I don’t think you are in trouble yet. As you say it is cold and your running 30wt. Go ahead and throw an old blanket over the engine and put the heat lamp under the pan. Don’t leave it unattended or change it to a 100 watt bulb. If your getting 15 lbs at the gauge I’m guessing you will get oil to the rockers. Your engine is not a full pressure (I think) and so the amount of oil will not be massive. You got this.🛠
