00:00 Gasoline Tiers
01:26 Diesel

BeamLR 1.14.2 update comes with a new improved fuel system which adds different Gasoline tiers as well as Diesel.

Gasoline tiers are Regular, Mid-Grade and Premium. Using better gasoline tiers gives a slight increase to output torque, this is not 100% realistic (from what I understand in real life high octane fuel is used in high compression engines to prevent knock which means it must be used to achieve full performance) but makes sense for gameplay in a racing game. The fuel quality and output torque increase is calculated by checking the ratio of different fuel tiers in the fuel tank. For example, a gas tank that contains 100% Mid-Grade fuel has a fuel quality of 110%, with Premium fuel it would be 120%. Any different mix is calculated accordingly, for example 50/50 Regular and Mid-Grade would have a fuel quality of 105%. This value is used to scale the engine's output torque.

With the addition of Diesel, checks are now performed when refueling. When the incorrect fuel type is used (For example Diesel in a Gasoline engine), the engine will be disabled and can only be fixed by first draining the tank before adding the correct fuel type.

For the first release of this feature price scaling between fuel types and tiers is hardcoded however future versions may add map-based fuel price scaling since I believe Diesel is cheaper in Europe than in the US.
