Procedure notes
Learn how to change the oil and oil filter in your 2021 Chevrolet Trailblazer with this free video. What type of oil is required in a Trailblazer? You can use synthetic oil in any modern vehicle. Many vehicles will require the use of 100% synthetic oil, others allow synthetic blend, which is a mix of synthetic and conventional oil, and conventional oil too. The synthetic oil vs conventional oil debate has many proponents on both sides. Synthetic oil will not break down over time and tends to have longer change intervals, so if you want to have more time between oil changes, then synthetic oil is a good choice. Conventional oil works well for drivers who change their oil regularly and if it is approved for your Trailblazer. The owners manual will indicate if your 2021 Trailblazer takes 0W-20, 0W-30, 5W-20, 5W-30 or 10W-30. This video shows the location of the oil drain plug, oil filter, oil fill cap and dipstick in addition to the steps needed to change the oil and filter in your Trailblazer. For most Chevrolets, you can wrap an old belt around the oil filter and unscrew it by hand. If you can't do this, see our parts page to find a Chevrolet Trailblazer oil filter wrench. If your Trailblazer is too low to the ground to access your drain plug and oil filter, be sure to use jack stands and safe jacking procedures before getting under your Trailblazer.
We recommend wearing safety glasses whenever you are working under your Trailblazer. You never know what could be dripping down from the engine, battery acid, engine coolant, brake fluid, etc. All of these fluids are harmful to your eyes and skin so it is important to protect yourself.

学习如何为您的 2021 雪佛兰 Trailblazer 更换机油和机油滤清器，观看本免费视频。 在 Trailblazer 中需要使用哪种机油？ 您可以在任何现代车型中使用合成机油。 许多车辆需要使用 100% 合成机油，其他车辆则允许使用合成混油，即合成油与常规机油的混合物，以及常规机油。 合成油与传统机油的争论双方都有支持者。 合成机油在使用过程中不会分解，且通常具有更长的更换周期，因此如果你希望在两次换油之间有更长的时间，那么合成机油是一个不错的选择。 常规机油适用于经常更换机油且该机油被批准用于您的 Trailblazer 的驾驶员。 车主手册会说明您的 2021 Trailblazer 需要使用 0W-20 0W-30 5W-20 5W-30 或 10W-30。本视频展示了机油放油螺栓、机油滤清器、机油加注盖和油尺的位置，以及更换 Trailblazer 机油和滤清器所需的步骤。 对于大多数 雪佛兰 车型，你可以将旧皮带绕在机油滤清器上，然后用手拧下滤清器。 如果你无法完成此操作，请查看我们的配件页面，找到适用于 雪佛兰 Trailblazer 的机油滤清器扳手。 如果 Trailblazer 离地过低，无法接近放油螺塞和机油滤清器，请在钻入 Trailblazer 车底之前，务必按安全举升步骤操作，并使用支车架支撑车辆。
在 Trailblazer 车底作业时，建议始终佩戴护目镜。 你永远不知道发动机上会滴落什么，比如电池酸液、发动机冷却液、制动液等。 所有这些液体对眼睛和皮肤都有害，因此保护自己非常重要。
