Analysis:

We can see you are inching up your oil use

intervals and the remarkable thing is, your

wear is showing little effect from the changes.

Comparing the wear in this oil to the metals in

the universal average column, you can see how

well you are doing at 57,869 miles. The

viscosity was a little high for a 5w/30, but not

so high as to hurt anything. There is a little

concern with the higher sodium, which sometimes

shows traces of anti-freeze getting into the oil

sump. You will want to monitor this, just in

case. The TBN was 3.4, showing plenty of active

additive.





My comments:

Changed the air filter and PCV valve halfway

through this interval. Overall, I'm happy with

this report and I plan to go to 9,000 miles on

the next one. This is the second analysis in a

row that shows elevated sodium. I would be

worried, but wouldn't there be a corresponding

increase in potassium if I had a head gasket leak

or something? I'm not worried yet. I'm

surprised the wear was so good, since I'm really

hard on the car and I drive it maybe 70% city/30%

highway, and those highway miles are short ones,

less than 10 miles. My foot is made on concrete. Any comments are welcome.

Excellent

Nice to see a great report w/o changing brands or vi after

This has got to be one of the best reports to date! The oil handled this engine and interval without a problem and could have gone even longer.
Outstanding!!!

I would go the same interval next time bc of the sodium. Normally there is some potassium in there but that may be a function of the anti-freeze. Note the higher silicon and the higher thickness=signs of anti-freeze leak. But this may be an anomaly its a very very small leak. I just wouldn't risk goin further.

Otherwise a great report.

It looks like Mobil increased the calcium content of this oil.
