My '93 F250 4x4 does not smoke, other than a small amount when starting, and runs fine. It does, and never has, gotten very good mileage. Like, 12 mpg on the average. I am running it now in Ca. which is suppose to have a cetain rating of 50 or so.. It has 220,000 miles, and seems to not have the power it once had... well duh, its getting older. I was wondering if I do a compression test, just how many pounds of compression should it have?
