Gas Mileage Sanity Check

Just wanted to get some feedback from other members. I got an '09 Tacoma, just put flowmaster exhaust on it. I just put some bigger tires on, (nothing crazy because my truck is still stock...2756517's I believe). Somewhere in this process my gas mileage seems to have diminished. I just did a calculation with my last fill up and got about 305 miles on 17.2 gallons. Wanted to see how this ranks up with what other members on here are getting.

I know all of these topics usually boil down to basically tire pressure, clear air filters and checking for clogged exhaust. Not looking for tips on those things, basically just want to hear how this stacks up with what everyone else is getting.

 

My 12 is totally stock, running winterforce snowtires, getting between 19 and 21. No better no worse. Been butt cold here

 

305 on 17 gallons is better than I get. Tires and a flowmaster will definitely decrease your mileage.

 

You are getting better then my stock 12 dclb with factory 265-65s.

 

Have 265 on and a k&n and only get 14.5 in the winter

 

Same here. Drives me nuts

 

Last two tanks have been 20mpg for me, minimal 4x4 use. Some cold, some nice weather and a couple mountain trips.

 

Hand calculated 21 MPG. UG is +/- 1 MPG






​

 

Yes it sucks. But summer I get about 18.6

 

Brand new all stock dcsb off-road and only getting 16mpg... hoping when the summer blend is here I can squeeze out 18.

 

22 to 23 right now. All stock.

 

I have 600 miles on the truck so far and first tank was 16.5 mpg, second tank was 17.5.

I just put a K&N filter in, but I doubt that will change things significantly either way.

Heavier rims/tires WILL make a difference.

 

Thanks for all of the input everyone. I thought that intake and exhaust are supposed to increase your MPG???

 

They don't necessarily help you out. If you want better mileage get a Prius! Its a truck it won't get good mileage like they advertise.

 

So over played

 

They might not hurt your mpg but they don't increase your mpg.

Increased tire pressure helps.

 

so basically the only reason to add them is for slight to no power increase, and coolness...

 

When you lift the truck, you loose mileage.
When you change the tires to a slightly larger size, you loose mileage.

I noticed it right away. The stock rims are engineered for being at their
most aerodynamic with the stock tires, along with the gearing of the
tranny and the engine performance.

Changing the tires, takes the airflow, road resistance, and the engine
gearing out of the preset, optimum, performance.

Slight power maybe above 4000 rpm. Not where you get good mpg.

Coolness, no.

 

I get about 14. That's lifted, slightly bigger tires, exhaust, and intake. Put some H/T tires on it for mpg.
