GM Oil Life Monitor System
Frequently Asked Questions
How does the system work?
The GM Oil Life Monitor System is not a mileage counter. It is actually a computer
based software algorithm that determines when to change oil based on engine operating
conditions. There is no actual oil condition sensor. Rather, the computer continuously
monitors engine-operating conditions to determine when to change oil. Over the years,
millions of test miles have been accumulated to calibrate the system for a variety of
vehicles. The system was first introduced in 1988 and is now on more than 10 million
GM vehicles.
非单纯计算里程，也没有机油检测传感器，而是基于发动机工作条件的检测而计算出来的。（从别的资料来看，可能是根据发动机总转数、机油温度、气候条件等计算的).
How do I operate the system?
The GM Oil Life Monitor System is very easy to use. First, refer to the vehicle owner’s
manual for a description of the specific ‘change oil’ message and the instructions for
resetting the system. When the vehicle has been driven the appropriate miles, the ‘change
oil’ message will be illuminated on the instrument panel or driver information center
when the vehicle is first started. An oil change should be done within two fuel tank fillups from when the message was first displayed. Immediately after the oil has been
changed, the system must be reset. After resetting, the ‘change oil’ display will no longer
be displayed after engine start up.
机油灯亮起以后2箱油以内需更换。同时必须复位机油寿命。
How many miles can I expect to go between oil changes when using this system?
The beauty of the GM Oil Life Monitor System is that it will automatically adjust the oil
change interval based engine characteristics, driving habits and the climate in which the
vehicle is operated. For instance, mild highway driving in a warm climate will maximize
the interval between oil changes. Depending on the vehicle, this could be in excess of
7000 miles and as high as 12,000 miles. On the other hand, short trip driving in cold a
climate may limit the oil change to 3000 miles or less. In general, most people that drive
a combination of city and highway schedules find that the GM Oil Life Monitor System
will indicate an oil change every 7500 to 8500 miles.
根据发动机特性，驾驶习惯，气候条件自动调整换油间隔。温和高速驾驶可以使机油寿命最大化。短途冷天驾驶，机油寿命明显缩短。
Do I have to check my oil level now that my vehicle is equipped with the GM Oil
Life Monitor System?
Yes, the system does not sense oil level. As stated in the owner"s manual, it is
recommended that you check your oil every time you stop for gasoline.
该系统不检测机油液位。
I use synthetic oil, should I expect to get more miles before the trigger point with
GMOLS?
The GM Oil Life System is calculated based on the factory fill requirement. While some
benefits may exist, the oil drain interval is not extended due to the use of synthetic oil.
全合成机油并不会延长机油换油间隔，虽然可能有一些好处。
I drive my vehicle in a very hot climate, do I need to change oil
more often?
The beauty of the GM Oil Life System is that it calculates for severe climate use and
determines the oil change interval just as it does for trailer towing as well as stop and go
operation. There is no need to adjust the oil change based on climate, as well as vehicle
use.
不需要特别考虑极端气候条件和驾驶习惯(意思是系统自动调整)。

另:
发动机在80-140度有利于延长机油寿命。

通过机油油液分析(实线)和GM机油系统(虚线)分别决定换油间隔的公里数对比(对于不同驾驶情况的车辆)，还是比较接近的。
