Here’s Why 1990 Mercedes-Benz 420SEL Scheduled Maintenance Matters

When it comes to your Mercedes-Benz 420SEL, how you treat your car makes all the difference in its performance. If you put in the effort to keep up with proper maintenance, you could hit 200,000 miles (or beyond!) in your 420SEL.

It’s as easy as following the recommended maintenance schedule that’s been written specifically for your 1990 Mercedes-Benz 420SEL!

This recommended maintenance schedule is written by the auto manufacturer, Mercedes-Benz themselves. Driving conditions, climate variations, and other variables can affect which scheduled maintenance services you’ll need; in most cases, though, recommended maintenance will consist of services like fluid exchanges, filter changes, new brake pads, oil changes, and tire rotations. Keeping up with routine service appointments is a great way to keep your 420SEL running for longer, decrease your risk of dangerous malfunctions on the road, and prevent common 1990 Mercedes-Benz 420SEL problems.

Think you could be due for a new battery in your 1990 Mercedes-Benz 420SEL? In general, car batteries only last three to five years. Depending on the climate where you live and your habits while driving, your 420SEL may need a replacement battery sooner. Taking short trips or exposing your car to extreme temperatures (like in the dead of winter or heat of summer) could reduce the life expectancy of your Mercedes-Benz 420SEL battery. Sure, you could wait until your battery is completely dead, but it’s a much wiser decision to replace it before you need to. Otherwise, your battery could die unexpectedly, leaving you and your 420SEL stranded. Your Mercedes-Benz 420SEL could quickly go from being a trusty ride to a source of stress in a matter of minutes.

Remember, things like average outside temperature or frequency of trips could increase or decrease this interval for your specific vehicle. Talk to a Firestone Complete Auto Care technician to know when to change your oil. We'll also help you understand what type of oil to use for your 1990 Mercedes-Benz 420SEL.
