My car are all using Valvoline product since my last car is using and I feel happy with it.
For this Jazz I had made a service by using Valvoline fully sync cvt/ 5-30w fully sync.
Iet's just hope is just a modern cvt issue jerking :burnout::burnout:
for ATF, its not about the brand but the type of ATF ( Dexron I,II,III, Renaultmatic D3). there are plenty of them and using the wrong type will almost guarantee gb failure.

Anyway driving a cvt is not the same as driving normal torque converte autobox. I havent exp cvt with torque converter so camt comment on that. If u can test another similar jazz then u can see if its a normal situation.

Honda CVT oils if not mistaken is HCF-2 or something like that - not all CVT oils are the same. Nissans one is NS2/NS3 which is not compatible with the Honda CVT oil apparently. So better double check to see if your Valvoline is Honda compatible. I can't remember the type of CVT oil Honda uses and I'm too lazy to google.

Last time when I had a Sylphy, I tried going with the Pennzoil universal gear oil that was supposedly NS2 compatible (Nissan CVT). After using it for a short while I found the gb struggling a lot and felt heavier than normal. Turns out the "fully syn" universal gear oil didn't really work that well in my old Sylphy. End up I dumped the oil and after swapping back to NS2, it worked great again. Expensive lesson to learn.

I saw inside the Valvoline say compatable for Honda (HMMF) need to check Jazz is it compatable or not

Bro CVT is well known for jerking when in traffic jam. It is normal. My friend just bought a new Civic FC and he also say his car will jerking when in traffic jam.He say he complain to SC and SC say is normal for honda CVT.

I'm driving Suprima S, also using CVT. Before this have jerking issue when in traffic jam but since still under warranty, i bring to SC and complain for jerking issue. they help me to do clutch adaption on my car TCU. now no jerking already..
Wow dude tell your friend dont be so satisfied with what they say. Been there before, SC said normal but luckily I found out else where that it's totally not right before it's too late.

The only thing that's normal for a CVT is that rubber band effect, other than that is a potential defect.

Sometimes they say its normal just to get you off their back.

I dunno what is HMMF. But Honda Jazz uses HCF-2 CVT oil. Is that the same as HMMF? I'm too lazy to google atm.
After checking with them they say is the same spec. Now need to check the spark plug also,maybe is missfire due to the sluggish issue.
But thank you for the advice
