Will diesel oil damage rings and seals on a petrol motor?

Diesel oil is not recommended for use in petrol engines because it can cause damage to the rings and seals. Diesel oil has a higher viscosity than petrol, which means it flows more slowly and does not provide adequate lubrication for the engine's moving parts. This can lead to increased wear and tear on the rings and seals, which can eventually cause them to fail. Additionally, diesel oil contains higher levels of sulfur than petrol, which can corrode the engine's internal components. For these reasons, it is important to use only petrol in a petrol engine and to avoid using diesel oil.
