I was gonna ask this on the car specific forum for my particular vehicle (I'm talking about my Infiniti FX35 daily commuter), but figured they'd give me an answer of if you wanna protect your baby, use the best gas kinda answer, so here goes- after running 50+ miles per day roundtrip to work each day for over a month, I recently discovered that although the manufacturer "recommends" 91 grade fuel (premium) for best performance, the SUV technically only needs 87 grade fuel (finally read the friggen manual). So, with my calculations, that amounts to a savings of about $300 a year if I run regular gas now.
So, my question- should I just run the 87 from now on? I don't need the extra power/performance from 91 as I'm just using the thing for commuting, and an extra $300 a year is a nice dinner or Boxster mod , but I don't want the hassle of having engine problems down the road if running 87 will cause engine deposits/knocking issues over the long haul. What do you guys think? Continue running 91, or switch back down to 87?

Re: Your manual isn't saying all it needs is 87 octane; it's saying you can get by with 87 . . . John Brown of SE SoDak - Wednesday, 29 December, 2010, at 12:50:55 pm |
