For many young adults, getting a license to drive is more than a modern rite of passage. It means independence, freedom, and elevated status among friends. While that attitude is completely normal, most teenagers do not consider routine vehicle maintenance nearly as exciting. No matter how impressive a car may look from the outside, engine sludge symptoms can be an indication of future problems.
It has become standard procedure to admonish new drivers to change vehicle oil every three thousand miles, but that advice is no longer essential. Engines have evolved, and so have the lubricants that allow them to operate. The every-three-months oil change becomes unnecessary when new vehicles routinely operate for ten thousand miles before lubricants show signs of stress. That mileage number, however, is not a precise guide.
When normal vehicle operations include jackrabbit starts and stops, extended idle times, consistently poor road conditions, trips under one mile, and predominantly cold weather conditions, lubricants begin lose their consistency faster. This means that the frequency of oil changes should be based on personal driving habits and geographical location, not an arbitrary number. Longer intervals encourage sludge buildup.
Lubricants begin to break down as soon as they are installed. The addition of synthetics can delay that process significantly, but even they must be filtered periodically. Oxidation is the main culprit, and it increases along with operating temperature or difficult driving conditions. The chemical changes involved in oxidation create a thick goo made of liquids, gases and solids containing carbon residue and metal particles.
When oxidation continues due to environmental stress or simple neglect, this substance can end up coating most moving parts. Like human arteries blocked by atherosclerosis, they may still work, but not very well. Narrow machine tolerances or restricted passages become strangled, and overall performance becomes sub-par, with poor acceleration and gas mileage. Rather than providing lubrication, the oil becomes damaging.
No one wants to see warning lights on the dashboard. Regular oil changes and related routine maintenance may not always be convenient, but remain the best way to prevent trouble related to lubrication. The cost of replacing the engine is far higher, and is time-consuming as well. In some cases, however, cars develop internal sludge even when maintenance suggestions are followed precisely.
This perplexing problem has dogged several major auto-makers, and is not unique to a particular brand. Publicized legal actions unearthed no generalized issues within the industry, but rather revealed that some specific models and makes use more oil due to design quirks. While this issue is not on the same level of importance as recent widespread safety recalls, it can pose a significant problem for people buying used cars.
Before making a purchase, have the formerly owned car checked for signs of recent engine flushing, which may indicate a previous problem. Check the maintenance record, and never buy a car that an owner did not properly maintain. After making the purchase, using modern synthetic lubricants can prevent further problems, especially when urban driving predominates. The buildup of engine sludge is not inevitable, and can be prevented.
