My SS 3.8 liter just turned 100,000 miles. Should I go to a different oil-I normally use 10W30.

 

If you change oil regularly, and notice that it's not burning oil, then no need to make any changes.

You can safely take it down to 5w-30 though, if you live in an area with colder weather.

 

Stick with regular oil changes. There should be no need to change your oil due to the mileage. Myself and many of my friends and family got much higher miles keeping with a regular routine.

At 100K miles, you may want to check the suggested maintenance in our FWD Tech Info section.
