l know a Lexus and a Cadillac need premium but l am not sure about Infinity??? Please help....thank alot!

no you have a car that can use 87 try a tank of 87 other than a 5 hp loss you will be fine

l dont think any car actually NEEDS premium, but if u can afford a cadi or a lexus whats another 10 cents a gallon?? catching my drift?? infiniti is dont need premium, just whenever u go fill up, once a month, add octane booster to the tank, itll give ur car a little more kick (probably nothing noticeable) but that will keep ur gas burning clean, & it will keep the fuel system from clogging up & make ur car start bogging, so basically if u can afford it, go with premium, but even if u r using premium at the pump still throw some octane booster in there & ur car will burn gas alot cleaner & keep it from getting sludged. hope everythings good later bro

l only put premium, I'd like to hear from a g35 driver that has been using 87 for an extended period of time if they notice a difference. Also a mechanic is opinion would be nice.

Your G35 comes with Nissan is 3.5 V6 engine which is a high compression engine its also one of wards top 10 best engines in the world for 12 years or longer. While this is a great engine u do need to put premium gas into it l have a G35 & a Maxima which has the same engine l put the cheap gas into my maxima one or two times shortly after my car started to shake & the service engine light came on. luckily all l
had to do was run two synthetic injector cleaners thru the tank & the car was back to normal.you should also get better MPG is too with the premium gas l get about 24 to 25 on my car & that is just in the city highway l get about 32 MPG. So play it safe & get the good stuff in the long run it will pay off if u do.
