Distance 282.2 mi.
Fill amount 5.086 US gal
MPG Details 55.49 US

Pumped tires up a bit more, running them at 47 - 49 psi warm which is like 46 psi cold, 2 psi above sidewall rating.

Also have a pexiglass lower grill block that has been showing a good 1 - 2 mpg improvement. I plan to replace it with a better looking and more sturdy version and will document that on here when I get around to doing it.

Started my tank out on Sunday morning after I filled up at my local gas station. With good weather and no traffic, did 42 mph the majority of the way to work. From the gas station to work (35 miles) I had an average of 58.1 mpg, on the trip home (slighly more uphill) it dropped to 57.4 mpg.

With such a good start I tried to push it for the hole tank but drizzle and slightly more traffic for the next 2 days had me pick up my speed to about 48 mph and drop my mpg down to 55.1 mpg.

Fourth day was clear so I was able on my last round trip to and from work to bump it back up to the 55.49 mpg I ended it at.

Would have liked to have made it a propper 500+ mile tank but heading across state tomorrow for a wedding and I wanted a seporate consumption report for that round trip so I ended my tank early.

Was also able to obtain a 3 tank average of above 50 mpg and continue to hold it through 2 more fill ups.

My 5 tank average is 51.786 mpg.

I don't expect to hold it with this trip coming up but in the meantime....go Team Chevy!!!
