I'm seeing high-ish copper in my '03 BMW 330i as well. I've been running Amsoil 5w40 "Euro" oil in mine with a 7,500 mile OCI. I just bought the car last year so I only have two changes on it. My oil reports look nearly identical to yours in terms of wear metals, even given the longer OCI...

Thanks for the input, I will try a 40wt next time.

Yes, it is a generic Mazda 3 manual. The manual is inconsistent (I am odd in that I always read the owner's manual cover to cover on all my vehicles) - some places 5W20, some places 5W30. I am told that the early cars all spec'd 5W20 in their manuals and there was a rolling change to 5W30 (for...

My manual actually calls out 5W20 as the recommended oil in a few places. It was only after reading up on these cars that I started using 5W30. The recommended interval is 7500 miles but it doesn't seem as happy with that. It's my wife's car and she puts about 2,000 miles a month on it, mixed...

First analysis shown was the original oil, second was Amsoil 5W20, and everything after has been Amsoil 5W30. Seems low in viscosity to me. And the iron seems high. Any comments? Thanks!

The car has had a cat-back exhaust on it for the last 20,000 miles. The stock cat-back rusted out at the hangers so I replaced it. Other than that it is stock except for some suspension upgrades. In the time that I used the 0W40 (since 100,654 miles) I have done 10,000 mile changes and the Fe...

Thanks, even though these 1.8T's are known as sludgers I haven't seen anything to indicate this one has any problems. We are reasonably hard on this motor and it's never been opened. Original turbo as well. Nobody has any ideas about the sodium?

Yes, this is 5W40 turbo diesel truck oil from Mobil 1. Previously I had been using Mobil 1 0W40. 152,000 total miles after this change. Oil was in service for the period 1/24/09 through 7/28/09, approximately 6 months. Zero quarts added between changes. I use Purolator PureOne oil filters...
