Who’s doing what now?

You’re driving at 32 mph
Automatic transmission usually ‘shifts’ at 35
fuel/engine life is it better to drive fast enough to ‘shift’ or stay at 32?

I was told there would be no math

Let Me Google That

For all those people that find it more convenient to bother you with their question than to google it for themselves.

Yeah... after you get past the 4-5 ads that tell you things like "Low foot fungus prices on EBay!"... then you get the blogs that say things like "What the CDC doesn't want you to know! Soak your foot on Drano, and wrap your foot in tin foil!"

This is an old car question. New cars have enough gears and enough controller processing power to render this a non-issue. What car, specifically, are you asking about? Is there a grade? Wind? What altitude are we at?

It was actually more of a question when I had a Kia forte
Now vw Jetta is much smoother and rpm don’t change much whatever I do

Your question is roughly analogous to, "What shoes for dancing?" with no additional context.
Both a grade, or a significant wind change the answer to your question, but in general, less fatigue, but lower mileage in the lower gear, but better mileage with more fatigue in the higher.
