1) Essentially yes, but the base stock is certainly the same ut we arent sure if the addiitves are exactly the same yet.What is certain is that they are roughly similiar.It appears bottling is still done at diferent locations, even though much refining is shared.2) I think GL5 is sufficient by itself and thats all I've used <but> some smart people her disgree and Q45tech always adds a friction modifying additive.If I remember when I refill ,I will likely do it as well, but last couple times I forgot and am not too worried about it, but it pays to follow Dennis' guidance on those matters.3) There are diferent clutches many of which require completly diferent fills. from GL4 to 10w-30 motor oil to brake fluid. SO it really depends on what your manufcaturer tells you, its not like reciprocating internal combustion engines that are all roughly similiar.4)GTX is fine, I actually like Chevron Supreme even a bit better due to a group II+ base stock used. And its cheaper too, but you cant go wrong with GTX for sure.As for your winter fill. its due a bit to your local climate ( your location isnt shown) but the rebadged SLX is a great choice for sure, also the M1 0w-40. The redline 10w-40 wouldnt be my first choice from RL, I am pretty sure they make a 5w-40 as well, which would be my winter oil pick, if the winter isnt too harsh.
But a northern winter, the best fit would be SLX 0w-30 or M1 0w-40, IMO among off-the-shelf oils.
About you last sentence I am not real clear on it you are asking me what a KAAZ fill should be? I dont know enough about those difs to make a competent recommendation...:oface
