Question about 2006 Scion xB

1 Answer

A few questions

I have had my XB for about 4 months now. I've been averaging 32 mpg but recently, when i got my oil changed my oil filter came off as i drove away. The mechanic said he fixed the problem but since then the car hasn't driven the same. Maybe i'm just paranoid but these are the problems:
1. It is idleing at about 500 RPM. Seems really low.
2. I was getting an average of 340 miles on one tank. Now I average 310-320.
3. Most my miles are on the freeway and i usually go about 80 but now it seems that the engine is working too hard. The RPM's are the same, about 4000 but the sound is different.

Any ideas/solutions?

I have a 2009 Ford Focus, I keep an eye on the little light that tells me what my average miles per gallon is. It usually stays in the 30 to 32 mgp range but yesterday I noticed that it had dropped to 28...

The most likely problem is that the gas you bought most recently was a "summer blend" designed to give you LESS MPG! That's because the companies want more profits, NOT better fuel economy, which would give those companies LESS profits instead of MORE profits!

Burning too much gas

the only true way to check fuel economy is to fill tank drive till 1/4 full do this 10 times taking your milage reading before each refill
that will give you your average milage
now if you live in a hilly area and your up and down all the time that will also throw all stuff out the window and in order to get what the manufacturer suggests vehicle will do for avg milage is to go at a steady 30mph on a very slight banked oval tack that is basically flat That is how manufacturers of vehicles get the milage a vehicle will go per gallon

MPG has dropped

Air filter? And any car I have ever owned with a timing belt has shown a noticeable drop-off in MPG when the belt had some miles on it. I would do what you have done but added (or at least eyeballed) the air filter. If that didn't bring it back, the timing belt was next since it doesn't take hardly any stretching to throw off the valve timing and it is critical to performance and MPG.

I usually get 30-32 mpg and now I am getting 27. Why?

Has there been any changes to your vehicle in the last few weeks that you can recall. Regular oil changes are a must. Also, check the air pressure in your tires every once in awhile. These two things are key to keeping your car running good and getting better gas mileage. Your tires will also last longer if they are at the propper PSI. Also, do you travel the same route every day or does it change. Highway driving and city driving have a big difference in the average fuel economy your vehicle is going to get.

High gas mileage (15- 20 l per 100km)

try changing the oil also it will cause the engine to burn more fuel with bad oil because it gets hot and evaporates it alot more

15 mpg 2006 honda accord I4 auto. in city driving is this normal?

Doubtful. The K&N air filter is an aftermarket part which isn't compliant with standard factory parts against which those recommended MPG are tested.

The tyre pressure sounds too high for a car that size also, it would be worth enquiring with a main dealer what the reccomended pressure is.

Also your own driving ability comes into equasion too. Heavy/constant braking can affect it, having the air con witched on affects it etc etc.

All of the above combined would make a pretty big difference to your MPG.

Hello woodmanz,
Thinks that help mpg.
Change air filter, engine needs oxygen.
If using air conditioner, try with it turned off?
Oil change helps if has not been done.
Air in the tires help with mpg.
Tune-up( spark plugs,etc.
