My oil analysis with Amsoil This is using Amsoil ASL 5w/30, with the amsoil ea oil filter, and a magnetic drain plug. I used this oil for 10000 miles on this sample, the engine is at 30000 miles when I took the sample. I only had to add a quart of oil in the 10000 miles.I went with www.blackstone-labs.com to try them out for the analysis. This is what they said
The oil companies that say you can run the oil a long time don't usally mention the fact that the oil collects metal as you use it, and that metal makes oil abrasive. Then it's not able to do it's job (cleaning, cooling, lubricating parts) as well. So the question is, how much metal is too much? When metals reach twice the universal averages, that's the point where we'll say it's time to change it. Whether you agree or not is up to you. Iron, Copper, and lead are from the bearings. No other problems turned up. We may also be seeing lingering wear in.
Sample Universal Average
ALUMINUM........4...............3
CHROMIUM.......2...............1
IRON...............40............20
COPPER...........60.............33
LEAD...............14..............9
TIN..................1...............1
MOLYBDENUM...71.............67
NICKEL............3................1
MANGANESE.....0................2
SILVER............0................0
TITANIUM........0................0
POTASSIUM.....4................2
BORON...........56..............53
SILICON.........19..............13
SODIUM.........21...............13
CALCIUM........3181..........2207
MAGNESIUM...12...............144
PHOSPHORUS..648............686
ZINC..............825............839
BARIUM..........0.................0
Sample Universal Average
WATER %.....................0.0................<0.1
ANTIFREEZE %................0.................0.0
FUEL %.......................<.05...............<2.0
FLASHPOINT INºF...........375.............>365
SUS VISCOSITY@210ºF: 59.7.............56-63
cSt Viscosity @ 100°C: 10.14...........9.1-11.3
INSOLUBLES %..............0.2.................<0.6
So the question is, is this common with the lsx family of motors to have high Iron, copper and lead?
