MPG After 1 year by joeben

I have not been able to exceed 25 MPG highway. I went to my dealer/service dept and inquired. I mentioned that my last oil change was done with 10w30 in the middle of summer. He recommended sticking with the 5w20 factory recommended viscosity, even in the 100+ degree summers of Texas. Will let you know if this makes a difference.

What sort of driving were you doing to get the 33MPG?

The best I have done was 6.3L/100Km (44MPG imp- 37 MPG us gallon) at 90km/h (3.5 hour trip 17C). The average I get with mixed 60% city and 40% highway (130km ) is 10L/100Km (28.25 imperial 23.52 US gallon). The biggest hit is due to the city driving. Ever since they “dumbed” down the transmission with the “fire” fix they put a delay in the shifting. You probably notice this when if you are slowing down and then need to accelerate and nothing for a second then clunk it goes. You will notice that it takes longer for it to shift down (i.e. from 3 to 2) a gear unless you press excessively on the gas pedal. It is a shame I do like the car but loved it even more before they messed up the transmission.

What sort of driving conditions gave you the 37mpg? Was is 100% highway on a long flat road driving about 65mph on cruise?

Hey bob. 90km/h is roughly 55m/h. It was a B road. Not a major highway - 1 lane each way mostly empty road (yes it is a fairly long road approx 300km (~190 miles). The road was fairly flat with little wind. A/c was not needed. Cruise control was on as I am a bit of speed freak normally. :$

its the other way round i blve. the higher the firnal gear ratio, the faster the engine revs for the same road speed.

i did my first oil change on my mazda5 5speed at 4K miles. put in 5w30 since i had a case of that left over. the mileage dropped from 26.5 to 23.5. double checked it over several fillups and it was steady at 23.5. drained the oil and switched back to 5w20 at 5200miles. never seen this before!

One 330 mile drive on a relatively flat freeway with the cruise set at 65. Took exactly 10.0 gallons to refill it.

I have 2400 MI. on a 2007 Touring automatic model. I drive ok, no grandma driving or crazy driving. I drive mostly freeway in heavy stop and go traffic. I am on the fast side when traffic allows getting to 75 MPH. So far over the entire span of 2400 MI I have averaged 27 MPG with my automatic. My first couple tanks weren't very good. I found my tires were about 6-8 LBS low from the dealer showroom floor. Also I found with the air on gas mileage drops 2-3 MPG. I have auto climate control. I turn it on auto and push the air to shut it off. Granted I haven't driven in the summer with it yet.
