Now, if it spelled burnt or felt gritty, that would be a totally different issue, but color? Not an issue. Now, with a diesel engine, it will get looking nasty quicker, but still works fine.

I've been changing at 4k past couple of times expecting to recover from the '11k interval' junk that previous owner was stuck to ... hows the idea of little sea foam before the oil change ?
Actually at the bmw westmont's parts department today I saw they're selling Amsoil Engine/ Transmission Flush - says put in 10 - 15 mins before oil change .. I was really surprized to see Amsoil in a BMW dealership |
I use 10k intervals and send samples to blackstone, while my car was under warranty I did 15k intervals. I'm Fbo. Samples come back looking great at 75k miles... They are posted up here if you want to search...
