Oldsmobile Ninety-Eight (1970)

COMMON FAULTS
Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

The 1970 Oldsmobile Ninety-Eight, like many classic cars, had its share of common faults. Here are some of the issues that owners have reported:

1. **Electrical Problems**: Issues with the electrical system, including faulty wiring and malfunctioning switches, were common.
2. **Engine Troubles**: Problems such as overheating, oil leaks, and carburetor issues were frequently reported.
3. **Transmission Issues**: The automatic transmission could sometimes be problematic, with reports of slipping and difficulty shifting.
4. **Suspension and Steering**: Wear and tear on suspension components and steering issues were common, leading to a less smooth ride.
5. **Rust and Corrosion**: Like many cars of its era, the Oldsmobile Ninety-Eight was prone to rust, especially in areas with harsh weather conditions.

These issues are typical for a car of this age and can often be addressed with proper maintenance and care.
