Engine Oil Capacity

Post by lear45jim »



Hello everyone. I've had my 1975 GL1000 a couple of years and ride less than 1000 miles per year. I change the oil and filter annually and both times I have noticed that filling with the 3.5 liters as is recommended in the owners manual results in an over fill. It appears to be closer to 3 liters, or maybe 2.75. Draining out the excess is a messy job but I know the importance of not operating an engine overfilled with oil.

Has anyone else encountered this or am I not getting a complete draining? My method for draining is to put the bike on a motorcycle jack which places it nice and level. Then I remove the filler cap, the drain plug and the filter/filter housing. Seems straight forward. Am I missing something?

If I get responses stating they too are only needing around 3 liters I will feel I am doing it right. However, if I get responses that 3.5 liters is right, I will know I am needing to change the way I drain the engine.

Thanks everyone for taking the time to help. This forum is awesome...what did we do before the internet?

3.5 liters (3.7 US qt) is correct, assuming the filter is changed, and all oil has drained out.

I will always make sure my bike is warm (engine hot, then let it cool slightly to prevent burns) before changing the oil. This thins the oil and makes sure it all drains out. Changing oil on a cold engine will not only take a long time, you won't get all the old oil out, as a thick layer will adhere to the insides.

Don't overfill your crankcase - if you are changing your oil and it takes 3.25 liters to get it to the full line on the window, then don't put more in just because the book says to.

You will be better served if you put the bike on the center stand. This will tilt the bike slightly to the front allowing all the oil to drain out.

Wow, I totally missed his statement that the bike was on a jack - you're 100% right. The fact that the bike is on a motorcycle jack instead of the center stand, will cause the crankcase to not fully drain. This is no doubt the reason it is not taking enough oil.

When on the center stand, the engine block is tipped slightly forward, to allow the oil to drain completely.

Thanks for your help. The problem was the bike being on the jack stand. Tilting forward made the difference. Now able to service with 3.5 liters of oil.
