Incredible MPG

3 posts in this topic

Greetings All,

Well, It's been 6 months since purchasing my 2019 Spark LT.  Thought I'd share some great news (in my book).

In this forum I read that for the best miles per gallon rating, one should use 85 octane after breaking in the

engine @2,000 miles or so.  Well, that I did and following is my record for the last 4 fill-ups plur the current

stats.

04-01-19:   45.1 ave. mpg @ 3,314 total miles  (This was my first tank of 85 octane)

04-19-19    47.4 ave. mpg @ 3,630 total miles

05-07-19    47.8 ave. mpg @ 4,021 total miles

05-25-19    46.6 ave. mpg @ 4,359 total miles (Chevy service crew brought the average WAY down)

06-02-19    48.0 ave. mpg @ 4,552 total miles (As it sits right now in my driveway)

And about the service, I kept hearing a small "clanking" noise from the rear passenger side.  Of course, whenever

I brought it in, (3 times) we were unable to get the noise back.  So I recorded the noise with a little digital unit

and the 4th time I brought the Spark in, I just played the recorded "clank".  In 15 minutes, they found the spare

tire was not firmly firmly seated.  They corrected same, and I have had no repeat.

Those numbers seem really off. How are you calculating your mpg? And do you do any in town driving?

For best performance and fuel economy you should run what the manufacturer recommends. Running 85 octane fuel is not recommended. Read the book.
