'80 Cars Easier In 1930, Change of Oil Needed Every 500 Miles -»*1 - UiJAv. PAGE 13 • PLAINDEALER - FRIDAY, OCTOBER ». IMP By DAVID GILMORE Cars are being built to more exacting specifications but they actually are easier to maintain compared to their counterparts of 50 years ago. The automobile owner of 1930 was almost, by necessity, a do-it-yourselfer because of the need for frequent maintenance under the hood and a shortage -- in some sparsely populated areas, an absence -- of skilled mechanics. The 1980 automobile con­ tains between 15,000 and 20,000 parts, including 5,000 movable parts. Yet over its life­ time only about 100 non- maintenance parts will have to be replaced, says Tim Tierney, director of technical services for the Automotive Parts and Accessories Association. The 1980 General Motors car has only four grease fittings that need to be lubricated every 7,500 miles. By contrast, says Tierney, the 1930 Model A Ford had 31 grease fittings that had to be lubricated every 500 miles. The 1980 GM automobile re­ quires an oil change every 7,500 miles, and its oil filter needs to be replaced on every second oil change. Oil in the 1930 Ford had to be changed every 500 miles. The Model A had no filter to keep out dirt, which is why its oil had to be changed so often. The 1950 automobile wasn't much of an improvement. Its approximately 22 grease fit­ tings had to be lubricated every 1,000 miles and its oil changed every 2,000 miles. Electronic ignition on 1980 cars means there* are fewer items to change or check, Tierney says. Spark plugs should be replaced every 30,000 miles, a vast improve­ ment over 1950 models which required points and condensors to be replaced every 12,000 miles or annually. "Todayis cars don't need tuneups in the old sense of the word," Tierney says. "They need tuneups in the new sense of the word. That is, they need to be tuned for proper opera­ tion of the emissions control system. Their PCV valve (for positive crankcase ventilation), which is a part of the emission control system, needs to be checked regularly. "The timing also needs to be set properly for the air injec­ tion system and the exhaust gas recirculation system to func­ tion properly." Even so, the 1980 car needs less attention than the Model A. The owner of a 1930 Ford had to change the transmission and differential lubricant every 5,000 miles. The generator charging rate had to be,ad­ justed twice yearly for cold and warm weather, and the car­ buretor bowl required frequent cleaning because dirt and sedi­ ment collected there due to an absence of fuel filters. By comparison, the do-it- yourselfer of 1980, thanks to the use of filters and low- maintenance components, can keep his car in perfect condi­ tion with much less work. Technology is changing the modern automobile into, ,a more efficient machine, with U/HAT DOCS IT SAY ABOUT GETTING YDUfc FINGER advances coming in the form of electronic ignition, tur- bochargers and fuel-efficient diesel engines. Do-it- yourselfers are getting help however in understanding the maintenance needs of the new components through car-care clinics and a wide variety of in­ structional literature. And prospects are that motorists will be able to con­ tinue to save money regardless of the state of automobile technology. Electric vehicles, for exam­ ple, are expected to enter mass production in the mid-1980s, but they should prove no pro­ blem for the do-it-yourselfer. "With a Jew exceptions, maintenance of electric cars will be the same as for conven­ tional cars," says Tim Tierney, director of technical services for the Automotive Parts and Accessories Association (APAA.) The engines of electric cars will require little maintenance because they are cousins of the maintenance-free engines that power automatic washers and other appliances, Tierney says. Also missing will be radiators, carburetors and ignition systems. But other than that the maintenance of an electric car will be similar to today's cars. Electrics will have some sort of a drive shaft and differential mechanism, Tierney notes. Steering suspension, brakes, shock absorbers, lights, horns, windshield wipers and heaters are among components that you'll find on an electric vehi­ cle.

Custom Polvsteel...The Tire That Keeps Its Feet Even Iri The Rain! Double Life of Retailer No Secret What does a tire expert get that you don't? Well, for one thing, twice the tire life. Leroy Yancey, manager of a tire store in Cordele, Ga., reports getting 75,000 miles out of a set of tires having an ex­ pected tire life of 30,000 to 35,000 miles. The secrets to his success are not secrets, Yancey says. He believes in tire maintenance. That means checking air pressure once a week, and keeping wheels aligned and balanced. "Car owner* are told these tire tips again and again," the store manager says. "Those who listen and follow the ad­ vice can save a lot of money on their tires, alone. "Balance and alignment also will increase engine life." P?lb/75H15 WtttHwH MM I? 76 ftl • Mo Hide needed • (Alee Hi G*7i ib P70V7SH1& wmtewtH plot »?67 If!
