Hi 87 if you are in the USA 91 if you are in Europe The difference is caused by a different system to determine the octane value and both actually mean the same. R (research) - for Europe (R+M)/2 - (research + motor divided by 2) - for the US Keep in mind that higher octane fuel has less energy so if you go higher than recommended you are just wasting money.
