Car ownership is a world filled by myths, where some myths transcend from one generation of car owners to the next. We cannot find out exactly when rumors about GMC trucks that have started thicker steel than Chevys, and one of the stupidest autemyths we have heard is that reversing a car when the engine is cold, causes permanent and irreversible engine damage. Moreover, the worst autofyths that get stuck are the idea that lifelong liquids never need replacement.
Speaking of liquids, engine oil have a good part of the myths that refuse to fade. One of them is that thicker oil, or one that has a higher viscosity classification, offers better protection than thinner, low viscosity oil. The truth is that choosing the right oil based on the expected ambient temperature is much more effective than debating whether thinner or thicker oil is better.
If the owner’s manual recommends 5W-30 Synthetic oil in the summer and 0W-40 in the winter, then keep up and it will be fine. Unfortunately, more Oliemythen has to disprove, and we have identified four that persist despite the wealth of reliable information online.
Dark oil means dirty oil and has to drain as quickly as possible
Modern synthetic oils contain additives, detergents and friction modificators who start working immediately after starting the engine. Fresh oil has a usually dark golden hue, but it is relatively normal that it gets darker or becomes black while cycling over your motorcycle. To begin with, heat the engine from cold to hot to cold to cold, will make the color of the oil of your motor darker in a natural way. In addition, additives in modern synthetic oils tend to become darker or to undergo a color change when repeatedly exposed to heat, pressure and oxidation.
In addition, motor deposits and sludge have a dark brown or black color, and fresh oil naturally becomes darker when it breaks down and absorbs dirt and contaminants. The same applies to diesel engines that produce more soot than a similar petrol car, and that is why diesel oil tends to turn black faster after an oil change. In short, oil that changes color means that the liquid does its best to clean and spread the engine, and the color of the oil has no influence on when it is time to replace it. A safer gamble is to consult the owner’s manual to find out more about the recommended intervals for oil change for your car.
Switching from conventional to synthetic oil will cause leaks
Contrary to what others could say, it is relatively safe to switch from conventional oil to full-synthetic melanges for older engines. The myth over synthetic oils that cause oil leaks dates from the early 1970s, when early formulations contain synthetic oils ester, a chemical connection with advanced detergents to prevent sludge and lubricants to maintain the integrity of rubber seals.
On the other hand, scientists and researchers discovered that repeated and long -term exposure to Esters ensures that the seals swell and break down, leading to unexpected oil leaks. Fortunately, oil manufacturers have avoided Esters in their synthetic oil products, and even Porsche recommends synthetic oil for vintage classics, such as air -cooled 911S and the iconic Porsche 356.
Moreover, your engine probably needs new oil ring when leaks are present and it has nothing to do with switching from conventional to synthetic oil. Perhaps the only disadvantage of choosing fully synthetic oil is the costs, because you spend more on any oil change. However, the extra money is worth it, because synthetic oils can last up to 8,000 or 10,000 miles between oil changes.
It’s okay to skip oil changes after the engine is insured with oil
Not all engines are the same because some have a tendency to consume more oil than most. In some brands and models, their engines can burn enough oil to draw the oil pan considerably enough to illuminate the low oil lamp, even before the interval with oil change recommended by the factory. We are talking about some Subaru Forester models, GMC SUVs and high-quality BMWs with 4.4-liter V8 engines, according to Consumer reports.
On the other hand, some cars such as the legendary Honda S2000 can burn a liter of oil when stretching its high-rise VTEC engine to the limit, and it is typical for S2000 owners to have a liter or two fresh oil in the trunk for immediate addition. You are a good driver if you periodically inspect the oil level and add oil when needed. However, you earn a beating if you think it is good to skip an oil change after topping the engine.
Adding fresh oil to maintain a fixed level differs from compliance with regular oil changes. The oil often changes and insist on the use of oil with the correct viscosity is one of the accurate ways to extend the lifespan of the engine of your car.
You do not have to replace the oil filter with every oil change
Skimpen on oil changes will inevitably change old, dirty oil in sludge. However, skipping oil changes and not replacing the oil filter is a double Whammy, but not in a good way. Dirty or stuffy oil filters can reduce oil pressure and impede the oil flow to critical engine parts, leading to premature wear, increased motor heat and reduced fuel consumption. The worst-case scenario is an overheating engine and thousands of dollars in damage and labor, all because of an oil filter that costs less than $ 10 to about $ 100 everywhere.
Make it a habit to replace the oil filter when the oil is changed. Do not forget to spread the new oil filter wrapping with fresh oil before fixing it to the block again. And while you are working on it, you are resisting the urge to tighten the oil filter with the help of an oil filter key, because it is sufficiently faded to form a leak -free seal.
