Hi
While looking for Castrol oil recommended for my Jazz 2018 at
https://www.castrol.com/en_gb/united-kingdom/home/car-engine-oil-and-fluids/motor-oil-and-fluids-finder.html
There are two 1.5 petrol, 2018, Jazz models listed
1.5 i-vtec (PF) ACEA C3
and
1.5 i-vtec ACEA A5/B5
My jazz has catalytic converter that is for sure.
Does it make it PF?
Thanks
-
Refer to your owners manual, the info will be in there.
-
Manual recommended Honda oil ;)
If not available use ACEA A5 /B5
Question is why Castrol recommends ACEA C3 for my 1.5 i-vtec if it has PF?
As of my understanding C3 is there to prolong catalytic converter life but A5 is supposedly good for molybdenum ciated bearing or something like that.
Would love to understand more about it.
Thanks

The recommended oil for a UK GK5 1.5 Sport is 0w20 fully synthetic

SAE 0W20 is the viscosity grade, then you must consider also oil specifications (API, ACEA, ...). ACEA Ax oils are formulated for gasoline engines, ACEA Bx oils for diesel engines while ACEA Cx oils are specific for engines with particulate filter, since their ash does not permanently clogg the filter. So engines with particulate filter, gasoline or diesel doesn'matter, MUST USE ACEA Cx lubricants.

The engine of alla 1.5 GK Honda Jazz have the particulate filter, so you must use ACEA C3 oil.
Other countries such as USA and Australia have 1.5 without particulate filter, so they can use ACEA A5/B5 oils.
The 1.3 engine does not have particulate filter.

That is exactly what I concluded ... I just wasn't sure if catalytic converter is actually same thing as particulate filter.
I was checking european user manual (Jazz Dynamic 1.5 i-vtec) and for
2018 it says ACEA A5/B5
For 2019 it says C3
I think that is because from 2018 PF was mandatory on all petrol cars in EU

That is not in question, there are full synthetic 0w20 oils with different set of tests for standard as :
Castrol Edge 0W-20 V A5/B5
Castrol Edge 0W-20 C5
Castrol Edge 0W-20 LL IV FE
Castrol EDGE Professional H 0W-20(for Honda) API SN
and more only from Castrol...

I stand corrected, I have just had a peek at my oil filler cap and C2 is stamped on it which means it has a PF, my car is a late 2018 manufactured car registered 27/02/2019.
Here is the relevant page from my OM

Great staff, that explains everything.
Sometime during 2018 Jazz got PF probably in means of different filter package inside catalytic converter on exhaust line.
Attached is mine oil cap image and as per your kindly provided OM page mine car is without PF and therefore needs A5/B5 ACEA approved OIL.
For viscosity I will stay with 0W-20 over this winter and swap to either 0W-30 or even 5W-30 for summer, as air temperature where I live can go up to 40celsius.
Thanks for input, btw, what engine type you have? Mine is L15B3.

NONONO
GK3s do not have particulate filter, they all have port injection so they don't need it.
EU GK5s have direct fuel injection so they HAVE particulate filter, they need it due to EURO6 emission regulations.

That’s why I corrected myself. The OP was referring to the GK5, mine has a PF and the OP’s doesn’t.

No.
Catalytic converter is a "chemical device" where some type of exaust gas are modified, CO -> CO2, NOx -> becomes N2 and O2, HCx -> H20 and CO2, birefly this device tries to complete the combustion process giving no toxic or polluting matters. There is a sort of honeycomb, platinum, palladium and rhodium internally plated that promotes these reactions when the hot gas just touches the walls of the honeycomb.
The particulate filter is different, it's a filter stopping big pieces of particulate made by not fully burned gasoline or diesel. Then pieces are burned, reducing their size untile they can pass through the filter.
Sometimes we can find PF+Kat in the same assembly, placed close to exaust valves since the PF will work better if gases are hot, so it's not easy to understand if the car has PF or not just having a look under the bonnet. Anyway, EUDM GK5 Jazzs HAVE the PF.

Strange things, mine is Dynamic 2018, German version, euro 6 norm, without PF as per recommended oil(ACEA A5) and oil cap as from above image... uhhhh

Thanks for proper explanation!
I am still not sure if mine Jazz have it or not.
Coc document states euro norm 6 and some 133g/km average.
Would it be possible to check with OBD2 scanning?

Here is OBD scanner screenshot.
I have only found catalyst temperature...

the local Honda dealer uses Castrol Edge 0W 20 , the Honda version.
bought some top up from Opie Oils as the dealer only buys in bulk.
the full spec. for those that understand it
ACEA C5
API SP
ILSAC
GF-6

My local Honda dealership uses Morris Multivis S 0W-20 synthetic oil for our 2018 Jazz sport.

It seems it is not so important at all which certificate 0w20 carries for either Honda dealership or local garages as I read all kind of 0w20 oils are used regardless of certificate.
Take a look at yours oil cap does it say C2 or not as on attached image on previous page in this thread.
I think Honda recommends same oil for either, namely Honda genuine 0W-20
-
Why not get yourself the owners manual for your Jazz, either on line from the dealer or via E Bay .As regards oils any from Opie oils you can chat with them or enter your model spec , always change oil & filter many owners prefer the Honda blue filters . Happy motoring in your Jazz
-
I kept reading endless forums and at the moment I think I will give a try to some 0W-30 A7 oil.
-
Is there a reason why you don't belive it should be C2, as stated in the oil cap?

Gibo's oil cap is not C2

Uhh... Okay! Maybe I misred some of his posts then.

Yes, judging from user manual and oil cap my 1.5 I-VTEC has NO particle filter and therefore it doesn't need low SAPS oil(C2) to prevent clogging on PF.
I spoke to Castrol support and they advise not to use C2 oil but A5/B5.
Still, I am confused as Honda advise to use same oil for models with and without PF, namely Honda Genuine 0w20 oil type 2.0.
As for ACEA A7 oil, it supposed to be better at preserving timing chain and prevent low speed preignition.

From ACEA A7/B7 certified oil I was able only to find 0W-30 and 5W-30.
