Presently use M1 5W30, any advantage to use GC 0W30 ? Why do so many of you like GC 0W30 and what vehicles are you using it in ?

I think GC's reputation was based on a handfull of really good UOA's posted when it first appeared. Now that we have more of them it's starting to look like it's just another synthetic.quote:

You guys say stuff like that just to get me going don't you...you know I can't resist. Yeah I do like the fact that it is green and that people think it smells like gummi bears but I do also think it is great stuff, well engineered, and you make a good point, Paul, it has been used successfully around the globe and in places where L O N G OCIs are recommended and is apparently a staple in lots of shops. I have yet to see anybody address seriously why SLX has garnered SO MUCH discussion. Every other oil addressed on this board has the same opportunity to get people "all gaga"; but they don't...now why is that? If the answer is, 'cause you, Scholte, and Patman, and some of the others keep going on about Elixer of Life and the Green and Green Fairies, etc etc; true...but that stuff would fall on its face if there weren't something about this oil that keeps people interested. M1, Amsoil, Schaeffers, and Redline all have an equal chance...so why don't people get as excited about them? I wish well everyone who uses those oils and hope they get every mile or kilometer out of their engine that those oils can give them...but give me SLX or give me dea...well, that's going too far even forquote:

When GC is used for at least three oil changes it has usually shown better results than M1.quote:

A few of us have run GC in the same vehicles under the same conditions where we had previously used M1 and seen UOA's that were quite similar with no clear advantage to one vs. the other. I don't find this too surprising really. I doubt Castrol has any magicians in it's employ nor are they known for giving us 2X the performance for the same money...
I'll be running 10K drains with it and I'm only 2K miles into the second interval so it's going to take me a couple of years to find out. I just don't drive as much as I used to...quote:
