    I think Seat recommend Super unleaded for the Leon FR.

    Does anyone use normal unleaded ? any difference ?

    Is there an additive like Millers which I use in my diesel ?

    sorry for all the questions !

    SEAT recommend 98 RON on the FR and Cupra which not all Super Unleaded meets, many are just 97 RON. Shell and Tesco are higher though.

    Mine wasn't keen on Sainsbury's Super the first time I used it, but think I actually have BP 95 RON in my Cupra at the moment, no difference in performance but the economy out of this tank has been ****

    Tescos super 99ron here.

    I tried Asda's 95 ron and my TFSI seemed to do even more ticking and rattling than normal so its been Teso's super only since then.

    I always use either:

    99 Octane ...Shell / texco / tesco (mostly tesco's) its so much easier with the self service.

    But you may lose performance.

    do you fill your Leon with 95RON then?

    SEAT also mention there may be a loss of economy as well on 95 RON.

    This topic has come up many times and there are people for and against.

    That article states "For many drivers, buying super fuel is "a waste of money" with people paying over the odds for the product."

    Which is correct as most cars are designed to run on 95 RON only and the manual actually states "There is no benefit in using a higher octane". Certainly this was the case with my recent cars.

    The 2.0 TFSi is however designed to run on a higher octane. Certainly the one in the FR and Cupra when I bought mine was (this may have changed since). I actually asked SEAT about this.

    There test is floored as they only used cars designed to run on standard fuel in which case, yes it won't make any difference. Certainly in a Focus 1.6 like they tested, super fuels will give little benefit.

    I chop and change between super unleaded and standard 95 ron in my 57 plate cupra and tbh i cant tell the differeance.
    The only reason i use super is its 5p a litre cheaper in Nottingham than London which is where my girl friend lives , and i just use it for the suposedly cleaning properties.

    But performance wise cant tell jack between them.

    It takes a few tanks in a row to get the benefit of 99 ron petrol as the ecu takes time to adapt.

    If the car is remapped then the car will take fuller advantage of super unleaded than a standard car.

    PS The only super worth using is either Tesco 99 ron (some not all stores) or Shell VPower
