Not to pick on you but i would say that you're wrong. just the fact that its a v6 doesn't mean use 87 because the rest have no benefit, it depends on the type of driver you are and what modz you have. its almost like saying just because its a 4cyl just use 87. my four banger had 388whp and the only gas i could use was 93 and the user manual said 93 is recommended and this is from factory so it all comes down to how you drive and how often you like to visit the pump (87 burns faster then 93)
this is not just towards you but all of the anti mid-grade and 93 ppl out there, and please don't get me wrong because i have 1/2 tank of 87 in my car now but its not a regular thing. i usually use mid-grade myself but ill use 93 next time around. Ive only had my car for four weeks now so this will be the first time ill be putting 93 in.
