August 3, 20232 yr Im confused with the oil. On the oil lid it says SAE 50, SAE 30 and SAE 20. But in the tablet where I can change it, they are called 100AW, 20W-50 and 25W-60… So im confused wich one corresponds to the type marked on the oil lid…?? Edited August 3, 20232 yr by Kaboki
August 3, 20232 yr The Commanche is an old aeroplane designed before we had multigrade oils. Put in 20W-50 and you'll be fine.
August 3, 20232 yr SAE is a system classification, denoting viskosity (higher classification means thicker oil) Your example of "20W-50" is a type of multigrade oil where W stands for Winter I believe. All manufacturers have their different flavors on this. l use Aeroshell W80 on our lycomings irl and that is supposedly equal to SAE 40. EASA PPL SEPL + NQ / CB-IR in progress MSFS24 | X-Plane 12
August 3, 20232 yr Further details if interested…. 100AW is used when flying in hot environments. 25W-60 is best for mild to warm climate. 20W-50 is best for mild to cold climate. The 25W and 20W are good all-around oils. Using North America as an example, during the summer, I’d use 25W and in the winter, I’d use 20W. (Maybe switch to 100AW if you were flying in that southern US heat dome). Edited August 3, 20232 yr by Danno Typo
August 3, 20232 yr Author Ok, thanks, but the lid have info about tempratures, so it would be nice to know exacly e.g what SAE 50 equals to in the tablet,,, your answers only confuse me more… in a form like this: SAE 50=<from tablet> SAE 30= SAE 20= Edited August 3, 20232 yr by Kaboki

The original Comanche manual I found (Comanche PA-24-180 PA-24-250 Owner's Handbook (pipercomanche.info)) just mentions the same as on the oil lid. I found some useful info when searching for suitable oils for lycoming engines: DATE: (lycoming.com) If you combine the tables on page 1 and 2 you might be able to come up with a suitable oil for the environment that you are flying in.

August 3, 20232 yr Author Ah ok, anyway, learned a a lot about oil from this thread, so thanks guys. Think Ill will be okay with 20W-50 (suggested by DD_Arthur) as I mostly fly north america, UK and Norway.
August 3, 20232 yr Hi , I admit i did not read it all but do A2A simulate olie vs real environment in MSFS? Michael Moe Edited August 3, 20232 yr by Michael Moe Michael Moe
