Just received my oil report

I drained all the oil from the bottom, and replaced the oil filter. I refilled with ~9.3 quarts.

Admittedly, I was a little confused when filling out the form. From the time of the last oil change I added zero oil. So, now their comment makes sense.

Thank you for clearing that up for me.

I can't comment on the numbers as I've never had an analysis done.

I agree the that that the 9.3 liters comment was just that, a comment based on what you had filled out.

I don't know how long you've had your car but my way of refilling is to do a change (incl. filter) and put 8.5L in and then drive home (~4 miles). After the car is cooled, I add whatever quantity was necessary to achieve a level between and half full and completely full. Just don't want to overfill....

I'll try that approach. I just wham-bammed... put in 9 quarts... checked the level... kept adding until reaching 9.3 (more like 9.4-9.5) until it hit the mark. I did wait for the oil to settle, maybe an hour. My next change will be more accurate. Thank you for the tip.

You have a baseline now to compare future reports with. If something starts to deteriorate, it should show up here.

EXACTLY as the previous poster said........an oil analysis is only useful if done each time the oil is changed. It's "value" is as a "trend report". As previously said, now you have a base-line from which future reports can be judged against.

Personally, I don't see much of a benefit in an oil analysis. I know large fleet companies (trucks) typically do them as a way to track their fleets. When I owned an airplane I used to do them, but after I had a cylinder failure with NO indications or even hints from my previous years of oil analysis I stopped.

The best advice I could give you would be to buy an oil filter cutting tool and cut open your old filter, stretch out the paper and look for any metalic pieces and possibly use a small magnet on any pieces you may find. Remember.....ALL engines "make metal" it's just part of the wear process and most of the time it's perfectly normal.

I might consider an analysis every 3 oil changes, keeping an eye out for anomalies. Thank you for the advice. I did cut apart the filter... stretched it out... looked for metal, saw none... ran a magnet, nothing. For the most part, the filter had zero debris causing me concern.

If you recognize any aberrations in any of the numbers, please advise.

Cheers!

Magnesium a little high?
