Ken,

I replied earlier but the reply went into the nietherworld.

What I said was it appeared that the last two oils listed are synthetics.

Ken, Esso Ultron used to be an excellent oil. It may now just be a repackaging of Mob1. I'd use it if it is the stuff we looked at previous to EXxon gobbling Mobil.
Can't get it in US or Canada anymore.
