Hello, I am installing 5x server, there are multiple plugins available but today I found 9.000.000 poor low oil quality l. Can any plugin be posted or connected to this annoyance from the plugin?

I've gone through it, but helicopters' spawn time stores come with 9,000,000 fuel.

Helicopters purchased by vendors have 20% of max stack size of low grade fuel. If you are seeing more fuel than you expect, that is because you are using a plugin that alters stack sizes. Several plugins fix this by allowing you to specify a different fuel amount for purchased helis, such as Air Fuel or Vehicle Vendor Options.
