Why doesn't it say 98 ron/95 ron if both mean the same thing:rolleyes:

Why use the word Roz to confuse?
 
3 people have so far told you its okay to use 95 ron. Its just Andycupra has told you more than once.

I wouldn't call that scientific proof that its okay to do though.

My mum uses to say, ''if he jumped off a bridge, would you do the same''

Sounds like the case here;)

Yes it will run on 95 ron, thats all you really need to know! If its good for the engine is a total different argument.


When i said this i meant that majority of people are coming back with that 98ron is better for the car.
 
You've also learned that it will give increased MPG so work out your figures and how much it costs to fill a tank and see what the difference is.

If its the sake of £1 or something, wouldn't you want for peace of mind at least that the car was running at its optimum?

Tescos 99 can be bought for 90.9p per litre. What is normal unleaded 87-88?

So thats £1.50-£2 per tank extra, consider your increased mileage and then is it really worth it and the risk by using 95ron?
 
Can I throw in my tuppence worth?Have had my LC(standard) for nearly 3 years now and pretty much used 95 ron a fair percentage of the time,and had no problems whatsoever-averaging about 360-370 to a tank,and I do like to drive quickly but within my limits.I have used some of the higher ron fuels for a while but didnt really notice too much gains-maybe just need to use 98 ron for a bit longer,as I understand the ecu can configure itself between 95 and 98(tho I'm sure some peeps here may correct me here and if you do fair enough,good info to know)
My mate also drives a v6 Mg zs180,running standard which he runs on 95 ron as well with no problems either-before I get flamed I know its a non-turbo engine but surely a good comparison as the power output is similiar?

The details on the fuel cap mean you can use 95 or 98, ron or roz i.e. any combination - 95ron or 95roz or 98ron or 98roz! :D Oh yes!
 
Remeber the majority of people on this forum are nethusists therefore more likely to use the more expensive fuel in their car though choice.

Wgat you need to ask yourself is how many LC are out there not owned by enthusiast and quite happily run on 95 ron

Our lass uses V-power in her LCR as we intend to keep it and therefore want the best for it (cleaning agents and the like) over the next X years.

But if you choose to us 95 fair enough.

Re more MPG, rubbish our lass is still lucky to get more and 22 MPG on V power.

If we are talking performance cars, mine does 0-60 in less than 6 sec and runs happily on 95 ron, any higher and it makes no difference (Elise K-series)
 
K-series does not have a knock sensor though to recognise higher Ron rating so its pointless in that engine.

Depends on what elise you have to its performance, the base model elise versions are slow 60 upwards due to low power output but quick to 60 due to low weight!

Cupra Ross......Just to clarify, after a google search Roz is the German term/equivelant for Ron. I have no idea if the numbers equal the same though? Pretty strange why they dont just put 95 ron though instead of roz. Doesn't make sense to use 2 differing units of measurement.

The elise is slow over 60 due to aerodynamics being suited to handling rather than speed, even the VHPD's don't do much at the top.

Mine will be even slower once the CR gearbox goes on but very quick!

Also just a little point the 1.9 Mi16 was introduced over 15 years ago and had over 165 bhp normaly aspirated (I had a 1993 2.oltr one with 172 following decat and filter upgrade) running on 95 ron so 180 bhp or even 225 is not a great increase/high performace but run of the mill for a hot hatch IMHO.
 
No your right but manufacturers are limited in some respects by the FWD layout, meaning the benchmark hot hatches are all around the 220-240bhp mark.

There's no point in manufacturing a FWD hatch with any more than 240ish bhp in standard trim due to traction and handling problems! It would cost them a hell of a lot to change the layout to RWD/4wd, etc. The S3 and Golf R32 are examples of this but the cost of these new are 25-30k.

The new breed of cars are all safety manufactured aswell which obviously increase weight. Its doubtful you'll get a 240bhp Fwd hatch nowadays that weighs the 800-1000kg that hatches were 10-15yrs ago. They're all around the 1200-1450kg mark.
 
Christ, what a heated debate. Been feeding my beaste nowt but V-Power since Saturday. £70 and counting :/ ffs.

Garage handed me a binder with over £3,000 of fuel receipts.. a cursory glance tells me it's been run on Optimax since day one. Lucky sod who drove it before me had a Star Fuel-card.. company was paying for every single drop, basically. Pfft :<

BTW: Is this car MEANT to drink like a fish around town? I'm really not booting it. I'm being very cautious of revs and speed in an effort to stem the tide of petrol bills.. but omfg, it's costing me a mint in fuel!!!

not really on topic is it lads??

Ive heard they are supposed to be 'heavy' on juice...but then again it all depends what you call heavy!

just think of the extra pounds you'd saved running it on 95ron......:funk:
 
Like I say our lass is lucky to get much over 20mpg.

My thought is if it drinks around town you might as well enjoy it at the same time so have fun getting to the limit

Asa rule of thumb, if you are not getting at least 10 mpg below the oficial figures your not tying hard enough

If your lass is getting 20mpg then there must be a problem. On a 20 mile trip (A road driving) I usually see about 30mpg in my LCR. If I do a 40mile trip down the M56 then I nearly always see 35mpg, I don't drive the car slowly either. I do roughly 300 miles per week and it usually costs me in the region of £40ish quid to fill (from 1/4 tank to full - V-Power only).

Whats quite interesting is that my friend blew the turbo on his LC when it had only done 60k. Could this be due to running it on 95 ron???
 
My LC i can get 31mpg driving at 60-70mph everywhere but usually rough out 22-26! mind you lots of roundabouts here and im not the easiest of drivers!!


Here's something else i found out guys..

I just went and bought some V power from the local shell station, now how does this work???

There are 2 garages in colchester, one which takes you onto the a12 and one onto the a120..

Now the garage that takes you onto the a12 charges you 94.9p per litre, where as the a120 garage charges you only 91.9p per litre, i know its only 3p but it adds up over a month and the two garages are only 1 mile apart???

Im confused!!

I usually pay 91.9p from my local shell in Manchester. Seems pointless paying 88.9p for 95ron. If V power was ever to shoot past the £1 mark then I'd probably have to find an alternative.
 
Always run my LCR on Optimax/V-Power. Have no idea what the previous owner did.

I even run my other halfs Bravo on it! Dunno why it's a 1.2 it's just like I'm lured to the V-Power pump. Good for the pluspoints though!
