I was having trouble logging in, so my brother was kind enough to allow me to log in under his name.

Any comments on the report? Overall, I am pleased with the results. However, I will also confess I don't know enough about oil testing at this point to pick out any problems. Does anybody have any thoughts on the copper level?

Thanks,
Bobby Johnson

high copper maybe turbo bearing going
change filters normally and keep oil topped off.

Does the beast have an oil cooler? The oil could just be picking up Cu as it ages.

I would say maybe it's time to change the oil now or maybe 200 more hours or so. Over 500 hours - you got your money's worth out of the oil. Pretty darn good IMHO. The viscosity does not change. TBN is killer. Cool.

Did you mention what kind of air filter?
