Awesome I will stick with it. I want to do 10k OCIs with it, even though the owners manual says 5k or 6 months. When do you think it would be alright to extend the OCI? I am still in warranty, but does that matter?
Also, what filters do you like?
I use MC in the Fords, but a quality filter like the high end Fram or M1 will serve you well for 10K. As for as the OCI. If it were mine, 10K wouldn't bother me at all under warranty, but you need to make that call.
