The oil may not be an xw-5 to begin with, I don't think the grade officially exists.

That being said, oxidation thickens an oil.

Do you know what the virgin specs are of this oil? Like previous posters have said, based on the 100C viscosity, this is an xW-20 oil.

Also, I can't find it listed on Neo's web site.

So the lead is high but to be expected with such a thin oil and how you drive it. How much longer do we think it will last before the bearings have finally had it?


Lead is less than 1ppm per 1K miles so the bearing should last me another 300K miles at least.

What other mods have you done? How much of the mpg improvement do you attribute to oil viscosity?


You can see some of the mods in the engine pic. OMI intake, EGR deletion, DG race pipe, PCV vent to atmosphere, 3" straight exhaust, Aiken fuel box, advance injection timing, 205/70-15 tires, 2T fuel mix, and low viscosity oils. The low oil viscosity is good for 3-5mpg.

The Amsoil bypass filter took care of the soot and allows me to run non diesel oil.

What BITOG users assumed, misread, misunderstood, etc. are not my problems. I will always used the correct terms as defined by the process.

Maybe in the future just state "6 quarts intial fill and two quarts makeup". wink
What are you oil pressures wtih this viscoity? I asked this question once before.

Engine ran fine in Arizona heat with no problem even when it was overheated. As long as I don't get a warning from the ECU I don't really care. I might thin it out even more with ZMAX in the near future.

Well since you don't care about the pressure, I will not either.
IMO, and I'm certainly not an expert, those are pretty high numbers considering you running a bypass system. I sincerly wish you luck though getting another 300k out of this engine.

Based on the VOA/UOA #s, we know this oil didn't begin as an XW-5 - it's definitely on the thicker side of an XW-20.

The higher UOA KV @ 100C could be the result of oxidative thickening; however, the oxidation between virgin and used is very low, so another explanation could simply be inconsistencies between each bottle of oil. IN OTHER WORDS, the bottle of oil that the virgin sample was drawn from might have been thinner than than the average of all the bottles of oil added throughout this OCI. Just a thought.

Also, you're spending a lot of money on this oil - doesn't need any help (RE: ZMAX.) IMO, buy an oil suitable for the task at hand and let it do its job, by itself - no need for additives that may not play well with the oil's chemistry.

I ask this once. Does this oil have the CL rating? If not what diesel rating does it have? Thanks.

Why do you even read this thread if this is what you believe in?

Why do I run 0w5 when practically any 5w40 will do? You just don't get it.

Could you please explain what it is that I don't get? You've said that a couple of times thus far, but it makes less sense each time you type it, since you never explain your logic.

I'll say again that YOU'RE NOT RUNNING A 0W-5 OIL - your oil is an XW-20. Furthermore, no where did I say that you should run a thicker oil, either, so apparently you don't get it. It's ok if you don't understand something, but being combative to those on this forum trying help you is counter-productive. So, to answer your question: I'm reading and responding in this thread in reply to others mostly, not you, since you don't seem receptive to any advice or feedback.

Finally, I was simply giving you my opinion that a good, stout oil does not need the help of any additive, and that not only can some additives be a waste of money, but they can hamper the additive package of the high-dollar oil you're using. What's not to get?

Those specs are worth less than the label they're printed on, broseph.

That's awesome. I admire you going a couple grades thinner and using your own vehicle as the test mule.
Do you know what the averages are with this engine using the vw spec grade oil. I doubt they could be all that much better?

Over in the TDI Club forum they have a thread listing UOAs. Many are worst than mine and at 10K miles or less.
