What grade of synthetic oil should I use in a 4.7 ltr Durango?? Ie. 5-20, 5-30, 10-20, 10-30 etc.

 

Same grade as you'd use with regular oil, they use 5w30.

 

yup same as regular, stick with the 5w30

 

What kind of filter can you use with synthetic, i use mopar or wix. How often should it be changed?

 

filter must be changed with every oil change, some say to change it in btwn at 5k mile intervals but as long as your oil change is under the factory recommended 7500 miles i wouldnt worry about changing it any more often than the oil

 

I have heard/seen on bottles for many miles something like 10,000 to 25,000. Just change the oil filter

 

The 1st Gen Durango had a recommended oil change interval of 7500 miles from the factory?

 

the 2nd half of the generation with the 4.7 did, im not sure about the 98-00s but 01-03 definitely i would personally never run it that long, but dodge says its ok

 

Where did you get your signature from???

I saw a cartoon in Field & Stream or Outdoor Life many years ago that said exactly the same thing. with a helicopter lifiting a Jeep out of a swamp. Never forgot it.

Thanks a lot for the info guys, I think I got the picture. 5-30 And I change the filter and oil every 5 to 6000 miles. I'll try Pennziol Syn.

Thanks again
