EJ20H-TT Posted January 15, 2004 Author Share Posted January 15, 2004 [quote name='MSB']Fuel in Japan currently costs about 115yen per litre of 100 Ron "super" which is the recommended fuel for my Legacy GT Spec B. Does anyone know where on the web there is info re using lower grade fuel, as I'll probably take the car to the UK or Oz when we leave Japan[/quote] Not that i know of but.... Here in NZ we have the JDM GT spec B and it runs on 98/96 Octane here no trouble. If u read through this these threads u will see GTmy04 runs his GT in Aussie on 98/96 as well. However the aussie GT has been slightly detuned though. They are probably too conservative. Link to comment Share on other sites More sharing options...
Tide Posted January 15, 2004 Share Posted January 15, 2004 It's amazing to me how much fuel costs anywhere other than the US. Here we pay about 1.80 per gallon for premium. The same in the UK would run us about 4.00. Heck I can get 100 octane (race gas) for $4.50 a gallon here. Ah, the oil dependent US. Link to comment Share on other sites More sharing options...
Skylab Posted January 15, 2004 Share Posted January 15, 2004 Running higher octane in a computer controlled car without being able to bump up the timing would be a waste of money. Link to comment Share on other sites More sharing options...

If I only ever ran 100 Octane in it, the computer would learn over time and adjust. Waste of money, problably so. Would I be fooked if I went back to 91. Absolutely. If I ran a XEDE I could hold 2 maps though. Seems the best option to get the most out of a California car. Link to comment Share on other sites More sharing options...
EJ20H-TT Posted January 15, 2004 Author Share Posted January 15, 2004 Knew a guy who ran his TT GTB on 98 octane. He accidently put in 91 octane - car pinged like mad on acceleration - but very quickly changed the timming to run fine - obviously lacking in power tho. When he put 98 back in - it took a little while but the ecu learnt and advanced the engine to the old maps Link to comment Share on other sites More sharing options...
MSB Posted January 16, 2004 Share Posted January 16, 2004 [quote name='PPower']So that's about $4.11/gallon at 106yen/dollar & 3.79 liters/gallon.

MT or AT?[/quote] It is an AT, and I'll try and post some pics, after I've given it a wash :oops: Link to comment Share on other sites More sharing options...
AMT4SWA Posted January 16, 2004 Share Posted January 16, 2004 Tide...the fuel cost is the same for everyone WHOLESALE from the oil companies, it is the countries varying TAX levels on fuels that makes most of the difference. Link to comment Share on other sites More sharing options...
PPower Posted January 16, 2004 Share Posted January 16, 2004 ^yep. For one thing, raising fuel taxes can act as a way to encourage lower consumption and higher fuel economy from auto manufacturers. This is the same thing with car prices for the most part like the GTO selling for less than the Monaro. It has to be from charges bein levied on cars sold in Australia. As I said elsewhere, Costa Rica had 100% import duties/taxes on all cars. This was originally done to promote public transportation and limit people from buying cars. All it did was promote too many piece of crap cars on the road. Because of some trade treaty with Korea set years before, there were much lower taxes on Korean imports=cars (for Korea to buy CR coffee/bananas mainly). So there were boatloads of Hyundai, Kia, Daewoo, and Ssang Yong. It also acted as a usuary tax in a country where proper and fair income tax collection may not be the best. If you can afford the 360 Modena convertible a dude drove around, he paid the taxes and probably had evaded taxes from other sources that more than made up for it. Remember that if you pay 30% taxes, you have to earn almost $43,000 for a $30,000 car. Link to comment Share on other sites More sharing options...

shelltox Posted January 19, 2004 Share Posted January 19, 2004 I think it would be good to be able to do a couple of tanks on RON96 and then switch to RON98 to sort of clean out the engine so your engine stays clean most of the time. I know in my car (non turbo) I run a couple of tanks or so on regular and then do a higher octane to clean out the tank couple with a bottle of fuel injector cleaner when I top up with the higher octane fuel, the performance is much better and there is less pinging or lag. Acceleration is much smoother as well. Also on the subject note, I was thinking would perhaps an Octane booster like the Octane104+ (I think) help the engine to attain higher octane, instead of using the ideal 100LL which is not available in most places, I'm sure the engine would be as sweet as consuming 100LL. This could be a less expensive alternate. Link to comment Share on other sites More sharing options...
PPower Posted January 19, 2004 Share Posted January 19, 2004 HUH? Where did you get that running low octane and then higher octane will clean out an engine? As for octane boosters, I think you'd better research that a little bit. The do not work like you are thinking it does. Splashing in some race gas is much cheaper.

EJ20H-TT Posted February 14, 2004 Author Share Posted February 14, 2004 I think i have found the Japanese fuel specs 100 octane (ron) 88 octane (mon) So that comes to 94 (ron+mon)/2 So perhap US fuel isn't so bad after all ? Best i can get is 98 ron & 87 mon. Link to comment Share on other sites More sharing options...
THAWA Posted February 14, 2004 Share Posted February 14, 2004 There's 91-92 around here at like $1.70/gal Dunno for sure, I don't pay much attention to it. Link to comment Share on other sites More sharing options...
SUBE555 Posted February 14, 2004 Share Posted February 14, 2004 You can get 87, 89, 91, 92, 93, and 94 all at one of the local stations a few miles from me. Link to comment Share on other sites More sharing options...
