How many years can a diesel engine last?

Diesel engines can often last 20 years or more, well beyond a typical gas engine, when they're properly maintained. That longevity comes from their heavy-duty build, but it depends heavily on staying on top of oil, fuel, and filter service. Bring your diesel to Duffy's Auto Service in Saint Paul Park and we'll help you get every possible mile out of it.

Is it bad to drive my diesel only for short trips?

It can be, because short trips often don't let a diesel get hot enough to burn off soot and complete the regeneration its emissions system relies on. Over time that leads to a clogged DPF, more frequent warning lights, and buildup that shortens component life. The expert team at Duffy's Auto Service can check your system and, if short trips are your reality, help you keep your diesel healthy anyway.

What's that white or black smoke coming from my diesel exhaust?

Exhaust smoke color is a useful clue: black smoke usually points to a fuel or air mixture problem, white smoke can signal unburned fuel or a coolant issue, and blue smoke suggests burning oil. A little vapor on a cold start is normal, but persistent colored smoke is worth diagnosing. Call Duffy's Auto Service at (651) 459-9052 and we'll read what your exhaust is telling us and pinpoint the cause.
