I have installed a full-flow oil filter on my A. It is the one that mount on the valve cover and sticks out horizontally. The output tube from the oil pump is extended and goes directly into the oil filter.

On first startup, the filter is empty and has to be filled up by the pump before any oil goes out to the engine. I have seen someone on this forum estimate that based on measure pump outflow rates it could take 2-3 minutes of the engine running to fill the filter.

My question is how to best handle this period of "dry" running to minimize wear. I have had two suggestions that I like:
1. dump a couple of quarts of oil in through the distributer hole just before startup and;
2. put only enough gas in the tank to run 2-3 minutes and add a little 2-cycle oil to the gas.

What do you think? Is there better way? Am I making mountain out of the proverbial molehill?

Thanks.
Jim
