But, how do you know that other oils wouldn't hold up equally as well? Possibly you like the product and that is fine, we all have our favorites. But lets remember what is important here, and that is protecting your investment.
For me, I don't know about anyone else, but if I had
Iron 92
Aluminum 19
Lead 26
Copper 21
Silicon 41
In MY (no one else's truck, hypothetically speaking here) 2005 Ford F350, I would be waiting for someone to tell me to pay a little closer attention to my maintenance schedule. I flat out think the interval is too long, and if it was my truck would be alarmed at the numbers, as well as my inattention to detail, as well the oil analysis company telling me that the sample was "normal", or "no corrective action required" having someone in a lab tell you what is happening and looking at it from a first hand point of view are two different things.
But yes, I guess I can take a positive from it in that the engine is at least still in good working order after 22 549 (or was it 31 703 miles?) on that oil change. I would not expect the engine to last a long and happy life with consistent oil changes at those intervals. :2cents:
if you look the unit has a total of 31,703 miles.
we were happy with the results.
nothing was flagged except for the silicone wich should be from a new engine.
we did change it after 22,000 miles, I think it was time.
we will sample the same truck with the same blend oil in another 6 months.
now the truck owner is happy that his truck gets 28mpg rather than his friend with the same vehicle getting 15 mpg.
the aluminum,lead, copper and silicone are not abnormal and if you look carefully on the oil analyzers guide the metal wear numbers to compare with are for conventional oil.
I looked at the wear metal guide...guess my version of acceptable and OA's view are totally different, I know Blackstone's view is different yet again. But, I'm pretty fussy with my rig. For the owner, if he plans on keeping his truck and using Amsoil, perhaps an Amsoil bypass and AME 15W40 might be in his best interest...
