Gas Saving Tune Ups – Today’s Tune Ups have changed.
So what are Tune Ups, and do I really need them?
The short answer is no, you probably don’t need a Tune Up. Many years ago there were a lot of parts that needed attention quite often. We use to have a “spring tune up, and a fall tune up. That was because some of the ignition parts would be wore out in 6 months or less. They used to put lead in the gasoline that we used. That left lead deposits on the spark plugs, so they needed to be cleaned or replaced. There used to be a set of contact points that would open and close thousands of times in just one mile. Eventually they would wear out and need to be replaced. The fact is, you were lucky to make more than 10 or 12,000 mile without having to get a tune up.
So what do I need to do now?
Well we we don’t have contact points, or many other parts that we used to replace twice a year. We do still have spark plugs, but we don’t have lead in the fuel anymore. the spark plugs are made to last for up to 100,000 miles, so they don’t need to be changed often.
But we still have to deal with dirty air filters, and clogged fuel injectors. Things like throttle bores need to be cleaned from time to time. Some time the mass air flow sensor also needs attention.
Battery cables and connections still need to be cleaned. Fuel injection systems still need to be cleaned from time to time. Worn drive belts should be replaced as well as bad radiator hoses.
The short story is you probably don’t need a “Tune Up”. But you still need to have your engine serviced if you want to have a smooth running, dependable car.
