Running a gt on 98 octane.
I did try using "search" but there was 47 pages of results sooooo... I always run 98 in all our cars because that's what subaru recommend but my GT fuel tank says 95... It's 7 cents a liter cheaper and filling every fortnight with 98 will cost an extra $100 a year, so it's not a money issue and it's not gunna hurt the engine but is there anything else I should consider ???
