I just purchased an 05 4x4 Laramie with Cummins and 6speed manual and I need to figure out how to tighten up the parking brake, the way it is now it does next to nothing when pressed in all the way. Sometimes I drive around and then notice I still have the parking brake engaged thats how loose it is.

Also, what kind of oil do these engines take? Is it any different then a gas? First time dodge AND diesel owner, so I am clueless. I want to put an Edge chip in it in the future, if that makes any difference. Synthetic or not?

Any help would be greatly appreciated.

 

OK nevermind the parking brake. I already tightened them.

 

You should use an engine oil that is rated CI-4+ or CJ-4. CJ-4 was designed for newer diesel engines like the 6.7L Cummins, but is also fine for older models.

I would suggest an Amsoil synthetic or synthetic blend oil. Their AME synthetic or PCO synthetic blend would be ideal for your engine. Check this link: http://www.amsoil.com/products/heavytrucks/index.aspx

 

Could you please explain what that means? I know what regular oil like 5w-30 means but what does CI-4 or CJ-4 mean? oh wait a minute, I think I remember C is for diesels, and J is the quality or something like that... and 4 is a group as in natural oil or synthetic... i just forgot what group was what though...

Am I right?

I am probably going to go with Royal Purple if they have the oil I need...

i did use the amsoil because our local parts store had it, surprisingly...

i used this exact one https://www.amsoil.com/storefront/ame.aspx

i also changed the fuel filter and air filter also along with the oil filter. she should be good to go now for a while. she's got a lot more kick now in the higher rpm's
