Hi Don,



Here is a website for some good basic info on different oils. It will fill in the gaps of why's and why nots. It will tell you what the additives are for and who's oils seem to hold up better under certain conditions. This is only one article and it was done for Amsoil, but shows about 20 different oils. I like this article for learning about the basics because it is easy to understand for most people. Look at the foaming properties and what shear additives do for oils. After you read about shear additive you will understand why Rotax doesn't really want a car oil unless it is all that is available. 

Just read the article and make up your own mind.

The reason for not using full synthetic with a lot of 100LL (more than 30% of the time) is that synthetic will not suspend the lead and it will fall out of the oil solution and collect in palces like the oil tank and different parts of the engine. A little use of 100LL with synthetic is ok, but with a more steady diet of 100LL you should be using semi-synthetic. Synthetic will be a better choice than regular oil for the Rotax. I don't know enough about Kendall to comment, but maybe this article will help you make some decisions. 



You don't want an "Energy Conserving" (doesn't mean full synthetic) oil like some car oils as someone mentioned. Motorcycle oils are not "Energy Conserving". Bad for clutches and our gearbox, makes them slip.

Gents....I AM FIXED!



AND speaking of Lockwoods 912 schools!!!!...did you read the short article in last Kitplanes about the author attending the school, and giving some highlites of the advice there??.....WEll he gave me the final clue.

It was a short mention of the 2 different choices for oil return line location. And remember me telling you guys that I took out a plug towards the rear of the bottom of the crankcase????and a quart of oil ran out????

The author mentioned that in a pusher installation, the plug on the bottom of the crankcase closest to the gearbox will be the lowest on climb and in any nose up attitude, and the opposite end will be lowest on a tractor engine...and you are to use the lowest one. WELL, that plug I took out was where the banjo bolt return line was supposed to be installed!...mine was at the wrong end, causeing alot of oil to just sit in the crankcase, and it was likely sucking air every time I had the nose up...INcludeing sitting on the ramp at rest.

I changed the location...test ran it for 10 minutes...then 2 or 3 touch and goes...temps stayed down, inlcudeing one run clear around the patch at WOT. Then stopped...added some fuel and flew to an airpark 40 miles away and landed...grabbed a Ice tea...and flew home. Oil temps steady at 210 all the time. WAHOOO!

I thank all who responded and helped me think this thru!

Great news Don.

 neck points on your bird Dave? On mine, it points at 9 oclock from above, 

 which

 means in a 90deg left bank, it points straight down.


	


Mine points at 9 o'clock, the tank is on the left hand side of the cowl. 

Keep in mind that even in a steep left turn, the force is towards the bottom 

of the plane so the oil in the tank should remain level (relative to the 

tank). So unless you are slipping, the oil shouldn't come out of the tank 

vent. Have you ever seen the video of Bob Hoover poaring a cup of tea from a 

jug whilst rolling the Shrike Commander. Even inverted the tea flows from 

the jug into the cup.

Hi All,



So who all read the article on oil? Did you find it informative? Something to at least base your ideas of oil properties.

You don't have to be an Amsoil fan, but it does explain what oils do and why.
