5w20 OR 5W30?

[bedwards6954]

so had anybody acually called the dealer service department and asked them?

I mean really a slight change in engine oil weight is going to void your warranty?

I just had my 8 in for an oil change and asked for 10X30wt and thats what they wrote down and put in no problem.

I have been using 5w20 for two years now. No issues. I do change the oil every 3k miles on the dot. Mobil 1 Full synthetic every single time.

After doing much reading, I will be switching to 5w30 when I use the last of this w20 I have laying around. My MPG sucks anyway. I doubt this will make any difference.lol
