I just sent my oil from my first 3000km on my MR away for analysis and it failed on 4 key points. I got my car with 28km on it and i fully believe that this is the time when the most damage/wear in is done. I did not change the oil when i got the car as im pretty sure mitsubishi would then say it was my fault for contaminating the oil, wrong type, in correct procedures e.t.c. They did the oil change at 3000 and also supplied the warm sample to me (also to avoid them saying i sent in a false sample). It failed on a high copper content, high silicone content and also heavy contamination with fuel. Not sure where to go from here next. I doubt mitsubishi will really care but i think if i at least have it on file then it is recorded if something goes badly wrong in the future. I got them to type into the first service report that they took the oil sample as well.
I will let you know what they say next week.

 

Very possible its because it was the break-in oil. I say just drive the car and get your next change analyzed and go from there.

 

yeah do it on the 3rd oil change.

 

Yee the wear items i am not to concerned by and the next analysis should be interesting. Heavy fuel contamination does worry me though as im sure your aware this really reduces the properties off the oil. Also i was wondering where all my fuel was going

 

How was the sample collected? Did you see the procedure?

 

when the engine is assembled there is assembly lubricants that break down with heat after the engine warms up for the first time and mix with the oil in the pan. That should account for the silicone. The rings will not seal to OEM specifications until the break in procedure in finished on the engine dyno at the factory. That will account for the gasoline content being elevated. The high copper content is from the valve guides and various brass bearings being broken in (bronze= copper & tin).

p.s. do an analysis after your 3rd oil change or 3k miles and see what your % contaminants look like.

 

Ignorance is bliss. Unless you are trying to do failure trends on a fleet of engines, I think doing your own oil analysis is just like knowing when you are going to die(but with less accuracy).

that, and there is way to much to interpret-in this case, I agree to resample on the next oil. BTW, you already know the car runs super rich, but the metals are harder to explain.

 

Unless I'm reading it wrong, he bought it with 28,000km's on it. Long past the break-in period. Fuel in the oil can come from several different places. Up through the head, passed the rings..
To the OP:
From what you write, the motor sounds like it's really tired(no duh..huh?). May have been thoroughly flogged by it's previous owner.
One thing's for sure. You definitely crossed your "T's" and dotted your "i's". If this were to end up in court, I don't see how the dealer could refute it. Of course the lab's gonna need to be credible, and the sample will need to be proven that it came from your car.. A leak-down test would be a really good idea at this point. It could corroborate the lab's finding(s), and could give you a really good idea how sick your motor actually is.

 

You are reading it wrong. It's 28km. Not 28,000km.

Like most have said send in a later sample of oil, while following the same procedure as before, so Mitsu can't deny anything.

 

28km....not 28,000 km.

 

I'm at 20,000 miles and now you guys have me worried that something may be wrong with my car.

How do I go about getting this "oil analysis?"

Thanks.

 

Honestly, it is not necessary. There are other cheaper things you can do if you want to check to see how "healthy" your engine is such as a compression test. The only time I will ever pay for an oil analysis is if my engine fails, and I can't tell what the failures cause was.

 

There is a company Blackstone Labs you can send a sample to they will give you a full analysis fairly cheap. A great bunch of people over there

 

the analyst company will send you a vial. when you change the oil, catch some of the pouring oil out of the draining oil pan. (about mid way through the draining process)

send in the vial and wait for their findings.


OP.... yeah I'd have the Dealer place that info in your file. If the bad thing happens you have a paper trail.

 

Fuel contamination. Yeah, like from the 9.8 AFR programmed in the ECU?
