My 84 305 does the same thing. 10w30 mobile1 and mechanical gauge. Just changed the oil and filter. Once warm it's down to 5 to 10 range at idle but up to 20 to 30 on the highway. I figured as long as it goes up with rpm increase I'm good.
Same oil in the 454 but it seems to stay around 20 to 30 at idle warm. And over 40 on the highway. So I don't know if I need to be concerned about it or not.
