Anyone gets >40mpg consistently in his/her xb?

Well Shell happens to be the most common place to fill up that is not 711 (Citgo) or Sheetz. I swear those places have terrible gas.
There are only a couple BPs and Sunocos. I've only seen one Valero in my life!

Where did you get that stuff to block your grille?

I've mentioned it elsewhere, but I got my coroplast at a local sign shop. They gave me a couple of misprinted election signs, and some other miscellaneous scraps. I offered to pay for them, and they said, 'don't worry about it, just remember where you got it from,' and sent me on my way.

I may go back to them to buy a full sheet or two in the future, however, as I plan to surreptitiously aeromod my girlfriend's Intrepid, and make a rear-end pan for my xB.

Yeah I need to find some of this stuff. I take it it's heat and water resistant?

[whokilledthejams]

Water, yes. Heat, I'm not certain. I have some pretty close to my engine, but not in contact with it, and none close to my exhaust. In the Scion xA aeromod thread, NeilBlanchard posted pics of a rear-undertray on his xA, and I just asked about how it's holding up around the muffler. If it doesn't melt or start on fire under his car, he may be on to something.

Your last tank was better than mine, nice job.
My next tank should be pretty awesome, you just wait.

So where can pick up some of this material? Lowe's or Home Depot I'm guessing?

Yeah something fairly heat-retardant would definitely be effective.
All the air passing under the car may help keep it a little cool.

Like I said, I got mine at a sign shop. Others here have mentioned buying full sheets of it at sign shops, too.

Also, It's probably best to keep it away from exhaust pipes, particularly near the front of the car. Apparently, it'll do ok at the rear as long as it's not directly touching the exhaust pipe.

Someone mentioned too high temperature in catalyst converter is not good, even it doesn't melt the coroplast. Must be very careful to cover the bottom....

[Z man]

I don't know of any sign shops.

But any undertray should be a benefit.

Hmmm.



We should post some xB pics!
I will have some soon.

Another 43mpg today!!! Without major aero mod (only lower grille blocked), it is pretty good. SGII is still in calibration. Now is 5% overrated, which is pretty closed. Next tank, I will try turning off engine in long traffic light (e.g. 3 way) See how it affects mpg. Since I drive 80% freeway, I don't think it will increase mpg a lot, hopefully, to 44mpg. I will install the shock this weekend.

Wow, 80% freeway? I'm lucky to get 50%!

But you have much more traffic over there, haha.

I can't believe I was at 260 miles at the half mark and only hit 43mpg?
