Contact Contamination During Fluid Delivery...
Possibly the most overlooked cause of mechanical failure, reduced
fuel efficiency, shorter oil service life and loss of engine performance.

Below are statements taken from articles written by professionals in the lubrication field.

"John Deere has stated that the greatest enemy of a well-maintained engine is the funnel used to add oil to the crankcase. Grit introduced into the oil through a dirty funnel will have an opportunity to grind on the oil pump's internal surfaces before it is removed by the oil filter."

Lubrication: system components

"Fluid contamination is another source of trouble. Common contaminants are external dirt, spent friction material and engine coolant. Dirt often enters a transmission when fluid is being added or checked. It can come from a dirty container or funnel, or a dirty rag used to wipe down the dipstick."

"Lube oil contamination is a primary reason for engine wear. The wear processes promoted by oil contamination lead to diminished fuel efficiency, shorter useful oil service life, reduced component life, and loss of engine performance."

"Studies have shown that 70% to 85% of equipment failures are self-induced, meaning that maintenance practices and processes are directly responsible for the failures."

"When adding clean oil ensure the container, funnel, pump and area around the reservoir is clean."
