What Will Ruin A Diesel Engine?

Poor maintenance, low-quality fuel, and neglecting oil changes can ruin a diesel engine over time. Ignoring warning lights, overheating, and using the wrong engine oil also lead to serious damage. Regular inspections and timely repairs help extend the life of the engine and avoid costly breakdowns.

Do Diesel Engines Need To Warm Up?

Yes, diesel engines need a short warm-up period, especially in cold weather. Letting the engine idle for a couple of minutes helps oil circulate and parts reach optimal operating temperature. However, excessive idling can cause carbon buildup and waste fuel, so keep warm-ups brief.
