Recently, a lot of fuss has been made over this oil, with most of the UOAs being run in Honda Civics. I was curious how Civics fared in general, so I decided to do a little “research” into the analysis results we have at our disposal. Since all the Civic German Castrol UOAs I could find only go back about 10 weeks, I decided to only view the other UOAs that far back as well (the exception being Redline, which was about 12 weeks out). Here’s what I came up with:
N/A = an unknown dino 5W-30
M1#1 = Mobil 1 10W-30
M1#2 = Mobil 1 5W-30
Ex = Exxon 5W-20
RL = RedLine 5W-20
Obviously, the GC is a good product. But I guess I don’t understand why it’s considered to be any more than that. Can anyone explain it for me?
For reference, the other oils are:code:
