7 October 2011:Technical Manager's comment on 'Dipstick' article in October, 2011 Sport Pilot
I didn't see this article before it was printed.
The article has some errors. Checking the oil in an engine must be performed strictly to the engine manufacturer's instructions:
For Jabiru engines, the dipstick must be pushed right down into the LOCK position to determine the oil level, and other engines are similar.
Always use the manufacturer's instructions.
Having too much oil in an engine can cause real problems, and can cause seal failure and major leaks.
Some engines use the method outlined in the article, but in my experience this is rare.
[*]Please disregard Mr Johnson's comments and use the manufacturer's instructions.
