The first column is the most recent one.
The oldest sample was with some petro canada 5w30
The other "N0000" is Canadian tire oil
latest Pennzoil dino 5w 30

With pennzoil more alum. lead,and more viscosity lost , more a 20 than a 30 , am i right to be disapointed by Pennzoil ??

sodium , potassium, boron , lower intake leaking again ???

Lead, iron, aluminum, sodium, and potassium rose. Maybe you're showing some glycol seepage into the sump too dilute to catch in the UOA yet. (I'm no expert.) On the other hand, short trips in cold weather (Gets cold in Canada, eh?

), a little fuel dilution, and salted roads could be the culprits, too. I wouldn't say you're in imminent danger, but these results do bear watching for comparison with your next UOA.
 
I'm not sure you have another intake leak. Did you have on fixed? When? Might want to let Terry look at this bc of the lead and tin. But personally, I'd give it another run or two before hitting the panic button. Na and K are pretty low. If its a leak it is very very tiny.

IIRC they replaced the lower intake manifold gasket at around 40000 km or 25000 miles

I'll follow your suggestion and wait for the next UOA, so in late fall or around 7/8 thousand km

Thanks for your input guys
