‘03 is300 burning through oil in ~150 miles

I bought an is300 last summer and finally started driving it these past 2 weeks, put 150 or so miles on it and my oil light came on, meanwhile I just did an oil change before putting it on the road with 5w30 synthetic oil. I also changed out spark plugs and they were pretty fouled and covered in oil. Also did a compression test and it read 180lbs a cylinder (likely due to the oil)Just trying determine what is actually wrong, whether it’s my valve cover gasket, piston rings or possibly something else?
