I thought I'd share some intriguing news. We just had the second customer this week bring their car by for work with the same issue...gas mileage. Seems their cars just don't go as far on $20 as they used to. Swear to God...they both came in..one on Monday and then just now a second customer. Same story...just wouldn't make it all week on $20 any more. Must be something wrong...

 

That's what they get for not driving to work downhill the entire way with a tail wind.

 

thats like to people that buy binoculars and return them because they make everything look far away..

 

Or the guy I saw returning a nice Echo chain saw at Home Depot. Whining how it just wouldn't cut. I couldn't help but notice...the chain was on backwards!

 

That might be a good time to give their cars a tune up, switch them to synthetic and sell them a K & N filter which would likely boost them 4 mpg.

 

I think Swiftjustice has too much of a conscience for unwarranted work...but that's a good idea!
If you claim to have made an adjustment or improvement, they would drive slower/ more efficiently, placebo effect.
