Just curious on why the Hemi has to have 5-20 weight oil and why this is so critical? Especially if you are using a fully synthentic oil.

 

Its what dodge recommends for cold starts. plus I have heared from people who have tried higher viscositys that the mds dont function correctly and they loose fuel mileage

 

I thought the 03-05 Rams are non MDS so why would that matter?

 

A technical service bulletin (TSB) - 09-015-04 and 09-013-04 - says: “Vehicles with the Multiple Displacement System must use SAE 5W-20 oil. Failure to do so may result in improper operation of the MDS.�

 

Exactly


Thought the 03-05 say 5w-30 on the cap? Moms 04 does.....

 

I use Mobil 1 and I change every 4k miles.

 

Mobil 1 5w-30 and a wix filter every 5000miles

 

Mobil 1 5/20
K&N Filter
3,000 miles

Maybe I should try Amsoil.

I received a notice from the dealer to get it in at 3000 miles but my service book that they told me to stick to say 6000 miles. I'm going with 3000 miles for now.... I still have yet to break the 900 mile mark so far.

We just bought a new Honda Accord and Honda said to Definately NOT change the oil the first time until 6K as they add special additives that they want to stay until 6K.

 

yeah I see it now, on my iPhone, but last night on desktop said Dana soft where the tea bag comment normally is.
