Zoom on the Ryobi RY906500S
In summary, the Ryobi RY906500S is a portable generator especially useful for:
- Food van owners who know that just a short power outage could lose them hundreds of dollars
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to be able to deliver results, even during a power failure
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.
Power & Run Time
The Ryobi RY906500S's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6,500W and reaches a peak wattage of 8,125W.
The generator features Ryobi's EasyStart pull-start mechanism (more information below). It is rated for a noise of 72 dBA (just slightly more noisy than a shower).
The fuel capacity of 6 gallons allows the RY906500S to operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH).
The control panel provides the upcoming 5 AC outlets:
As it features a twist-lock L14-30R receptacle, the RY906500S is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
The design of the Ryobi RY906500S is a typical, open frame, with the dimensions of L39 x W29 x H24.5 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Since the generator weighs 195 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
To help you monitor the RY906500S's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
It also includes a carbon monoxide sensor. This sensor is designed to monitor the level of carbon monoxide present during the generator's operation. If the generator is positioned incorrectly and carbon monoxide levels rise to an unsafe level, the LED on the sensor will flash red and the generator will automatically shut down.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Ryobi RY906500S, the following accessories are also included: oil and tool kit.
The Ryobi RY906500S is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor and therefore, can be used in forested areas.
The Ryobi RY906500S versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY906500S compare to generators of similar power (between 6000 and 7000 W).
- Since the generator weighs in at a dry weight of 195 lbs, the Ryobi RY906500S belongs in the expected weight range for devices which can produce between 6000 and 7000 rated watts. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
- As this generator can emit noise as low as 72 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Powerhorse 7500i, one of the least noisy generators similarly powerful as this one, rated for 55 dBA.
- As far as autonomy is concerned, providing around 10 hours of runtime with a full tank at a 50% load, the RY906500S falls into the low end in comparison with other devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen6000, as it provides around 13 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.6 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the A-iPower SUA7000L, which has a fuel consumption of only 0.36 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 6000-7000W generators, the Ryobi RY906500S is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.

Who makes the engine for this generator. (Asked July 13, 2019)
The 420cc engine of the Ryobi RY906500S is manufactured by Ducar.
What type oil is recommended for the RY906500S? (Asked April 24, 2020)
For general, all-temperature use, SAE 10W-30 is recommended.
Can you get in inverter to connect with the model RY906500S? (Asked June 10, 2020)
Unsure what you are trying to achieve. This unit outputs AC power. An inverter converts DC into AC. If you need clean power, you should consider an inverter generator.
Both my oven and A/C need 50 amps. Will this unit be able to run my oven and A/C during a blackout? (Asked June 14, 2020)
This unit does not feature a 50-amp outlet. Assuming that you were talking about their combined draw, and that they both operate on 120V, you'd be pulling 6000W out of the 6500W. As we recommend to keep the load under 80%, you should be looking at a unit able to deliver around 7500 running watts.
How many gallons does it use per hour? (Asked July 09, 2020)
Fuel consumption depends on load. At 50% load, it should be around 0.6 gallon per hour.
Is this unit OK to operate in the rain? (Asked August 03, 2020)
Please refer to our article on rain and snow operation, which applies to any existing unit.
What kind of gasoline does it use? Is just regular unleaded or a mix? And which mix? (Asked August 26, 2020)
Gasoline should be unleaded, with no more than 10% ethanol. The engine is 4-cycle, so gas shouldn't be mixed with oil.
Can you convert this generator from gas to natural gas? Is there a certain converter kit you need to make this happen? (Asked August 27, 2020)
There are no official conversion kits.
what is the oil capacity on model RY906500S generator? I purchased new and without oil. However, a bottle of oil came with the unit. It is 32 fluid ounces. How much do I put in the generator? (Asked August 28, 2020)
Engine oil capacity is approximately 32 fl. oz.
Is there a special kit to purchase to attach to breaker box (Asked October 04, 2020)
The L14-30R outlet allows for an easy connection to a majority of transfer switches. This connection should be done by a licensed electrician.
what are the little black "buttons" next to the outlets and how do you use them? (Asked December 21, 2022)
These are reset buttons for the circuit breakers. Circuit breakers will automatically switch OFF if there is a short circuit or a significant overload of the generator at each receptacle.
