Gas or diesel, if you do proper maintenance both will provide for a long service life. A gas engine will likely last about half the total miles of a diesel. So where a well maintained gas engine will likely run for 300 to 400 thousand miles a diesel will likely go 600 to 800K, given the same level of care. The Mercedes-Benz ML350 is a durable SUV that can last between 200,000 – 250,000 miles when adequately maintained and driven conservatively. Based on an annual mileage of 15,000 miles, you can expect the Mercedes ML350 to last 13 – 17 years before requiring expensive repairs or breaking down. Your automobile’s gasoline engine should typically last for roughly 200,000 miles before needing a significant refurbishment or you need a new car. However, diesel engines may operate continuously for an amazing 1,000,0001,500,000 miles before needing any significant maintenance. A8. 31. Audi is giving its A4 and A6 models an end date as combustion engines. The same is said to apply to the A8. Even in plug-in hybrids Audi apparently no longer wants to invest heavily. These decisions are likely to be the cornerstones of the exit plan from the internal combustion engine drawn up under Audi CEO Markus Duesmann. The V12 TDI engine was "based" on the diesel technology from Audi R10 TDI race car, though both engines are completely unrelated: the bore / stroke / angle of the blocks are different and they do not share a single component. The only twelve-cylinder diesel engine used in any passenger car, it was rated at 500 PS (368 kW; 493 hp) and 1,000 N⋅ Car engines don't really last that long. If you assume that a car travels at an average speed of 25mph (probably about right these days.) then 25000 miles equates to 1000 hours of running. 100,000 miles equates to about 4000 hours. There are about 9000 hours in a year, so 100k is less than 6 months continuous running. C-class is expected to last for 200,000 to 250,000 miles on average, which is higher than Audi A4, which lasts up to 200,000 miles. The maintenance cost for C-class is $908 annually, whereas, for the A4, it costs $739. Repairpal rates both C-class and A4 3 out of 5 for reliability. J.D. Power places the C-class at 79 out of 100 while the A4 is 4. How Long Do Glow Plugs Last? If your vehicle is powered by a four-cylinder engine, one bad flow plug will make the process of starting your car hard. 2 faulty glow plugs will add to the struggle while 3 or more will make the job impossible. On average, a diesel glow plug will last roughly 100,000 miles. .
