Can you "feel" a difference after a regular oil change?

So long as you have satisfied yourself you are correct that is the end of the matter no matter how wrong you happen to be.

As an aside, take a glass of water and add a teaspoon full of sand to it. Shaker it. Does viscosity change? No? I wonder why given you believe entrained matter changes viscosity. Incidentally viscosity and lubricity are two separate characteristics.

Combustion products in engine oil are entrained matter although some oxidation does occur which does not adversely affect lubricity or viscosity. What does get depleted in engine oil are additives which are the principal reason for oil change.

On the matter of combustion products, provided the diameter of the products do not exceed oil film thickness they will do no harm and will be removed by the filter. Combustion products in the oil of a well maintained gas engine are minimal as compared to a trunk piston diesel engine.

wow, i love this guy! facts simply don't get in your way, do they! what's next, mud is the same viscosity as water? 'cos that's the way /your/ example works buddy.

you need to go back to your old high school and have a word with your old science teachers - they failed you big time.

What is a trunk piston diesel engine?

Is that a diesel engine in a rear-engine or mid-engine car?

Perhaps he meant "truck diesel engine."

I've googled for it, it just means normal pistons as in any i.c. engine instead of a thin piston driving a piston rod to a crosshead as in steam engines.
