Generator Maintenance by Fuel Type: Keeping It Ready
The saddest call I get isn't a generator that broke — it's one that simply won't start, because it sat neglected between storms. The good news is that keeping one ready takes only a handful of easy habits, and a few of them change depending on which fuel you run. This guide walks through all of it, in plain language, with a printable, 29-page version up top if you'd like the whole thing on hand.
Common Questions
1 How often does a generator actually need an oil change?
Most manufacturers call for an early break-in oil change after just the first several hours of use, then a regular change roughly every 100 hours or 6 months, whichever comes first — but check your own manual, since this varies by model. Clean oil is genuinely the cheapest insurance you can buy for a small engine.
2 Do I really need to run it once a month if I'm not in an outage?
Yes, and it matters more than people expect. Running it for about 30 minutes with a little bit of load keeps the engine's seals and gaskets lubricated, keeps fuel moving instead of sitting still, and on electric-start models, keeps the battery charged. A generator that only ever runs during actual outages is far more likely to let you down during one.
3 Why does gasoline cause so many more problems than propane or natural gas?
Gasoline is chemically less stable — left sitting, it starts to break down and can leave behind a gummy varnish inside the carburetor, which is one of the most common reasons a generator won't start. Propane and natural gas both burn cleaner and don't degrade in storage the same way, which is why generators run on them tend to need less fuel-system upkeep.
4 What's the single best habit for keeping gasoline fresh?
Add a fuel stabilizer to any gasoline you plan to store, and try not to let untreated gasoline sit for more than a few months. If you're storing the generator itself for a while, either run the tank dry or drain it completely — a half-empty tank of aging gasoline is the classic no-start setup.
5 Does the battery on an electric-start model need any special care?
A little, yes. Keep terminals clean and free of corrosion, and if the generator sits unused for long stretches, a trickle maintainer keeps the battery topped off without overcharging it. A dead battery on an electric-start model still usually has a pull-cord backup, but it's a lot more convenient not to need it.
6 This all sounds easy to let slide. Can you just handle it?
That's exactly what my yearly generator check-up is for. I'll run it, change the oil, check the filter and plug, look over the battery, and make sure it's genuinely ready — not just assumed to be. Think of it like an annual physical for your peace of mind. $99 flat. Call or text (330) 200-8042.
Want Me to Help With Yours?
Getting a backup generator picked, set up, and safe is one of the things I'm glad to do in person. I bring the patience and the know-how — you keep your seat. We'll get it starting, sort out the fuel and the safe hookup, walk through running your essentials, and make sure everyone knows the carbon-monoxide basics. $99 flat, and every visit is 30-day come-back-free. (330) 200-8042.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
