CAR QUESTIONS TAKEN FROM
OUR WEEKLY TALK RADIO SHOW
Dear Motor Medics,
I drive a 2000 Chevrolet Silverado truck with a V8 engine and 4 wheel drive. I think the fuel mileage is much less than it should be getting. At this time my combined city/highway driving is only about 14 mpg. Recently on your car-talk show and in your column you mentioned a fuel system cleaner that will help get better mileage. Is it something I can just pour in the tank and fix my problem or something more involved?
Thank you, Duane in Youngstown Ohio
What we often talk about on our radio show is a professional fuel system or induction system cleaning. A shop that specializes in the system service will connect a machine to the engine fuel rail and use a chemical to clean the injection and the combustion chambers and the intake which in turn brings back lost engine efficiency that has been lost to carbon build-up. The pour-in tank products are great for maintaining the engine between cleanings but will not clean like the professional system. Think of it like a teeth cleaning, brushing alone won’t get the job done. The cleaning will only help mileage if it has been reduced due to a build-up in the engine. Your mileage compares to other well running trucks so at this time you may not be helped by a cleaning. Remember to check things like your air filter and tire pressures as well and avoid jack rabbit starts to increase your mileage.
Take care, the Motor Medics
