Figured that it is only money, so I picked up some Amsoil XL 5w30 for the expedition.

I've used about everything else and I always get high metals, so I figured there is no harm trying something else.

I'm expecting great things ....












Ok, not really.

But I can compare amsoil to castrol edge, Napa synthetic, Mobil 1 HM.

Honestly, the only reason I haven't tried it earlier is cost. But I now get the preferred customer pricing so I got it for $25.xx per gallon, which ain't bad. Still %25 more than WalMart prices, though, which has always been the deal breaker for me.

So.... I drank the cool aid ....

Aluminum and iron. Both are far higher than normal and have been since I bought the truck.

Clearly there is better oil at Walmart than Amsoil XL oil.


Perhaps, but I'm only going 7,500 miles. Their top line oil would have been wasted on such a short interval. As too would have anything "better" at WalMart.

If nothing else it will offer another data point.
 
Went and looked at Amsoil site - the 10w30 XL looks interesting with a 3.3 HTHS & real low NOACK ...

If you always get high metals, then it sounds like your trend is flat, which, for UOA, is more important than actual values, for the most part.

I dont know about flat ....
Aside from the one outlier, they are just "not stellar"

I'll have another one to post here in a few weeks.

It looks like the Phillips product produced the best numbers, and I wonder if the metal is indicative of upper cylinder wear. No copper so bearings aren't suspect, perhaps too the higher iron and aluminum is indicative of good cleaning? I'm still new to reading UOA's, but its my understanding that constant brand change/formula differences keep trends from establishing, and also can lead to good cleaning

That's true in the respect that his engine is not getting any worse. But there are documented cases of some oils in some engines producing more metal.

Welcome to the club! I'll be interested to see the UOA once it comes out. If the Amsoil doesn't make a difference it looks like you should go back to the Trop Artic!
