I'm thinking of going with 0W-40 in a Durablend and sticking to 6K miles with a regular STP filter every 3K miles. Then just top off.


Prior to that I'd buy a 5qt jug of what ever was on sale with the SAE seal and Mix and match if I needed an extra quart.

Mobil 1 says:
Today’s modern vehicles require a less viscous oil in many cases than in the old days. Having said that there is no harm in mixing different viscosities.

 

I try to change mine every 3000 miles but end up doing it closer to 4000. Hardly ever go longer than that.

 

6k or 6 months, usually it's 6 months as I'm averaging about 8k a year since I bought my Grand Cherokee for a daily driver in '06. Full Synthetic (I've done Royal Purple for the most part but I caught Valvoline on a sale last time that was too good to pass up. Filter is usually a Wix, but I've used Purolator Pure-One and Mobil 1 filters on occasion...

 

About every 10k give or take a few thousand. So maybe twice a year. Oh no my 4.7 is sludging what a piece of crap!

 

schaffers, mobil, valvoline or pensoil (all full synthetic) every 4000 unless it starts to darken, then sooner. schaffers seems to be the cleanest after 4000

 

Dodge has been fairly specific on the 06 and up Hemi's with MDS requiring 5W-20. It seems to be more picky then the non-MDS motors?

I change mine every 3k miles, which takes a while since it doesn't get driven a whole lot.

 

I change mine every 3k religiously even though it says I can go 5-10k.

 

every 3k

 

every 6mths rounds me out to about 5-6k on both my cars, use mobil 1 everytime, filters usually mopar or mobil 1, and for the turd usually a fram or purolater....

 

ive been on 3k now im doing 4k but thinking of switching to 5k once i hit 80K (next oil change) ive been using any synthetic that is on sale at the time, in a pinch ill use fram but prefer mobil 1
