sorry.......... i was mostly asleep when i got home last night and went looking for this thread for the OA place in calgary and posted my previous question before i saw the other thread on fuel filter setups haha

 

I just did a nother test and it's all good still Changed the filter and topped up at the last report, @ 25,000kms now up to 35,000kms and still good.

 

My 6.7 can't generally get past 8-10,000 kilometres before the TBN is down below two. Soon H&S is going to help me remove the egr and dpf so things will run much cleaner.

About your TBN, I am confused if it is still up at nine, how can you have any acid in the oil? The TBN is indicative of the additive that neutralizes acid and depending on what Amsoil oil you put in, it starts out at ~12.

Honestly, if your oil has 24,000kms on it for real, these results are fantastic. The only thing I might do for ***** and giggles it to change out the filter at about 1/2 of that mileage...just to be sure it doesn't ever plug and go on bypass. You would never know that has happened until the next analysis and by then, the damage is done.

The number you are looking at is the new oil number in the far right column.It is 5w-40 amsoil and it actually has 35,000 km's on it at the last sample.I have changed the filter twice and i plan on doing it at 15,000km intervals.

 

Those results are just beautiful. Nice results for a non stationary engine that sees all kinds of temps and running conditions.

 

Yeah i'm pretty impressed to J, gonna runn'er until they say not too.

 

Thanks for the reminder Chris....I still got to get my 15-40 Amsoil tested in my truck...

So far no oil leaks since the change over... I better check....maybe its burning it instead..

 

I just did another sample this week, came back with a big spike in copper, hope i don't have a bearing issue.

 

With that spike in Copper is also a modest increase in Ironand Silicon. Those usually indicate dirt ingestion coming to the engine like a leaking air filter or hose. There was also an increase in sodium which is sometimes a residual of coolant.

Also with those increased levels there is a slight increase in viscosity which goes with the contaminated oil and increased solids content. It may be time to do a change or at least check the filter. I don't recall if you are using a bypass oil filter or not.

If you are to the copper, your bearings would be toast by now. Without a huge increase in lead first, copper is usually from a bronze bushing, oil cooler or something of that nature.

I would resample fairly soon and if the levels are the same, change the oil.. IMHO..

 

Dam....I have to do mine also...

 

I'm not too worriedabout it now after reading this article that Herb sent me, i did a coolant swap in between samples.

Eat beef I get my baldwin fuel filter from a Peterbuilt truck shop that services Cummin`s they were $11.00 bucks a pop yesterday, better filtration than amsoil and way cheaper, and they drop right in, donaldson oil filters from Freightliner shop $7.50 a piece, they also sell fleetguard made by Cummin`s $8.50 a filter.

 

Thanks. I'm using the Baldwin drop in filter. I get them by the case at Acklands. I also rigged up the GDP aux. fuel filter kit. Easy! I think I have clean fuel now.

 

Which Donaldson filter? I'm guessing a P series & not the Endurance filter.

Still, very good prices.

 

I just had another sample done 61,000 km's on the same oil and still good to go.
