Oil/Fuel Dilution Concerns...

In these engines, the oil pressure starts to build as soon as the starter turns the flywheel, or motor/generator turns the crank. The ECU won’t allow the engine to fire up until minimum oil pressure parameters are met first. The oil pump is primed and the oil system is at minimum pressure to start before the engine is allowed to start.

Gotcha, this makes sense to me, thank your for explaining this.

Oil pressure is relatively instantaneous

Watch the oil pressure gauge in the instrument display. As soon as it is visible it is already at full pressure - instantaneous as @JayZap said.

Between oil changes, does your engine oil and level:

Non-Hybrid: Remains at the full mark

Hybrid MAX: Remains at the full mark

Non-Hybrid: Oil level increases over time

Hybrid MAX: Oil level increases over time

Non-Hybrid: Fuel smell on dipstick/oil

Hybrid MAX: Fuel smell on dispstick/oil

Non-Hybrid: NO fuel smell on dispstick/oil

Hybdrid MAX: NO fuel smell on dipstick/oil
