Default Poll on oil weight you use in your 5.7

I am curios about what weight oil everyone is using.
If you would please enter what weight of oil you use, or if choosing other, then please post the weight you use.
I tried to get enough options for most weights of oil, but there is always others out there for sure.

Use what is called for, 5w-20 or you might see problems. There is a thread somewhere about it. It messes with the MDS...

Yes, since the MDS is oil pressure activated a change in weight can affect the MDS performance, or in some cases puts stress on the oil pump due to it having to work harder/spin faster due to a heavier/lighter oil respectively.

Incorrect oil viscosity can set a code in the PCM and turn on the MIL.

5W20 or 0W20, that's all you should be using in an MDS engine period ......

I just want to add that mine runs perfectly on 5w30.
Its only going to be a little thicker once the oil is very hot, but at start up and moderate temps is the same viscosity as 5w20 is.

When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. (SAE oil is tested differently) 5w is the weight at cold, 10,20,30 ect is the weight at operating temps (not very hot). So 5w20 and 5w30 are not the same thickness at operating temps 20 will be thinner.
