Woofa Express, maybe a misunderstanding? Also aviation engine oil is slightly alloyed. Old Lycoming etc. may not use heavily alloyed HD oil due to combustion residues. But even a lightly alloyed engine oil gets dark in 100 ml.

I worked in the oil industry. If you tell me the exact oil name you've filled in, I can probably say more.

Yes Werner, I'd like to have your comments, however let me write, tomorrow, and I'll give you my thoughts and reasons and more details on oil types. cheers, gary
