35 years ago when Mobil 1 first came out, we had a Mobil engineer that purchased a Motorhome from us. I asked about the NEW at that time syn oil.

BS. I've switched a lot of used engines to Mobil 1 over the years without ever having a problem. That includes a couple of IH Scouts with over 70,000 miles at the time I bought them, a used riding lawn mower, a 1993 Ford Thunderbird, a 1991 Ford PU, my used MH (32,000 miles) and its genset. Never had an issue with any of them.
A 10w oil is a 10w oil whether synthetic or dino.
I'm not going to 100% agree with you on that.
Part of my daily employment is selling lubricants. We are currently working on a full mill change over to the brand we sell.
The issue of synthetics came up, and our factory lubrication engineer flatly said, sometimes synthetics cause seals to shrink and create leaks. Not always, sometimes, and the older the piece the better the chance of leaks.
So yeah, it can happen.
Having said that, I've switched things over myself and never had an issue. In the OPs case it was an older unit and switching back cured it - I'm thinking we know why. :W
