Just filled up (12.6gal) and hand calculated 29.5 mpg over 350mi. Previous three fills from the same station (regular gas) were 27.0, 27.5, 29.0 in that order! Don't know how long this roll is going to continue, but I definitely like it ! Total miles just broke 5300.

EDIT: Oops, the miles for the fill was actually 373, not 350. I had to go back and check my records when it was pointed out my mpg calculation was wrong. Also, the mpg should have been 29.6, not 29.5. So much for me remembering the numbers from one room to the next !

 

My MPG has been TERRIBLE all summer since I started a coop close-by. Only short <1mile freeway runs and the MPG has tanked... Down to 24-26, lowest I ever had.

Last summer, I had 27-31 average. I miss those days!

 

Mm... Good MPG. I think I'm gonna do the same thing and see how much MPG I get. Does having CAI help or not with MPG. What about regular. Plus or premium help?

 

cool i get like 17-21 mpg :fml:

 

i feel your pain.

 

x3 ^^. and we need a :fml: icon. maybe even a :fyl:
icon devs, where are you?

 

I average 27mpg.

 

Wait till the winter blend gas arrives...

 

Will that work?

 

CAI makes no inherent difference, but if you have a heavy foot with the stock intake, the same foot will hurt MPG with a CAI -- it comes down to how you drive. Higher than 87 octane makes no difference either -- our engine tuning isn't designed to benefit (that's me using mine as a test case). Course, if you're running FI, then you've no choice but to be burning Premium -- the engine tuning is different and Premium is required to prevent detonation.

I've read an ethanol fuel mix can make a difference in the wrong direction, but I've no experience with it. If you buy fuel in the morning when it's coolest in the underground tank, it can help because the fuel is more dense when cooler, but I always get mine late afternoon.

 

Yeah, I expect either cooler weather or the winter mix (or both) is going to push it down again ! But it sure is nice while it lasts ! I just now changed to a thinner engine lube, and so that may help further with the next fill. That would be fun to break 30mpg -- I'll find out in about a month.

 

30 mpg is do-able with the xb2 (Ive done it). The problem is you have to be going 60 mph or less lol. Damn you Toyota for not giving us a tall 6th gear!

 

Welcome to all tC owners ever...

lmao. for now, yes.

 

I hate to ____ in your Cheerios here, but your actual MPG's based on your numbers is 27.7mpg, still respectable but not the 29.5mpg you posted.

Best way to calculate MPG's miles divided by gallons used to fill up. In your case it equals 27.7

And yes, winter blend will take toll on your mpg's.

 

Sorry about that, I accidentally entered the wrong number of miles. Here is the first post as I just edited it:

 

My xB lies to me. The digi reads 28.1 , but by my calculations it's only 25.4.

 

what i found out on saving gas was running the speed limit , driving to school tried to keep the car at 45 and gained .2 miles per gallon in 15 min. just think if you do that every day all the time.

we had 24.4 then went up to 24.6

 

My last two tanks were 23.88 and 23.92.
