Electronics question

You can get a bypass oil filter that will filter out smaller particles than your regular filter does. It bleeds off a small amount of oil that passes very slowly through a much finer filter. It's an old trick that is still being used. The Amsoil guys like to sell them.

I don't think synthetic oil is so good you can extend it's drain interval way out. You may be able to extend it a little though. Most synthetics are blended with regular oils and not pure Synthetic.

A good test would be to run your regular oil to the normal oil change date, then test it. That would be your standard to at least equal with your extended drain interval. I wouldn't waste my money testing every 1000 miles, the oil will barely change in that small a time. 2000 or 2500 would be better and begin tests at the regular oil change time.

I don't use synthetics in any of my cars, including the Lola T70, I don't push the oil temperatures high enough to need it.
