| + | ====== Should You Drain the Engine or Oil Tank? ====== | ||
| + | |||
| + | On a normal oil change, none of us can drain All the oil out. When we drain the oil, we are only draining the oil tank and not the engine. \\ | ||
| + | |||
| + | Do Not drain the oil until you've taken the bike on a 15-20 min ride. This will allow the oil to be scavenged by the pump to the oil tank. \\ | ||
| + | It'll also suspend debris in the oil instead of it laying on the bottom and not being drained. \\ | ||
| + | In gerotor oil pumps, the return side is much bigger than the feed side. \\ | ||
| + | So firing up the bike sends the oil accumulated in the sump back to the tank faster than more oil can accumulate in the engine. \\ | ||
| + | This fills the oil level back to where it should be. See also, [[techtalk:ref:oil01#overfilling_the_oil_tank|Overfilling the Oil Tank]] above. \\ | ||
| + | |||
| + | The drawing below shows the oil path for 1992-1997 Sportsters. All mini-sump engines are the same as far as oil scavenging goes. \\ | ||
| + | |||
| + | The yellow portion in the bottom represents oil in the sump waiting to be picked up by the oil pump. \\ | ||
| + | If you follow the path out the engine, the oil is sucked uphill from the sump to the oil pump. \\ | ||
| + | This is why you need to run the engine until the oil is at operating temp before draining it. \\ | ||
| + | Else you'll fill the line on the dipstick, pick up the oil in the sump upon startup and blow out it the breathers. \\ | ||
