I just found 1 quart of Penz SG 20W-50. This was in my basement so I have no idea how old it really is, the bottle has not been opened.
I have a 1988 subaru Justy with over 252,000 miles. What do you all think about using this oil with auto-rx and 10w-30 valvoline, the oil capacity on this car is just under 3 quarts, the car has a sludge problem and I will be only driving 1000 miles on this application.
Thank you.
