I just changed the oil in my 2015 5.7L for the first time since I owned it. I was in touch with the previous owner and he used regular 5w-20 but changed it every 3000 miles religiously. I used Valvoline Synthetic 5w-20 and I'll change that again in 3500 miles. This is my first Ram 1500 pick up and I love it! The ride is nice and I was lucky enough to get the hemi engine. One more question though; does anybody know what bulb goes into that marker light underneath the mirrors and how to change it? I can't seem to find it in the manual. Thanks guys and gals, $Bill.Hello there,
When the 'Change Oil' message appears on the dashboard, how soon should oil be changed? Within a week? Oi level is at the lower end of the 'Safe' indicator.
