Hello Was just wondering if you guys were running premium fuel in your v-6's like they recommend? Or if any of you are running the ethanol blend, in our area we have a 10 percent blend option. And have you seen any difference running the different octanes? Thanks

I'm running 87 Octane in my '07 V-6 Taco just like the owneres manual says. It also says you can use higher octane if you want but I don't see any reason to do so. The stuff we have available also has 10% ethonal and we don't currently have any other choice. TacoGuy

I use 87 unless if I am towing then I usually go 91 just because the manual also says you will get more power with premium.

I've experienced less downshifting, slightly better mileage(approx 2 mpg) running 89 octane or better. However, little or no difference 91 vs 89. Reading into members with scangauges..this seems typical. My setup...V6/Auto/4X2
