What You'll Learn

The manual recommends 4 quarts
It is important to note that when changing the oil, it is recommended to put in only 3.5 quarts of oil, start the motor, and then check the oil level. This is because some oil will remain in the engine even after a complete drain. Running the motor will distribute the oil throughout the engine, and checking the oil level after it has been running will give an accurate reading.
After running the motor for a bit, shut it off and let it sit for about 10 minutes. Check the oil level using the "cold" check procedure. Then, start the motor again and let it warm up for about 40 miles. Check the oil level again using the "hot" check procedure. The oil level should be at the full mark on the dipstick when the engine is hot.
It is important to not overfill the oil, as this can lead to oil puking out of the air filter and blowing out of the filler neck. Always refer to the owner's manual for the specific recommendations for your vehicle.

3.5 quarts is enough
When it comes to the 2008 Harley-Davidson Electra Glide, the general consensus is that 3.5 quarts of oil is sufficient for an oil change. This is based on the recommendations and experiences shared by owners and enthusiasts of the bike. While the manual and some sources suggest using four quarts, several individuals have found that 3.5 quarts is adequate, and topping it up after a "hot" check procedure brings it to the appropriate level.
It is important to note that the oil capacity for the Electra Glide may vary slightly depending on the specific model year and type. For instance, some owners of the 2002 Electra Glide Standard have reported using 3.5 quarts, while others have mentioned being able to add four quarts. Similarly, for the 2012 FLHTK model, the manual recommends starting with three quarts and then adding more as needed, with 3.5 quarts being the maximum typically required.
When performing an oil change, it is crucial to follow the proper procedures and checks. One recommended approach is to put in 3.5 quarts of oil, start the motor, and then check the oil level after it has been running for a while. This process ensures that the oil has had a chance to warm up and circulate throughout the engine. It is also important to consider the type of oil being used, as synthetic oils may have different expansion properties compared to conventional oils.
Additionally, it is worth noting that overfilling the oil can lead to issues such as oil leaking out of the air filter or filler neck. Therefore, it is generally recommended to aim for a level that is slightly below the "full" mark on the dipstick. This allows for some expansion of the oil as it warms up and ensures that there is sufficient space for the oil to move within the engine.
In summary, based on the experiences of Electra Glide owners and enthusiasts, 3.5 quarts of oil is generally sufficient for an oil change. It is important to follow the recommended procedures and checks to ensure the correct oil level and avoid overfilling, which can cause problems. By taking a careful and measured approach, you can help ensure the optimal performance and maintenance of your 2008 Electra Glide.

Overfilling can cause oil to blow out
The 2008 Harley-Davidson FLHTCU Ultra Classic Electra Glide (1584) takes four quarts of oil. However, some users have reported that their manual states that only 3.5 quarts are needed. This is because some oil remains in the crankcase and in the engine.
Overfilling the crankcase with oil can cause excessive blow-by, where oil is puked out of the air filter and blown out of the filler neck. This is due to the crank hitting the oil and causing it to froth, which the oil pump cannot pick up, resulting in oil not reaching vital engine components. This can cause the engine to conk out.
To avoid overfilling, it is recommended to check the oil level with both the "cold" and "hot" check procedures. The "cold" check procedure is done after the engine has been off for some time, while the "hot" check procedure is done after the engine has been running for a while. It is important to note that the hot" check procedure is the one to "go by".
When performing an oil change, it is also important to ensure a complete drain of the old oil to avoid overfilling. Additionally, it is recommended to run slightly low on oil rather than risk overfilling, as this can cause oil to blow out.

It is important to use the correct type of oil for your motorcycle, as well as to check the oil levels after filling to ensure that the bike is not overfilled. Overfilling the oil tank can lead to oil leaks and damage to the engine. It is also important to change the oil regularly and to use the correct oil filter to maintain the health of the engine.
When changing the oil, it is recommended to start by draining the old oil from the engine, transmission, and primary chain case. Then, new oil can be added to each component, ensuring that the bike is level to get an accurate reading of the oil level. Finally, the oil levels should be checked with the bike running and the oil warmed up to get an accurate reading of the oil level.
By following these steps and using the correct amount and type of oil, you can help ensure that your 2012 Harley-Davidson FLHTK Electra Glide Ultra Limited runs smoothly and maintains optimal performance.

Primary takes 1 quart
The primary oil capacity of a motorcycle varies depending on the model and year. For a 2008 Electra Glide, the primary oil capacity is one quart or 32 ounces. This is based on the assumption that the transmission takes 1 quart of oil and the engine takes approximately 3.5 quarts of oil.
It is important to note that the oil capacity of a motorcycle can vary depending on the type of oil used and the specific model. Always refer to the owner's manual or a certified mechanic for the most accurate information regarding your motorcycle's oil capacity. Additionally, it is recommended to change the oil in a motorcycle at least once a year or every 5,000 miles, whichever comes first.
When performing an oil change, it is crucial to use the correct type of oil for your motorcycle. For the primary case of a 2008 Electra Glide, it is recommended to use shell rotella t 15-40 oil. However, it is always best to consult your motorcycle's owner's manual or a certified mechanic to ensure you are using the appropriate type of oil for your specific vehicle.
Overfilling the oil can lead to several issues, including oil leakage and increased crankcase pressure. Therefore, it is essential to follow the recommended oil levels and properly maintain your motorcycle to ensure optimal performance and avoid any potential damage caused by overfilling.
To check the oil level, it is recommended to use the "hot check" procedure. This involves starting the motor and letting it run for a while before shutting it off and allowing the oil to settle. Then, use the dipstick to check the oil level and ensure it is within the recommended range. By following these proper oil maintenance procedures, you can help ensure the longevity and smooth performance of your 2008 Electra Glide.
