Yeah thats darn good. Think thats 5.8 in L/100km.

What speed were you doing if you dont mind me asking?

On my stock ST I'm doing 39mpg on the flat at a steady 65mph. If I push onwards to 82mph I'm doing 33mpg.

I'm getting right at 35mpg at 73mph on the interstate....flatlands.

I get 28 avg. 22 miles each way, 10 of it freeway and 12 stop and go traffic city tragic that takes about 40-45 minutes total each way. Still it's not bad and always fun.

After two fuel ups, I averaged 29 mpg.

I drive about 40 miles a day with 30 of those miles on the highway at 75 mph.

It would also be interesting to know what grade of fuel everyone uses. I put 91 octane in my tank running all stock.

93 octane with Cobb stage 1 tune. Lifetime average over 23000 miles is 31.4 with about 70% highway.
