If this mileage isn&rsquo;t achieved, the engine oil and the oil filter should still be changed at least once a year.<\/p>\n\n\n\n<p>The Sierra 3.0 Diesel is also equipped with an engine oil life system that calculates engine oil life based on vehicle use. It should display a warning when it&rsquo;s time to <a href=\"https:\/\/www.carparts.com\/blog\/how-to-change-your-oil\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"change the engine oil\">change the engine oil<\/a> and filter. If your truck is driven under the best conditions, the engine oil life system might not indicate a warning for up to a year. When this warning illuminates, the <a href=\"https:\/\/www.carparts.com\/blog\/why-you-should-always-consult-a-repair-manual\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"owner&rsquo;s manual\">owner&rsquo;s manual<\/a> says that you should replace your truck&rsquo;s oil within the next 600 miles or 1000 km. After an oil change, the oil life system should also be reset to 100%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2021 GMC Sierra 3.0 Diesel Oil Capacity and Type<\/h2>\n\n\n\n<p>The 2021 GMC Sierra 3.0 Diesel has an engine oil capacity of<strong> 6.6 liters or 7.0 quarts<\/strong>. GMC also recommends using engine oils that meet <strong>dexosD<\/strong> specifications, which are marked with the dexosD-approved logo.<\/p>\n\n\n\n<p>According to GMC, you should use engine oils that have a <strong>0W-20 viscosity grade<\/strong>. You also shouldn&rsquo;t use supplemental engine oil additives in your truck&rsquo;s engine because the oil alone is sufficient for good engine performance and lubrication.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other Notes About Changing Oil<\/h2>\n\n\n\n<p>Your truck&rsquo;s engine needs the right engine oil to keep its parts properly lubricated. If you fail to change your truck&rsquo;s oil on a regular basis, debris and other pollutants can accumulate in the oil, at which point it will become unable to adequately protect your engine from metal-to-metal contact between the parts. Excessive friction between engine components can hurt your truck&rsquo;s reliability and decrease its performance, and might result in costly engine damage.<\/p>\n\n\n\n<p>To get the best out of your pickup, make sure to change its oil and perform other maintenance tasks at the recommended intervals. You can change the oil yourself to save on costs if you have enough DIY automotive knowledge and experience or have it done at the dealership or at a reputable <a href=\"https:\/\/www.carparts.com\/installed\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"auto repair shop near you\">auto repair shop near you<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Get a Replacement Oil Filter that Fits Your Vehicle<\/h2>\n\n\n\n<p>It&rsquo;s best to replace the oil filter while changing the engine oil, especially if the part is old or worn out. Ignoring it can create engine problems, which might cost several times the price of a new filter. Thankfully, you can get a compatible replacement oil filter that fits your budget and vehicle at CarParts.com.<\/p>\n\n\n\n<p>Look no further than <a href=\"http:\/\/carparts.com\" target=\"_blank\" rel=\"noreferrer noopener nofollow\" aria-label=\"CarParts.com\">CarParts.com<\/a> when you need a high-quality oil filter delivered to your home in only a few business days.
