Engine Oil: what's best?

[OZVERADA]

I might rob this thread for a sec.

In my LPG veradas, I use penrite hpr10 GAS.

Now for the extra $15, would I be better off switching to the hpr10 full synthetic, as the gas one is only semi syn?

Any thoughts?

I only ever use either Mobil 1 or Shell helix ultra Synthetic oils. No dramas with either of them.
Anyone's thoughts on Royal Purple? Some say it's the duck's guts.

Heard it is the best, also heard it is very over-rated. Wouldn't bother with it considering it's uncommon. Couldn't see even if it was amazing how it could be much better then the proven oils in our engines.
