Passing a driving test has become a rite of passage for young adults, who often see only the excitement, independence and increased peer status of having personal transportation. At that point in life the boring, mundane details of vehicle maintenance may seem unimportant, until neglect results in expensive and time-consuming repairs. Engine sludge symptoms are a warning sign that trouble may be brewing.
Admonishing new drivers to change the oil every three thousand miles has become standard practice, even though it is not really necessary. The chemistry of oil as well as engines themselves have changed radically since the era when that advice actually mattered. Many newer vehicles can easily travel ten thousand miles before the lubricant becomes sub-par, but that particular number should never be taken literally.
The life-expectancy of an oil change depends on physical location, road conditions and driving habits. These can include many short trips of less than one mile, predominantly cold-weather operations, sharp stops and starts, and long idles. All these factors can contribute to degradation, requiring shorter intervals between changes. Longer periods allow the oil to become increasingly contaminated, encouraging sludge buildup.
Oil begins to break down immediately after being installed. Synthetic varieties combat this process most effectively, but even the longest-lasting must undergo periodic filtration. The main culprit is a process called oxidation, which speeds up during difficult driving conditions or high heat. The result is a gelatinous goo that contains solids, liquids, and gases, as well as burnt carbon residuals and metal particulates.
When this continues over extended periods due to neglect or environmental stresses, the gooey, gel-like substance can spread. Much like human arteries that become blocked with cholesterol, mechanical parts no longer operate efficiently. Baked on deposits eventually begin to strangle narrow passageways, and performance begins to suffer noticeably. Instead of lubricating, the oil causes overheating, and eventual damage.
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.
