old man emu Posted May 9, 2010 Share Posted May 9, 2010 When you dip the oil in your Jabiru engine, do you screw the dipstick down, or just rest the threaded bit on top of the filler tube? Old Man Emu Link to comment Share on other sites More sharing options...

Owi Posted May 9, 2010 Share Posted May 9, 2010 Screw it down to the rubber o-ring. And make an extra quarter to half turn to secure it. Not too tight. Link to comment Share on other sites More sharing options...

I believe it is, but it's usually on the lid of the oil cover - well it is on the one I fly. As a general rule - unless stated otherwise - you usually screw/push the stick in to dip it.

Vev Posted May 9, 2010 Share Posted May 9, 2010 Here's a handy file from Jabiru that give you all you need to know about oil dip sticks and oil levels.

brilin_air Posted May 9, 2010 Share Posted May 9, 2010 I just let it sit on top of the threads and if it is on the bottom of the stick it has to be within the level required for the engine once the dipstick is screwed back in, (check it, it works) Brian Link to comment Share on other sites More sharing options...

If you have to add oil and try measuring by winding the dipper home well go and bake some scones because thats how long its going to take before you can get a clean reading. This is an important point because most people mistakenly overfill jab engines (which the motor just spits back out into the collection bottle) and then worry that their motor is using too much oil. Before i was told how to correctly dip the oil i always added to much myself but now the consuption rate on my 120 sits about 35 ml per hour.

jetjr Posted May 10, 2010 Share Posted May 10, 2010 Here's a handy file from Jabiru that give you all you need to know about oil dip sticks and oil levels.Cheers Jack Key here I think is last paragraph in document, "Know your AC" I have older 3300 and After having adjusted dipstick to lengths indicated it is always nearly off the stick - fill it any more it spits it out and/or has VERY hot oil temp. Gets to hundreds of ml per hour use If I leave it just on the tip or at bottom mark max it sips oil at normal rate Link to comment Share on other sites More sharing options...
Modest Pilot Posted May 15, 2010 Share Posted May 15, 2010 I put a double bubble level that you can buy at BCF (used for getting RV and caravans level) mainly to get good fuel dip readings, found that it also helps to get the aircraft dead level fore and aft to get real good oil readings.

zodiac3813 Posted August 30, 2010 Share Posted August 30, 2010 Hi people, I added an extra 15 or so mm to the dipstick so I can run it on the low mark and still measure the level... the only time I fill it any higher is to cross bass strait (fear factor)...
