Posted: Mon Feb 11, 2008 1:50 pm Post subject: Engine Oil Change

I just changed the oil in my Jab 2200A engine, and  made an interesting observation.  My engine is in a Kitfox IV with tail  wheel.  After draining the oil in the 3-point position (over night), I  raised the tail so that the A/C was level (flight position).

 I did this to recalibrate the dipstick.  After  going to the level position, I got 3-4 oz. more oil out of the engine.  I  don't know if anybody else has observed this, but I thought it would be worth  noting to the group.  In the future I will always drain the oil in the  level position.

Why did you want to recalibrate in the level position? I recalibrated  

mine in the tail down (taildragger, too) position, because that's how  

it's going to be when I check it.

Lynn,  I wanted to recalibrate my dipstick,  because when I first did it, the dipstick tube was not in the proper  position.  When I first added oil to my engine, I calibrated the dipstick  for the 3-point position.  Then when I ran the engine, I had an oil leak at  the base of the dipstick tube.  I found out the dipstick tube was not  seated all the way down so that the O-ring was engaging.  When I pushed the  tube down and tightened the setscrew on the dipstick tube holder, it would raise  the tube about 1/4 inch.  I fixed that problem, but never recalibrated my  dipstick.  

  

 My max oil level in the 3-point position is at the  bottom mark of the original dipstick that I assume was calibrated for the engine  in the level position..  Where is your max oil level mark?  I could  use a longer dipstick, are there any to be had that will fit.

I "borrowed" someone else's idea and using a small pin punch, drove  

the dipstick tube down into the knob about a quarter-inch. This makes  

the stick penetrate further into the oil in the sump. Or you could  

just silver solder a short extension onto the original dipstick.

With this new position of the original marks, I use the center mark  

as my oil level.

Basically what you should do is to add the amount of oil that the  

instructions recommend, like say after an oil change, then start the  

engine, let the oil circulate and fill the filter, lines etc., then  

let it sit for several hours. Then make a mark that shows the level  

at that point. This is the level of oil that they recommend. I've  

found that if I add 2 qts and 14 oz of oil after an oil and filter  

change, then start up, shut down and let sit, that is my oil level.  

This reflects about what Jabiru says the oil capacity should be.
