I've given up on 30mpg

No silly the oil breaks down and looses it's slipperyness and the friction in the engine goes up and so does the wear - use better oil!!
I pumped my tires up to 40psi front and rear - yup the mileage when up some more - I gotta wonder what these tire manufacturer are doing to tires to make them so fuel consuming.

Change the oil and filter as recommended. Dirty oil is thick and causes extra friction between the moving parts; cutting efficiency and increasing wear. Use a "Energy Conserving" type motor oil.

Oil does not wear out, breakdown or otherwise deteriorate to such an extent that it needs to be changed. It becomes contaminated with water, acids, carbon particles and sludge. The engine's oil filter(s) can only remove solid particles above a certain size. It (they) cannot remove water, acids, carbon particles or sludge all of which pass through the filter(s) just as readily as the oil.

Because our motor oil is opaque black, it is DIRTY from the very start, and it stays that way, while protecting your engine, improving fuel economy, reducing engine wear, and giving you better, smoother and quieter performance!... Not a single ... TOYOTA vehicle that was converted to SynLube™ Lube-4-Life® when new or at low mileage had ANY lubricant related problems... and some of them now have over 102,000 miles without oil changes, and only one oil filter change.

ok here's something totally different thrown out there, I had to change my air filter (32,000 miles + construction everywhere, that thing has to be dirty) so I looked and said to myself... self... everyone rants about K&N, get one of their and spend the extra money. One dude even told me his millage improved. Is this true?

SynLube would probably come closer to converting me if they didn't have a website that looks like it was designed in 1990.
Interesting info there though. I used to be a duralube loyalist and never had any problems. But i'd always been under the impression that if you switched to an ultra slippery oil substitute before the engine was actually broken in that you did more harm than good when it came to emissions and power.

Get some fresh oil between your fingers and some with 5000 miles on it and tell me which one is slippery and thicker.
The Synlube is a solid lubricant of colloidal particals that seal the cylinders and rings better reducing blowby and friction even when starting with no oil pressure. They have a much better oil filter also to keep it clean with the graphite absorbing water until it gets hot enough to boil off and evaporate back into the PCV valve.
Usually there are zinc electrodes in the oil filters to neutralize the acids in the water contaminating the oil.
So far I have 11,144 miles on my xB with about 7500 on the Synlube and it is working just fine.

Also over-under inflation causes premature tire wear, so even if they don't care about the saftey because they want to save a few bucks on gas they will end up buying tires more frequent unless they like driving on slicks (which cause more rolling resitance killing more gas mileage)!

I drove my xB from Austin to Phoenix and back for xMas. The trip is a bit over 1000 miles one way.
On the way there I got 26.8 MPG.
On the way back I got 26.7 MPG.
The entire trip is on I10 (highway miles). I drive the speed limit both ways, but to be fair a good part of that is 80 MPH. The xB drinks gas pretty good at 80 MPH with an uphill...
Tires are at 30 PSI cold with a very good gauge.

Next time with the xB, hold a steady 60. And don't get on and off the throttle to hold 60 -- make no throttle changes.
On two trips like that with my manual xB, I got 42 mpg.
The xB is a gas miser at 60.

Yeah what Vintage42 says - I get 26mpg for the first mile when it is 28 degrees out and the engine is cold. Todays driving 69 miles of several trips was 47.3mpg - tank average 43.4mpg with a lot of little 1 mile trips that is dragging it down.
