Whether you use fuel additive or have an on-car clean, and particularly
those who don't use the 98 octane, keep them clean. The wax build-up over time is performance robbing - and you don't notice it beause it's insidiously slow.

Harry - you better get some injector cleaner and use it regularly if you don't want to get blown away again!

SCHIZZLE!

Frizzle - I doubt that there are many oZZies that don't fill up with 98, especially considering that each of the major petrol co are now offering it.

Fess up if you're feeding the Z with anything less than 98!

BTW Harry, I saw a red Z this morning and like you, he thinks red is the fastest colour - he was hammering the throttle in heavy traffic. I was in the sensible 4 door, otherwise I would have obligded him in a little entertainment if the traffic was lighter.

Forgive me lord, for I have sinned!

Just today I needed fuel and couldn't find the normal stuff and ended up using 95 RON. I hope I don't got to ****.

See Jelly, it's true. Red IS the fastest!

As always

98? is that like US-spec gas, because the highest we get here is 93 octane (some stations, 94). Does 98 mean something else or is that an octane rating?

98 is only available at race tracks here. Australia, Japan, and many other countries have high-octane fuel at most stations.

As for injector cleaner, I use 1 bottle of Chevron Techron every 3000 miles will the oil change. I use the bottle good for 20 gallons of gas.

I have also been pondering getting a used set of injectors from someone who has done an upgrade. I would then send them off for balancing and blueprinting (yes, this can be done to injectors). Once I receive them back, I would swap the sets out every 30,000 miles to ensure that I always had a good set going. With blueprint information on each injector, I could even mix the sets to get ones that are truly balanced. Blueprinting and balancing a set through RC Engineering is $250 I think. Of course they bench clean them too. Just a bench cleaning is $80-100 I think.

98 is our RON rating. It is equivalent to your 91MON fuel IIAC. Aussie fuel is very ordinary compared to Japan and even USA!

Thanks.

Actually, I highly recommend the magazine Grassroots Motorsports (www.grassrootsmotorsports.com) to learn about general tech topics. They won't tell you how to do a turbo system on the Z, but they will tell you everything you need to know about turbos in general.

In the last year they covered carbon fiber creation, dry carbon, the above injector information, turbo addons for NA cars, Adam Carrolla's wicked classic Datsun, all road racing circuits, auto cross, corner weighting, camber and caster, etc, etc, etc.

Their website has some great info too.

They built a new Speedway right by my house and it has a racing pump in the front of the station. I believe this is 110 octane. What would happen if I used it?

There's no telling what could happen... the fumes alone might make you do something crazy like respond to a thread that's over 5 years old. Seriously, assuming the it's UNLEADED racing fuel, then absolutely nothing bad will happen. Except of course the acute localized pains that may occur around your wallet.

I remember RoninZ posting something about injector cleaner, summarizing against its use because the main ingredient in injector cleaner is parrafin? I think having them professionally cleaned and flow-matched, then always using the best fuel you can is probably a better investment.

I know the thread has been dug out of the bowels of **** but ill just correct this slightly why we are here LOL

in australia fuel is rated using RON so 98 is our normal best fuel

In the US fuel is rated as (RON+MON)/2 and i beleive there regularly available best fuel is 93

Aussie BP ultimate (probably the most common 98) works out at about 92-93 (R+M)/2

US dont have **** fuels its just rated differently :)

Snobes, most places in the US only have 91! :eek:

When I lived in the Philadelphia area, Sunoco sold 93 there.

I had a full fuel system clean at MRT in Sydney.

I also got my air filter changed at the same time, so although there was an improvement in performance (more responsive) I'd put it down to the Air Filter.
