Mobile 1 Full Synthetic 10W30, 7072,04 Mits Lancer

[Jellyfishian]

I'm new to to the forum and to oil analysis in general. This is my first run on full synthetic I was previously running a Mobile 1 Synthetic Blend for about 3000 Miles at a time. I was under the impression I could go a further than 7K on a change but as of now I'm glad I changed it when I did. Any advice? My next change will be at 5K with the same type/grade oil. Using the same type of filter (OEM Mitsubishi).

Tips, comments, advice greatly appreciated since I am so new to all this.

That high Al is weird - nothing else on the report indicates what caused it (ie., no excessive silicon or insols., viscosity still in spec.).

More knowledgeable members will hopefully be able to help you out!

Alu could be bearing issues.

Try not to stress your engine too much (esp. the big end/crankshaft bearings part) over the next round of OCI and see how the reading goes.

BTW: most engines produced during the past 10 yrs are of splattered aluminium type and no longer babbitt bearings.

Q.

 

[Jellyfishian]

I will try not to stress it out so much this time around. The problem is its just a fun car to drive and push it to its limits.

Good to see another Lancer man on the board!

What's your mix of driving and do you really rev the engine? Those are the deciding factors in establishing an OCI.
It's a good thing you changed your oil out when you did and decided to do a UOA.

The high Al is due to new improved formula of M-1--instead of high iron, you now get high aluminum-IMO either way, you are skrewed using XOM products

A good 40% of this change was highway, however most of it was not easy highway very mountainous = Higher revs.

City driving I do have my days where I have fun with the car, but normally I keep the revs down and shift around 4K RPM max.

Interesting to know, thanks! I'm not even going to open this can of worms but I'm researching what oil would be best for my driving habits.

Which oil is that? There is no synthetic blend oil in the Mobil 1 product line. Perhaps you're referring to Mobil Clean 7500?

I think Steve's post was more tongue-in-cheek than actual fact.

You are correct my mistake that is exactly what I was using previously.

I understand but still might be something I will research.

There is not enough data there to determine if the OCI was too long. 12 PPM of aluminum particles is not going to significantly harm the engine from abrasion.

A TBN measurement would help determine a proper OCI. Much better yet would be two UOAs, with TBN, on the same oil: one at 1/2 the mileage interval and the other at the end of the OCI. Then the wear rates could be compared. If it increased considerably during the 2nd half of the OCI, that could mean the oil was run too long.

What OCI does the manual recommend?

Aside from aluminum and some slight expected fuel dilution (being a turbo engine), this report looks stellar.

 

[daman]

Besides the AL everything else looks good for the mileage i'd try another run and see what shows up,could have been a fluke.

The iron seems high................................................

Hi,
Jellyfishian - This is a good UOA

Using Blackstone Universal Averages the Aluminium is consistent!

On any account Al is not a worry - and the viscosity's movement down isn't either IMO

Thanks Jag this is helpful, so if I understand you correctly to get an estimate to see if I ran the oil to long my next change should be half the amount that this test was run.
OCI from the manual says 3K in severe conditions and 7K regular (I think I'm closer to severe in terms of location and driving habits).
Also this is not the Lancer Evolution, it has an N/A 2.0Ltr

I honestly would not run the next oil analysis any shorter. There is nothing wrong with this one. Go the same length of time and compare the results. Make sure you get the oil very hot before draining..like at least a half hour run.

You don't need to immediately drain it and burn your self but getting it good and hot immediately before the drain will insure that all of the water is cooked off.

"The viscosity was low, reading down to a 5W30 range"

How does a 10W30 improve it's cold flow properties after 7000 miles? That doesn't make any sense.

Sorry, I mistook this for the turbo engine which changes what I would have said before. I now think all you should do is run to 7K miles again and just add a TBN measurement. If it comes back high enough, you won't have to do that again unless something changes (like going back to dino oil, change in severity of service, etc.). BTW, a benefit of Arizona climate is it reduces damage to oil from cold engine operation. That can easily do more harm than operating in hot weather if the oil is an oxidatively/thermally stable oil like Mobil 1.

I no longer advise it, but what I meant earlier was take a sample at 3.5K miles (do not drain it) and then take another when you do drain it at 7K miles. You'd test the same oil but at different times.

12 ppm of AL doesn't seem to be out of the ordinary.
