Made a couple of regularly made trips last week to find my mileage was cut down to about 8 mpg. Started to think about a major tune up, all night long figure and prices rolling through my brain
...woke up to run an errand and my right rear tire was squatting pretty bad...no air pressure at all
Spent a couple of quality hours at Discount tire, drinking free coffee, and !voila! Back to my wonderful 16-19 mpg!
