i need to change my oil and i dont know what kind to use....is it 5w 30?
what do u use. i lost my manual so i cant check.

 

5w30 if yours doesn't leak oil or tick. if it's got noisy lifters or leaks oil, then use 10w30.
when it gets cold outside, switch back to the 5w30.

 

since it never dips below the 40s here in FL, I just use 10w30 year round.

 

what are the benifits of using 10w30 over 5w30?

 

unless it drops below 0 10-30 will work fine. I use high mileage on mine .

More info about oil than you can handle.

 

I personally run 5W-30 dino year-round since I change my oil so frequently. However, when the cold-azz winter months hit, I sometimes will use 5W-30 or 0W-30 synthetic.

The manual recommends 5W-30. The brand is up to you. If you want more info on oil, see the link in the above post.
