Can anyone help me to decipher this? I have compared this analysis to others I have found on this and other forums but just wanted to confirm everything is OK.

It looks normal. The zinc and phosphorus are in a typical anti-scuff additive (zinc dithiophosphate). Calcium compounds are a major detergent-dispersant constituent.

Iron is from the block; aluminum from the pistons; copper, tin, and lead from the bearings.

Silicon levels are normal - overly high amounts indicate a leak in the intake or a bad filter.

Important is that there is no glycol (coolant), as that's one thing that can trash engine oil in a hurry.

Viscosity at 100
