My comments:
Oil is mix of 4qt Maxlife blend and 1 qt Synthetic Maxlife, both 10w-30.
Top off oil: Delvac 15w-40
Additives: ARX,Lubro Moly MoS2
This OCI started in July, after I removed valve covers, manually cleaned out sludge that I could reach. All gaskets were changed out, and I used some silicone liquid gasket to glue new rubber gaskets to covers. That is where silicone came from probably. Also most OCI I had K&N drop in filter.
Oil filters used: 2 ST, 1st was swapped out at 1500 miles and inspected.
Looks like engine chewed up TBN pretty intensive, even there was 2 qt of fresh oil?
What's start up TBN of Maxlife and Delvac?
Comments from Blackstone:
"This Toyota isn't wearing quite as well as we'd hope. Averages show normal wear after about
4,700 miles on the oil, so wear should have read lower. Aluminum usually comes from pistons, iron from
steel parts (shafts and cylinders) and copper is from brass/bronze. Silicon is high, and that might be causing
some of it, so check your air filter. The TBN is fine at 2.9 since 1.0 is considered low. Our suggestion is to
stick with 4,000 miles for now to see if silicon and wear improve. Hopefully they will, and at that point a
longer oil change should be just fine."
