Is 10w30 good for diesel engine?

Mobil Delvac™ Extreme 10W-30 is a synthetic, high-performance diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions.

What happens if I put 10w30 instead of 15w40?

Don’t sacrifice wear protection for fuel economy.

Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.
