Agreed...... All of the above.There's plenty you can do with oil analysis. Namely, selling your car sooner than later if abnormal wear is found. It's also a great bonus if all is well and you're selling your car - additional comfort for the buyer.
Blackstone compares your numbers to averages they have seen from the same engine lineup.I performed oil analysis on jets for 7 years when I was in the Air Force. It can be a valuable tool if used properly. A number of samples taken at specific intervals are best, as there you can see if a trend is developing.
However, without knowing what the wear metals are, where they are located in the engine, and the allowable limits (usually listed in parts-per-million (ppm)), then it's really not of much help.
For example, let's say the report lists 8 ppm for aluminum (AL). Is that good? Bad? How would you know, unless the manufacturer specifies what the acceptable limits are? Unless you have that data, then I feel its usefulness is limited.
Exactly - no prescribed limits for anything.I performed oil analysis on jets for 7 years when I was in the Air Force. It can be a valuable tool if used properly. A number of samples taken at specific intervals are best, as there you can see if a trend is developing.
