context_page_description: Oldsmobile was a brand of American automobiles produced for most of its existence by General Motors. Olds Motor Vehicle Co. was founded by Ransom E. Olds in 1897. It produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory alone. During its time as a division of General Motors, it slotted into the middle of GM's five divisions, and was noted for its testing of groundbreaking technology and designs, most notably the "Rocket V8" engine. In 1985, over 1 million Oldsmobiles were sold, but by the 1990s the division was tasked with competing with import brands. When it was shut down in 2004, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Mercedes-Benz, Peugeot, Skoda, and Tatra.
context_section_description: The 1970s and 1980s were good years for the Oldsmobile division; sales soared (reaching an all-time high of 1,066,122 in 1985) based on popular designs, positive reviews from critics, and perceived quality and reliability, with the Cutlass series becoming North America's top selling car by 1976. By this time, Olds had displaced Pontiac and Plymouth as the third best-selling brand in the U.S. behind Chevrolet and Ford. In the late 1970s and again in the mid-1980s, model-year production topped one million units, something only Chevrolet and Ford had achieved.
  The very popularity of Oldsmobile's cars created a problem for the division in the late 1970s, however. At that time, each General Motors division produced its own V8 engines, and in 1977, Oldsmobile, Chevrolet, Pontiac, and Buick each produced a unique 350-cubic-inch displacement V8. It was during the 1977 model year that demand exceeded production capacity for the Oldsmobile V8 and as a result, Oldsmobile began equipping most full size Delta 88 models (those with Federal emissions specifications) with the Chevrolet 350 engine instead. Although it was widely debated whether there was a difference in quality or performance between the two engines, there was no question that the engines were different from one another. Many customers were loyal Oldsmobile buyers who specifically wanted the Rocket V8, and did not discover that their vehicle had the Chevrolet engine until they performed maintenance and discovered that purchased parts did not fit. This became a public relations nightmare for GM.
  Following this debacle, disclaimers stating that "Oldsmobiles are equipped with engines produced by various GM divisions" were tacked onto advertisements and sales literature; all other GM divisions followed suit. In addition, GM quickly stopped associating engines with particular divisions and to this day, all GM engines are produced by "GM Powertrain" (GMPT) and are called GM "Corporate" engines instead of GM "Division" engines. Although it was the popularity of the Oldsmobile division vehicles that prompted this change, declining sales of V8 engines would have made this change inevitable as all but the Chevrolet version of the 350-cubic-inch engine were eventually discontinued.
  Oldsmobile also introduced a 5.7L (350 cu-in) V8 diesel engine option on its Custom Cruiser, Delta 88 and 98 models in 1978; and a smaller 4.3L (260 cu-in) displacement V8 diesel on the 1979 Cutlass Salon and Cutlass Supreme/Cutlass Calais models. These were largely based on corresponding gasoline engines but with heavier duty cast blocks, redesigned heads and fast glow plugs; and on the 5.7L, oversized cranks, main bearings and wrist pins. There were several problems with these engines, including water and corrosion in the injectors (no water separator in the fuel line); paraffin clogging of fuel lines and filters in cold weather; reduced lubrication in the heads due to undersized oil galleys; head bolt failures; and the use of aluminum rockers and stanchions in the 4.3L V8 engines. While the 5.7L was also offered on various Buick, Cadillac, Chevrolet, GMC, and Pontiac models, it was eventually discontinued by all divisions in 1985. V6 diesels of 4.3L displacement were also offered between 1982 and 1985. In 1988 the then all-new 1988 Oldsmobile Cutlass Supreme Pace car was the 1st production car with heads up display. 
  Notable models:
  Oldsmobile Cutlass Supreme (1966–1997) – more performance and luxury than the lower priced Cutlass and Cutlass S models, fitting in at the lower end of the personal luxury car market. Models were similar to the Pontiac Grand Prix, Chevrolet Monte Carlo, and Buick Regal.
  Oldsmobile 88 (1949-1999) – Oldsmobile full-sized family coupe and sedan. Led Oldsmobile sales from 1950 to 1974. Downsized in 1977, became front-wheel-drive in 1986. The first-generation 88 is reputed to have inspired the song "Rocket 88" – arguably the first rock & roll record.
  Oldsmobile 98 (1941–1996) – Oldsmobile full-sized luxury coupe and sedan that was downsized in 1977 and 1985, became front-wheel-
