Red Line 5W-40 VW TDI (ALH) 10K samples

[hannaco]

This was meant to be posted a while back. The reports were found the other day hidden under a bunch of stuff.
Total miles on each sample was 10,000 miles.

This is going to be UGLY no matter what I do. without the separator dots, it is very hard to read, with the dots it is just hard to read. What ever happened to the "code" option for entering tables?

Samples taken at 200k, 210k, and 220k miles on the motor.

Great numbers. I've always been impressed with RL 5w-40's shear stability. Tbn is strong considering 10k miles are on the oil!

Very respectable reports.
What is up with the B?

 

[Steve S]

TBN is up there.

"What is up with the B? "

This is the "new" formula oil. Maybe they have a new additive?
Looking back about 60k miles, the values changed from single digit to double digit values for Boron when they went from the Red bottle to the Blue bottle. It could just be a new Boron ester that they are using.

Regardless, the motor is happy.

Iron seems like it is growing on you.

 

[hannaco]

OEM oil filter has been used from the begining.

Yes, Iron varies a bit. Still on a per 1000 mile basis, not all that bad. In this motor it has always been a bit on the high side. You can look up what it was using Delvac-1. It was in the tripple digits until the switch to Red Line.

This one of your D1 tests:

Shows iron as 39?

 

[hannaco]

Yes, now go back four oil changes more. If I remember correctly, Terry got involved in the prior drain cycle to clean up the high Iron content. The next change was to the Red Line oil at his suggestion. Stayed there ever since.

So what was the cause of the higher iron if Terry was able to clean it up?
