How to Make a Car Last 300k Miles

·1 hr 8 min·5 clips
A certified master mechanic claims coasting and specific fuel additives are key to making your car last 300,000 miles.
The episode begins with hosts Scott and Ben introducing the topic of high-mileage cars, sharing personal experiences with vehicles reaching up to 260,000 miles. They reference David Solomon, a certified master auto mechanic from Butler, Maryland, who authored a list for Bottom Line Inc. on achieving 300,000 miles. The list is divided into driving techniques, fuel choices, routine maintenance, and helpful tips. Under driving techniques, Solomon advises coasting, accelerating slowly, allowing the engine to get hot with highway drives, and avoiding two-footed driving. The hosts debate these points, with Ben admitting to downshifting for enjoyment despite Solomon's recommendation to use brakes instead. In fuel choices, Solomon suggests using gas additives with every fill-up, sticking to the recommended octane, and not letting the fuel tank drop below a quarter full. The hosts express skepticism about additives at every fill-up but agree on octane and fuel level advice. Routine maintenance includes determining part life expectancies, rotating tires, and using AGM batteries. Solomon provides specific intervals for changing fluids like oil, brake fluid, and transmission fluid, which the hosts note vary by manufacturer and driving conditions. Helpful tips include keeping few keys on the key ring to avoid ignition wear, using car covers, and analyzing oil with test kits. The episode concludes with reflections on build quality, luck, and emotional attachment to cars, inviting listener feedback on the list's recommendations.
