The Ultimate Guide to Car Oil Filters Your car’s internal combustion engine is a complicated series of parts, fluids, and pressure systems—and for it to run right, everything has to work perfectly. Even the smallest hiccup can cause a cascade of ill effects down the road.Get more news about hyundai filter,you can vist our website! Now, most drivers are at least vaguely aware that they need to get their oil changed every so often. Yet, more folks don’t realize that there are other essential parts of their oil system that need to be swapped out at regular intervals as part of routine car care. That last point about the particle collection is the reason why fresh oil is a see-through, light golden color, whereas used oil is opaque, brown, and sludgy. That dark, sludgy oil needs to be changed after a while because it’s no longer greasing the engine properly. Left alone for long enough, this can cause catastrophic damage to the inside of the motor, or even cause the motor to lock up entirely—and this brings us to the role of the filter. The main purpose of an oil filter is pretty self-explanatory: it helps to filter those harmful particles out of the oil as it circulates through the engine. Think of it as a big loop through the entire system, with the filter being the finish line that catches all the crud the oil picked up as it went through. The oil in your car will flow through this process thousands of times before it needs replacing, but without a properly working filter, the oil accumulates debris at a much faster rate. Regardless of how good your filter is, it can’t prevent all particles from accumulating in the oil, which is why regular oil changes are necessary. Whenever an oil change is performed, it’s imperative to check the state of the filter as well. How Often Should I Change My Oil Filter? This question is always the subject of debate, but the general consensus is that it ought to be swapped out as part of every oil change. This, of course, depends on the car you’re driving, the conditions you’re driving it in, and the type of oil you use. If you’re driving, say, a brand new Elantra with full-synthetic oil and a good oil filter, you might be able to make it 10,000 miles without a visit to the shop. If you’re driving an older model with conventional oil and the worst oil filter, or you frequently drive in rough conditions, your oil and filter may only last up to 4,000 miles.
