Oil Analyzers Inc is the main company that Amsoil uses and recommends for oil analysis. They do sub their samples out to a few other labs, including Cleveland Technical Center (ctc). I have used them since 2001 for many samples and they do a good job. I'll tell ya one thing, unless you pay more than the average test, CAT testing is pretty poor in my opinion. They don't even include TBN. Blackstone labs are good as mentioned above, as is the lab that AVlube uses(
www.avlube.com) which is called Predictive Maintenance Services. PMS and CTC also do fuel analysis testing!
Rotts/Don - nobody has suggested this yet which surprises me, but I think that a good contributor to your high wear metals - is the fact that your truck is still breaking in. The high silicon reading would confirm it. Most oil analysis experts will tell you not to even bother testing until you have 20k on the clock of normal vehicles - plus we all know how long it takes for our trucks to break in. When/how many oil drains have you done before this 13-18k run?
Does the truck appear to be running well and getting normal mpg's?
It's clear that changing the oil sooner will not help, because the oil is still in new condition. The TBN is still extremely high, and oil is typically 'shot' when the TBN reaches 50% of its original number (provided other factors don't meet the threshold, like soot, metals etc).
I wouldn't waste time sending in new samples or messing with it further, provided the truck is running well. If I were you, I'd dump the current oil out, get yourself a stratapore filter, and check 5000 miles from now again. I don't think the Fram filter would have singlehandedly caused these high wear metals, but as mentioned above, they are less than desireable if you've got a choice in filters. In a pinch, the napa branded filters are made by fleetguard, however they are the normal version, not the stratapore.
