Right.

Because the higher the gearing, the more load is placed on the engine going up that grade, because the gearbox is leverage.

It's mechanical advantage.

So then you have the oil temperatures.

So with the oil temperature, the main thing that plays into oil temperatures is ambient temperatures, because ultimately with me, I don't see a big difference in CHTs, in head temperatures, on a 70-degree day versus a 90-degree day.

I don't really see it.

The oil temperatures, absolutely.

Yeah.
