I just got results back on Mobil1 5W30. The car is a 02 VW Jetta with the 1.8 Turbo motor. I had planned on pulling the sample at 15K but ended up at 17,640. I am a long distance comuter of 128 highway miles each way daily and the total mileage is 102,466. I have used the search but the vast amount of information can be overwhelming. I will surely learn a lot from this site in the future. I was recommended to this site from a member of the VWVortex, he said the calcium level looked to be of concern as well as the copper.The results follow. Also where might I find the TBN of Virgin Oil and do most of you test the TBN.

Iron 18 ppm
Chromium Nickel Aluminum 5 ppm
Lead 4 ppm
Copper 30 ppm
Tin Silver Titanium Silicon 15 ppm
Boron 121 ppm
Sodium 22 ppm
Potassium Molybdenum 72 ppm
Phosphorus 884 ppm
Zinc 1116 ppm
Calcium 3570 ppm
Barium Magnesium 44 ppm
Antimony Vanadium
Fuel % Volume T/S % Volume 0.1
Water % Volume Vis. CS 100' C 11.1

Thanks for any insight as to what the results mean in laymens terms.

Excellent. I would say that the highway miles (over 250 per day!) are easy on the oil.

You went 17.6K miles on the same oil in a turbo and those number look really good. How much do you boost?

Not sure why your bud would be concerned with the Ca, and Cu isn't that bad considering the miles.

Wow, I'm no expert but for 17k on the same oil and filter, those look like excellent results. No oil added in all that time?
BTW, why didn't you get a TDI for that long distance commute. Would have saved you a few bucks on fuel and last longer as well.
 
I'd also check into the air filtration system, the silicon is a little on the high side. That may make a difference in your iron and copper readings.
 
Thanks for the response guys, I already learned something. I had no idea what the calcium was for.
To answer the questions. This is a gas Turbo motor and I am running the boost at 1.35 bar, there was no makeup oil added and the same filter as well. I use a Mahle OEM filter. I wish I had gotten the TDI, probably next time I will. As far as the High Silicon, I do live in the Mojave desert and we have frequent windy periods in my area that kick up a lot of dust. I am running a washable Accel panel filter, maybe I should clean it more often.I beleive the air filter was in for 40K.

Thanks again for the help.

I don't even consider 15 ppm Si high - 17K miles!

M1 in the Mojave desert, 20 psi boost, 17K miles and the viscosity changed up just ever so slightly. Pb=4, Al=5ppm. Incredible. Almost unbelievable. Too bad no TBN.

What lab? Can you post the real report?

At these levels, the Ca is more than a detergent. Mobil is overbasing Mobil 1 now and the calcium acts as a AW/EP additive—a very effective one, judging from your excellent results.

I'd love to see you run Mobil 1 0w40 and see how it compares.

Schnoe;
His Silicon readings are unbelievable! At 15 ppm of Si in more that 17K miles equals to .88 ppm/1k miles. That is perfect filtration....at least I haven't seen any other UOA looked this good, except for Ken4's Camry, which I believe only had 3ppm in 10k.
I would not change a thing, your routine seems perfect for this car.

I will try and post the actual results tomorow, they are at home. The lab was Analyst's Inc. in Oakland. Also the ambient temp in my home area has been 100+ for the last couple of months but the car is driven to the Ventura coast area daily. Talk about two different climates.

Abolutely great numbers. The copper could be coming from an oil cooler (do you have one??) also could come from the crank thrust bearing or maybe oil pump. Keep an eye on this.


In an oil analysis the real key things are the wear metals: Aluminum, Iron, Lead, and copper. These values get higher the longer the oil is in there. Iron is usually 2 or 3 per thousand miles (parts per million -ppm) . Lead, cupper, aluminum are usually much lower - maybe 1 ppm per 1000 miles. Silicon is dirt plain simple- it whould be maybe 2 ppm or so per 1000 miles. If its too high the wear metals will go up.

These are oil aditives:
Molybdenum 72 ppm
Phosphorus 884 ppm
Zinc 1116 ppm
Calcium 3570 ppm
Barium 10 ppm
Magnesium 44 ppm

If you see high sodium and potassium that could be a head gasket leak. The oil will get thicker if these are present and engine wear will go up.

The last few are water, solids, and fuel-naturally you don't want a lot of this.

Frequently they give a TBN which is total base number. If its very low (like 1.0) the oil is shot. Sometimes they give glycol-which is very useful..

The last number is the viscosity or thickness of the oil- a 30 wt. oil should be between 9.3 - 12.5 Centistokes cSt. Higher is thicker.

This is very brief and oversimplified-hope it helps 'ya

I think we have the new King of All UOA's on this board. Speechless.....

I just uploaded the actual report image to my webshots account, I will post the url in about 30 minutes, the photo site makes you wait 30 minutes before they can be seen publicly. And no there was absolutely no makeup oil added and the dipstick showed a full sump right before the drain and filter change.You guys are great, I have learned so much in less than 24 hours it's unbelievable. The picture will be in my public items under oil anaylisis. You will have to view full size to be able to read it. My Webshots Account

I must admit I'm very impressed with them lately, but I still would not recommend their 5w30 or 10w30 for use in an LS1 or LT1 V8 engine. I'd recommend their 0w40 though.

As I mentioned in another post, I'm most likely going to switch my wife's Civic back over to M1 5w30 when I finish up my supply of Royal Purple.
 
coolvdub ,

Great report by all means! I wouldn't change a thing - this oil is obviously working very well in your engine, despite that it is turbocharged and pushing quite a lot of boost (and I'm assuming you take advantage of all of it, otherwise you wouldn't have chipped it.

).

If you get the oil analyzed in the future, try to have them test the TBN as well, just out of curiousity and to predict how much longer you could have safely gone on this oil.

Also, as someone else mentioned, it would be interesting to see how the M1 0w-40 would fare in these conditions, but from the UOAs I've seen, it gives very similar results in these 1.8T engines.

Oh, and
