Hi guys, I am shopping for those 5 qt jugs and noticed Castro edge and mobil 1 fully synthetic..
I have always used mobil 1 but wondering if castro edge is better, is it same as "syntec"?
Also there was a bulletin about switching some of the IS and GS to 5W20 a while back (2007) and then I read the forum now and many members are suggesting 5W30 again, was the bulletin wrong? I am using mobil 5W20 and I am thinking of switching back also, since it feels really thin..

I am currently running Castrol 0-w30 euro formula and have previously run Royal Purple 5-w30 and my observation is my engine feels a little peppier and stronger in the upper rpm's with the RP. I will be going back to to the royal treatment or amsoil next oil change.
