You need to manually check the oil pressure with a gauge. Of course you have to find the sending unit to do this, and maybe it'll just be a broken wire or bad sending unit.

The green color is a break in oil additive.I have never did the first break in oil change on a GM vehical.But I have seen this on small engine like Kohler.First I thought Oh no antifreeze in the oil.Until I realised the Kohler was air cooled.GM uses the pink antifreeze so your also safe. Also when you change oil the first time.Its normal to see a metalic grey color and resembles graphite.Thats the filings and is normal and the green additive is to help remove them. The oil filter was tight because the factory does not put a small film of oil on the seal and also the filter base plate is dry and oil free at time of filter installation. Im not sure what oil they use at the factory.But GM Goodwrench oil I think is distributed bottled from Valvoline oil.

i operate a sawmill milling ponderosa in South West CO.. I've used a rough guess of about 65/35 oil/deisel mix on all my fences, posts, sheds, carports; anything I build NOT attached to my home. works great. I was told by a painter friend yesterday that the problem is there is no UV protection using this mix. He aslo said he went to a home that stunk to high heaven after many years of using used oil on it's wood. I have had no experience with it smelling bad. Sure, a few days to evaporate diesel and it's got almost no smell at all. I will continue to use this mix. The reason for adding diesel is only to thin out, allowing it to more easily/quickly be absorbed into the wood. in my experience rough cut lumber/siding absorbs MUCH better than planed (smooth) lumber. Though planed lumber WILL absorb the mix, it tends to do so very slowly. I find for nice fences once a year is required. Siding, maybe aevery feew years. I got a 55gal drum of used oil form a local shipping container company... I found out after I had my teenager stain the nerw shed I built, that is likley had miuch more than motor oil mixed into it. It was almost black. Guessing there was tranny and hyrauldic fluid in there too. I'm gonna find out from the guy who runs that operation. I'd rather not be putting hydraulic fluid on wood. That's dangerous shit I'm told!

I thought I was the only crazy one. I bought a mingle iron back in June. Before buying it I plugged it in and it seemed to work just fine. I did notice some oil on the right side where the motor is. The woman said the iron has been down the basement since she bought the house from 20 years ago. We logged it up the basement steps and into the back of my van. Given that the mangle iron Is very heavy, “ 150, 200 pounds,” we plugged it in again before removing it from my van. It worked. I was so excited, I thought I found a treasure. So we manage to get it up a flight of stairs and placed it across from my washer and dryer. We plugged it in and it started smoking. That was in June, I haven’t done anything with it since. My dreams of having iron sheets, tablecloth, napkins went up in smoke. I have spoken to a man in the neighborhood who works on old motors he said he would work on it for me but I have to get it to him. I’m not sure how to remove it. So, What worked for you?
