#310 of 411 Corolla 5speed manual MPG

I agree - the manual is a bit better is seems on MPG. I have a 2006 toyota corolla 5speed. Long interstate drives I get about 37 to 38MPG while in the city I get about 31 to 33 MPG. I think this latter is a bit higher than EPA estimates which are probably automatic transmission numbers - I think it also helps in the city that I coast a lot with the clutch in if I see a stop coming up.

Wow! I bet you save on fuel with that method but really go thru the burned clutches, huh? Try using the engine for braking instead of coasting up to a stop with the clutch depressed and you'll not only save your clutch but your brake pads as well. Lets see, what cost more, a clutch, brake pads or gasoline?

The steering is a little weird but I have become used to it.

I have a similar issue with my 2007 LE. Within the first year of purchase I took it across country and logged about 42 MPG, and that was with the AC on much of the time. Needless to say I was thrilled. A year later I took it across country again, and I began to notice that the mileage was down by about 7 MPG or so. I even stopped at a dealership on the way because of this concern, who could not give me any reason for it. Air pressure was within acceptable limits.
My most recent highway trip yielded me around 29 MPG a few months ago. Toyota isn't interested in looking into this and they are acting clueless. I think the problem is probably more widespread than most people realize, and I have a sneaky suspicion that the problem involves the problematic PCM which I'm sure Toyota would prefer for that problem to just go away as they are going to wind up spending a fortune when they are forced to do a recall because of the safety issues.
I would love to see some people with this same problem all get together and put pressure on Toyota or some regulatory agency to have something done about this

What is a problematic PCM ?

That seems like a pretty dramatic fall off. I thought I had a similar thing with my 2006 corolla - when I first got it (used), thought I was getting about 39 to 41 on the highway. Immediately after putting on new Michelin tires, it dropped to about 36 to 38. Turns out the older tires were just worn and hence giving a shorter travel distance per revolution. This showed up in my MPG calculation as a longer distance than I was actually traveling (the odometer is counting revolutions not distance). For good MPG accuracy should calibrate your odometer to actual distance - I did this on the interstate by noting what my odometer read after travelling about 100miles by the mile markers on the side of the road. With the old tires, I am guessing that 100mile physical distance would have shown up on the odometer as something like 103 to 105. My new tires, incidentally, are a little "taller" (kind of odd terminology, but what the mechanics use for "diameter") and I have to adjust my reported miles up by 1.01X. I am getting 1% more actual distance per revolution than the odometer is expecting.
This is unlikely to account for all of the drop you are seeing, but something to consider.

More aggressive tread, ie M/S, and wider tires will not give as good mileage as narrower "Smoother" treaded tires.

Interesting, when the the PCM (whatever that is) become problematic? First I've heard ! Perhaps the time of year you took your second trip could have been a determining factor in your lower gas mileage. In the winter months in certain areas more additives are added to the gasoline which hurt gas mileage. Can't say I can fault Toyota for brushing you off regarding why your getting ONLY getting 35 mpg on the highway when you think you should be getting 42. Do ya think they got more important things to worry about ???????

I have a 04 Corolla base model with 70K miles and MPG is been great! Went to Vegas on Jan for CE show and averaged 44.78MPG. The trip was from Chula Vista to Las Vegas using almost all I15 and I drove around 70-75. PSI was 36-38. On normal daily use, we get 33-35MPG, and if we go to LA, there is a good chance getting close to 40MPG, if there is no traffic.
