Engine sludge is old and congealed oil resulting from excessive contamination, heat and oil additive breakdown. Sludge typically forms over a long period of time and generally builds up when a vehicle owner skips oil changes or travels many miles past the recommended oil change interval.
If you are unsure how often to change the oil, make sure to contact us. We can advise you on the recommended oil change interval your vehicle should have. If you delay changing the oil, this can cause the issue. Over time, motor oil becomes contaminated with engine metals, acids and air humidity, eventually transforming into sludge. Waiting too long to change your oil will increase the likelihood of sludge infecting all the parts where it is contact with the oil.
Excessive heat from the engine causes the oil to breakdown resulting in sludge and engine deposits. The high temperatures also cause oil to thin out. This typically results in metal on metal grinding or wears in your engine. This problem typically can become even more severe if you tow heavy loads or if you leave your vehicle running idle for extended periods of time. A higher-grade oil will greatly benefit your vehicle in this situation. Repeated short distance driving means your oil may not have time to reach optimal operating temperatures. This enables water and combustion bi-products, such as smoke, to dilute oil, accelerating the breakdown of your oil and shortening the lifespan of your engine components.
Very hot or very cold temperatures will cause faster oil breakdown, requiring oil changes sooner. The oil gets thicker as the temperature drops. Oil is harder to pump during startup, potentially leading to accelerated engine wear and difficulty starting your vehicle. Remember, thinner oils are ideal during winter. The lower the grade, the thinner the oil, and the easier your vehicle will start during those deep freezes. By keeping up on regular oil changes, you can help prevent further damage to your vehicle. If you inspect the oil and notice dirt and debris, it is recommended to have it changed so fresh clean oil can run through your vehicle. When the oil is changed, the oil filter can also be checked. The filter helps to collect dirt and other contaminants that are in the oil.
