running a generator non stop - will it hurt anything?


Recommended Posts

been living on a 6.5kW generator for the last three days now up here in middle New York

the generator - a Yamaha gasoline engine on a Homelite portable wheeled chassis - has been running almost nonstop for about 60 hours now, with only about 10 minutes of downtime this morning when it ran out of fuel. other than that we have been refueling it live. it was bought a year ago and prior to Tuesday it had maybe 12 hours on it since new. as far as we know, the load is well within the continuous output capacity of 6500 watts.

what i would like to know is, will it hurt or put excessive wear on anything to have this run for another 72 hours? 96 hours? should the machine be allowed an hour or few hour break? how often?

the electric utility company says its going to be at least a few days longer due to the weather getting worse as the week goes on.

When I was in the Army and we had to run off generators in the Field- It was customary for us to shut off power every 6 hours to check the oil and air filter as well as to fuel them up. (these were diesel though) ,

But you should probably read the manual... and occasionally shut it down to check the oil and air filter as well as to refuel. ( I would say every 4 - 6 hours to check the fluids then let it sit for at least 10 min ) not to mention if the belts are visible then check them. (some have chains and those you have to make sure are lubed) . Not to mention you should see if there are any lube points- though probably you are snowed in and don't have a grease gun.

If not then look online for a manual- usually they have a general maintenance section.

Also to note make sure that it is in a well ventilated area.

Though after this period of use you may want to consider getting the oil changed in the generator as soon as the weather clears.

is it a premium series or an inverter series of their generators? If your generator says it's 6500W then that is PEAK, NOT CONTINUOUS. Do not operate at a maximum power for more than 30 minutes. For continuous operations, do not exceed the rated power.

For example their E6600DE is 6600 watts peak, but 6000 continuous (which is still quite high because normally continuous is 50-60% of peak) with a running time of 7.4 hours at rated load.

Check out the current ones here: http://www.yamaha-motor.ca/products/index.php?group=G

i'm positive its 6500 continuous watts. no worries there, i know the difference between peak and continuous output. by the sound of the gen outside, we aren't even getting close to the continuous max for more than a little while at a time.

i am more worried about the engine really, but at least its cold, not hot, out there right now being the middle of winter so it won't overheat or anything. i will see about checking the oil tomorrow, something we forgot about really. as for shutting it down every few hours, its not going to happen with my family. dad dumps gas into it while its running as it is.

the manual is long hidden away and i'm not going outside to find out the model. it seems to be holding up well.

the power definitely isn't clean, the blower in the furnace is a tad quieter (and slower) and the incandescent lamp in our fridge has a noticeable flicker depending on the load. but it seems to be holding up well. it powers enough of this household to keep all 4 of us happy. energy efficient integrated florescent light bulbs (the 15w kind that screw in to replace regular 60w bulbs) are used in all other light sources and they operate just fine.

its connected to our mains box with a cable that provides two leg power (2x120 or 240 volts). we are careful as to what is running. so far its lighting, two small televisions, a 3 month old fridge, a trailer-sized oil burnig furnace from the 70s that is running about 60% of the time, cable modem and router, three laptops plugged in and powered on, a water pump hooked to an underground well, and for a short time this afternoon, my Oki LED page printer. if we kill the heat, the water heater can be run, usually for 30 minutes or so at a time we give it.same with the clothes dryer. no light dimming here, though i wish i had a P3 Kill-a-Watt handy

thanks for the replies, im going to sleep now :)

Do you really need power 24 hours a day?

Why not just run it for a few hours every once in a while to have the furnace run? I hope you don't have neighbors.. Power went out here a couple weeks ago at midnight and some ******* a door down fired up his generator at 1am and ran it all night. Needless to say that's the closest I've ever come to committing a crime (vandalization / sabotage of a generator).

If you have a fridge/freezer... yes you do need power 24 hours a day.

a Decent fridge and freezer should keep the cold for a considerable amount of time before they need power.

Freezers also last up to 3 days. fridges not so long but still depending on how often you open it it should last 12-24 hours.

Not sure what a gen like that can handle but whole home ones are great

connect right to your power and it auto switches on when the power goes out... nice to have them and they run off natural gas so no refilling

dad is thinking of a 12000 watt diesel for a future upgrade, as it would be more than enough to power *everything* we normally use. natural gas would be nice, but i think he'd go for diesel because it could easily be hooked into our heating oil tank and would burn slightly cleaner for a cheaper price per gallon than standard road vehicle diesel fuel.

all else: turning off the heat for an hour makes the place pretty chilly, but the fridge temp creeps up to 50 degrees which isn't good for our food. tomorrow we plan for a two to three hour break.

and about the noise? there are at least 5 generators running on our road at any given moment, although i think we might be the only ones running one constant.

First off why do you need to run a freezer 24 hours per day? It is winter outside and you could put the stuff in a cooler and leave it outside unless of course the temperature is above freezing. Second of all that is why it is always good to have a wood burning stove in situations like that where power could be out for days. Luckily during the ice storm about 12 years ago it was only for a stretch of 8 hours that we were out but had constant loss of electricity.

Turning the heat off for an hour makes the place chilly? You probably have lousy insulation if that is the case and to save energy should put on more clothes. Sheesh talk about panzies.

When our power went out because of the wind storm in the Midwest, we ran our generator 12 at a time, and never had any issues except the noise. I used good quality fuel and Castrol oil, with some Jacobs added to the gas and oil. It worked great. We had 2 freezers, and a refrigerator, and they were fine with only 12 hours a day. The trick is to keep the freezers covered to keep the cold in. We had no power for 6 1/2 days.

We are planning to get a whole house generator, Costco has a 10k NG/PG unit (12k PG) that comes with auto 100 amp switch box (it will cover up to 150 if you upgrade), which is more then enough to power my house. It can handle most homes, and only cost $1997.99. It is a little larger then an air conditioner, but something that i plan to get, (the batteries for my UPS are getting to costly).

You don't need a fridge or freezer at a time like this, just pack your food in bins, and then bury the bins in the snow to keep it cold. I've worked with generators before, run it twelve hours on, then three hours down.

aren't your powerlines underground or something? I know a lot of snow has fallen, but really, a few days without power? There would be riots if something like that happened here, no one even has a generator over here :D

nah over here in America our power grid is old and unreliable. very newly built areas usually have utility lines underground and inner city areas of course have all wiring, fuel, and water lines buried

but not out in the woods where i live, here everything is suspended in open air on poles.

147000 customers in the dark is the power co's estimate as of last night

Not had a proper power failure here in years. When we do get a failure they last an hour or two at the most. I suppose we're lucky with underground utilities in much of the UK. I suppose it's worse out in the country with the traditional suspended lines.

I hope you get your power back soon.

    • Waymo recalls self-driving software after cars enter closed freeway work zones by Paul Hill Waymo, the self-driving car maker owned by Alphabet – the parent company of Google –, has recalled some of its fifth-generation Automated Driving Systems (ADS). It did so after some of its cars drove through closed construction zones. According to the National Highway Traffic Safety Administration (NHTSA), the affected vehicles were capable of driving through a closed freeway construction zone and continuing to drive at speed. The listing on the NHTSA website says that Waymo is currently developing a solution to fix this issue, but in the meantime, freeway driving is being restricted. Waymo will update its ADS software so that vehicles can detect when they can avoid entering construction zones. According to the Safety Recall Report, on April 20, 2026, Waymo’s Field Safety Committee began meetings reviewing an event from April 11, 2026, and five events from April 19, 2026, where Waymo’s autonomous vehicles didn’t recognize and drove past ramp closure signs into the pre-planned freeway construction zones. This took place in Phoenix, Arizona. Separately, on May 18, 2026, seven Waymo vehicles entered freeway lanes with active construction in the San Francisco Bay Area by driving between cones that were placed to show the lane was closed. On the back of both of these events, Waymo restricted freeway driving until it could address the issue. In June, Waymo’s Safety Board reviewed the issue and additional information related to ADS performances around construction zones; then, as a result, it decided to conduct a recall. This development is not good for Waymo as it adds to a growing list of technical hiccups its cars have experienced. Ultimately, it will lead to more scrutiny from lawmakers around the world who will be more cautious about letting autonomous vehicles on their roads without tighter regulation. For readers in areas where Waymo operates, does this news make you more wary about stepping into one of these vehicles?
    • I'm still on Windows 10 22H2 because I didn't want to deal with all the issues in Windows 11, so I waited almost a week before installing the latest Patch Tuesday update (KB5094127), I went ahead and did it, and it was a huge mistake—ever since then, my File Explorer has seen a performance drop of about 30% when transferring large files... Once again, Microsoft has outdone itself! This update cannot be uninstalled, either through the Control Panel (via Settings) or by accessing Advanced Startup Options. The only possible alternative would be to use system restore points, but I’d have to reinstall all app and driver updates (and there’s no guarantee it would work). Or there’s the “nuclear option” of a in-place repair without losing files or apps, but even then, all my customizations would be lost! Microsoft just can’t help but mess everything up! Way to go, Microsoft! But I still don’t want your c****y Windows 11!
    • Microsoft: Windows 11 could finally solve a major issue across AMD, Nvidia, and Intel GPUs by Sayan Sen While Microsoft has been trying to improve it, Windows 11 is definitely not flawless, as even today some issues are taking a year to publicly acknowledge. However, one area of trouble that may finally see much better results soon is graphics driver crashes. Work on graphics driver timeouts, also called Timeout and Detection Recovery (TDR), is not new as the latest WDDM 3.2 also has specific improvements regarding it. Windows Display Driver Model (WDDM) version 3.2 is supported on Windows 11 24H2 and 25H2. However, with the upcoming version 26H2, TDR crash diagnosis could go to the next level as Microsoft is introducing a new DirectX 12 API feature called "DirectX Dump Files". Similar to how system memory dump files work when a system crashes or freezes or encounters any such major issue, DirectX Dump Files (DDF) will essentially record a snapshot of the GPU execution right at the moment a graphics-related crash or hang or freeze occurs, so that developers can better understand and diagnoze these TDR and timeout detection errors. The dump will be available as a .dxdmp file for analysis and it will be a comprehensive dump file generated with detailed insights about the hardware, drivers, Windows, as well as the affected application. This should be another welcome change in this department. Earlier at GDC 2026, when the technology was first debuted, Microsoft had shared more details regarding it. The company had explained how DDF is designed to gather data from every layer of the graphics stack into a single file, eliminating the need for developers to manually correlate logs from multiple tools. As mentioned above, the dump can contain a lot of useful details like GPU hardware state information such as register values, shader program counters, page fault virtual addresses, shader memory data, and command buffers. Alongside that, it also captures DirectX runtime and kernel information, including D3D objects, pipeline state objects, device error data, adapter details, and CPU call stacks. Microsoft says the feature has been built around two primary use cases: retail device removals and local device removals. The former allows developers to collect crash information from end users' systems in the field, while the latter helps QA teams and developers investigate issues on test machines. Developers will also be able to include up to 2 MB of custom application data through new D3D12 APIs, providing additional context for troubleshooting. In addition, Microsoft is introducing three dump collection modes ranging from zero-overhead capture, which has no runtime performance impact on supported hardware, to higher-detail modes that collect more vendor-specific debugging data. On compatible Tier 2 hardware, zero-overhead dumps will be enabled by default, meaning developers may begin receiving useful crash diagnostics without making any code changes. The table below explains the three tiers: Tier Description NO_OVERHEAD Enables crash capture with no runtime cost and is suitable for broad deployment MEDIUM_OVERHEAD Provides a balance, capturing additional diagnostic data with moderate impact HIGH_OVERHEAD Collects the most detailed GPU and driver state available, enabling deeper investigation at the cost of higher runtime overhead In terms of availability, the company expects broader release to be around the fall of 2026, which should be right around the time when Windows 11 version 26H2 lands. Right now, DirectX Dump Files are available as a preview and currently, only AMD has the compatible AgilitySDK Developer Preview driver version 26.10.07.02. You can find the official announcement post here on Microsoft's website.
