I know this question has probably been asked here a hundred times, but I can't find a relevant thread so I though I'd ask again. Please bear with me.
The workshop handbook for the Bugeye Sprite calls for 20W30 (conventional) oil for both the engine and the transmission. (This is quite different for other LBCs like the TR3, for example).
But from what I keep reading, 20W30 is generally described as a gear oil (?) and it is hard to find in local stores. Some say it can scratch internal engine parts (??) and causes trouble for the oil pump.
A number of people have told me that they use 20W50 conventional oil (sometimes adding some ZDDP, although Castrol 20W50 apparently has ZDDP in it). 20W50 is easily found in local auto stores.
Some say that they use 10W30 because the 20W50 may be too heavy in the winter.
Here in Virginia, it usually doesn't get too cold in the winter, and I never had trouble with my TR3 running Brad Penn 20W50 semi-synthetic, winter or summer.
So,my question: How many of you use 20W50 conventional oil year-round and find that it works fine.... in the engine and in the transmission?
Sorry to bring this up again, but it is hard to find a clear and direct answer to this question on the Internet.
