MPG and fuel efficiency for the Infiniti G25
You can find detailed information on the 2012 Infiniti G25’s fuel economy and miles per gallon on this page.
The 2012 Infiniti G25 belongs to the Midsize Cars car category and uses premium fuel.
We have the data you need, whether you’re thinking about buying the automobile or you just want to know how economical and environmentally friendly (or unfriendly) your 2012 Infiniti G25 is.
Do INFINITI cars need premium fuel?
If you’re at the pump at one of our Eden Prairie gas stations and wondering whether to fill up your INFINITI with normal or premium gas, we’re here to tell you that the answer is yes. In order for your vehicle to operate as intended, INFINITI advises using fuel that is at least 91 octane.
What occurs if premium gas is not used in an INFINITI?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
“Use 91 octane or higher premium unleaded fuel that has been posted on the label. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.”
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
The Infiniti G25 is quick.
The 2.5-liter V-6 engine in the Infiniti G25, which has 218 horsepower and 187 lb-ft of torque, easily propels the entry-level luxury vehicle. Although the G25 has sufficient power for the majority of tasks, it never seems especially quick. The rear-drive G25 Journey variant we tested reached 60 mph in 7.6 seconds.
Is Infiniti G25 a reliable vehicle?
With a reliability rating of 4.0 out of 5, the INFINITI G25 is ranked fifth among luxury midsize automobiles out of 31. It has cheaper ownership costs than the national average due to the $533 average yearly repair cost. Major issues are rare for the G25 because the frequency of those issues is average and the severity of repairs is low.
Can I fill up my INFINITI with 87 fuel?
For the required performance and horsepower, INFINITI advises using premium unleaded fuel with a 91 octane rating. If you want your INFINITI engine to work as it was intended to for premium performance, fill it up with high-octane gas whenever you’re at the pump.

Can high-end fuel harm an engine?
If your engine works just fine on regular, adding premium won’t likely result in any substantial increases in acceleration or fuel efficiency. Whatever you may have heard, conventional gas today has the same detergent chemicals, therefore premium gas won’t do any more to remove deposits from your fuel injectors or other components of the fuel system.
As opposed to standard octane, which has an octane rating of 87, premium octane has an octane rating of 91 or higher. Premium gas has a higher octane rating, which makes it more resistant to early gasoline ignition, which could cause damage and occasionally be accompanied by loud engine knocking or pinging. More improved ignition timing, greater compression ratios, or forced-air induction devices like turbochargers or superchargers are all made possible by higher octane fuel. When given quality fuel, they work at their best.
However, you should only use 87-octane regular if the vehicle’s manufacturer specifies that it is all your engine needs. Though technically having less energy than lower-octane fuel, premium gas’ greater octane won’t make your automobile go quicker; in fact, the opposite may be true. When employed in the right engine, the fuel’s capacity to be compressed more without pre-ignition produces higher power. There is no such thing as “stronger” gas.
It’s definitely psychological if you buy premium fuel because you believe it makes your car run better: “I’m paying more for gas, so I must be receiving more,” you would think. However, some of that may be the result of favourable weather circumstances (such as warm weather instead of cold) or other causes. Some drivers claim they achieve superior fuel economy with premium.
You are treating the symptom, not the problem, if you use premium fuel because your engine knocks when you use normal. A mechanic should determine what is producing the knock and treat it if it is not carbon deposits or hot spots.
Depending on where you live, premium gas might cost anywhere from 20 to 60 cents extra per gallon. The return on investment will be limited if premium gas is pumped into a vehicle that was made to run on standard gas.
Can I fill up my INFINITI with 89 octane?
The premium fuel that your INFINITI consumes delivers the high-octane gasoline that the INFINITI engine requires. Use 91 octane premium unleaded fuel with your INFINITI to get the performance and horsepower you want.
Is g25x quick?
The transition to stricter CAFE regulations begins in 2012, and Nissan’s Infiniti Division is taking steps, like other automakers, to stay on the right side of the minimum mpg requirement. This new addition to the G-series sedan portfolio is a result of this. Rear-drive G25s get EPA ratings of 20 mpg city and 29 mpg highway, which are just slightly better than the 19/27 ratings obtained by a G37 with the same seven-speed automatic transmission and the only available transmission for the G25. The rear-drive G37’s mpg is matched by the all-wheel-drive G25x, which also has superior 18/25 ratings.
The G25’s justification also includes money. Its starting price of $32,275 is $4000 cheaper than that of the least expensive G37. The entry-level G25 Journey costs $33,675; the all-wheel-drive G25x costs $35,275. Additionally, the G25 delivers Infiniti a competitively priced entry against Lexus, whose IS range has a starting price of $33,520. Thus, Infiniti’s marketing geniuses perceive a win-win situation in which it gains from CAFE scorekeeping while also, it hopes, increasing market share for the G.
The VQ25VHR engine, which powers this mission, is brand-new to the United States and exclusive to the G-sedan lineup. But Nissan has had it for a while; in Japan, the Skyline lineup has included it since 2007. (In Japan, the G is referred as as the Nissan Skyline.)
It has the smallest V-6 currently available in North America, at 2496 cc. The tiny six was imported by Infiniti under the official justification that it was made for longitudinal rear-drive applications and that other suitable engines from Nissan’s North American stock were made for transverse installation and front-wheel drive mechanicals. Despite its small size, the 2.5 produces a solid 218 horsepower and 187 lb-ft of torque. Along with being incredibly smooth when combined with the seven-speed automatic, it is also quiet.
The G25 is slightly lighter than the G37, but sacrificing 110 horsepower and 82 lb-ft leads to predictable outcomes in the sprints: 0 to 60 mph in 7.3 seconds, about two seconds slower than the G37, and a few tenths slower than the most recent IS250 sedan we tested. The all-wheel-drive G25x we drove, which weighs 200 pounds more than a rear-drive G25 Journey, managed to reach 60 mph in 7.9 seconds and eventually completed the quarter-mile in 16 seconds flat at 89 mph.
But the remainder of the G25’s dynamic resume is quite enticing if stoplight-derby dominance is not a requirement. The rear-drive G25’s steering is precise and tactile, the transient reaction is quick, the braking performance is robust (165 feet from 70 mph), and the 0.93 g of traction provided by a set of Goodyear Eagle RS-A all-season tires (225/55R-17 95V) was a nice surprise. Even though the G25x stopped from 70 mph in 159 feet during our braking test, it only managed 0.85 g on the skidpad.
The G25 ranks as an appealing option with a good quantity of standard stuff and respectable driving manners. It is well-equipped, cozy, and appealing to look at. We’d much like it if it offered a manual transmission option, or at the very least paddle shifters for the automatic, and the lack of a navigation system option in an entry-luxury vehicle is puzzling. Nevertheless, the G25 appears to be a solid bet to carry out its purpose in the market despite these reservations.
What occurs if normal fuel is used in a high-end vehicle?
Engine knock is reduced by using premium gas, which has a higher octane rating. According to The Drive, 87 octane will almost immediately start the engine banging in older vehicles that need premium fuel. However, newer models of vehicles are more prepared to manage it.
Do the benefits of premium gas really matter?
In luxury and performance automobiles with turbochargers or high-compression engines, premium gas offers a stronger resistance to engine knock, allowing you to reach that horsepower effortlessly. Additionally, premium petrol can improve fuel efficiency, possibly resulting in longer-lasting better gas mileage while lowering pollutants.
Keep in mind that these advantages are only seen in vehicles that actually demand premium fuel, not necessarily in the majority of other vehicles. Note that the definition/label for premium gas can vary from state to state and station to station. Check your owner’s manual to verify what your manufacturer recommends for your individual automobile make and model.
How clean is premium gas for engines?
There used to be a significant difference in engine performance between cars using standard gas and premium gas. In order to overcome problems brought on by increased compression ratios, premium gas was advised for vehicles with higher performance engines. There were additives in premium gas that let these engines run as they were intended to and endure severe driving. The detergents and additives in today’s premium fuels assist clean fuel injectors and eliminate carbon buildup from inside engines, encouraging drivers of vehicles with regular-fuel engines to occasionally use premium gas to maintain their engines.
Depending on where you live, premium petrol might cost anywhere from 20 to 50 cents more per litre than regular gas today. At the gas pump, this may mount up quickly. While occasionally filling up with premium fuel may seem like a smart idea, it might not provide the benefits you’re after. Let’s talk about whether or not such expensive upkeep is cost-effective.
The main distinction between normal and premium gas is the octane rating. Regular gas has an octane rating of 87, whereas premium gas has a rating of 91 or higher. High octane fuel aids in preventing premature fuel ignition, which causes engine banging and can harm your car. In comparison to conventional fuel, high octane fuel may be heated and compressed more before self-igniting. Because of this, high-octane fuel is only used in high-performance automobiles.
