Vehicle: 2005 Buick LaCrosse CXL
Engine: Buick 3800 Series III V6
Miles on Engine: 165,090
Miles on Oil: 4118
Oil Type: Pennzoil Platinum High Mileage 10w30.
Ran 10w30 for the summer months. Viscosity was a little higher than the 5w30s that I have been using,
although as Blackstone notes, it was a little below 10w30 spec.
Otherwise an unremarkable report, good news for an 18-year-old engine!
Current fill for the winter is Quaker State High Mileage Full Synthetic 5w30.
