Petronas has 4 types of oil: Fully synthetic has got 2 types and 1 each for semi and mineral.

yup that 4 for open markets... for kia SC they're using 2 types only...
5w-30 4L for fully syn... for mineral forgot the specs...
my next change want to try MoS2 Leichtlauf - 10W30 - 4L

Looks like naza has a bulk purchase wif petronas. I know the Pugs are also using Petronas. Not sure bout chevy though.

Engine oil also play an important role in performance besides upkeep. Honestly i dont think petronas oil is tt good based on my butt feel. Petrol yes. Oil no. Ok onli.But then again its a mid range brand.

Dyno has shown tt usage of differrent grade/quality oil (same viscosity) can improve +1 to 1.5 whp based on same car.

Added on February 8, 2012, 6:14 pmHow flexible are the sc in terms of allowing customers to bring in own oil? I assume your car is still under warranty?

I can recommend a few brands tt is really worthwhile trying out n it wont disappoint based on my experience. Motul n Torco. Both r really good.

yup & the bad things they didn't allow us to bring our own engine oil...

Aiksei! How i wish they would allow. No offence to petronas but there is much better oil out there. Actually all sc are like tt.

Even if they insist on Petronas, i can easily get cheaper Petronas engine oil outside.

SC prices we all know is marked up or how to pay their staff salary.

Juz wished they hav a guideline where better oil can be brought in wif a small surcharge. I think thats fair.

simple, now they offer long long warranty they dont want customer doing things on their own then claim warranty.

can be those cheapskate buy cheapest oil or fake oil then when something break blame SC should know what is fake what is not, not enough knowledge, bla bla bla want to claim new car etc.

stupid people a lot outside

But i think i read somewhere in the manual stated that change engine oil + filter will not void warranty as long u follow the months/mileage...

Well, it kinda depends on the type of CVT used. The simpler design found in the City had a max hp rating of around 120PS if I remember correctly. Can't remember the max torque rating though.

The one in the Nissan I believe is called a toroidal CVT or something like that, can't remember. It's quite different than the one used in the Honda, although I believe both are sourced from Jatco.

Being a relatively alien technology to workshops, with hardly any used parts around, repairs can be quite costly. That said, even two years ago I could find tranny rebuilders advertising CVT rebuilds for around RM1,500 (as opposed to between RM400-1000 for regular ATs), so maybe they've learnt how to fix them cheaply.

There's hardly any downside to a CVT system apart from the rubberband effect between throttle input and response, which is supposedly slightly slower than a regular autobox and definitely slower than a DSG.

I can't say much about other CVTs, but on my previous Honda City iDSI, I have had no problems whatsoever with my gearbox. Just had to maintain a regular drain interval of 30,000km, that's about it. I clocked 180,000km on that car, driving it for 5 years before selling it to a used car dealer who tested my CVT to make sure it was ok lol... Eventually you will have to change the dry clutch within the CVT.

The feeling of a CVT for regular cruising can best be described as smooth and carefree. The only thing I didn't like about the implementation on the City was it lacked a ratio lockup for highway runs. I've read that most CVTs today have some form of ratio lockup (like a conventional AT's torque converter lockup clutch) to keep revs at a minimum on highways. Without a lockup, my FC for 100% city driving and 100% highway was pretty much the same, consistently around 6.5l/100km on RON 95.

Added on February 9, 2012, 1:24 amI don't think that's right. Max torque is always reached before max hp. I think you mean max hp at 6,500rpm right?

the biggest problem is the feel, cvt's with torque converters feel like driving a rubberband, you rev and wait and wait and wait then it moves.

once it moves you think you;re driving a scooter, because the engine stays at the same revs constantly buzzing and droning away.

Hi Epo,
Have u heard of hyundai oil bank fully synthetic oil?
Actually my last service before CNY was using that oil. Slightly cheaper than using Petronas 5W 30S.
According to the SC, it is lighter and better performance. (Say onli but dunno how true)
It is available in MPV car service at selayang SC.

I m not use to driving a cvt. Dont own one but have driven one. I notice it doesnt favour heavy footed fellas. Its tt eerie feeling when you floor the pedal and the revs hold at a hi rpm. As if its gonna blow!

Agree with you on that... used to drive a Lancer GT for the past 4 years and the rubberband effect is very pronounce.
I ended up changing to lightweight crank pulley and installing throttle controller to try to get rid of the feeling.
Now driving a normal 6-speedo Sportage and feels the pickup is damn sluggish....

nope... maybe certain2 SC je yg use kot...

WWJ number plate has started Friday after lunch!

Thats really fast! I remember WWH being issued last Tue or Thu. Within 10 days per alphabet.

waiting for WWW...

you know about that too? thats one rare gearbox, can tahan high torque i think found on the previous skyline sedan, these should be before the Xtronic ones came out.

as for the max torque, it;'s usually at where the torque curve bisects the power curve..
yeah there is no max torque at max power.. LOL..
