Best choice is 0W20 oil, coxmotorparts sells Honda, Castrol and Mobil proper lubricants for your Jazz.
Many thanks jazzaro.
Editing to say I have just had a look at the coxmotorparts website you linked to and I am sure it will come in handy for parts one day, thanks again.
Regarding the engine oil, they sell genuine Honda OW20 type 2 synthetic engine oil.
I see they also sell Castrol Magnatec OW30 stop start C2 fully synthetic.
Is that for the idle stop feature? I try to remember to press the button to turn that off.
You're welcome.
Acea C2 0w30 oil is for the 1.6 diesel engine of Civics and Crv with particulate filter. C_x specification is for engines with particulate filters, oils have a low sulphur composition to avoid filter clogging: engines without particulate filters can use oils with sulphur and this helps engine lubrication, so if possible avoid Acea Cxx oils.
Castrol 0w20, and the Honda Type2 are both good oils for your engine, as 0w20 they are good for star and stop mode.
The general law is the following: apart from specific engines with a user manual writing "DO NOT USE THESE OILS : .....", engines WITH particulate filters (petrol and diesel, so GPF and DPF) MUST use ACEA Cx oils with low saps specifications, other oils will permanently clogge and damage the particulate filter.
Engines WITHOUT particulate filters can use ACEA Ax, Bx and Cx oils but it's better to avoid ACEA Cx, since the low saps formulation is not the best for engine lubrication.
About a 0W20 oil and the general belief that it's too thin and light for our engine... Consider that this viscosity is used for modern turbo supercharged engines like the 1.5 Civic petrol engine, 180hp, so no worry about our 102 hp naturally aspirated 1.3 16v.
