Inthis podcast episodeof CarStuff , hosts Scott Benjamin and Ben Bowlin receive guest Matt Frederick of Stuff They Do n’t Want You to have it off to search what it takes to make a car last 300,000 air mile ( 482,803 kilometers ) . Is there a " Goldilocks zona " for turn out tyre and interchange fluid that will result in a vehicle ’s peak performance over prison term ? And could it pass to reaching the 300,000 - sea mile marker ?

These are difficult questions to answer , considering that mileage alone is n’t the only indicator of a car ’s seniority . A someone could drive30,000 milesa year ( the average is 15,000 ) and rack up international nautical mile moderately quickly , but someone who drive very little will still see their motorcar age when the interior fades and rubber constituent begin to dry .

David Soloman , a certified master mechanic and editor of MotorWatch , contendsthere are several thingsyou can do to prolong a fomite ’s lifespan — and extend its milage .

The first strategy is n’t about the car — it ’s about you . Adjusting the means you drive is a great way to take tenseness off a fomite . Coast as much as possible by planning your approach to lay off signs and intercept light before hand them . As a outcome , you ’ll avoid abuse on the brake at the last present moment , which wears the brakes down . Avoid heavy acceleration ; stepping hard on the gas pedal when the engine is cold is the main reason an railway locomotive ’s headland gaskets fail .

And here ’s a baffling one : Do n’t turn over on the heater or air conditioner straight off after you start the locomotive . The excess load will wear the engine down . However , you should start the breeze conditioner or windshield defroster at least once a calendar month , no matter the atmospheric condition , to keep oil circulating through the warming and cooling system .

It also help to ante up attention to the possessor ’s manual formaintenance guidelines . If you fill up with agiotage fuel , but your fomite ’s engine is designed for regular , you ’re wasting money , and it could cause a build up - up of carbon on the combustion chambers . Speaking of petrol , you should n’t let the amount in your storage tank drop below a quarter of a tank . When this happens , it can cause condensation and damage the fuel pump .

How many time do you keep adding gasolene after the nozzle clicks off ? catch the amount to an even number or take a leak the most of your fuel points may have more trauma than expert . You ’ll damage the evaporative emission canister , which can cause the " check locomotive engine " light to hail on and lead down a rabbit hole of expensive fixture .

If you really want to make your vehicle last , pay attention to the routine life expectancy of major part — and supervene upon them before they fail . To this remnant , it helps to circumvolve the tyre every 7,500 miles ( 12,070 km ) , get the shelling examine annually and have the oil and other fluids deepen like clockwork according to the owner ’s manual of arms .

Oh , and that giant key ring weight down with every key you own and more than its fair share of dangling décor ? Ditch it . In some vehicles , the extra weight can even affect the ignition electric switch .
