7 Driving Habits DESTROYING Your Ford Diesel Engine Without You Knowing

Think Your Ford Diesel is Bulletproof? Think Again

Introduction to Common Driving Habits

  • R.J. discusses the misconception that Ford diesel engines are invulnerable, citing personal experience with various models failing under 100,000 miles due to common driving habits.
  • He emphasizes that proper care can allow these engines to last up to half a million miles, but poor habits can significantly shorten their lifespan.

The Impact of Driving Habits on Diesel Engines

  • R.J. has over 20 years of experience working on Ford diesels and stresses that engine failures are often due to owner habits rather than mechanical faults.
  • He introduces seven harmful driving habits, noting that many owners unknowingly engage in them daily.

Habit #1: Cold Starting and Immediate Driving

  • Cold starts cause significant damage; starting the engine and immediately driving off prevents proper oil circulation.
  • Correct practice: Allow the engine to idle for 30-45 seconds before driving gently until temperatures normalize.

Habit #2: Excessive Idling

  • Long idling leads to low combustion temperatures, resulting in incomplete burns and soot buildup in critical components like the EGR valve and DPF.
  • Correct practice: Limit idling time; if necessary, use high idle mode or block heaters instead of prolonged idling.

Habit #3: Lugging the Engine

  • Lugging occurs when drivers operate at low RPM while towing heavy loads, leading to low oil pressure and increased wear on engine components.
  • Correct practice: Maintain RPM between 1800 to 2300 when towing; downshift before inclines for optimal performance.

Habit #4: Hot Shutdown After Heavy Load

  • Shutting off the engine immediately after heavy towing can severely damage turbos due to lack of oil circulation during high heat conditions.
  • Correct practice: Allow the turbo time to cool down by letting the engine run for a few minutes post-heavy load before shutting it off.

Turbo Lifespan and Cool Down Practices

  • Proper cool down is essential for turbo longevity; failing to let the engine idle after towing can lead to significant damage, as seen in a case with a 2016 F350 that required a $2,100 turbo replacement by 85,000 miles due to owner habits.
  • All diesel engines, including the 60, 64, and 67 models, require a cool down period of 2 to 4 minutes after heavy use to prevent turbo failure. This habit can double the lifespan of the turbo.

The Dangers of Short Trip Driving

  • Short trips are detrimental to modern diesel engines as they prevent reaching optimal operating temperatures necessary for proper combustion and regeneration cycles. This leads to several issues: cold turbos causing poor lubrication and soot buildup; insufficient combustion leading to heavy soot production; and overloaded DPF systems due to incomplete burn cycles.
  • A real-world example highlighted a 2020 F350 with only 22,000 miles suffering from multiple issues like clogged DPF and rough idling due to frequent short trips of just two minutes each. Corrective measures include taking longer highway drives weekly to allow full temperature reach and complete regens.

Bad Towing Techniques

  • Common mistakes while towing include using too high a gear (causing lugging), riding brakes downhill (overheating components), allowing transmission temps to spike without downshifting, flooring it while towing (leading to EGT spikes), and using cruise control on steep grades which can cause excessive strain on the engine.
  • A customer’s experience with an F250 illustrates how neglecting RPM management during towing led to extensive repairs needed at just 90,000 miles due to bad habits like staying in high gear at low RPMs under load. Correct practices involve maintaining RPM between 1,800 - 2,400 under load and monitoring EGT levels closely.

Turbo Management

  • Modern diesels have powerful turbos that are sensitive when abused; common causes of turbo failure include applying full boost before oil warms up or maintaining long periods of sustained boost which leads to wear over time. Proper care involves avoiding full throttle below certain RPM thresholds and ensuring clean air filters are maintained.
  • Drivers often underestimate their impact on turbo health; many believe they haven't done anything wrong despite evidence suggesting otherwise through their driving habits related to boost management and oil temperature considerations. Treating the turbo well can extend its life significantly beyond typical mileage expectations if proper habits are adopted consistently.

Conclusion: The Importance of Driving Habits

  • Ultimately, Ford diesels do not fail simply due to age but rather because of poor driving habits regarding warm-up procedures, idling practices, towing techniques, DPF treatment, fuel selection, and overall maintenance routines—highlighting that conscientious ownership is key for longevity in these vehicles regardless of model or mileage achieved thus far.

How to Extend the Life of Your Diesel Engine

Key Habits for Diesel Longevity

  • The longevity of a diesel engine is primarily influenced by the owner's habits rather than the engine itself.
  • Essential practices include warming up the engine properly before use to ensure optimal performance and longevity.
  • Avoiding idling is crucial; prolonged idling can lead to unnecessary wear and tear on the engine components.
  • Drivers should refrain from lugging the engine, which can cause strain and reduce its lifespan.
  • Cooling down the turbo after heavy use helps prevent damage and maintains efficiency.

Additional Best Practices

  • Short trips should be minimized as they do not allow the engine to reach optimal operating temperature, leading to increased wear.
  • "Toasting smart" refers to being mindful about how you operate your vehicle during warm-up periods.
  • Monitoring boost habits ensures that you're not overworking your diesel, which can lead to premature failure.
  • Respecting regeneration processes in modern diesels is vital for maintaining emissions systems and overall health of the engine.
  • It's important not to baby your diesel; it needs proper usage patterns to function effectively.

Conclusion

  • Following these outlined habits will significantly enhance your Ford diesel's lifespan, potentially outlasting even its owner.
