Your oil analysis looks good. If you could provide some additional information it would be easier to offer informed opinions. Please tell us:



1. What air filter?



2. Brand and weight of oil in crankcase prior to this oil change?



From what I see, your Delvac 1 is serving you well. Your TBN remains high, your air filtration is excellent(6ppm silicon).



The viscosity(13. 57) is at the low end of the 40 wt. scate. It is just over 15 centistokes out of the bottle for new Delvac 1. That is why I am curious what oil you ran prior to this.



There is certainly nothing to worry about here. All your wear metal numbers look fine. Another 10,000 miles on this oil would be no problem. Great performance from a great product.

1. ) Air filter - K&N in stock airbox

2. ) Prior oil - Exxon elite xd3 (semi senthetic) 15-40



At 53K I changed to xd3 15-40,

At 57,327 I changed to Delvac 1

At 60K I changed the filter (#3894) and topped off w/Delvc 1

At 69,760 I pulled oil for analysis

At 69,811 changed filter (#3894) and topped off w/Delvac 1



I wanted to go ahead and leave the oil in until I got the analysis back and got some input on it.



What do the Boron, Magnesium, Calcium, Phosphorus, Zinc, Iron #'s mean.



Thanks for the help

The Boron, Magnesium, Phosphorus, and Zinc are part of the oil's additive package(anti-wear and detergent). The Iron is wear metal primarily from cylinder walls. Your iron number is just fine for the miles on the oil. Nothing to worry about.
