EALER GEOFFREY AITCHISON of New Tecumseth, Ontario passed his 1985 Jetta Turbo Diesel to his daughter, Marianne, when she graduated from high school. Aitchison became a Dealer in 1982, so he installed AMSOIL products in the Jetta when he first bought it. When Marianne took over the vehicle, it had 565,000 kilometers (more than 350,000 miles) on it. “She drove it to school, on trips and to her job,” he said. She married, had four children and made several trips to Florida in the Jetta.

The odometer finally quit at 921,000 kilometers (about 572,000 miles). The car was driven for another two years, and Aitchison believes it surpassed 1,000,000 kilometers. In 2004, the car was sold for parts because the sunroof “had become a sieve and the electrical system went to shambles,” Aitchison said. “However, the engine still started and ran perfectly.” Aitchison updated AMSOIL products in the vehicle as they became available.

Initially, he installed AMSOIL 15W-40 Synthetic Diesel and Marine Oil (AME) in the engine and 75W-90 gear lube in the transmission. He changed to AMSOIL 75W-90 Long Life Synthetic Gear Lube(FGR) when it became available. The oil filter was an ASF-15, changed twice a year, along with an old-style canister by-pass system. An AMSOIL wet-type air filter was fitted. Diesel Modifier was used continuously, along with Cetane Boost (ACB) when it became available. The old by-pass system was changed to a BF-90 when it became available. Throughout its lifetime, the car had approximately 20 oil changes.
