Changing the oil in your Yamaha Golf Cart is easier said than done. Each golf cart has its oil specs and steps to be followed.
The 10-minute task of changing the oil in a Yamaha Golf Cart takes several minutes to an hour for a newbie to understand. Every step needs to be paid attention to and a wrong step can reduce the life of golf cart significantly.
This article tries to cover all those minute details and serves as a one-stop guide for anyone planning to change the oil on their own, in a Yamaha Golf Cart. I have tried to answer the basic questions first followed by a detailed step-wise explanation of the topics.
What Kind of Oil Does a Yamaha Golf Cart Use?
Yamaha recommends using the YamaLube non-synthetic 10W-30 oil for its golf carts.
Any oil with a viscosity range of 10W-30 is suitable for any Yamaha Golf Cart though. Citing the splash systems used in these golf carts, Yamaha recommends using only non-synthetic oils.
The specifications mentioned in a Yamaha golf cart’s user manual include a 10W-30 viscosity range along with API service SE, SF and SG.
Synthetic oils don’t make much of a difference though as they are good enough to hold their viscosity over a similar time as the non-synthetic ones.
Any suitable oil with a viscosity range of 10W-30 will work fine in a Yamaha golf cart.
How Often Should You Change the Oil in a Yamaha Golf Cart?
You should change the oil on a Yamaha golf cart every 150-250 hours of use.
If you are a regular cart user, 150-250 hours of operation should take around 6 months. The timeframe for changing the oil in any golf cart depends on the time for which the cart is operated.
If you can’t keep a track of your cart’s running hours, you can always turn to the dipstick oil level indicator. With the cart on a level surface and engine a little warm, take the dipstick out. Clean it with a dry piece of cloth and dip it in to check the oil level.
If the oil level is below the safe range, operating the cart without an oil change can leave the engine damaged. In case you’ve not operated your cart over the winter, it is advised to change the oil in spring. This is to remove any moisture that could’ve seeped in during the winter.
How Much Oil Does a Yamaha Golf Cart Take?
The engine oil capacity in Yamaha golf carts is usually greater than 1.0 L or 1 US qt. When the engine oil is completely drained out, a Yamaha golf cart can take in around 0.9 L or 1 US qt.
It is important to ensure that the engine oil is not overfilled. Overfilled engine oil can disrupt the flow of oil causing severe damage to the engine. It is as harmful as an engine running without engine oil. Often the crankshaft comes in contact with the oil adding air in the oil flow system.
Refer to the user manual to know the oil capacity of your golf cart. Once assessed, ensure you’re filling not more than 90% of the engine’s total capacity. The dipstick can be used to check the oil level after refilling. Remove the excess engine oil using the drain cap at the bottom.
Can you use Synthetic Oil in a Yamaha Golf Cart?
Yamaha does not advise the use of synthetic oil in its golf carts.
This is because the engine involves a splash system. The synthetic oil can prove to be too thin for Yamaha’s splash system mechanism.
There are several synthetic oil options available in the market with the YamaLube being the most popular for Yamaha golf carts. Mobil 1 non-synthetic oils can also be used and are quite good with golf cart engines.
The choice of synthetic and non-synthetic oil also depends on the temperature and work-load on the cart. One reason why non-synthetic engine oil is preferred over synthetic oil is that it holds its viscosity for a little longer. Though the difference is minimal, it is an important reason why synthetic oil is not advised by Yamaha for its golf carts.
How to Change Oil in Yamaha G2 Golf Cart
Changing the oil in a Yamaha G2 golf cart is easy and can be done without much fuss. All you’ll need is the right volume of oil and a clean dry cloth. Before beginning with the oil change, you should know how much oil is to be filled.
To know your golf cart’s engine’s capacity, refer to the user manual. Make sure you are using the right type of oil, which is usually 10W-30 non-synthetic oil for the Yamaha G2.
Follow these steps to change the oil in a Yamaha G2 golf cart.
- Drain the oil remaining in the engine by opening the drain plug at the bottom of the engine.
- Open the oil filler cap on top of the engine and using a filler, fill about 1.3 US qt of 10W-30 non-synthetic oil. Make sure you are filling oil only through the oil filler cap on top.
- Clean the dipstick with a clean piece of lint-free cloth and check the oil level with it.
- Ensure that the oil level has not exceeded more than an inch of the safety level marked on the dipstick.
Other Points to Remember:
- Make sure that the cart is at an even level while you’re checking the oil level.
- Do not mix two different oils. Whatever oil you choose, make sure you’re using just one type of oil. Do not mix two oils even if they are of the same viscosity range.
How to Change Oil in a Yamaha G16 Golf Cart
The procedure for changing the oil in a golf cart remains pretty much the same for most golf carts. The oil capacity of Yamaha G16 is lower than the Yamaha G2 and it can hold only around 1.16 US qt. The type of oil to be used remains the same; 10W-30 non-synthetic.
The position of the drain plug and oil filler cap is slightly different on the Yamaha G16. The following steps explain the complete procedure.
- The drain plug is right under the driver seat in the Yamaha G16 cart. You can un-screw that using a 17mm drain bolt.
- Once the engine oil is completely drained out, screw the drain plug back in its position.
- Open the oil filler cap on the top side of the engine.
- Using a filler, fill around 0.9 L of engine oil, preferably the YamaLube 4-stroke engine oil.
- Check the level with a dipstick and drain or add oil as required to match the safety level.
Things to Keep in Mind:
- The engine should be warm before starting with the oil change procedure.
- The cart should be parked on an even surface when the oil level is checked.
- Clean the dipstick with a dry and clean piece of cloth before dipping it in oil.
How to Change Oil in a Yamaha G29 Golf Cart
The Yamaha G29 has a different axle positioning which changes the position of the drain plug and oil filler cap. The volume of oil to be used is 1 US qt. You can follow the below steps to get the oil changed in your Yamaha G29 golf cart.
- The drain plug beneath the driver’s seat should be un-screwed with a bucket below the engine to drain out the oil in it.
- Remove the plastic Fill Bagto open the oil filler cap below it.
- To ensure no oil is spilled on or around the engine, use a filler. Fill 1 US qt of engine oil.
- Check with a dipstick to ensure that the oil level follows the safety level.
Things to Keep in Mind:
- Make sure the oil is not spilled on or around the engine as that could lead to a burning smell coming out of the engine.
- The oil level is to be checked only after ensuring that the cart is parked at an even level

Instructions for golf cart rear end oil change are usually provided by Yamaha in the respective service manuals. Following is a simplified step-wise guide to help you get it done.
- After ensuring the cart is parked at an even level, un-screw the oil servicing plug to drain out oil completely.
- After draining out the oil completely, screw back the oil servicing plug keeping a torque of 16.3 Nm.
- Open the transmission case by removing the bag tray rivets and bolts.
- Remove oil servicing plug now and fill it with the oil you prefer until oil starts oozing out of the oil servicing hole.
