I have seen lots of discussion on what oil to use in carbs. I have not been able to find straight 20W in any of the local stores and I have resisted buying one quart (only one since low usage) via the internet. My daily driver car uses 4-1/2 quarts of 5W/20 Castrol GTX oil per oil change and never burns any between oil changes. So I am wondering if I can use the left over 5W/20 oil in my SU carbs on my TR3 and in the Strombergs on my TR250?
Thanks! Bob
