That's one anecdote though.Here is your question, I like Motorking’s answer.
Can too thick of oil be damaging?
Simply put. If an engine calls for 5w-30 and you run 20w-50 instead, aside from power loss and hydrodynamic friction, can damage to the bearings, hydraulic lifters, chain, rocker fulcrums, etc... occur from an oil being too viscous for the application? This includes long term wear.bobistheoilguy.com
