* Diesel engines are built for longevity: Diesel engines are known for their durability and can often last much longer than gasoline engines.
* Mileage is relative: 120,000 miles is a significant amount of driving, but it's not extreme for a diesel engine. Some diesel engines can easily go 200,000 miles or more with proper maintenance.
* Driving conditions matter: How the engine was driven is important. If the majority of the driving was highway miles at steady speeds, the engine is likely in better shape than if it was driven frequently in stop-and-go traffic or under heavy loads.
* Maintenance is crucial: Regular oil changes, filter replacements, and other routine maintenance are essential for extending the life of any engine, diesel or gasoline.
To determine if 120,000 miles is bad for a specific diesel engine, consider these factors:
* Engine model: Different diesel engines have different expected lifespans.
* Maintenance history: Has the engine received proper and regular maintenance?
* Driving conditions: Was the engine driven primarily on highways, in city traffic, or under heavy loads?
* Any existing issues: Are there any known issues with the engine, such as leaks or performance problems?
If you're considering buying a diesel vehicle with 120,000 miles on it, it's wise to have it inspected by a qualified mechanic to assess its condition and determine its potential lifespan.
