Maybe, maybe not. We do not really know... You really do not need to try and bash Nissan on everything. We can do that about ANY car company, Ford included. As long as there is human involvement, there will be somthing shady somewhere; all humans are imperfect.

However, it does not matter what Ford is saying in terms of HP. The 5.0 is way underated anyway. It is really pushing out about 430 HP...

Always sneaking in a jab here or there.

Well, he hasn't made any personal attacks so I guess he's operating within the rules. Sometimes I question his motives...

NiZZZmo370 · 10-28-2010, 01:54 PM

I'm pretty sure it has to do with the engine and the compression ratio...If you have a Z, why not put the best in it...(Premium Gas, Synthetic Oil, etc).

PapoZalsa · 10-28-2010, 02:11 PM

I had an Acura Integra GSR 2001

that required Premium Gas.

NiZZZmo370 · 10-28-2010, 02:17 PM

I know my GTR also requires premium gas lol and same with my 370Z...I just listen to the rules, sucks now though because of my GTR's tune, I have to put higher octance fuel.

It's all about detonation resistance... when you have a high-specific-output powerplant like the VHR with high compression and timing pretty near MBT from the factory, you need the extra detonation resistance of 91+ octane fuel. With a factory tune, you'd probably be OK running mid-grade but the ECU would pull timing due to a minimal amount of knock. 85 octane would be a serious no-no unless you never rev above 3000 rpm at half throttle.

Interestingly enough, you'd get better mileage on 85 octane up until the point that the ECU started pulling timing due to knock.

No-need to attack anyone personally. Sometimes there needs to be a devil's advocate, though. However, personal attacks really are unwarrented.

I agree. People will buy a sports car/high-dollar car and then want to run in it what they run/ran in their beater.

You don't feed a supermodel hamburgers and hotdogs.
