i always put 98 ron in my car and have no problem with the cost or anything

but heres my problem i dropped a bottle of NOS octane booster in my car and it feels 10 times better

that tells me that the focus needs atleast 100 ron fuel

hmm i have used octane booster in my previous car and felt no real improvement, perhaps slightly better fuel economy but really when you consider you just spent 20 bucks on a tiny bottle its not worth it because for 20 bucks you could of got 18 litres of petrol... think about it lol

If you use NF octane booster you only need 1 ml per liter to give the same result :)
You would get 6 may 7 tanks out of 1 bottle.
Big difference !!!!!
