Lab suggested checking for high idling, clogged air filter, improper fuel ratio.
Mechanic did indeed change filters and said they were nasty. I would say given the conditions this oil held up very well.

Where to H___ did the magnesium come from?

 

[D-Roc]

Pretty good for 35k...but probably time for a change. I would if it was mine.

 

[salesrep]

The guy had 70k on the uoa form, but his mechanic said 35k.
Yes he has change.

Has there ever been a "bad" Schaeffers uoa?

Ha. No I don't think there has been. It's such a good oil. I never hear a bad thing about Schaeffer's. Their PDS are the best by far.

 

[allan5oh]

lead seems a little high, what was the TBN?

Other then that, looks fantastic!

Schaeffers is a great oil - don't get me wrong - I just think when it's widely enough used in all kinds of beatmobiles - then people point at the oil (rightly or wrongly) as the cause for wear metals, etc.....in other words, give it some time. Right now mostly BITOG anal types with clean engines are using it and skewing the very small population size. Also most UOA's on Schaeffers are posted by salesrep.

Some of the posted uoa's on Schaffers have been long and high miles. The uoa on the semi was most impressive .I have never used the oil but I have been most impressed.

 

[allan5oh]

I'd say the high soot contributed to the high lead. Absolutely.

My miles are about the same, I had .1 soot and my wear metals were a fraction of what we see here, other then copper(13 ppm iron, 1.5 ppm aluminum, .7 ppmlead, 28 ppm copper)

I'm no expert by any means, but I'd really suggest this individual cut down their intervals. Get a bypass filter. Is this an EGR engine? If not, they have injector problems. ----, even if it is an EGR engine, I'd get the injectors checked. That's some crazy soot levels.

What part are you puzzled about?

 

[dnewton3]

From the past 2 years I've spent skulking around here, almost to the man/woman, we're all "mostly BITOG anal types with clean engines". With that in mind, I don't know that Schaeffer's products are skewed in UOA's any more than the guys I've read about running Amsoil premium synthetics with bypass systems and changing oil at 5K oci's ...

Most of us are on this site because we're just a little off center when it comes to all things mechanical. It's our passion; it's our hobby; for some, it's our livelyhood.

This Schaeffers UOA looks high in Fe and soot to me, but then on the other hand it does have 35k miles on it. That's WAY over the BITOG anal retentive self-imposed I-can't-help-myself-I-gotta-change-it limit.

very well said

grain field chaff and dust are killers of even the best air filters.

low speed summer field heat takes the best of oils
wouldn't be surprised if there is not some ring lock in this engine.

is the "mechanic" dosing the engine with oil additives, mag.?

particle count needed to see if air filter is contaminating oil and oil filter.
this engine begs for a real mechanic and TLC
new trucks and engines are not cheap
