Know nothing about this car yet. Need to change the oil on an 83 300D. How much is needed incl filter change. I'm putting in 20/50 for summer, castrol or pennzoil, or meybe Wall-Mart unless I'm told other wise by the group. I noticed some moisture on the fuel filler cap when I filled up the other day. I sort of suspect this is OK for a diesel car and am asking should I be putting any kind of fuel dryer in the tank or just leave well enough alone.
thanks for you continued help.
