when u mention semi is worst then fully, how bad it was?
mine use fully synthetic shell helix from start.. pickup is slower when in auto mode, try manual mode to accelerate better.. quick response in changing gear too..
ok i am not sure when i get the new car (what oil they r using, i assume its semi syn)
therefore
New car - semi syn ( i assumed)
1k mileage 1st service (i change to full syn 10-40w shell helix la)
performance okay, been driving it for a few trips kl-johor + 1 trip to KL-Alor Setar
Engine well response, gear also smooth, petrol saver

depending on how fast u drive!
7.5k mileage 2nd service (i choose back semi syn, becoz this 2 months not many outstation trips)
i. feel sluggish compare to full syn after i drive for a few days only (mayb placebo effect i dunno la, i juz feel it that way)
ii. Car shaken due to the gear drop from 2 -> 1 when u let ur car speed slow down from 30kmh -> 10kmh, i am saying slow down ar, i didnt apply brake, and i can feel the SHAKE when the gear shift to lower gear WTF?
yes i know there will be a slight shake when the gear switch back to 1st/2nd gear, but this time i feel stronger shake la.
iii climb hill feel lesser responsive, as i always need to climb a hill to reach my home, i need to adjust to manual shift and downshift it back to lift the speed to 50kmh; whereby previous i dont need to apply manual shift when i am using full syn, i juz need to apply my foot to adjust the pedal...
iv again, maybe placebo effect i hear my engine roaring louder in semi syn..
so i might wanna change the semi sym oil after i finish my johor trip this weekend.
