RE: Is this normal?
I'm glad you stated that it was your opinion. I see tons of engines that are still running today that were made back when castor was all there was. As for the Saito, you're right ... they don't like you using castor in a lot of ringed engines.That doesn't make it illegal. I happen to like castor. I would never use an all synth blend that has the potential to flash. I care about my bearrings.
