So the other day I did a compression test and all the cylinders were running at about 90psi. I have a couple other things that I am going to test to make sure that I did it correctly. Anyways, say I have low compression that is about equal in all the cylinders. What are your thoughts on compression repair additives in the oil? Yay or nay? Good or bad? Problems with the additive in the turbo?   EDIT: The title of the thread should be "Low Compression". I just can't type.

I have an aftermarket oil pressure mechanical gauge, set up in my car. when I first start it up it reads 60lbs pressure until it warms up.   After warm up at 2,200 rpm at 70 mph (automatic tranny) it is reading about 30lbs.   At idle at a stop light it is reading from 0-5lbs. until I touch the gas a little.     What should I be seeing at idle, with a warm engine? The Car runs nice with no smoking. is there any other simple reason for low oil pressure at idle? I think it is about due for an oil
