Can I use diesel engine oil in a petrol engine, and vice versa ?
Petrol and diesel engines have different lubrication requirements. During development, lubricants undergo a number of tests, some common to diesel and petrol engines and others specific to one or the other type, that categorize their performances. At the end of this process, they are awarded an API or ACEA/CCMC compliance standard. These specifications characterize the acceptable functioning of the lubricant in each type of petrol or diesel engine. Lubricants for four-stroke engines usually comply with both petrol and diesel specifications. For example, an API SJ/CF lubricant meets petrol specification SJ and diesel specification CF. But this does not necessarily mean that it will perform in the same way in both petrol and diesel engines. This is why Elf has developed specialized ranges, optimized either for petrol or for diesel.
