There are a few things to consider when choosing the right oil for your golf cart. The most important factor is the climate you live in. If you live in a hot climate, then you will want to use a lighter oil such as 5W 30. This will help keep your engine cool and prevent any damage that could occur from overheating. If you live in a cold climate, then you can use a heavier oil such as 10W 30. This will help keep your engine warm and prevent any damage that could occur from freezing.
Another factor to consider is the type of oil you want to use. Synthetic oils are typically more expensive, but they can last longer and protect your engine better. If you are on a budget, then you can use a conventional oil. Just be sure to change it more often to prevent any build-up from happening.
Overall, there is no wrong answer when it comes to choosing the right oil for your golf cart. Just be sure to consider the climate you live in and the type of oil you want to use.
