Engine/Transmission (1998.5 - 2002) High Molybdenum Count in Oil Analysis

[PRout]

Just got my extended oil analysis (more like abused oil w/ about 30k miles on it) back from Blackstone Labs. It looks better than expected with low numbers across the board. They recommended go another 5k miles and change it.



Except: Moly count is 70ppm!



The question is, does this look like an oil additive, or should I be concerned about abnormal wear on a piston ring?



Oil used was about half Delo & half Amsoil mixed.



I'm thinking its an additive, but definitely going to watch it in the future.



Thanks.

Shortshift,



Moly? That's that Delo!



Half Delo and half Amsoil! Sweet! I was going to do the same thing! What do your wear metals look like?

Gonna keep a close eye on this one!

As far as I'm concerned, Moly and Boron are the 2 best things Chevron Delo recently started including in their Delo 400 for improved wear reduction - be HAPPY it's in there!

I'm with Gary!



Lovin' the additive package of Delo 400!



Hey Gary, can you point me in the direction of "The Great Amsoil War" here on the TDR? Sounds like good readin'!

 

[PRout]

Great! I'm HAPPY it's in there!



Will try to post the numbers tonight. . Yeah, kind of got into a pattern of changing the oil using Amsoil, then using Delo as make up oil when changing TP filters. Am not a chemist, but like the extreme temperature handling abilities of the syn (mostly for times of hot shutdowns), combined with the seal expander qualities of the dino (concerned about leaks using straight syn). Seems to make sense anyways...



Oh no, not more "Oil Wars"! hehe

Stick around - the latest version of the "Amsoil war" will no doubt be resurfacing here in THIS thread very soon... :-laf :-laf

Lord I hope not.



That would make TWO superthreads I would have to read!

Sample taken at around 28,000+ miles. Used about 4-5 qts of Delo as make-up oil. Using 2 frantz filters in series with about 1 pint per minute flow rate. The frantz filters were not changed for about the first 15k miles, and the oil looked very dirty (black soot). Started a clean-up experiment and started replacing TP elements at about 2k intervals recently. Oil "looks" somewhat cleaner, but is still dark. Sample was taken at this point. Will probably give it another 5k and see what happens.

 

[Gary - K7GLD]

Shortshift - your sample looks VERY similar to my 20K run with Delo 400. Your copper looks higher than I remember mine being - but a very nice analysis!

 

[PRout]

Thanks Gary. . Yeah, looks like the oil cooler may be releasing a little copper into the system (hopefully). Thank goodness for Scotts 1000 sheet rolls!

 

[Gary - K7GLD]

I dug up the pic of my 20K analysis for comparison - my engine was still pretty low mileage when that was started, might have allowed slightly more Iron than one with a few more miles, but still not bad:

[PRout]

Very cool. . Here are the comparisons. . I guess this is what a person could expect if they are running a Frantz and have 20-30k miles on their oil.

I might mention that the whole distance in my test was with the earlier no Moly Delo 400 oil - only the last 2 TP cartridge replacements were where I used a quart of the newer Delo with Moly for makeup oil - that's why my Moly and Boron check lower in content.

 

[ThrottleJockey]

A VOA of Delo 400 for comparison

While it has absolutely no bearing on this thread... I am switching back to DELO from Amsoil!!!



Reason being... . fuel prices have made me look at the budget, and when you can buy 3 gallons of DELO for the same price as 1 gallon of AMSOIL HDD Marine..... the decision is easy!!!



Oh, I do not run an extended drain interval... not a good idea on a BOMBED truck IMO.
