Testing Shell Advance 10W-40

Wednesday, August 29, 2007, I buy a brand new oil, that is Shell Advance VSX 10W-40. I am so curious about this oil, because it is cheaper a bit than the oil that I used before.

At 8.20 pm, I drain the oil and fill it with the new one.

Thursday, August 30, 2007, I test it on the way to the office. I turn on the engine and wait until it ready.

I run my scooter with my beloved wife. I dislike it power and torque, because it is not like before. The power has drop, I don't know the exact number, but I can feel it. While I'm riding my scooter, I can feel that the engine too hard to operate, may be if I remove some milliliter of the oil it will help out.

At 4.00 pm, I go to the parking line and see the oil gauge. Hem, I think I should do it right away to decrease the oil level. But I don't brought any tools right now, what should I do? Don't tell me that I should go home and do it on the garage. But I don't have any choice didn't I?

At 8.40 pm, in the garage, I decrease some amount of the oil. I don't like this way, because it riskying the engine life.

Friday, August 31, 2007, I test it again. This time the engine power is not like before, it increase. But still, I don't like it, I expect more than this. Should I decrease it again?

Readjusting The Air Mixture

Monday, August 6, 2007, I open the baggage just to adjust the idle screw. But I wonder what if I adjust the air screw again.

First, I turn the idle screw to clockwise until the RPM high enough. Now I turn the air screw clockwise until reaching the end, and turn it counter-clockwise until it get the highest RPM.

Second, I adjust the idle scew until 1700 RPM on idle.

Jobs Done. The test is running my scooter to the office. I know this is not a good idea, but I don't have any choice.

After my wife sit properly on the seat, I run the scooter to the road. The path is usual as yesterday. When I open the throttle, I feel something different with the scooter, the power is amazing. I think this is the best set of carburetor air mixture, I don't know why. May be this morning I can feel and hear the engine sound clearly enough, or may be my mind too.

From now on, riding become so much fun.

Testing Shell 10W-40

Wednesday, August 1, 2007, I go to the workshop for servicing my scooter. I want to test this Shell Helix Plus. I pick Shell 10W-40 API SL.

I want to test it compare to the older one. So I don't want any changes on my scooter setting. Even on the valve clearance or anything. I want the test as accurate as possible.

After finished, I'm leaving the workshop to test the result. Here it is the result:

- Sound
I run my scooter below 40kmh for a couple of hundred meter just to make sure that the oil has circulated inside the engine. Now, lets hear the engine sound. The traffic condition is very suited for this test, yes it is very light traffic. So I can hear my engine sound very well. My engine sound is very quiet. I love it very much.

If this sound keep like this until the time I change it, then I will use it again.

- Vibration
While I'm testing the sound, I also test the vibration. I run my scooter in low, medium and high RPM until 9000. In any RPM, my scooter vibration is better than before. This time my scooter is a lot more smoother.

- Power
I run my scooter as usual. The power has increased very little, you can not feel it if you aren't feel it deeply. I can get to 60kmh without a notice. I think this is correlation with the vibration that has decreased. I can get through the heavy traffic lightly without any trouble.

- Top Speed
I haven't test it yet, may be next time. I can only reach 80kmh, I can not go faster because of the traffic.

Overal, this oil is good, better than before. The smell is good too. May be I should test it again before I change it, whether the sound, vibration and any other test items are decresed and how much does it decresed?
