What is the "VW" Longlife III oil you ran on your most recent changes? [Edit: You must mean the dealer Castrol 504/507...]


Impressive Fe numbers. Are you only going to run a 6k max OCI, or will you adjust with these numbers showing all's well?

Not sure what to do with the DRF info - what are "good" numbers (though I presume what you've got there is at least "very good"!!)?

The oil is slightly different than Castrol Powerflow SLX III.

Its bottled for VW part # G052195M2

VW LongLife III. If you order it from Impex you will get the new bottles not the VW bottles.

I ran the oil to 7000 miles and I will test the next OC at 160 hours apx 6500 miles. I may switch to Total 504/507 as I am close to finding a local supplier.

The DRF is good at 2.5 to 1 the explanation is at the club in my UOA thread - link in sig

Looking like the Castrol 504/507 might have a little AL in it's additive package as well huh?

Your AL rose slightly.

I did a VOA of this oil and it has a Al count of 3 - this is a good UOA for Castrol. The next UOA for this engine same oil will be at 7k. I am trying to buy Total Quartz Ineo 504/507 for the next fill. I will test it at 8k since these oils are virtually identical.

Thanks for sharing. What are your thoughts on the ferrography?

buster,

Here's an article on UOA measurements taken with RDE (rotating disk electrode or Rotrode) analysis and Direct Read Ferrography.

Because of the larger particle detection size of Rotrode, the correlation and trending is pretty good between the two.

Thanks, good article.

What are the Chromium and Nickel from?

 

[wjdell]

Cr - Ni would be valves, rings and bearings - those are normal for a VW TDI.

Your oil looks good as usual. From what I have read the Elf/Total 507 has slightly better additive package than the VAG/Castrol 507. As you know I will have a UOA for this soon. I have 10,500 miles on this UOA. This is my first batch of 507. I am anxious to see what the 2nd batch will look like, especially since I got my failing EGR fixed (er... cough blocked off).
