I sent samples from each engine to Blackstone Labs last week. For the past couple of seasons, I've noticed that my Port engine oil turns darker a lot faster than the Stb side. It also seems thinner and "drips" off of the dipstick. The did not detect a significant difference in the viscosity so it is more of a visual difference to me.
The fuel % on the engine in question is 3.8%, while the other is 0.8. I have no performance issues. In fact....
I was going to post this as a separate question but it's relevant to this post. Thanks to suggestions here, I rebuilt both my Q-Jets four seasons ago (250 hrs?.. I can check) and have literally not touched them since. The hot/cold start, idle, power up are perfect on both engines. How long have you guys gone on a rebuild and/or adjusting? Do you think a mixture adjustment should get this down?
Is the Stb engine maybe a bit too lean @ 0.8 ?
thanks
Bob
