 +====== 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. \\

 === Phosphorus === === Phosphorus ===
 Phosphorus is a key component for wear protection in an engine and 1600ppm (parts per million) used to be the standard for phosphorus in engine oil. In 1996 that was dropped to 800ppm and then more recently to 400ppm - a quarter of the original spec. Valvetrains and their components are not especially cheap to replace and this drop in phosphorus content has been a problem for many engines. So why was the level dropped? Money. Next to lead, it's the second most destructive substance to shove through a catalytic converter. The US government mandated a 150,000 mile lifetime on catalytic converters and the quickest way to do that was to drop phosphorus levels and bugger the valve train problem. ​ Phosphorus is a key component for wear protection in an engine and 1600ppm (parts per million) used to be the standard for phosphorus in engine oil.
