Costco,Gulf etc. When I got back in truck my MTE was 488 which was highest as of yet. Must be some truth to it since I started using better quakity gas I have been getting 21-22 mpg

As an update, I switched to non-LRR Goodyear Wrangler All-Terrain Adventure tires because I had frequent flats with the OEMs. Mileage in my 3.7L 2012 RCSB dropped from about 20-21 to 18.5-19.5 (at least during the colder months, up to 20 in the summer). I do a lot of highway driving at 70+ mph.
