This analysis was not as "interesting" as I thought it would be.
Car is driven about 80% highway and 20% creep and go on what we call a freeway.
This is the end point of the third full Redline oil change cycle. This will be the final point of the baseline.
Fuel Power was used during the period as a fuel additive.
The MAF failed a second time about 7000 miles into the interval, and the result was more soot. The timing was also about three degrees retarded as compared to the last analysis. The result is a lot more soot, and the oil has thickened as a result.
The timing belt was changed. The process requires that the cam be locked using steel locking plates. The top of the motor was open for several hours. Dust caused the elevated Si levels, and ground down some of the innards. The cam seal and vacuum pump seals were replaced, causing more stuff to get into the oil.
The cam lobes were examined at that time. No detectable wear was found at that time. No deposits of any kind were found on the valve train, or under the valve cover.
Overall Red Line seems to be doing a good job of keeping things clean.
OEM oil and air filters were used.
