Looks good but I am curious about one thing. This same oil in my Ranger had great results but a much weaker add pack, I wonder why? Comparitively; My Ca was 1500, P was 400 something and Z was in the 600's. As I said though, great wear numbers.

Do you do a UOA on every OCI? I'm continually impressed by the UOA's of this fleet.

Amazing. I'd like to know the TBN

Two years old with 97,000 miles. How long does it take to rack up 10,000 miles?

If you are getting it done at blackstone, they consistently report low add numbers.

Surprisingly this was done by Schaeffer's.

Your guess is as good as mine, then.

I can't speak to the difference in additive numbers between your samples and these unless you used the Schaeffer's kits from Wearcheck, with the TBN? This was a Schaeffer's in house kit.

I don't sample every oc, but usually at least every other.

I stopped testing for TBN after a time when it was clear the TBN retention would hold to 10k+ in our type of service. I shoot for a 7500 mile interval knowing 10k+ is no problem. That way if they don't get serviced "on time" there is plenty of cushion.

Based on our past Polaris reports with TBN I would guess in the 2.5-3.0 range.

I will have to check to be sure, but I think this is about right.

This report should be enough proof that 5w20 works just fine in the CVPI.

 

[Nick R]

Yeah I'd like the thinophones explain away this one.

I have complete faith in 5W-20 to protect these engines. This unit overheated severely a while back when the alternator pulley took out the serpentine belt. Still runs like a top and it never caused any change or spikes in metals. We have another unit that has severely overheated a few times as well when the cooling fan died-it's been fine as well. Surely a good bit of credit goes to Ford engine protect in those situations as well.

When it comes up for review: "Well, that one doesn't count".

Yep-2.5 months, almost to the day.

 

[panthermike]

Interesting, the lab was in house Schaeffer's? Oh well, not worried about it.

Thanks REDDOG for the interesting post.
