Yes first cold winter. Lighter than 10-30? I only have 30 psi when warmed up all the way. Engine is solid but has some wear on it. As long as it gets quiet when fully warmed should it be OK? Would you recommend 5-20? I suspect old heavier oil in the line to the gauge for slow pressure build. Does that sound about right? Maybe I am thinking this too much. Any thoughts are welcome. Thanks!
