Motormouth: Keeping up with toll technology

Q: The Illinois Tollway recently announced that cash tolls will no longer be used. People who don’t have a transponder and/or out-of-staters must pay within 14 days. And they must figure out what they owe. My question: Why doesn’t the tollway use machines that accept credit cards? The whole world has come to accept credit and debit cards as a result of COVID. It would make life much easier.

A: The tollway system does accept credit cards, but not at toll booths, which are history. You don’t even have to sign up for a transponder. The tollway will bill you and send you an invoice (which you can pay online) if you set up a Pay-By-Plate account. Your license plate is read by a camera. I have a Pay-By-Plate account and live out of state (Virginia). My EZPass will also work.

Q: The fuel economy of my 2005 Subaru Outback 3.0-liter, 6-cylinder with 151,000 miles went from low 20s to not even in the teens. Mechanic friends are telling me it is the O2 sensor, which would mean about $800 in parts alone to replace four sensors. My Subaru dealer says it’s not the sensors because there is no check engine light. They are suggesting a tuneup to the tune of $400. The spark plugs may be 16 years old with over 151,000 miles on them. Is it possible new plugs would double my gas mileage? Were it not for the fact that I’ve spent over $1,600 on new tires and exhaust work less than six months ago, I would reluctantly sell the car.

A: As the dealer said, new oxygen sensors are not needed as even one bad one would trigger the check engine light. But it sounds like they are guessing by suggesting a tuneup. I have a hunch it would not help. Find a technician who knows how to interrogate the car using a scan tool and the knowledge to interpret what he sees.

Q: I read your column every week, and I am a retired auto tech. I took my 2017 Jeep Wrangler in for an oil change recently, and they did an inspection. They told me I needed rear brakes and wanted to charge me approximately $860. I bought a good set of rear pads for $67 and did it myself. Your readers should know that it is much cheaper and just as safe if you go to their local shop.

A: As a former ASE Certified Master Automobile Technician, I could not agree with you more. Choosing an independent repair shop may also help keep a small business alive.
