Tips to Make Your High-Mileage Mercedes Last

Keeping your high-mileage Mercedes in good operating condition is essential to prolonging its lifespan. We wish that it was as simple as not driving so much, but the number of miles in the commute to and from work is impossible to change. However, with proper care and diligent Mercedes maintenance, you can keep your Mercedes running smoothly for years down the road.


The absolute be-all, end-all to keeping your high-mileage Mercedes healthy is regular maintenance. Servicing your vehicle at the proper intervals will help to avoid all kinds of problems—both big and small—in the future. Most of the bigger issues we see here are direct results from lack of proper, regular maintenance. Things like transmission failure, misfire, and worn brake rotors are all completely avoidable.

Generally, newer engines can handle more miles between servicing. The parts are newer, there's less wear and tear, and everything runs smoother. The more miles that an engine packs on, however, the worse its day-to-day performance will become. Servicing intervals for vehicles becomes more and more critical as the engine ages. Higher-mileage Mercedes absolutely require more care to keep them running safely.


Many factors lead to older engines requiring more strict maintenance than newer engines. Here are a few of those factors.

  • Small, gradual problems can build up over time and create a domino effect that leads to much more serious issues.
  • Blow-by gases increase in older engines, which leads to oil being diluted quicker, which leads to more oil changes.
  • Fuel filters and oil filters are less effective over time, which can ruin injectors and damage the entire fuel system.
  • Spark plugs don't get replaced, which can cause misfires and potentially damage the catalytic converter.

Sticking to your scheduled maintenance helps avoid all of these major problems and many others.

Remember, you will never save money by skipping a regularly scheduled service appointment.

In the end, the problem will become worse and worse, and will end up costing you much more in repairs in the future. Maintenance is an effective way to keep your car safe for the road, while saving money and investing in the future value of your car at the same time. Something as simple as keeping the proper air pressure in your tires can lead to a 3-5 increase in MPG. So, why wait? Contact us to schedule an appointment today!
