you can buy the oil from the dealer too. it costs more, but at least they have it. and you'd still save some because they wouldnt be charging the labor. you'd also make sure i was done correctly. some places are known to reset the oil change light and not actually change the oil. chances are the owner would never know.

 

oh my bad

 

I can wait for that I'm going with mobil 1 when it comes to it//....Uh oil change light? wtf is that ?? this thing comes on after 3k clicks on the speedo??

 

I think most Wal-marts have 5-w20!

 

Any local Lube place is gonna have 5w-20, no need to pay double at a Dealer.

 

Actually, After Coupons that I get every couple weeks or so, I can have the oil changed at the dealership for just about what it costs me to buy the oil and do it myself. I have done that a few times.

Usually though, I just buy the 5 gallon jugs of Mobile1 synth 5w20 from wally world and do it myself.

 

The only 5W-20 i have a hard time finding is RP.And that is the only kind that my Hemi doesnt eat or tick on.I tried Mobile and it drank almost 2 quarts in 3K miles and ticked every time i started it.I found Rp like 1 hour away and that did great,No useage and no tick.I changed to Castrol the other day cause i wasnt gonna travel 1 hour for Rp.So far no tick.I will see about the useage in a few more weeks.

I cant believe u cant find 5W 20 though.Its pretty common here and i live in no mans land.I know the new Fords use it as well so its not like we are the only ones.Walmart,Advanced Auto,Napa,they all sell some kind of 5W 20 .

 

My owner's manual and the oil cap on my 2005 Hemi says 5w-20, and it's NOT MDS.

 

Yeah, even my golfin' buddy who is a service mgr. at a Dodge dealer can't figure that one out. The '04 & '05s are the same truck with the exception of a couple of PCM "tweaks" and the '04 calls for 5w-30 and the '05 calls for 5w-20?

My bad in not including the '05s, although my personal rule of thumb is 5w-30 for a non-MDS and 5w-20 for an MDS Hemi. Although I do run a full synthetic 5w-20 myself in my '04, but I do so because I am running my engine cooler than stock (180* to richen my mixture which is leaned out a bit via Tuner, CAI & LT headers).

I don't think you can really go wrong running the 5w-20 in a non-MDS, but I wouldn't tempt fate (or lifetime powertrain warranty) and run 5w-30 in an MDS model.

Just my personal opinion...

 

Getting into discussions about oil is just as bad as "Who are you voting for?" or "This beer is the best". I don't know when 5w-20 hit the market, but I do know that at some point in recent years after 5w-20 came out, Ford has retroactively recommend 5w-20 for the small v8 (4.7?) when it called for 5w-30. I think the driving factor for the lighter weight oils is fuel economy, and my hope is that that the OEM's are not sacrificing engine longevity just so they can comply with government CAFE standards for fuel economy.

I would not put 5w-30 in the MDS engines when it calls for 5w-20. Going with higher viscosity without understanding the mechanics could cause problems in the long run. It was common practice years ago to put higher viscosity of oil in engines that burned oil, street raced, or just generally abused your engine. It's been many years, but I took an Internal Combustion Engines class in college and I remember a homework assignment where we had to calculate the maximum oil carbon chain globule (or something like that) and compare it with the nominal bearing clearance of different engines with 20w-50 oil. I'm exaggerating, but it was like trying to push a softball through a coke can. I changed out the 20w-50 in the crankcase of my SBC Camaro for 20w-30 that weekend.......
