2012-2018

The 2.5-liter four-cylinder engine in the RAV4 produces 176 horsepower.  The RAV4 has three drive modes that vary throttle responsiveness and gearbox behavior (Eco, Normal, and Sport). 2012-2018 RAV4 also uses unleaded “regular” gasoline of octane number 87 and (Research Octane Number 91) or higher.

RAV4 EV vehicles were also sold from 2012-2015 in the US. The electric motor in the RAV4 EV is powered by electricity stored in a rechargeable traction battery. Regenerative braking is used to store electricity in the traction battery, extending the driving range. This technology is clean and has a low environmental impact because it does not release CO2 or NOX during operation.

2006-2011

Two powertrain options are offered for the 2012 Toyota RAV4. The standard engine in the RAV4 is a 2.5-liter four-cylinder with 179 horsepower and a four-speed automated transmission. Those seeking more power might opt for the 269 horsepower 3.5-liter V-6 and five-speed automatic, which propels the RAV4 from 0 to 60 mph in just over six seconds. Both engines are available with front-wheel or all-wheel drive.

2006-2011 models of RAV4 uses unleaded “regular” gasoline of octane number 87 and (Research Octane Number 91) or higher with an octane rating lower than 87 may result in engine knocking.

1996-2005

The RAV4 has only one engine option: a 2.4-liter four-cylinder with 161 horsepower and 165 pound-feet of torque. It’s available with a five-speed manual or four-speed automatic transmission. The optional automatic transmission has a smooth shift pattern, and rapid downshifts.

The first generation of RAV4 EV vehicles was sold in 1997-2003.

 It uses unleaded “regular” gasoline of octane number 87 and (Research Octane Number 91) or higher.

What Type Of Gasoline Can Or Can’t Be Used?

Besides conventional fuel, there is a wide variety of gasoline available in the market. Many of these for RAV4, some enhance the drivability while others affect the performance adversely. Let’s take a look:

Gasoline Containing MMT

MMT (Methylcyclopentadienyl Manganese Tricarbonyl) is a 50-year-old octane-boosting gasoline additive. Extended usage of MMT has raised concerns about the formation of Mn-containing deposits on engine and emissions system components, which could compromise vehicle emissions performance and durability.

Toyota does not suggest using MMT-containing gasoline. If you use MMT-containing fuel, your emission control system may be harmed, and the instrument cluster’s malfunction alert lamp may illuminate. If this happens, contact your Toyota dealer for service.

Addition Of Detergents

Toyota recommends the addition of a cleaning agent in gasoline.

Detergents are required because they maintain parts of the fuel system clean and avoid excessive carbon buildup in injectors, feed valves, and fire chambers. They can restrict proper airflow, change the fuel/air balance, impair fuel economy, offer less fuel economy, and increase vehicle emissions.

All gasoline sold in the United States contains a minimum level of cleaning agent additives. Toyota recommends you buy gasoline from TOP TIER retailers who sell gas that has been proven to keep your engine cleaner than non-TOP TIER retailers. You can find such retailers at toptiergas.com.

However, there may be instances in which TOP TIER gas is not available in your region. In this case, you likely fill up at BP, Amoco, Walmart, or 7-Eleven. All these brands aren’t TOP TIER retailers and you need to add a detergent to your gasoline to keep your engine clean or deposits will build-up, reducing MPG and the lifespan of your fuel system.

In this case, we recommend you go with a product like Hot Shot’s Gasoline Extreme and Stiction Eliminator. Gasoline Extreme cleans the complete fuel system whereas Stiction Eliminator focuses on the sticky, gummy residue of burnt oil in the engine. Furthermore, these products don’t contain metallics or silicon and are guaranteed to not void any warranty. It’s the best option if you can’t fill up with TOP TIER gas in the first place.

Gasoline With Ethanol

Most modern cars can run on ethanol and non-ethanol fuel mixtures up to E15 (15 percent ethanol). Flex-fuel vehicles, on the other hand, can handle up to E85 (85 percent ethanol) without issue.

When the gasoline in your vehicle has too much ethanol in it, strange things happen to the computer’s perception of what it’s seeing. The computer assumes the gas is 10% or 15% ethanol but notices that the density (weight) of the gas and the emissions it produces don’t match up with what it thinks it’s seeing.

The computer assumes the gas is 10% or 15% ethanol but notices that the density (weight) of the gas and the emissions it produces don’t match up with what it thinks it’s seeing. The computer will believe the automobile is running on a “low” fuel combination (too much air and not enough fuel).

As a result, the computer responds typically by injecting too much fuel (to address a problem that doesn’t exist), reducing your car’s gas mileage and performance. Proper care should be taken while filling the tank, as if gasohol spills over on the car, then it can tarnish your vehicle’s paint.

Octane Rating Of Fuel

Octane rating helps us to determine the fuel rating. The octane rating, sometimes known as the octane number, is a scale from one to one hundred that describes a fuel’s ability to resist compression and avoid knocking.

The octane number is not a measurement of the fuel’s energy content (that is, its calorific value), but rather how linearly it will burn when ignited rather than exploding in an uncontrolled manner.

Toyota recommends using a regular octane with a rating of 87. If we use an octane rating lower than 87, you can hear a persistent heavy knocking sound. At worst, it can also damage the engine. Also, if you use a higher octane rating higher than recommended, it may deteriorate the performance. 

Does the RAV4 Have A Good Gas Mileage?

2019-present

The RAV4 earned class-competitive fuel-economy estimates from the EPA. The all-wheel-drive hybrid delivers a mileage of 41/38 MPG on highway/city and combined mileage of 40MPG. All-wheel-drive RAV4s can manage up to an estimated 34 mpg on the highway.

What If Your Engine Makes A Knocking Noise?

There are several reasons due to which there is a knocking sound in your engine. When fuel burns unevenly in the engine, a knocking occurs, resulting in an annoying noise and potential damage to your engine cylinder walls and pistons.

Knocking sound is also very commonly heard if you are driving uphill or accelerating; there is no need to be concerned in that situation. You may generally hear a slight knocking sound sometimes, but if it is persistent, then it is a problem.

You may have used fuel with a lower octane rating than 87. The lower octane fuel burns more readily under pressure and ignites spontaneously when subjected to too much pressure.

Solution- Adding an octane booster to your Toyota tank will increase the octane to a better range of the currently installed fuel. After the tank gets empty, you can refuel it with the proper rated fuel as mentioned in the owner’s manual of Toyota RAV4.

How Much Does It Cost To Fill Up Toyota RAV4?

On average, it will cost you around 70 dollars to fill up your RAV4 tank once in California, the state with the costliest petrol, while it will cost you only 45 dollars if you are getting your tank filled in Mississippi, the state with the lowest petrol price in the US.

If you have an older version of RAV4, filling the tank can cost you around 65 dollars in California and 42 dollars in Mississippi.

These are the prices for regular gasoline in the states. If you are filling higher-grade gasoline, then the cost is expected to rise.
