ok so i am not complaning about having great MPG lol

but im curious could any of these reasons be actual reasons for why the MPG has spiked so high i mean like really

for the first year i owned the ES 07 i drove around 35k was always getting like 26mpg highway 18 or 19 city

about 2 months ago I took the car in for fuel injection cleaning
Miles Spike up a little bit i started noticing when i would fill up less on road trips or at-least the dummy warning system would tell me i was getting better MPG

then i stopped going to the dealer for oil changes started going to tire kingdom noticed MPG got even better after switching oils this one i know i just can't believe but im not going to discard that posabiliyt of that being why
so after the first 2 steps and then the air filter replacement i started noticing around 28mpg highway 20 mpg city

now after 4 new struts and some other steering and suspension components my last trip to tampa same driving conditions as before
Cruise Control set between 67 to 70 mph
i was getting 31 mpg i thought at first that it was just the AVG MPG telling me something and didn't think anything of it
but when i went to pump gas after driving 341 miles it only letting me pump just a tad over 11 gallons before the pump shut off and wouldn't take anymore gas in the tank i did the math
11 gallons of fuel used 341 miles driven
and thats more than i ever got before

So is this all a coincidence or are these reasons all enough to make it spike that high ?

Summer blend fuel makes a huge difference, but don't know if that applies to Florida! lol
