If you’re exploring the possibility of buying a used car, one common issue to be aware of is the ‘oil burner’ problem. This term refers to vehicles that consume engine oil excessively, which can be a significant drawback depending on the model and condition of the vehicle. Here are some key points to consider if you find yourself in this situation:
Identifying Oil Burners
Check for Blue Smoke: One of the most telling signs is blue smoke from the exhaust, especially on startup or during acceleration.
Puddle of Oil: Look for oil spots where the car is parked. This could indicate a leak or excessive consumption.
Oil Level Drops: If the oil level drops quickly between oil changes, it could mean the engine is burning oil.
Common Causes
Worn Piston Rings: These can lead to oil leaking into the combustion chamber.
Valve Seal Issues: Worn valve seals can also allow oil to enter the combustion area.
Turbocharger Problems: If the vehicle has a turbo, issues here can lead to oil burning as well.
Repair Options
Piston Ring Replacement: This is a more extensive job and might not be worth it on older vehicles, so weigh the cost against the car’s value.
Adding Stop-Leak Products: Some products can temporarily help with minor leaks or burning but are generally short-term fixes.
Regular Maintenance: Keeping up with oil changes and monitoring oil level can help catch issues before they worsen.
Models Known for Oil Burning
Some particular models and brands have gained reputations for having oil burning issues, so do some research before committing to a purchase. Community knowledge is invaluable in identifying potential red flags.
