What are the effects of excessive engine oil?
2 Answers
Engine oil overfilling may cause: 1. Increased internal power loss due to component agitation during engine operation; 2. Excessive oil splashing onto cylinder walls, leading to oil burning and exhaust system malfunctions; 3. Elevated oil pressure resulting in poor component operation and reduced engine power output. Solutions for excessive engine oil include: 1. Warming up the engine or highway driving in cold conditions to reach optimal operating temperature, allowing evaporation of fuel/water contaminants; 2. Seeking professional diagnostic inspection to identify root causes.
I recently encountered the issue of engine oil dilution. The first time I noticed it was when checking the dipstick and found the oil level above the maximum mark, even though I had just done the maintenance. This situation is quite worrying - the engine feels sluggish when starting up, makes more noise, and fuel consumption has increased significantly. A friend told me this could be due to coolant leakage or unburned gasoline seeping in, which would reduce the oil's lubricating properties. I ended up going to the repair shop and spent nearly two thousand yuan cleaning the system and changing the oil. Now I've developed the habit of checking the oil level monthly to avoid greater losses. If you notice similar symptoms, don't delay - address it early to prevent breaking down on the road and wasting money. Remember, even new cars have had recall incidents where certain engine designs were inherently prone to problems.
