Hence, they strongly need constant oil changes for lubrication and reduced friction.&nbsp;<\/p>\n\n\n\n<p>Old oil sitting too long in the tank cannot give these components the necessary friction protection, which inevitably leads to severe damage and premature wear.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Blown Head Gaskets<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"479\" src=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Worn-Gasket.jpg\" alt=\"Blown Head Gaskets\" class=\"wp-image-2204\" srcset=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Worn-Gasket.jpg 800w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Worn-Gasket-300x180.jpg 300w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Worn-Gasket-768x460.jpg 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>Head gaskets are installed between the cylinder heads and engine blocks, a critical element in the internal combustion chamber. It seals the oil and coolant passages to ensure both systems operate effectively and independently.<\/p>\n\n\n\n<p>Needless to say, the severe lack of lubrication will stain the gasket with dirt and grim, eventually blowing it. Fixing these gaskets can be quite a financial pain.<\/p>\n\n\n\n<p>Once I noticed my old 2010 Ford Ranger always leaving a cloud of white smoke behind when I pressed the gas pedal. I thought it was because of the outdated exhaust pipe and dragged my feet on fixing it, but then, I ended up with a <strong>$4000<\/strong> engine swap since the bearing damage was already there. So do not follow in my footsteps.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Excessive Heat in The Engine<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Excessive-Heat-in-The-Engine.jpg\" alt=\"Excessive Heat in The Engine\" class=\"wp-image-2578\" style=\"width:586px;height:419px\" width=\"586\" height=\"419\" srcset=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Excessive-Heat-in-The-Engine.jpg 800w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Excessive-Heat-in-The-Engine-300x215.jpg 300w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Excessive-Heat-in-The-Engine-768x549.jpg 768w\" sizes=\"(max-width: 586px) 100vw, 586px\" \/><\/figure>\n\n\n\n<p>A common assumption is that just the coolant system is enough for engine cooling &#8211; but that cannot stray further from the truth. Oil also seizes a major role in such regard, as it can flow to places far from the coolant&#8217;s reach.<\/p>\n\n\n\n<p>When reaching old age, the oil grows thicker and gradually deteriorates due to high-temperature exposure. Due to this thermal breakdown, it can no longer absorb heat for the engine, which causes the latter to heat up beyond control, warp, and wear out.&nbsp;<\/p>\n\n\n\n<p>If there is no punctual fix for this issue, engine failure or shutdown will only be a matter of time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Dirt Buildup<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Dirt-Buildup-Engine.jpg\" alt=\"Dirt Buildup Engine\" class=\"wp-image-2577\" style=\"width:668px;height:376px\" width=\"668\" height=\"376\" srcset=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Dirt-Buildup-Engine.jpg 800w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Dirt-Buildup-Engine-300x169.jpg 300w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Dirt-Buildup-Engine-768x433.jpg 768w\" sizes=\"(max-width: 668px) 100vw, 668px\" \/><\/figure>\n\n\n\n<p>Aside from cooling and lubricating, the oil helps clean up your engine&#8217;s inside as well; it removes debris and small particles that may otherwise build up and lead to decreased engine life.<\/p>\n\n\n\n<p>And that is only the beginning of the nightmare: a dirted engine has to work twice as hard to propel the car&#8217;s operation, which leads to serious power loss.\u00a0<\/p>\n\n\n\n<p>Worse, the old oil becomes solidified and turns into sludge, meaning it can no longer flow to all engine components like it used to. The relief valve trains, camshafts, bearings, and crankshafts suffer from extreme oil starvation, which may cause total engine destruction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Worse Fuel Consumption<\/strong><\/h3>\n\n\n\n<p>As briefly mentioned above, the engine must work much harder than average due to the lack of friction and lubrication. It means your car will eat up much more fuel for one engine power unit, increasing the consumption rate by 1 to 2%.&nbsp;<\/p>\n\n\n\n<p>The number may seem trivial at first &#8211; but imagine the amount of wasted money if you let that issue extend for months or even an entire year.<\/p>\n\n\n\n<p>And do not let me start on the toxic smoke released into the air when the old oil burns, which worsens the car&#8217;s emissions.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Loud Noise<\/strong><\/h3>\n\n\n\n<p>After a while, your car will start making different noises than usual under excessive strain.&nbsp;<\/p>\n\n\n\n<p>Some may shrug at these noises and assume they will eventually go away; unfortunately, that scenario is very unlikely. Unless you go to a nearby station and change the oil immediately, these sounds will only worsen the longer you drive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Plenty of Oil Leaks<\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Oil-Spots-On-The-Ground.jpeg\" alt=\"Oil leakage from old car.\" class=\"wp-image-2203\" style=\"width:587px;height:392px\" width=\"587\" height=\"392\" srcset=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Oil-Spots-On-The-Ground.jpeg 800w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Oil-Spots-On-The-Ground-300x200.jpeg 300w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/Oil-Spots-On-The-Ground-768x513.jpeg 768w\" sizes=\"(max-width: 587px) 100vw, 587px\" \/><\/figure>\n\n\n\n<p>Under normal circumstances, high-quality engine oil forms solid layers on the inner walls of the engine to fill the gaps between the pistons and cylinder, preventing fuel leaks through those gaps. That partly explains why oil changes are so important.<\/p>\n\n\n\n<p>Old oil obviously does not have the same sealing power as new oil. The metals in the tank will expand, pushing the pistons over their boundaries and overwhelm the engine.&nbsp;<\/p>\n\n\n\n<p>The gaps within the tank grow larger, paving the way for fuel leaks and robbing your car of power. Do not be surprised if there is a noticeable quality decrease in your driving experience.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Voided Warranty<\/strong><\/h3>\n\n\n\n<p>Warranty policies only hold up when you abide closely by the manufacturer&#8217;s recommended maintenance &#8211; including oil service intervals. And that is to be expected: no brands are willing to fix your car for free when their defects are clearly your fault.<\/p>\n\n\n\n<p>In that case, the only choice left for you is to pay a higher price for the damage repairs &#8211; some of them can cost thousands of dollars and strike quite a blow on your total budget.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-often-should-you-change-your-oil-at-auto-shop\"><strong>How Often Should You Change Your Oil At Auto Shop?&nbsp;<\/strong><\/h2>\n\n\n\n<p>The recommended oil change schedules are <a href=\"https:\/\/www.corwheels.com\/how-often-should-you-change-your-oil\/\" data-type=\"URL\" data-id=\"https:\/\/www.corwheels.com\/how-often-should-you-change-your-oil\/\">every 3000 to 5000 miles<\/a>. Of course, several external factors also affect the recommended frequency, such as oil type, driving habits, and car age.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/labor-change-oil.jpeg\" alt=\"labor change oil\" class=\"wp-image-2566\" style=\"width:579px;height:384px\" width=\"579\" height=\"384\" srcset=\"https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/labor-change-oil.jpeg 800w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/labor-change-oil-300x199.jpeg 300w, https:\/\/www.corwheels.com\/wp-content\/uploads\/2023\/05\/labor-change-oil-768x510.jpeg 768w\" sizes=\"(max-width: 579px) 100vw, 579px\" \/><\/figure>\n\n\n\n<ul>\n<li><strong>The oil type.<\/strong> Synthetic oil (0W-20, for instance) lasts much longer than regular oil.
