It's probably not a bad idea to try and work it into a drive every 3-4 weeks, especially with how crappy modern ethanol gasoline stores (if that's what you use).

Agreed, probably a good idea to build that into my monthly routine.

I think all the high octane gasolines do have the ethanol, but started to put 91-92 octane gasoline for our sprinter.

We can get premium ethanol free close to home, but its $$$$ and not needed for anything we usually want to be ethanol free.

For long periods of infrequent use I think you would be better off with ethanol free 87 vs ethanol 91. I always top our rigs off with ethanol free if I anticipate the fuel being in the vehicle for more than 6 weeks.

Gasoline ( petrol for some ) just doesn't last all that long. I'd suggest driving it enough so you run through a tank every few months. I even try to do that with our Diesel van. They like to be run, stuff happens when they just sit.

As others have said, drive it like you stole it once a month or so or the emissions stuff gets gummmed up.

Machines seem to have the personality of a good dog. You gotta give them love and attention and they'll give it back.

I should consider this as well, appreciate the pointer!
(There is a gas station geared towards the boat owners, their premium is ethanol free.)

Mark,
Would you opt to leave the tank almost empty or fill-up full when you don't intend to drive, let's say 2 months period of time?

putting in boat gas would be better for sure,
I have an old toyota 4x4 that gets one or two yearly road trips ...before I park it, it gets filled with ethanol free fuel...hard to find in AZ but a few stations close enough to Tucson have it...

Seen few threads where the folks debated whether to go with 144 vs 170(ext), I've been preaching no differences and advised to go with 170 or 170ext, but I guess that's one downside of 170/ext, we exclusively use this thing for the camping (which we force to get out asses out there 5x annually), we have a big plan for next year to put more miles, which I plan to have it serviced at MB Lynnwood, WA prior to taking it out.
Some years ago, I was working an area far away from home base 6 days a week, so I spent all my time driving around a 26' box truck. It is surprising how easy it is to drive around a 26' box truck as a daily driver. Granted, I eventually secured permission to park Rudolf in the parking lot of the hotel I was living in at the time.

I have always stored vehicles with full tanks. There is less room for air and condensation with temperature swings.

Same here, I always fill up full prior to return home from the camping trips but I read somewhere about the myth buster, the fuel tanks used in 21st century auto industry doesn't exhibit this issue anymore.
But I still do it just because :)

Rust is certainly not an issue on modern tanks, but I can’t see how potential moisture issues wouldn’t increase with more air and thus more moisture in the tank. Climate probably has a big role too, it’s just easier to top it off especially if you store it with ethanol free and want to get that into the engine.

Would I keep my Ford Model T with full tank, now I would have 7, or so gallons of rotten gasoline. With carbureted engines, I always go extra way to run the carburetor dry, before putting it for storage.
But I left about a quart only, so it is easy to drain and refill fresh gas.
Since I also keep gasoline for generator at my cabin, I purchased steel gas cans, (European model) who keep gas under the pressure with 0 evaporation for long time. Plastic gas cans will let the light fraction to evaporate in a year, or 2, depends on temperatures.
But full tank storage is good for diesel, where I actually purchased a motorhome, who was park under the tree for at least 7 years and I burned the 120 gallons of diesel in tank to last drop.

@gas_sprinter did mention storage up to 2 months, even ethanol gas won’t be rotten in that timeframe.

There are times when empty is better, such as real long term. For my carbureted engines I also run them dry if it will be a while before I use them again, but don’t mind storing them with a full or completely empty tank but usually top them off.

do not overwork much on that, imho u have better chances of rodents chew your electric then fuel related issues or even late oil change

Our Porsche Cayenne Titanium Edition is a garage queen. :)

Lexus is a daily driver but we don't drive much. All within 2-3miles radius around our house except the longest travel being the Whistler, Canada.

Sprinter, parked on our driveway, but I spray mint extract hell out of the areas and been unpopular place for the rodents so far. But I plan to give a spin monthly after hearing from others.
 
gas sprinter, I suggest topping off that peppermint spray with sprinkling some hot pepper flakes before the spray dries out for an even better anti- rodent strategy.

In my experience, leaving the engine hood open works as well as anything, if you have a secure parking spot.

I neglected to open the hood for a few days recently and found a pile of the insulated blankets insulation on top of the steel rail that holds the radiator.

Fortunately I have not had to park on a street for decades, so leaving the hood open is safe and effective.
