Does the Mondeo Burn Engine Oil?
2 Answers
Improper use of the Ford Mondeo can lead to engine oil burning. Engine oil naturally has a certain level of consumption, which is normal. However, excessive consumption indicates an oil-burning issue. Below is relevant information about engine oil burning: 1. Symptoms of engine oil burning: Blue smoke from the exhaust pipe during startup or during normal engine operation, while no pulsing blue smoke is observed at the oil filler port, or blue smoke from the exhaust pipe along with pulsing blue smoke at the oil filler port. 2. Solutions for engine oil burning: Cold engine oil burning: When the car's temperature hasn't fully warmed up, the engine exhaust emits significant blue smoke, but returns to normal once the engine is warm. This is caused by aging valve stem seals. Replacing the valve stem seals can resolve this. For warm engine oil burning that isn't severe (for safety, a cylinder compression test can be performed first), you can directly remove the oil pan, take out the pistons, and replace the piston rings.
Whether the Mondeo burns engine oil depends on the specific situation. New cars generally don't have this issue, but older Mondeo models, especially those with over 100,000 kilometers, occasionally experience oil burning. The most obvious symptoms are blue smoke from the exhaust pipe or a rapid drop in oil level between maintenance intervals. I've seen several cases caused by degraded piston ring seals, which are more likely to occur when driving aggressively at high speeds. Remember to use full synthetic oil and check the dipstick every 5,000 kilometers. If oil consumption exceeds 0.5 liters per 1,000 kilometers, it's time for immediate inspection and repair.
