CG = German Castrol? How many miles on the vehicle?

You have a bit of fuel dilution. Silicon is very low so your air filtration is very effective. Were the same type of miles driven on both intervals?

 

[Craigster]

I tow a 8000 lb camper,and a snowmobile trailer quite often. Daily commute 5 mi.Recent temps -10 to 30 F.

 

[Craigster]

Still using original air filter.
Oil -German Castrol 0w/30

All of the wear metals other then copper wear lower with M1 10W30. I would continue to run M1. It is amazeing though how much lower the copper reading was. If we knew for sure where this copper was comeing from I might change my mind a bit butat this point lead, tin, chromium and iron are more important!

Truthfuly it looks like either oil would work just fine!

Maybe the copper is just starting to drop? See what happends in another run.

I am going to assume that the mobil 1 was used in fair weather, and the GC was used in not so fair weather. Give the GC a shot in roughly the same weather conditions, and you might see a better report............then again.....maybe not.

Nice to see these GC UOA's starting to come in. I think we're going to see it's just one of many good synthetics on the market before it's over...

I agree..another run may provide a more accurate comparison.
