Procedure notes
See how to add oil to your 2003 GMC Envoy and where to add oil. This video shows the location of the oil filler cap and how to find the filler cap in a 2003 Envoy. Before adding oil to your Envoy, make sure that your engine was cold and that your car was parked on a level surface when you checked the oil level otherwise you won't be able to tell if your Envoy has a low oil level.
How much oil does my car take? For most GMCs, if your oil level is at the minimum mark on your dipstick, you should add about a quart of oil to get to a point where the car is safe to drive. If you drained all of the oil, check your owners manual for the 2003 GMC Envoy oil capacity.
Why is my car low on oil? Your car is leaking oil or your car is burning oil. Symptoms of an oil leak include oil leak coming from the Envoy’s oil drain plug, a leaky oil filter gasket, a leak at the rear main seal, a loose oil fill plug or any other location that causes oil to leak under the car. It is typically okay to drive a car with an oil leak as long as you add fluid regularly and do not let the fluid leak get too low. You can often fix an oil leak yourself for cheap by adding an oil leak stopper directly to the Envoy oil fill hole. Otherwise, you need to identify where the oil leak is coming from and fix that part.
If your 2003 GMC has a low oil light on, that means you have low oil pressure, which indicates a mechanical problem and you should not drive your car and turn your engine off.

查看如何为您的 2003 GMC Envoy 添加机油以及添加机油的位置。 本视频展示了 2003 Envoy 车型中机油加油口盖的位置以及如何找到加油口盖。 在给您的 Envoy 添加机油之前，请确保在检查机油液位时发动机是冷的，并且车辆停放在水平地面上，否则将无法判断您的 Envoy 是否机油液位过低。
我的车需要多少机油？ 对于大多数 GMC 车型，如果机油液位处于油尺的最低刻度线，应添加约一夸脱机油，使油位达到可以安全驾驶的水平。 如果你已经排空了所有的机油，请查阅2003 GMC Envoy车主手册中的机油容量说明。
我的车为什么机油不足？ 你的车在漏油或者在烧油。 机油泄漏的症状包括机油从Envoy的机油放油螺栓处渗出、机油滤清器垫圈漏油、后主密封处漏油、机油加注螺栓松动或任何导致机油在车底渗漏的其他位置。 原作者表示，在定期补充机油、避免机油液位过低的前提下，存在机油渗漏的车辆通常仍可行驶。 你通常可以自行低成本修复机油泄漏，方法是将油封堵器直接安装到Envoy的机油加注孔上。 否则，你需要确定机油泄漏的位置并修复该部分。
如果您的 2003 GMC 车辆出现机油压力低的警告灯，说明机油压力不足，这表明存在机械故障，您不应继续驾驶车辆，应立即关闭发动机。
