Diesel engines generate more soot than gasoline engines, so its important to choose an oil that contains detergents that help keep soot particles suspended in the oil and prevent them from building up on engine components. Look for an oil that meets ACEA E6/E7 requirements for strong detergent protection against soot deposits.

4. Additives

The base stock of an oil is only part of what makes it effective additives can also play a big role in its performance. Look for an oil with additives like zinc dialkyldithiophosphate (ZDDP) or molybdenum disulfide (MoS2) which can help protect against wear and tear on engine components, as well as corrosion inhibitors that reduce rust and corrosion inside the engine.

5. Price

Price is always a factor when choosing an engine oil, but it shouldnt be the only consideration make sure you get an oil with all the features you need at a price you can afford. Its also worth noting that synthetic oils generally cost more than mineral oils, but they can provide better performance in extreme temperatures and may be worth the extra expense depending on your needs.
