My sisters car. She comes down to visit a few times a year and one of them is for me to change her oil. This run was done just as she got to the house after a 2.5hr drive on I-40. She replaced the air filter about half way through this oil change and it ran an Ea15k09 oil filter. Not oil added, still on full when I checked it. She drives about 14 miles each way to work on the interstate.
Code:
This sample looks fairly similar to the last sample since there were only minor changes to wear metals. Silicon
is still a little high, though it did come down somewhat since last time. We doubt it's an issue, because if it were, metals
would be much higher than what you're seeing here. More likely it's an additive or sealer or something. If you haven't
checked your air filter in a while you could check it just to be sure, but really, it doesn't seem like an issue. No fuel,
water, coolant, or other contamination was found, and the TBN was fine at 2.9. Try 11,000 miles.
