Source note on shared footage
We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
Learn how to change the oil and oil filter in your 1990 GMC G2500 with this free video. What type of oil is required in a G2500? 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 G2500. The owners manual will indicate if your 1990 G2500 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 G2500. For most GMCs, 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 GMC G2500 oil filter wrench. If your G2500 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 G2500.
We recommend wearing safety glasses whenever you are working under your G2500. 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 1990 GMC G2500 更换机油和机油滤清器，观看本免费视频。 在 G2500 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 G2500 的驾驶员。 车主手册会说明您的 1990 G2500 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 G2500 机油和滤清器所需的步骤。 对于大多数 GMC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 GMC G2500 的机油滤清器扳手。 如果 G2500 离地过低，无法接近放油螺塞和机油滤清器，请在钻入 G2500 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 G2500 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。
