Hi,

Highway driving will not prove anything but does clean the cylinders. Sometimes referred to as an “Italian tuneup.” It’s probably why the accelerator pedal is more long and narrow than the other pedals to match the early styling of narrowly pointed shoes. 🤓

A cylinders oil rings give up more oil with around town driving or quickly letting off the accelerator at high speeds.
The closing off the intake manifold instantly or regularly raises the vacuum level higher and when the intake valves opens it get that vacuum applied.
With the crankcase already pulsing from the other cylinders movements and blow by the scenario is set for oil to go past the rings.
This happens to some extent no matter the miles or age of the engine.

I suggest use the car more in a fashion of slower around twin driving that the wife probably does or put in a little hotter heat range plug. Only go up one step in heat range though.

Phil
