The Infiniti G35 requires petrol with an octane number of 91 or higher, ie premium petrol. Do not set anything lower than this as serious engine damage may result. The gas in the cylinders will detonate incorrectly if you use an inferior gas, resulting in loss of power and engine damage.
INFINITI recommends using premium 91 unleaded gasoline for desired performance and horsepower. Your INFINITI engine requires high octane fuel to run because it is designed to deliver class-leading performance. So always treat it with the right fuel when you’re at the pump.
Your INFINITI uses premium fuel, which provides the high-octane gasoline that the INFINITI engine requires. For the desired performance and horsepower, it is recommended that you use 91 Octane Premium Unleaded Fuel with your INFINITI.
If you’re at the pump at one of our Eden Prairie service stations and ask yourself, “Should I use regular or premium fuel in my INFINITI vehicle?” we’ll tell you, the answer is yes. INFINITI recommends the use of at least 91 octane fuel to ensure your vehicle performs as it was designed.
Using Regular Gasoline in an engine that requires Premium may void your warranty. This is most likely to happen when regular use causes severe engine knocking or ringing (premature ignition of fuel, also known as detonation), damaging pistons or other engine parts.
So I know you’re supposed to fill the G35 with premium fuel, but I also remember reading in the manual that the engine changes its timing when lower octane fuel is put in the Tank is filled to accommodate .
Luxury cars may require premium fuel if they have a high-performance or turbocharged engine. Even if you’re not buying a luxury car, more luxurious trim levels for a car may offer engine options that require premium gasoline.
The car is premium only! It’s only optimized for Premium, only use Premium!
Luxury cars require premium gasoline to operate with greater fuel efficiency and to maximize their speed and performance. While you could use regular gasoline in a luxury car, long-term use will cause your engine to experience additional wear and potentially void your warranty.
In a consumer notice, the Federal Trade Commission states, “In most cases, there is absolutely no benefit to using a gasoline with a higher octane rating than recommended in your owner’s manual. It will not make your car more powerful, go faster, have better mileage or run cleaner.”
Are Infiniti G35 reliable? Reliability ratings of an Infiniti G35 can vary by model year, but overall it’s considered a fairly reliable vehicle. JD Power gave its latest model, the 2008 Infiniti G35, a 4.5 out of 5 for reliability. Meanwhile, the data analysis company gave the 2007 Infiniti G35 a 3 out of 5.
Unfortunately, there is nothing in premium petrol that makes it last longer than other fuels from the pump. Since the differentiator is higher octane, the only real benefit you gain is a reduction in the likelihood of engine knock, which is not a major threat with most modern fuel systems.
The higher octane rating gives premium gasoline greater resistance to early fuel ignition, which can lead to potential damage, sometimes accompanied by audible engine knocking or pinging.
In most cases the vehicle will run fine, but you may notice reduced performance and fuel economy. In more severe cases, you may hear engine knock or valve clatter because the fuel is not combusting properly. These things could damage your engine and you should take it to your mechanic.
Yes, drivers can mix the two types of fuel. The combined gas types result in an octane rating somewhere in the middle – something the vehicle “will survive,” according to The Drive.
Most cars on the road recommend a standard 87 or 89 rating. Super 90-93 petrol is perfectly fine for a standard vehicle. Car experts say there is no risk of damage in a standard car using premium fuel.
