Here's a stupid one for you guys:

Is it normal for a wheel spacers to not fit flush against the wheel? I ordered a set of 11mm spacers from shopdap. The spacers fit flush against the wheel hub, and the wheels are secure against the lip of the spacer, however there's probably a 1mm gap between the spacer and the wheel.

Seems strange to me.

How accurate do you find your fuel consumption readings vs. a manual calculation? I honestly don't care too much about the absolute number, but I like to see the relative change based on how I drive. I haven't done a manual calculation with this car, but my wallet tells me it burns about 45% of the fuel my F150 does, which lines up with the display.

My Fords were all about 5% optimistic, Dodges about the same, GMs must have been using that new math, because they were all out by over 15%.
I did the math when I filled up today, and the displayed fuel economy was out by less than 4% on the 'Since Refuel(?)' calculation. Good enough for me.

What could cause a spark plug gap to close? I replaced a set of Ruth's that had maybe 15k miles on them, and the gap had closed to ~0.020 or so. When I installed them, they were pre-gapped to 0.024 - 0.025 (same as the new ones), and I had left them as-is. Usually they open after time, not close...

Maybe they are for Australian models?

I've not heard of that either.

That’s impossible. Shouldn’t it widen little by little?!

:) I only asked because I wasn't smart enough to check behind the manufacturer the first time I purchased pre-gapped plugs.
The Ruthenium plugs come pre-gapped to 032. He gapped his to 024 and after 15,000 miles the gap had tightened. Plugs always open up the gap after some mileage.

You confirmed this?

Yes, I distinctly remember checking them when I got them. Both sets, the old and the one new today, were pre-gapped around 0.024 - 0.026. Gap wasn't touched on either set.

These are both old ones. The one on the right, I opened the gap to ~0.024 for comparison. The one on the left, I can barely check with my gap tool which starts at ~0.020 (one of those metal circular ones the size of a half dollar):
