This is my first oil sample so I am not sure what everything means, the mechanic at my dads work said the engine was healthy.

Here we go it was done by Titan Laboratories, their in Colorado.
Oil was Mobil 1 15w-50 with 2,800 miles on it.

Physical Tests
Viscosity-cSt 100C - 16.4
SAE Grade-100C - 50
Fuel Soot - % WT - 0.1 (low I guess)
Water, Fuel Dilution, Antifreeze - none (sigh good head )

Wear Metal, PPM
Chromium - 0
Copper - 10 (a little high maybe?)
Iron - 7
Lead - 9
Tin - 0
Aluminum - 0
Silicon (dirt) - 1

Additives and other metals, PPM
Antimony - 0 (what is that?)
Barium - 0
Cadium - 0
Calcium - 2886 (wow this seems odd? )
Magnesium - 17
Molybdenum - 41
Nickel - 0
Phosphorus - 983
Silver - 0
Sodim - 1
Titanium - 0
Zinc - 986

I will need to get it done again after this next change, this was the first change on synthetic to so some things are probably a little higher then normal. Although I did two changes with Delo 400 15w-40 at 600 and 1,600 before the Mobil 1 went in. I have no other history.

I think you need a control, ie send a sample of the same oil that was not used in the engine.

If nothing was flagged on the report, you are fine.

Zinc, copper, lead, and antimony (sometimes) are used in the Babbet material in the main bearings. If these show up at elevated levels, you have bearing wear.

That oil doesn't.

Max soot is 0.4%, you are nowhere near that.

Iron and chromium are in the block, valves, and rings -- if these show up at elevated levels you have ring, bore, or valve system wear.

I seem to remember high calcium numbers for Mobil 1, but I'm not sure.

Zinc is also present as zinc stearate, a high temperature lubricant additive, so you should always see some. Excessive levels indicates bearing wear, though.

Without doubt you changed this too soon -- the only thing in there is some soot, and since you could go at least four times as long before exceeding the maximum level, do yourself a favor and leave it in for 6000 miles next time, and repeat the oil test. Changing full synthetic oil at 3000 miles is wasting money.

How much did that analysis cost, if I may ask?

I agree.. Mobil 1 at 2800 miles is a waste. I run my gasser for 5-7k on Mobil 1. I run my diesels for 3-5k on Rotella dino.

Peter,

Did you mean to say 4% for Mobil 1?

And, isn't the limit, as specified by M/B, at 2%? This limit would apply to almost every other oil, Mobil 1 and possibly Amsoil, being the exceptions?

Seems I remember calcium was a dertergent additive.

I believe 0.1 is 1/10 of 1%.

This oil change can be your baseline I guess, but run the next oil change out to 5000 miles to MB recommended intervel. If you can, pull a sample at about 4500 miles and send it in and see how it comes out. You may be able to go further or you may just need to change oil and 5000 be your limit.

Hattie,

Did you get a report like this? Or just numbers? If you can read this, note the warnings and such from when I had a problem.
