Default FYI after new Spark Plug & Intake Cleaned

Ok Folks, I replaced the spark plug with OEM and cleaned the Throttle Intake. I got approx. 100 miles with 4.45 gallons of Mobile gas. 50/50 Highway/City driving in Socal. Yeahhh Filled and Divided method here folks. Was averaging 17-18 mpg combined. The computer was showing 24.8 mpg after 3 minutes of cruising on the freeway @ 76 MPH and above. The mechanic haven't touch the MAF yet. The throttle intake was dirty, not too bad but was dirty. I was there the whole time when the Technician was cleaning it. Also got the tranny flushed with new fluid.

The gas tank capacity is about 19 gallons. Take your 300 miles/gallons you have pumped and get the difference.

Most manufactures aim for exactly this. 3 gallons left when the fuel light turns on. Due to the inaccuracies of most fuel gauges often they miss this mark
