If this monster requires premium, then put premium into it. That is the price you pay for buying this behemoth.

if it recomends premium thats the minimum that should be used to prevent damage to your engine.. a few cents here and there is not worth it in the end when your engine could fail prematurely

The VQ35DE is a 10.3:1 high compression ratio engine. High CR engines perform better and last longer if you run high octane. Yes the engine has a knock sensor and the computer will retard timing to prevent engine damage due to knock. But there is a lot more going on than just knock.

If it says it requires premium, put premium (at least 91-93 octane) in it...

Read the owner's manual or download one from the Internet.
If it doesn't say use premium, then use regular and enjoy you 20-30 cent per gallon savings!

FYI to All,
I did NOT post the same reply twice. I clicked the "Post Message" Control Button and the Web browser reported some Site Errors and JavaScript Errors. When I clicked "O.K." to close the Warning Notification GUI, the Web browser refreshed and I saw the two identical posts.
I have reported it to GB. I reported some other errors over a week ago and GB stated they had some problems. That is all I know.

GB Member "dmwarren" posted, QUOTING: "A CBC study conducted by some engineers found that there really was no difference in the operation of most car engines when the owner used high test gas."
dmwarren, we appreciate your posting, HOWEVER, you NEED TO BE SPECIFIC when you quote and/or reference a Scientific Study. What you posted CAN be Misinterpreted or Appear WAY OUT OF CONTEXT. Even from what you posted, it appears -- remind you, I wrote "appears" and did not say it unequivocally was -- that you may not understand this study.
Be an ASE Certified Master Mechanic, with Specialty Certifications in Fuel Systems and High-Performance Engines, PLUS having worked in all phases of the petroleum and oil industries as a young man, I am more than qualified to address this study. I still have friends and engineers in those industries and asked them about this study. Their answers stated that this study was done on vehicles representing a general spectrum of those on the road. That specific test study vehicle group had about 82 percent of the vehicles that only required 87 (R+M Methodology) Octane or Regular Grade of gas as their engine's requirement. Therefore, using 93 (R+M Methodology) Octane or Premium Grade of gas in those vehicles did EXACTLY what one would expect. It neither helped, NOR HURT those vehicle's engine performance or fuel mileage. In THOSE SPECIFIC VEHICLES requiring only 87 Regular gas, the use of 93 Premium gas was, indeed, a "waste of money" -- your quote.
In this study, they also stated that those vehicles requiring 89 Mid-Grade or 93 Premium gas, their engines performance and fuel mileage was ENHANCED by using 93 Premium gas.
So when posted, QUOTING: "...really was no difference in the operation of most car engine..." AND "Basically they said it was a waste of money", it can be MISCONSTRUED or Misinterpreted by many readers. Those readers MIGHT infer that using 93 Premium gas in a vehicle where the Manufacturer states and/or labels it to use Premium is NOT a requirement, when in fact, it is.
THE BOTTOM LINE: Use what the Manufacturer of the Vehicle RECOMMENDS or Requires.
IF THERE IS A STICKER on the Fuel Cap, Fuel Tank Door or ANYWHERE one would see it when fueling that vehicle, then that is what is needed. Put that grade of fuel in that vehicle.

easy...follow owner's manual. Trying to save a couple bucks per fill up could end up more costly.
