Does skipping an oil filter change once in a while affect the car?
2 Answers
Skipping an oil filter change once in a while has no impact, but prolonged neglect can lead to excessive impurities on the filter paper, clogging its pores and reducing oil flow rate, which affects engine lubrication and normal vehicle operation. The oil filter removes impurities such as dust, metal particles, carbon deposits, and soot from the oil, supplying clean oil to components like the crankshaft, connecting rods, camshaft, turbocharger, and piston rings. This ensures lubrication, cooling, and cleaning, reducing engine wear, optimizing performance, and extending the lifespan of these parts. Maintenance tips: Replace the oil filter every 5,000–10,000 km; check the oil dipstick (oil level) weekly, monitoring oil color and viscosity changes. While the engine is running, regularly monitor oil pressure—if it's too low, replace the oil filter and restart to check. If pressure remains low, inspect the engine and the oil filter's filtration efficiency, ensuring it meets at least 70%.
From a technical perspective, skipping an oil filter change once might not seem like a big deal, but don't take it lightly. The oil filter's job is to remove impurities from the oil, such as dust and metal particles, protecting the engine's internal components from wear. If you skip a change, the filter may already be too dirty to filter efficiently, allowing some contaminants to enter the system, increasing friction and the risk of oil thickening. While you might not notice immediate problems in the short term, doing this frequently can shorten the engine's lifespan or lead to overheating issues. It's recommended to replace the filter with every oil change—after all, it's a small cost compared to the long-term performance benefits. Also, checking the oil's color can help detect abnormalities; if it turns dark or has particles, address it promptly. Regular maintenance is key to avoiding major repairs. Taking care of your car starts with small steps to ensure it remains safe and reliable.
