Is a Major Overhaul Necessary for a 10-Year-Old Car Burning Oil?

[Clay]

Whether a major overhaul is necessary for a 10-year-old car burning oil depends on the remaining value of the vehicle. The specific circumstances are as follows: Necessary: If it is still worthwhile, then opt for a major overhaul. Unnecessary: If the vehicle is already unusable and will soon be disposed of, then a major overhaul is not needed. Information about oil burning is as follows: Oil burning: Refers to engine oil entering the combustion chamber of the engine and participating in combustion along with the air-fuel mixture. Consequences: The phenomenon of 'oil burning' in a vehicle can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idle, lack of acceleration power, increased fuel consumption, and excessive exhaust emissions. In severe cases, insufficient engine lubrication can cause irreparable damage or even total engine failure, significantly increasing repair costs and potentially creating safety hazards.
