no
You can, but I would not recommended. Due to it's not a new truck and high mileage. You can put 10W30 or 10W40 instead. I think the 5W30 may hurt your engine.
yes,it will not hurt it
If that is NOT the recommended weight as listed by the manufacture in the owners manual then it would be foolish to use 5w30. Use exactly what the manufacture recommends and nothing else.

Yes, it will hurt. Honda designed and built the engine and they recommend SAE 5w30 oil. So there is your answer. Use what Honda recommends and nothing else. To do otherwise would be foolish.
i have read on forums that you can it doesn't hurt.
You should drain the oil in the engine. Put engine oil back in the engine because the transmission oil is not made for engines and will hurt the moving parts of the engine if left in.
It won't hurt the engine but it will hurt the catalytic converter.
It does not hurt an engine to run it with no exhaust muffler
it wouldn't hurt to mix the oils, I mixed 5w30 and 10w30 in my 1986 Lincoln town car because 5w30 bled right through, seeing as it leaked from everywhere, I probably went through a liter a week. Straight 10w30 leaked maybe a liter a month, but caused the engine to run much rougher. After mixing the two, I went through a liter every 2-2.5 weeks and the engine ran fine
Regular oil is recommended by Jeep. Edit: Correct, Jeep does not make a recomendation to use synthetic oil. However synthetic oil will not hurt the engine at all. The recommended weight is 5w30.
It is a 4 stroke engine. Only use that mixture on 2 strokes. It won't hurt it but you will have alot of smoke and eventually build up. So no. straight gas and 5w30 or 10w30 oil in block.
