Mr Italy! Posted April 21, 2006 Share Posted April 21, 2006 Its the octane in the fuel. Our cars are tuned for high octane fuels. Regular fuel in japan has a higher octane then the premium fuel we have in australia. You use shit fuel, you get engine knock, which is not good. Do a search for Ping, Knock, Detonation, Pre-Ignition, rich and retard - you'll start to understand why you need to use premium fuel.

Leewah Posted April 21, 2006 Share Posted April 21, 2006 Tell him you have a turbo and he doesn't. Go into the jargon about how advanced your timing is and the Japs run their cars on 103RON etc, etc, etc. Just confuse the guy and he'll give up. Being a 130k 5 series and post 93, I'm assuming he's driving a 530i and from all accounts, his car should be using premium unleaded too.

ebola Posted April 21, 2006 Share Posted April 21, 2006 I use premium or an ethanol blend fuel. If I don't, I get (audible) pinging. If you don't mind the risk, you could duplicate the experiment. Boring old ULP, 2nd gear and full throttle to (almost) redline. Um, offstreet or pulling onto a freeway for legalitys sake. Mr Italy! is right. just tell him your car will ping, and then tell him how much a new engine (plus labour) will cost. Its like insurance, only alot more fun.

_8OO5TED_ Posted April 21, 2006 Share Posted April 21, 2006 yes it loved it, just proves the difference and reasoning why U98 is the preferred choice over Regular Unleaded.

Exactly... LOL tell your dad he SHOULD be using premium unleaded as well. Besides, it isn't a big difference at the end of the day. Saving those few cents isn't going to make your rich, nor is spending those few cents going to make you poor. That's my moto.

RB30-POWER Posted April 21, 2006 Share Posted April 21, 2006 Not to mention the extra detergents and stuff in the premium fuels, goes along way to keeping your fuel injection system nice and clean. Your Skyline has active knock sensing that will retard the timing by x amount however, it isnt designed to pull timing enough to cater for a drop in ron from 100 to 91. Besides, once the system even your old mans pulls the timing etc, your fuel consumption and power will go to the shitter. So he may not end up saving 4c/L after all.

kralster Posted April 21, 2006 Share Posted April 21, 2006 Just lately i've been thinking about the whole ULP Vs PULP debate and i'm starting to wonder if it's worth it. Ever since i've had my car it's had only BP Ultimate which is 10 cents a litre dearer than regular ULP. And i'm wondering if it makes and difference what so ever. The compliance manual that came with my car says 91 octance. And just the other week i had this guy who was probably around 50 years old come in the most mint series 2 r33 i've ever seen come and and put regular ulp in it. And when i asked him about his car he said he was an importer and had just bought it back from japan along with a couple of R34 GTR's. He said he runs the GTR's on PULP but he reackons the GTST are fine on ULP.

AzzurrA Posted April 21, 2006 Share Posted April 21, 2006 yeah, he runs it on ULP because he's an IMPORTER and he DOESN'T GIVE A CRAP about what happens to the cars, as they're not his for very long, lol.. as for your dad, well, he should be using PULP in his cars as well, as thats what BMW Recommend. He could possibly be voiding his warranty (though, by the sounds of it, that ran out a while back, if its a 93 model), as BMW Recommend their customers use PULP Link to comment https://www.sau.com.au/forums/topic/114386-premium-vs-unleaded/#findComment-2109271 Share on other sites More sharing options...
chrissso Posted April 21, 2006 Share Posted April 21, 2006 There's a sticker underneath my hood that says use equal to or greater than 95. (93 33 det) However, I' not sure if this was put there during complience or factory. It also says that the ignition timing should be 10 degrees- I thought that it is suposed to be 15. Regardless, all jap cars are suited (timing-ignition maps) to jap fuel, and should be run on 95 or above. I have seen countless threads where people put better fuel in the tank on the dyno and get better results, and less knock.

MANWHORE Posted April 21, 2006 Share Posted April 21, 2006 Why bother convince your dad? He's obviously an idiot. I guess a common problem with people when they are young is they look up to their dads. As I grew up, I realised how stupid he was and how it was pointless trying to keep him happy. How old are you?

kralster Posted April 22, 2006 Share Posted April 22, 2006 Thats a bit harsh, my dad reackons i should be riding my pushbike to work instead of driving cos of the cost of fuel, doesn't mean he's stupid. You junkbroad minded person. Sounds like you came from a very unloving family. Also this imported dude said this new car was his new daily driver. And that sticker under your hood is a compliance sticker. Your car should have them in a few places for things like service intervals, tyre sizes and pressures etc, etc. Mine says 91 RON and thats on a R34.

morgsj50 Posted April 22, 2006 Share Posted April 22, 2006 i think everyone is a little shitty with petrol prices... but the difference between ULP and PULP is less than $10 a tank... it's hardly gonna break the bank... and my theory is if u want feul economy, by a daewoo or something equaly girly, if u want performance, you gotta pay the price...

TheMikeC Posted April 22, 2006 Share Posted April 22, 2006 I'd tell your dad he's paying for repairs if ULP breaks your car, if he doesn't agree then say fine PULP it is then!
