    Anyone using it? Interestingly they state in some areas it is actually Ethanol free, going to take the Capri to the one in Glossop later to fill up, still going to add valvemaster though.

    There is a classic fuel supplier in Bredbury that supplies 105 Octane stuff but you need deep pockets, it's nearly 3 quid a litre.

    wrong question badly phrased ..
    Capri engines are designed to run on 4star .. nowadays due to modifications that is 98-101 RON petrol ..
    old style (since Aug/Sep'21) fuels changed from cheap 92-95 at E5 to cheap shit at E10 .. so that means poor fuel has up to 10% ethanol per weak litre ..
    compared to E5 - 0-5% ethanol per litre, but at the correct octane rating ..
    so now you protect your car against minimal ethanol corrosion, while running it at the correct octane rating.. Yes it appears to be more expensive..
    but in truth you should have been buying the correct expensive octane anyway - that is what your engine was designed to run on anyway ..

    I dont understand the fuss..
    Lead-free, protect with valve master or get the seats sorted..
    Ethanol at 5% - change the hoses and make sure you running correct spec - SAE J30 R9 - sorted..

    E10 fuels should not be causing a worry, because you shouldnt have been using that grade anyway..

    Can I respectfully disagree? I think you were missing my point somewhat.

    Wrong question? Nope perfectly reasonable, I'm asking has anyone used this product, I'm not trying to avoid paying the premium. I do apologise if you have explained this a hundred times and are fed up of such.

    I was more than happy buying e0 and paying the price even before the Capri, however there is a fuss around here as most places now only sell e10, I was quite pleased to find the 99 rated stuff.

    And I'm using valvemaster, I was simply asking if anyone was using this 99 rated fuel and if they had a good experience, perhaps I should have worded it better.

    Hi, sorry to jump in, but just wondered what this valvemaster is? Is it better than redex, and if so, how often does it go in?
    Cheers

    In my experience ethanol aside lead substitutes don't work. My 2.8 lost all exhaust valve clearance every 2k miles even with castrol valve master added. The only long term solution has been having hardened seats fitted.

    Agreed, at the time of "tidying" up my car, it was thought the 3.0 Essex wouldn't need the hardened valves so long as Valve master with octane boost was used.

    Have a look at my build thread in my signature, post number 341 onwards.

    So now even with the heads converted to unleaded, it still has the valve master added when using E5 higher octane fuel as a minimum, but as often as possible I use the posh leaded fuel
