ya.. 91 octane and a bottle of octane booster. oh well nice car

ive seen the guy around a lot.....I think 91/92 is what it is rated for....if it was rated for 94..where the hell would you buy gas in the states...lol.

My favorite car... in the color I want :drool

Yeah its made to run 91 premium from the factory for North America, so don't really need to use 94 but I personally would If I had a car like that.

Could be a leased car? I have a friend with a new Porsche 911 and he puts in 89 lol.

:facepalm:

If even supercars are designed to use 91. What is 94 for then?

Performance boosts? No wait wouldn't they use 100 race fuel then?

yeah race gas^, but that's only available at the track and limited places.


here's a good read I got from a quick google search:

Quote:

The Low-Down on High Octane Gasoline Are you tempted to buy a high-octane gasoline for your car because you want to improve its performance? If so, take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner’s manual. The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars. Unless your engine is knocking, buying higher octane gasoline is a waste of money, too. Premium gas costs .15 to .20 cents per gallon more than regular. That can add up to $100.00 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher-octane gas than they need. What Are Octane Ratings? Octane ratings measure a gasoline’s ability to resist engine knock, a rattling or pinging sound that results from premature ignition of the compressed fuel-air mixture in one or more cylinders. Most gas stations offer three octane grades: regular, usually 87 octane, mid-grade, usually 89 octane and premium, usually 92 or 93. The ratings must be posted on bright yellow stickers on each gasoline pump. What’s The Right Octane Level For Your Car? Check your owner’s manual to determine the right octane level for your car. Regular octane is recommended for most cars. However, some cars with high compression engines, like sports cars and certain luxury cars, need mid-grade or premium gasoline to prevent knock. How Can You Tell If You’re Using The Right Octane Level? Listen to your car’s engine. If it doesn’t knock when you use the recommended octane, you’re using the right grade of gasoline. Will Higher Octane Gasoline Clean Your Engine Better? As a rule, high-octane gasoline does not outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car’s engine. In fact, the U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car. Should You Ever Switch To A Higher Octane Gasoline? A few car engines may knock or ping — even if you use the recommended octane. If this happens, try switching to the next highest octane grade. In many cases, switching to the mid-grade or premium-grade gasoline will eliminate the knock. If the knocking or pinging continues after one or two fill-ups, you may need a tune-up or some other repair. After that work is done, go back to the lowest octane grade at which your engine runs without knocking. Is Knocking Harmful? Occasional light knocking or pinging won’t harm your engine, and doesn’t indicate a need for higher octane. But don’t ignore severe knocking. A heavy or persistent knock can lead to engine damage. Is All "Premium" Or "Regular" Gasoline The Same? The octane rating of gasoline marked "premium" or "regular" is not consistent across the country. One state may require a minimum octane rating of 92 for all premium gasoline, while another may allow 90 octane to be called premium. To make sure you know what you’re buying, check the octane rating on the yellow sticker on the gas pump instead of relying on the name "premium" or "regular." .

Yeah but your also the kinda numbskull that would run 94 octane on a non turbo supra.

No need for 94 in a NA Supra like you said...Even the turbo's are recommended 91. so +1

Ya... recommended 91 in North America (USDM Supra's). He forgot to mention mine was JDM.

Domestic Cars (rhd imports), their premium fuel is 98 and 100 RON...
From what I've read the conversion to our fuel readings is exactly 95.8 Octane (for 100 ron).

I only used 94 becuase it got better fuel economy vs 91. For my TT I'll see which fuel is better.

I'll also be using 94 when my Supra goes under the knife lol.

03 CL600's owners manual says 93+ octane REQUIRED... none for recommendation, whereas CL55 and CL500 is 91+ required...

For people with Tercels running aftermarket exhausts and twin electric turbo's. :fullofwin:

Ferrari recommends Shell gas even for the Enzo and Shell only carries 91 oct.

No factory car needs 94 oct. You can't get 94 in California and they have a ton of exotics down there.

putting 94 in your car is a waste unless it's been tuned on a dyno to run 94 oct.

^ the factory recommends 94 oct for my GT3, they state it can run on 91, but it has been tuned for 94 oct.

isn't the CL600 twin turbocharged V12?

yes.:) one of the fastest cars produced from factory....I always wanted one...:fullofwin:

yep, and here's the digital version's page

great advice
