They're very accurate! There is a bit of adjustment but you just need to compare the SG tank versus the pump and input the change.

My SG1 was within a couple of percent of the mark at fill-up time, right out of the box. I just recently started using the correction factor to get it dialed in as close as possible.

They're also useful for showing you all kinds of info you can't get through your gauge cluster.

Welcome Schmeep - and keep working on that MPG because if you check out my gas log my mpg is climbing faster and I am running in a 2006 xB!

damn straight.

how about two really bad photos of my yaris?
well too bad, here they are anyway:

Looks a lot nicer than in the damn comercials! Looks ready for a grill block too, :p

can you put a grill block on the inside of the bumper?

Yes. But to be clear, it's not a radiator block you're after, but a way to prevent excess airflow from entering the engine compartment in the first place. So you'd want to block the rear of the grille.

is that easy to do? i'm not the handiest of fellers, but i can usually fumble my way around some DIY projects.

I would love to see some suggestions on this. :) I am currently on my best tank yet, hoping to come in at 41+. The new Yarii have been my inspiration.
