Reducing Subsidy: Is It Harmful?

I wanted to reduce the flow rate, but isn't it more harmful if it's too low?
I somehow feel that a little bit of something is better than nothing, don't you think?

You have a diesel engine that's always running too lean... if it were running properly, you wouldn't be able to see anything behind your car because of the smoke.

For a gasoline engine, it's better for it to run slightly rich rather than lean, as this helps prevent overheating.

With a diesel engine, you just get less power.

It's generally more harmful if the amount of fertilizer is too high than if it's too low.

After a certain amount, yes, but before that, the dark street behind you will already bother you...
