3447dc oil

[ERCAN]

I have 3447DC Engine

I was told to use 10w-30 Synthetic oil.
Where I am at I am having hard time finding this type as sytnthetic.
There is 5w-30 Synthetic oil though.
Can I use 5w-30 full synthetic instead of 10w-30 synthetic as a substitude?
Can I use regular 10w-30 oil which does not specify wheather it is synthetic or not?
OR what other options do I have to use as oil for this engine?

Also for water pump I can not find SAE-30 type oil as non-detergent non foaming.
I found SAE-30 oil but it does not specify non-detergent and non-foaming on the container is that a problem?

What type of oil do you use in a Kohler engine Truckmount?

Can I use 5w-30 full synthetic instead of 10w-30 synthetic as a substitute? (I think this would be OK though the owners manual does not clarify if it really is ok or not. The 5W is for use in below freezing weather.)
Can I use regular 10w-30 oil which does not specify wheather it is synthetic or not? (yes)
I found SAE-30 oil but it does not specify non-detergent and non-foaming on the container is that a problem? (Yes. This is not OK. You might also try to locate air compressor crankcase oil. This is the same stuff with a different label.)
