New 2010 Yaris average MPG

[mtlguy]

Hi,
I purchased a 2010 Yaris sedan with 5,000 kms (3000 miles). The car still has that new car smell. It was bought from an old man and hasn't been on the road very much.

My first tank, I got 32 mpg (all city driving with a light foot)
On my second tank, I used Petro Canada and I got 30 mpg.

I think I won't be filling up at Petro Canada anymore.

Has anyone here used Shell V-power? I heard it's 100% gas (where as p.c. is probably 85%)

Thanks
