I've gone ahead and bought the Triple QX from Euro Car Parts. I checked the label first and made sure it met the JWS3309 requirement and it does. It should be £45 but with a 30% discount it was great value at £32. I've included images below of the labels so that anyone else can check this out before buying and if you want the 30% discount, order online and at the checkout use the voucher code LASTCHANCE30, it's valid for another 2 weeks. You can actually use the code on anything from Euro Car Parts, I hope someone will find the code useful.
