Now I heard from you that the normal 10-40 hyr produces special oil for LPG,

The service here was using the brand Valvoline. I saw it in races, but in real life I saw neither on the shelf nor in the car

Lubricating oils produced for LPG is the same oil choice that only writes for LPG on the label of the oil ....

25 lira was very convenient for me and castrol
