Used-tried it ?

any review ? better performance ?any much difference from shell 98 oktan ?



I use 98 Oktan for new 2005 C SC .100 oktan is problem for it ?

Not sure where you are, but V Power here is 93 octane, and, according to the Shell website, V Power is 90 to 93 octane, depending upon what part of the country you are in.

gaiex

Yeah, its good, you can feel some diference
Are you in Europe or what?

Shell V-power 100oktan is comon here...

ismeto

where shell 90-93 I do not know

here Shell only sell 95 and new V-racing 100 oktan

They say in teir catalog it is %5 speed than 95 oktan..

ismeto

exactly brand name

V-Power Racing Ferrari...

(I do not understand why they use Ferrari name... they say they developed for Ferrari with Ferrari in the Formula 1 )

I think it 100 octane wouldn't do much over 98. Especially if you have stock ECU. I have a feeling that with stock ECU, the optimum octane is 94.. at least in the US.

If they developed the gas specifically for the Formula 1 Ferrari, that's why they used the Ferrari name. It was probably a joint project that would give Ferrari credits in promoting the gasoline.

As for using it in your w203, there's not really any need to use that high an octane unless you are running with heavy mods on your car. The 95 octane they offer in Turkey should be fine.

No matter what, my personal experience with Shell w/ V-power has been excellent. The car just runs better with that gasoline vs. any other.

I would onyl recommend using 100 octane fuel with jap cars

unless you have an aftermarket ecu to change the map

okay guy's this is what i heard about V-power from a worker that works in my local gas station. he was telling me that Shell has 5 cleaning agents that help keep ur motor running nice also it has busters like (STP, or any other Octane buster) that is cool. that's why i use SHELL

I used BP Ultimate (93?) and Sunoco's Ultra 64 (94?)

Theres no much of a difference, its just that BP gives off a louder sound and sunoco is a lil more quiet.... but like said above, with the stock ECU, theres really no need for a higher octane

yeah by the way, I remember the dealer telling me not to put over Regular in the 230k, said its not "good" for the engine...

I just threw in Ultimate in the 230k, 1st to 2nd gear jerks like crazzzzyyyy

I asked few Authoritised Mercedes Service Dialer Today they said to me best is 95 octane is enough 1.8 lt engine and one dialer said 100 octane can damage engine .I bought some to try 100 and I will add on it with 95

I am returning 95 octane Shell or 94 octane BP Ultimate.

That's weird; Here in Norway it's marketed as 'V-power' only (no mention of octane - but in Germany the name 'V-power' is in the background, their main marketing trick there is '100 Octane'... So, guessing it's different for each country?

gaiex

One question here:
What damage could a rich petrol (100) do to the engine?

advans

I think the damage being the compression ratio that the 100octane can screw up

Here in Chicago they sell V-Power, which is their premium grade of gasoline. The pump is marked at 93 octane.

I have religiously used BP Amoco at 91 octane, but tried the V-Power for the first time this summer. Definite difference,more than just subtle. I have a 6-speed, and notice much more off-the-line power in both 1st and 2nd gear. The engine just seems to run better, more responsive.

Higher octane prevents pinging/knocking, which means prevents fuel mixture from exploding due to compression before the spark. i.e. before the engine is ready.

So the more compression, the higher octane needed.

The engine is designed (and the ECU programmed) to work for 91 octane in the US (because there are states where you can't find more than 91). Higher than 91 doesn't hurt. But you don't gain anything either.
Unless you can increase your compression to take advantage of it. (which you can't on most cars).

Here is what I don't understand. Octane used should be user selectable. This way, if you put higher octane, you could use a different program that would create more compression, thus more power. And if you want to save money and use regular (87 octane), you could use a program to lower the compression and prevent damage to the engine (and lower hp).
Maybe the car should ask you what fuel you put every time you put gas.

I don't know why it doesn't exist...

Sunman told me that he "might" be able to change fuel settings with the star diagnose. But I don't want my car to be the guinea pig... It would be nice because the car is set to 91 octane and in Texas we have 93.

One more thing, I know that octane is computed differently in Europe. So you can't compare US and Europe octane numbers directly. In the US there is a sticker on the pump that tells you what method they use to compute the octane number.

revstriker

It doesn't exist because most people do not understand how this works. Also, what if someone put a low Octane level in their car, but then selected the highest octane level, and ended up doing damage to their engine?

If the manufactures were to allow you to make these changes on your own, then I bet there would be more claims against them for problems, and at the very least, they would end up with a lower customer satisfaction rating.

Today, you cannot make these changes on your own. If you were to find a way to do so, then the manufacture could always argue that your warranty is voided because you changed the factory settings.

Yup, what bnzct says. You can not 'screw up' your engine by running a higher octane (unless it has lead in it - which could do bad things to an engine designed for unleaded). More octane will let you run more boost (i.e. higher compression) without detonation occurring (i.e. knocking/pinging leading to burning holes in your pistons). If your car is set up for 91 octane, anything more than that is a waste. You might feel a difference between, say, 89 octane, where engine management has to retard the timing, but engine management (i.e. computer) won't raise boost for you if using higher octane fuel. Some folks who modify their turbocharged cars will add a manual boost controller/boost guages so they can turn up the boost if using better gas (of course there's always a risk of turning up the boost too much...). Also correct on the different octane ratings in Europe. Here in the states we use (R+M)/2, where as across the pond they use just R (or M?). Hope this helps.

Great Answer.. took the words out of my brain\!

I ask to Sportcoupe owner same question


What do you use for your Sportcoupe ? octane rate please . and brand name Shell...BP. etc.


US EU or any world

Lead was the anti-knock agent in the past.
I THINK it's still OK for the engine. The problem is that it will kill the catalytic converter. The car will still work, it will just pollute like an old car without catalytic converter.
I don't think you can find leaded gasoline anyway.
