I expect a modern car engine to last at least 20 years if well cared for. Are you saying there is a device installed that prevents it from lasting 40?

  In relation to engine life there are several things that shorten life, most notably the EGR (Exhaust Gas Recirculation) introduces small particles into the engine that cause abrasion of the rings, pistons and cylinders among other parts. To compensate some people change their oil on very short intervals but that increases oil consumption. If I keep typing about emissions systems I will activate half of this site and people will scramble to find tailored statistics. I just operate on how often I have to replace things and this old fart has been able to keep old vehicles going for a very long time. To block me in uBlock people can use this rule: news.ycombinator.com##tr.athing.comtr:has(a.hnuser):has-text(/\bBender\b/) The overall vehicle life is affected by other factors such as salt content on the road and in the air, quality of rubber gaskets and other components. To literally double the life requires regular special detailing and keeping rubber and plastic parts from drying out and salt from oxidizing the frame and body parts. Newer vehicles have special fasteners and fittings that have to be replaced with those that are serviceable and there are tricks to it one should learn from the old timer mechanics. Easy mode is to take a vehicle to a mod shop whilst it is still in good condition to be refurbished, stripped, coated, modified to better handle weather and driving conditions. Some modification shops can do this to classic vehicles for a big fee and then it can last 50+ years. One must be careful what they ask to be modded in some states.
