Third Day With Amsoil

Friday, September 28, 2007, I open the garage and move out my scooter. Then I turn on my scooter and leave it alone. But my scooter ack strange than two days ago. The idle RPM is increasing easily, it seems like the auto choke work better than before. I didn't hold the throttle to make the RPM increasing.

Yesterday I didn't notice about this, but last thing I remember is, this kinda strange also happen yesterday. As you know, I already complain to the dealer about the choke that didn't work correctly. But the dealer said it just fine, nothing wrong with the choke. With this oil, it fix the auto choke problem. I do not know how did they do. Maybe because the oil film that protect the engine better than before, so that make the friction point very low. Because of the friction is very low, the piston can move easily too. So this make the whole system work more lightly.

I run my scooter until 60kmh, the engine vibration is very low. Even when I run until 80kmh. I must go further to test it, but a heavy traffic is headed near by. So I must slow down and forget to test the top end power.

Last thing is, the engine deseleration is not like before. Now the RPM fall more slow. This mean the engine power will not drop as fast as a free fall when I close the throttle. But the side effect of this is I need to brake more accurate and a better braking system. May be I should change my braking fluid with a better one and check the whole braking system.

I'm getting more curious about this oil. What kind of another strange thing that this oil would do to my scooter engine.

Testing Amsoil MCF 10W-40

Friday, September 7, 2007, I buy an AMSOIL MCF 10W-40 right after an office hour. It rained outside, so I would have some problem getting this oil from the dealer.

After I get this oil, I contact my friend that I had one for him. He said, he will wait for awhile until his scooter get the right trip to change the oil. OK, no problem, me too.

Wednesday, September 26, 2007, I open the garage and move my scooter to the open area. I drain the oil and fill the brand new amsoil to it. But it still in the morning at 04.00 AM, my eyes and my mind still not work correctly, and it happen. I pour the oil to much about 850mL. It should be 800mL, because the engine could hold upto 900mL.

I think I will stay with 850mL, because I would test it for 6000 kilometer first, and see the result. What will happen to this oil. For my concern, amsoil recommend oil drain interval for this oil is twice from the factory default, which is 4000 km. But I said to my selves, hey this is synthetic motor oil, it should be more than that. Amsoil recommend that interval for a harley davidson 1000cc motorcycle, while mine is 125cc scooter.

After packing some stuff, I'm readdy to get to the office. I turn on the engine and wait until the engine ready. It's test time!

I open the throttle as usual, I don't sense any different from this oil compared to the last one. May be this oil is not working yet, or may be because I fill it to much. But something different about my engine. It sound very quiet now, Even when I open the throttle in a rush, still, the sound so smooth. I like.

After a couple of kilometer, another strange happen to the engine. The idle RPM is increased about 150 RPM from before. I do not change any setting on my scooter, I only change the oil. This is kinda interesting for me, how come an oil can increase my engine RPM. My conclusion is the oil is more superior in lubricating the metal, so the friction point is decreasing. That make my engine work more light than before.

Lets try on a stop and go condition. I run my scooter lightly to test the acceleration. Suddenly the RPM is increased rapidly, differ than before. Right now, I'm a stranger on my own scooter, I don't know what happen to this engine. Only an oil can make my engine turn to this? The RPM increased rapidly, but very smooth. I never get such a experience like this. I watch the RPM meter, and I can't stand it watching the neddle movement. I'm so excited.

The last one that make me currious until now, is the clutch. My scooter clutch is a dry type. With the last one, my scooter isn't run smoothly. There is some vibration just before the scooter is moving. But now, the vibration on the clutch almost gone. What happen? I don't know the answer, my assumption is, it related to the RPM that increased rapidly, so that make the torsion increased too. Torsion increased make my clutch spin faster, and the clutch open correctly on the right RPM.

Thats all today test. I should wait a little longer to test this oil endurance. Amsoil claim that the NOACK is 6.44%, this number indicate the weight loss. The number is very low, so my assumption is the oil loss is very minimum, and I don't have to check the oil level twice a month. Or may be I should? Oh, I don't wanna take the risk, I will check it based on my regular schedule and measure the weight loss every 2000 km.
