Hey everyone,
I have an S10 pickup truck with 5 speed and a 2.2L 4-cylinder.
I had a fiberglass cap on it for running around with my work gear to keep it safe and dry.
My previous tank, I have the cap on there half the time, the other half, I had it off for carrying the motorcycle to various events.
This past weekend, I had the cap off, and went camping and took the cycle to an EVent.
The previous tank, with the cap on half the time, I got just under 23 MPG. My immediately last tank, pulling the trailer half the time, got just over 26 MPG.
Temperature was pretty similar between these two tanks of gas. I did a better job at keeping a slower speed on the freeway on my last tank.
Still suprising that I got better economy pulling a brick of a trailer down the road.
