I have a 2016 Chevy Spark that can hold up to 9 gallons of gas. I bought the car in 2016 and typically after I fuel up the display next to my speedometer will say between 335 and 355 (37-39 miles per gallon).
I got my oil changed, got four new tires and they did an induction cleaning and a coolant flush.
The next time I got gas, the display read 305 despite the fact that the tank should have been full. I had to drive a long distance and later that day I got gas again and the display then read 268. This has happened several times now.
The weather change has not been extreme. I am now getting significantly less miles per gallon on the highway than before my visit to get my oil changed etc. I am asking for advice on what could have happened to create this issue.
