Can I Put Diesel Engine Oil in a Petrol Car? A Comprehensive Guide

Diesel engine oil and petrol engine oil are two different types of lubricants that are not interchangeable. Diesel engine oil is designed to lubricate the high-pressure, high-temperature environment of a diesel engine, while petrol engine oil is designed for the lower-pressure, lower-temperature environment of a petrol engine.
