Mobil 1 grade

[Ken Lally]

Gents, have oil changes sheduled for both my silver bullets tomorrow early. I want to pick up the oil on the way home (no manual handy), just want to double check, that the '05 Viper is Mobil 1's 0W-40?

Does anyone know if the SRT8s use the same?

I thought it was 10w-30. Should say on your oil cap within the engine compartment.

yes, the newer vipers are 0w-40

 

[V10SpeedLuvr]

10w-30 is Gen 1&2. I'm not sure about Gen 3

 

[wormdoggy]

I have a gen 3 and its 10w-30. 2004 and 2005 should be the same.

With so many varying answers, I'd call Tator or one of our other famous and beloved Viper techs before you guess wrong

0W-40 is for 2006. I'm pretty sure Dodge recommends 10W-30 for 2003-2005.

I use 0w40 now with my 2003. It offers higher high temp viscosity than 10w30. It seems to be a win-win.

Factory fill on my '05 was 0W-40.

THE ANSWER: Starting with the 2005 model year...the factory fill became Mobil 1 0W-40.

Factory fill for everything up to and including 2004 is Mobil 1 10W-30. Mobil 1 0W-40 for 2005 and 2006.

Why the change?
Engine schematics were the same...........

Thanks

Actually they are not, the main bearings got changed in the later engines. Went to a 180 degree groved main bearing from the previous 120 degree groved bearing set. Daniel Lesser could provide more insight if needed.

Also, the oil pressure at idle is different on my dads 05 and my 06, then some friends 03's. I noticed that mine and my dads idle at 25-30 psi and the earlier cars did more like 50psi at idle. So there could be other differences that I dont know about that is doing this, or it could be the viscosity of the oil doing it(I doubt it).

I do not believe that the bearings were the sole reason to do it, I think its got more to do with the availability of that oil. Back in 03 I never saw a 0w-40 offering in synthetic. I think Dodge sees the value in the wider range, and changed accordingly. I'd think it would be perfectly fine to use the 0w-40 in the older cars, but I wouldnt claim to be an authority on such.

Here in the UK its difficult to get any 10/30. Main dealers use Mobil 1 in 0/40 fully synth and my 04 runs fine on this. Newer Corvettes run this also with no problems although book says 10/30 for them.

There were other posts about this that specifically warned against using 0-40 in 03's and 04's, I am just too lazy to go look for them...

I have a 2005 Mamba and with the help of steve from Indi. we both checked the manuel and the oil cap and both said Mobile 1 0W-40 for 2005.
Thanks Steve

0-40w is fine for the Viper, but will check ,as the 5.7 Hemis should only have 5-20W. Not sure on the 6.1 , off the top of my head , but will check and post in a bit.

 

[Bill Pemberton Woodhouse]

0-40w for both.

Wanted to make sure, and the 5-20W is for the 5.7 due to the MDS system, but figured it would be better to verify.

Good luck!
