to be clear, cost is not an issue for me. I do not "cheap out" on any of my cars. Instead, I am wondering about performance issues. Wondering if dino oil would be better at silencing clattering lifters. Jeff provided an answer - oil life is shorter. which is not an issue for me as I would just change it more often. Also varnish build-up - this is a potential significant issue. Any other performance concerns? Sythn seems so thin. I never use Mobile 1 on my 928 for instance. That car has never had even the slightest drip, but one time I used M1 and it leaked. Drained it and went back to my favorite brand of dino oil and never had another drip (although now I use Royal Purple in it with excellent results).
Anyway, my Boxster does not leak, so that is not a concern to me. Instead, it appears to my unscientific observation that dino oil of the same weight as sythn is "heavier" to the feel, or more viscious feeling.
Thoughts?
