Ok well here is an update....
I drove from austin to houston and i got about 115 miles from a quarter tank....averaging about 75-80 miles on the highway....so I am confused now...

 

i once got 620 KM or about 380 miles to a tank, that was doing 70 MPH in optimal weather (wind slightly at the back, 15 degrees).

and now i get 480 km to a tank thats about 290 miles and i fill up about 55 litres (about 15 gallons) O ya, and they tax gas in canada, soooooooooooo I pay way more then pretty much all of you at about 60 bucks for 14.5 gallons for premium fuel (91 octane). Essentially I pay 4 dollars a gallon, and my currency is almost on par with yours (american), my country is also a huge producer of oil (canada)

/thread, no complaints from anyone else.

 

yea my buddy told me about seafoam.. but Thinner based in oil sump idk.. product actually works but im not gana be the ginny pig to try it on my G

 

Exactly! OP... be glad you don't live in the UK, other parts of Europe where you can pay close to $8/gallon. We have it lucky in the states.

 

+1 i was just in norway over summer and paid nearly $12.50 a gallon, believe me, we walked a LOT

 

Just finished a tank of gas... 2 trips on the highway, roughly 55 miles round trip for both.. I squeezed 14.5 MPG out of this tank.

 

i usualy get 14-15 in the city and 20-21 on the hwy
