Here is a report from Blackstone on my sisters 2007 Corolla. I change the oil for her once a year. She drives 14 miles each way to work on 4 lane hwy. The filter was an EaO15k09. Air filter is a Fram and needs to be changed.
I was wondering if I should go with a 5w-20. The oil cap shows to use 5w30 but I know Toyota has stated that older models can use the 5w-20. Thoughts?
Code:
There was some fuel and some silicon present in this first sample from your Toyota 1.8L engine, but
considering how low wear numbers are, we're hard-pressed to call either finding a problem. The silicon could be dirt
due to poor air filtration, but more likely it's from some sort of silicone sealer that was used. Fuel at a trace is probably
the result of operational factors like frequent starts, short trips, and the like. It's not causing any wear. The TBN of 2.4
shows active additive left in the oil since a reading of 1.0 is considered low. Try up to 12,000 miles next time.
