“Good compressor, but pressure doesn't stay at 150”

Craftsman Professional 25 gal. Air Compressor, 1.8 hp, Horizontal Tank — 

I bought this compressor around Christmas 2007. This model (919.195411) had the old specs (2HP running, 8.6 CFM @ 40 psi and 6.8 CFM @ 90 psi) printed on the tank and on the belt guard. As stated in the manual, this one was shipped with no oil in the pump, so I had to buy a 16 fl. oz. bottle to fill the pump prior to the break-in procedure. It took a few minutes to slowly add the entire 16 fl. oz. in the crankcase. After the 20-minute break-in, the motor stopped at cut-out pressure of 150 psi. I noticed the pressure dropped very quickly to 135 psi in 30-40 seconds, slowly bled down to 130 psi in 4-5 minutes and stayed at 130 psi. Suspecting there was a leak, I sprayed soap water and found a very very tiny pinhole leak at the weld of the main fitting (large hex nut) to the tank where the check valve is connected to. I let it sit there for a whole day and the pressure didn't drop any further. Thinking that a tiny pinhole was the main cause for the initial drop from 150 to 135 psi in 30-40 seconds, I decided to return it and exchange for a new one. After opening the new box, I noticed a change in the specifications. The new model (919.195412) is rated 1.8HP running, 7.4 CFM @ 40 psi and 5.8 CFM @ 90 psi (* tested per ISO 1217) and shipped with oil already in the pump, ready for use (this can cause oil leaks if the box is not properly placed, e.g. laying the compressor on its side or upside down). This one had the same problem: after cut-out, the pressure immediately dropped from 150 to 135 psi , slowed to 130 psi and stayed there. It also had a leak at the main fitting, albeit not because of a bad weld, and was located in the outside thread of the large nut and the tank. This leak was so small that I could hardly see the bubbles with soap water. Just want to test it, I let it sit there for 2 days and the pressure didn't even drop below 130 psi. Still, I wanted to get a compressor with zero leaks and no pressure-dropping problem, so I brought it back and exchanged for another one. This third one has no leaks and is the same model (919.195412, 1.8HP, 7.4 @ 40 and 5.8 @ 90). But it still has the same problem, pressure dropping after cut-out. This seems like it is a common problem for this compressor and I'm surprised that no one had seen this and mentioned the issue in the reviews. This compressor runs on a 20-amp outlet without tripping the breaker and is very quiet. It goes from empty tank to 150 psi in about 4 minutes and recovers fairly quick from 120 to 150 psi in about 1 minute. If not for the pressure-dropping issue, I'd give it another star. I've not mentioned this: For all 3 compressors, I did have to tighten up all fittings and connections at the check valve, unloader valve, drain valve, etc., to ensure there're no air leaks. Although the first 2 compressors had very small leaks that couldn't easily be fixed, I don't think the leaks cause the quick pressure-drop after cut-out. With leaks or no leaks, they all seemed to stabilize at 130 psi. If any of you had seen this with your compressor, please share your thoughts/solutions.
