95 ron

Technically It should be ok but you won't be getting the most out of the engine. BUT I will say I once ran mine on standard unleaded and will never do it again, just didn't feel as smooth and my MPG dropped.
Yes both 95 and 98,
but the engine has more chance of pulling the timing due to 95 being less tolerant to pre-ignition,
i found running bog standard "copper" plugs had a benefit as the thin plat & iridium plugs fitted as standard don't dissipate heat as quickly, which could be a cause of pre det,
running colder plugs can also help depending if youre mapped.

Mine is standard bar a jetex filter and forge dv. Always run on std fuel as i don't get any premium fuel like vpower or ultimate, and runs perfect, i have no complaints with it. I know i could get an additive but it doesn't seem to need it.
Don't want to hijack the thread, but how much of a difference is there between std fuel, std fuel with an additive, and premium fuel?

95 is the best fuel we get here. Car runs fine, just doesn't pull as hard as it does with a healthy dose of octane booster.
That's with stage 2 by the way. Stock you won't have any issues...

The LCR can be run on 95 RON but the knock sensor will be pulling the timing back all the time. The car is specced for 98 RON, and the manual warns you only to fill with 95 RON if nothing else is available.
Do most cars not reccomend that they run on 98 though? Just the usual kind of arse covering from manufacturers, same with oils, you know the usual we reccomend this stuff.
For what its worth I always fill mine with V-Power, I dont do a lot of miles so I dont grudge the extra few quid at the pump. I dont see much difference in mpg but the engine definately runs a bit smoother and pulls harder on V-Power.
Correct me if Im wrong but if you start using 98 does it not take the ECU a wee while to adjust to the different fuel meaning you dont see the benefits straight away?

On my commute (pre redundancy) I got 32mpg, if I drove normally on vpower. On the one occasion I had to use some Jet 95 Ron, I could not get above 28mpg, no matter how I nursed it.
My liquid gauge says 280bhp on vpower, it was less than 260 on 95 Ron.
As for the ECU, after the Jet 95 Ron, it took just shy of 50 miles on vpower before it returned to normal
In my opinion V Power works out better all round, not sure if mine been remapped emphasises the difference? Either way I've stuck to vpower or Tesco Momentum ever since
Hope that helps mate

As above, I do quite a lot of miles commuting to and from work and have been running on 95 for months, mainly to save a few quid. Couldn't get above 27 mpg no matter how carefully I drove. A couple of weeks ago I tried bp ultimate which is 97 Ron I think. I am also sceptical of manufacturers recommending this and that but I have to say it made a noticeable difference to how my lcr drives. Mpg is more like 29 - 30 and more importantly the car is much smoother and keener to rev. I will not touch anything less than 97 now. It honestly does make a difference IMO and with the higher mpg it almost offsets the higher cost of the fuel, and you can be safe in the knowledge that the engine is happy. Hope that helps you a bit
Since I bought mine I have run it on v-power. I joined the shell drivers club and have racked up 1666 points . You get 1 point per litre. I have just been invited to join the shell v- power club . Ooooooooooooohhhh ha ha. You get 2 points per litre if u join that. I Recieve money off fuel vouchers .not much but it helps and for the sake of the extra few quid at the pump , you pretty much get it back in mpg. Mine ain't an LCR its a 180 LC stage 1. I can honestly say I filled up twice with 95 on motorway and I could not tell difference it but maybe it's different in LCR or I am just not in tune with my car!
most of the time i use 95 ron for the simple fact i dont go past anywhere on my rought to work that has higher ron, but when i do go to the tesco near me and put momentum in, as soon as i pull of the forcourt it feels smoother and mor eager.
ive also tried bp ultimate and thought that was poo, dont have any shells near me either.

If you asking the question you shouldn't be driving a cupra R. Sos to be harsh, but the car doesn't like 95 one bit, and if you gonna be stuck in traffic all the time, then get a diesel surely.

No.From the Leon manual, Section 3 Tips and Maintenance; Filling the Tank:
"General notes
• Unleaded petrol must comply with DIN EN 228 and leaded petrol with DIN 51 600.
• If, in an emergency, the octane rating of the available petrol is lower than that required by the engine, only drive with medium engine speeds and low engine loading. High engine loading with full throttle or high revs can cause engine damage. Fill tank with petrol of the correct octane rating as soon as possible.
• Fuel with a higher octane rating than that required by the engine can be used without limitation. There are, however, no advantages regarding output and consumption."

No, the ECU is retarding the timing based on the input from the knock sensors. You're constantly running on the verge of knock.
It's hardly a hard core sports car. It's a family 5 door with a 1.8t engine
I don't hoon around so asked if the car would be happy on lesser fuel due to the ecu altering the ignition timing.
The posts above question your statement as they seem to be ok on 95. I shall run mine out then top up with 95 and see what happens.
Thanks for the help guys
So you've asked for advice, being told basically to run it on 98 Ron, then decided to carry on running it on 95 Ron, good show sir, good show.
If you do the maths, you shall see that 95 Ron is a false economy. There is no benefit, whatsoever, to running 95 in a car that wants 98.
Just to confirm the above post, manufacturers don't always state 98.. I had a mk4 Fiesta and the handbook said to use 95, and 98 was of no benefit.

I agree with u mate. Tbh you can't help someone that don't wanna be helped. It amazes me even now people buying performance cars yet still have no idea on the very BASICS of performance driving! ie fuel, warming & cooling and quality parts.
Had a forum argument with a few folks ages ago and after page and page of info to PROVE 98 and above is better for car they were adamant that they knew more!!!!
Just the other day I see a RS4 fill up with 95 asda fuel! Ffs where do these people go to 'common sense school'? Dimbasses

thats right dolby you the man!
your attitude stinks.
if he wants to run on 95 ron, let him do it, you dont have to post saying that YOU know best, that YOU won arguments before.
it will not harm you or your pocket to leave his decision be, people run on 95 ron without problem or fault.
