im not saying they need it i just value the money i put into my tank and i have experimented with running 87 and 91 driving the same distance every day which is about 100 round trip using cruise control and i get on average between 150 to 200 km differance, last year there was a big thread about milage bud and there was a few of us that figured and read this CAREFULLY 87s15lt1 you better milage not performance with premium gas compared to regular gas

I had a very hard time understanding that…english please?
