Hello All
I recently purchased a '92 240DL with 156,000 miles on the odometer. I also own a '89 740.The 740 has 289,000 miles on it. They both have the B230F engine. My question is why will the 740 run circles around the 240. Since the
740 is a much heavier car I would have thought the 240 would be the better performer of the two. The 740 accelerates much better than the 240 and gets better fuel mileage.25MPG verses 23MPG. The 240 has been tuned up with new plugs,distributor cap and rotor,plug wires and had the injectors cleaned. A compression test was done.All cylinders are 160 PSI.Still it does not have the zip of the 740 that has twice the mileage of the 240. Anyone have any thoughts on this?Thanks Larry
