I used to get 27mpg on the highway with regular. I put in techron fuel injector cleaner and started using super.

What else can I do to increase fuel economy? Spark plugs?

yep.. spark plugs are good idea... looks like u need them anyway since u have a little more than 100K miles. Fuel filter too if it was a while since u replaced it. And do your car a favor don't put regular gas in it. U don't save a lot of money by doing so.

Yea. I was too cheap at the time. I like the car with super.

It's also because of the wheels. Change the spark plugs if needed and maybe the boots (they will most likely be cracked)

 

[zhenkaaaM3]

yes,the wheels are amazing :thumbsup: idk if needed. I do not know of maintenance work of previous owner. I want to start a clean slate.

Yup.

Btw we have like the same mileage.

Make sure your tire pressure is at least at the recommended level, I personally run a few pounds more.

Less rolling resistance.

 

[zhenkaaaM3]

thats weird, considering my car is 2 years older. But its all good. I am lacking a torque wrench and that long extension you showed in the vid.
