EAST PATCHOGUE, N.Y. -- Irv Gordon was a 25-year-old science teacher in 1966 when he bought a brand-new, cherry-red Volvo P1800. Today, Gordon, now retired, still owns the same Volvo. Last March, he put the 2 millionth mile on the car.
Gordon's vehicle hit the big 2 mil at a special televised ceremony held in Times Square in New York City. "It was incredibly exciting--totally beyond me," he told Current Science later from the mobile phone in his car.
To what does Gordon attribute his car's amazing longevity? "Volvos are very tough cars," he said. "Also, I'm not a hot-rodder; I drive sensibly. And I take very good care of the car."
Gordon changes the oil every 3,000 miles; uses only the same brand of oil; changes the spark plugs every 20,000 miles; washes the car regularly; waxes it at least twice a year; and spends a few minutes each week checking under the hood, among other things. "Being a science teacher, I have a better idea of the ways things work," he said.
Gordon says the vehicle still has many of its original parts. But many parts, such as the starter motor, the brakes, the water pump, the carburetor, and the clutch, have been rebuilt or replaced. (The carburetor controls the mixture of gas and air going to the engine. The clutch enables the driver to change gears.)
Oil Used: I read in another article that Irv uses ONLY Castrol 20w50
