Severian (OP),
Having taking both my old Porsches to Synthetic from dino (neither engine has had a full rebuild (still have used seals). Engine leaked as a result. Now I'm converting back to dyno until I do a full engine rebuild with new seals then I'll go to syn.

I go about 6,000 miles. Modern oils can easily do more, but for $40 it's not a big deal to me to just do it every 6-8 months or whatever it ends up being. I run M1 15W-50 full synthetic. I'm not going to preach this is the best oil...your oil is your decision, but in my area, it's like $22 for 5 qts so that's what I run for a street car. I change the filter with every oil change, mostly because I have a ton of them in a box and why not. Car burns no oil and the leaks are nothing to write home about.
