Oil Analysis

[spikesputnik]

See below where Txab bailed me out and cleaned up my report.

 

These are my last analysis. The 3600 miles was on Penzoil 5w-30 dino and was the second oil change ( first was at 3000, second at 6400)

The reason I did these is that the oil looked "crappy" both times. I switched to M1 @ 10 K miles and changed with OLM saying 50% @5000 mi.

Thoughts?

Thanks txab!

Here a couple of reports to compare, from vehicles in our fleet

You cant change anything that you get in PDF form unless you have the password that was assigned to that document when they made it. That is why companies send everything in PDF, for security.

I guess my concern is what Balckstone is pointing out- the high copper and lead.

 

Other than Txab, are there other fleet managers or individuals that have had analysis done and seen these type values or worse that were or were not pointing to a problem realized down the road?? Or are these numbers really not high enough to be a concern??

 

My only personal comparison analysis are from a 57 hp diesel tractor with 500 hrs and a mid-service interval 13,000RPM dirt bike, both with very good/normal numbers, both of which are used and abused WAY WAY WAY beyond what this daily driver truck experiences.

 

Does GM needs to take an engine design lesson from Kubota or KTM?

There are tons of UOAs to review here...

Thanks Don- I'll be posting there soon.

Oil forums/discussions are soooo "interesting". Oil is a religion all to itself, and most of it/them comes from middle east.....coincidence???

How are you driving this truck? Drive it hard, pulling loads? Do you make a lot of short trips where you are starting and stopping the engine? BTW, I'm not a fleet manager. I just try to keep an eye on the vehicles I get to use.

 

You are taking the oil sample properly aren't you? According to how Blackstone describes it on their website?

[spikesputnik]

Txab- I dirve it conservatively 99.9%+ of the time, with the occasional road rage, stomp the gas 4500 rpm pass.

Not many short/unwarmed up trips, mostly 30 minute commutes, no towing, some lunch time idling 10 minutes, weekly 80 mph feeeway trips of 1-3hrs with <500# of cargo.

A warmed up, mid stream catch for sampling.

Before retireing I was a Owner Operator of 3 trucks. 98 T800 K.W., 2001 Volvo VT, 2000, Pete 379. It has always ben a recomendation from oil suppliers to change oil based on the oil annalysis, not on miles. This can be a pain, setting up a annalysis schedule for each truck, taking the sample, sending it in, then awaiting for the results to do your service, not to mention the cost for each annalysis. It was far easier to change the oil every 10,000 miles.........In my opinion it was just someone else trying to make a buck....

For the most part I have to agree, if nothing is wrong with the engine, there is really no reason for getting the oil annalysis. maybe get one at 10,000 miles, 25K, 50k, 75k, 100k(miles on truck not oil), just to make sure everything is good if your worried but every oil change is a bit overkill.
