20b engine oil. What do you use?

I need to give my oil a freshen up and wondered what you guy's are all running. Currently I am on a 10w40 semi synthetic. So the question is do I stick with that or should I be looking at going mineral or Fully. I am sure there are views on each? Some may say change the grade?
Let me know.
Majority rules!

Cheers
Lee

idea is turbo rotaries run hot, so you want to put in thickest oil you can find. I personally use mobile synthetic 15W/50 and I fully premix.

Another thing to note is don't use synthetic if you didn't delete OMP. As for regular nonsynthetic oil, any 20w/50 will do.

I am running premix too. So could go fully synth . Maybe a race oil. 20/50 sounds crazy thick? I thought they are booked as 10/40 or 5\30? Would like to here some more views on running a thick oil though and going fully sythn maybe. Cheers
