biggest moly value i have ever seen and gc does not have moly. Is moly in LC?

 

[newtoncd8]

Looks like Redline 5W30 has a bit in it for sure!

 

[pscholte]

Stunning performance....but you knew I would say that!

GC - always Thrifty, Brave, Clean, and Reverent. Too bad you messed up the results with the LC.

Why are you changing this oil so often? Except the the usual GM copper, the oil looks great. Leave it in the engine until the oil life monitor tells you to change it. It's probably still good, but you've got a warranty to protect.

Leftover from the over 550 ppm Redline has in it .... typical Redline remnant issue

Nothing wrong with using LC. In fact a lot of people highly recommend it here. It just would of been nice to see how the GC would of done on it's own.

Hey with all the Moly in the Redline, I wonder if it would be good Honda breakin' oil, since that's how they come from the factory, loaded with Moly.

 

[Alex D]

Honestly from what I have seen I do not believe that the GC without LC would have done any worse. LC in my opinion is a nice supplement to keep the engine clean, but does not reduce wear on lower mileage OCIs at all .. maybe it helps when you stretch your OCI, but I'll never get there.
