farcus:

Learn something every day :)
Wonder if the "regular" is just not as common as 95+, hence the advice I got (and read)...... regardless, our car ran like a dream afterwards :)

Anyone miss the days of having to give your car a "shot" when filling up ? ;)


Japanese petrol stations are just like NZ
Every bank of pumps has Premium / Regular / Diesel
Filled my car up with Regular over the weekend (here in Jpn) @ 156 yen per/L
Anecdotally I have observed here, that just like NZ, more people fill up with regular than Premium


Wikipedia link I mentioned in previous link shows that Japan regualr is 90 RON, anyway to confirm that?

Because same Wikipedia page shows Japan regular is <89 RON and Premium is =<96 RON, so in theory, regular
in Japan could be anything from 90 to 95?

found this on the website of a fuel refinery company.
Basically it says that according to Japanese standard JIS K2202 that Premium (Hi Oc) must meet a standard of 96 octane or higher and that regular gasoline must meet a standard of 89 octane or higher.




edit: looking at the website for ENEOS (largest gasoline retailer in Jpn) it says reg is 89 octane and Hi Oc is 96 octane.

I'm not an expert, but did a bit of research when I purchased my last car and was told it should only run on 98. I had always assumed that higher octane meant more "powerful", but it is really just more stable.

Low octane fuels will prematurely ignite in a high compression engine. While in theory this can cause engine damage, most modern vehicles have pre-knock sensors which compensate for the lower octane fuel by lowering engine performance.

The car will always run best on the octane it was designed and tuned to run on (or higher), but there is no benefit in runner it on a higher octane fuel than it was design and tuned for.

i.e:
Engine designed and tuned for 91 will run optimally 91, 95, or 98
Engine designed and tuned for 95 will run poorly on 91, and optimally on 95 or 98
Engine designed and tuned for 98 will run horribly on 91, poorly on 95, and optimally on 98.

If I'm wrong on any of this please correct me.

Poss a bit out of date, far as I know, Japan domestic engines were/are optimised for 95 unleaded, same for many EU cars - the Lancer (EFI 4G15 engine) was made for 95, even the NZ new models. If in doubt, I'd put 95 in it.
