The answer depends on the motor oil that you use. While some may recommend having different intervals for all 3 components ( 3 holes – Engine, Primary, Transmission), we like to change the oil in all 3 every time we do a change, which is typically every 3000-4000 miles. Consult your owner’s manual for recommended numbers, but the fresher you keep the oil, the better the bike will run.
Make sure to check the oil gauge to make sure it is at the correct level. There are two general ways to check the oil in your Harley: by looking at the oil filter or by checking the dipstick.
To change the oil in your Harley, you can follow the schedule recommended in your owner’s manual. For example, you may change the oil in your motorcycle every 1000 miles or 5000 miles. The oil in the primary and transmission differs from the engine oil, so you need to consult the manual for your specific model. You can also keep the oil change schedule in your smartphone. When changing the oil in your Harley, make sure to check the dipstick for two marks. One mark will be the oil level, while the other mark will be the oil quantity.
When it comes to the interval, the most common recommendation is every 2,000 to 3000 miles. However, some riders do not exceed this amount in a year. Based on those experiences, the safest interval (maximum) is 5000 miles. Some bikers only reach that mileage in a couple of weeks. It’s not a big deal to change the oil, but it adds up to the running costs of your motorcycle. If you neglect to do this, you can end up spending a lot of money on repairs, so it’s important to get your oil changed at the right time.
