i have a 2008 dodge ram 1500 hemi laramie with mds. it has about 106k miles so the warranty is up on it. it recommends 5w20 oil...
I do a lot of highway driving with it... average of 30k a year.. a lot of times I'm driving at least 85 or higher on cruise control. i buddy told me i should consider using 10w30 oil instead because of driving habits and the mileage. my book though says only 5w20 or mds will be messed up?
has anyone used different oil in a semi with MDS? is there any benefits to using the thicker oil if it won't hurt MDS?
