Just to let you know... With my brand new xA RS2.0 I have set new MPG challenges for myself, and since we have the same car I started what I like to call:
"The NeilBlanchard Challenge"
I'm going to try to beat (or even get close to) your MPG, which will be quite hard since I deliver pizzas, so all my trip are 3 miles here, 3 miles back, 4 miles there, 4 miles back, all stop and go city trash.
--I do have a question for you, do you wait until your "cold oil" light goes off before you drive or do you just crank and set off immediately? I've been doing half and half.
