The Evaluation of Two-Stroke Engine Lubricants With Respect to Engine Deposit Formation
STANDARD published on 1.1.1979
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

The purpose of this method is to evaluate the tendency of an oil to form deposits in the exhaust system of a two-stroke 50 cc engine.
This method is also able to assess the tendency of an oil to cause piston ring sticking and to form varnish and deposits on the piston and inside the combustion chamber, as well as difficulties with the spark-plug, i.e. bridging and whiskering. The rating of the cleanliness of the components, and consideration of spark-plug difficulties attributable to the oil, make it possible to differentiate between two oils having the same performance with respect to obstruction of the exhaust system.
