Bringing back an old post...
I've noticed my gas mileage improving as well. But first...
I drive a 1997 Boxster, so I know many of you have a more powerful engine and different efficiency, but...
My daily driving is about 70% highway 30% city driving. Occasionally it will get closer to 50/50, rarely does is see more than 70% highway time.
I tend to accelerate moderately, get up to speed and cruise just at or slightly above the speed limit (posted 65mph). What is moderate acceleration? I typically shift just before it gets to be really "fun", say above 4500 RPM. Yes I know....that's why I define this a "moderate" as opposed to hard acceleration. At least once a week I will tickle the red line. It's a semi-daily driver.
Ok, now my baseline is out of the way....
I typically have been seeing 25.5mpg average on the tank and often up to 27.5. However, recently I've notice the milage has been ticking upward tank after tank. In fact, I have just a bit more than 1/4 tank remaining and I'm looking at 28.9mpg!
That's NUTS!!
As a result, owning this car seems a bit like cheating because I've got the cake and now I'm eating it!!
Now for a question....
Is the increase in mileage indicative of winter blend gas? Don't think so...shouldn't it work the other way around (summer/winter)? I still use the AC at times in the late afternoon. I live in AZ.
Thoughts?
