Fuel expiry

[Wh1stl3r]

Due to the community quarantine our cars seldom get used. What is the real deal when it comes to fuel expiration in our local conditions? I have 2 months old gasoline and 3-4 months old diesel in our cars. It has been my practice to fill the tanks every visit to the pump to minimize water contamination from too much humid air in the tank. But now I'm starting to get worried the fuel system might get damaged from expiring fuel.

Can anyone shed more light on this?

on paper, 3 to 6 months yata.
but in practice, our four-month old fuel didn't give any trouble at all.
i filled up a week before the great quarantine. three months later, i drove the car out without any problem. it was still ok until the next fuel-fill a month later.

the last time we had issue with old fuel, was in the early days of ethanol blends.
after some months of queening the garage, the car wouldn't start anymore. after some kutingting, we determined it was fuel starvation. what we found, was surprising! the fuel in the tank had turned to... nata de coco! we had to buy a replacement fuel tank.

For Diesel fuel, bacterial growth is the one to look out for. They thrive when humidity is high.... and the rainy season isn't helping. These bacteria produces by-products that can clog fuel filters.

They say that, to slow down the moisture from getting in and prevent condensation in your tank, always keep it filled up with fresh fuel.

Diesel does not "expire" but as oj88 said it is the microbial growth that is the problem. These biologicals come from the ships that transport fuels as when the ship is unloaded it is necessary to fill the empty tanks with ballast water (sea water, in fact). Believe me it is not uncommon for us to find crabs and fish when we clean our main fuel tanks offshore. There are additives that are available for adding to diesel in order to mitigate these biologicals.

As for gasoline, the more volatile components will evaporate, leaving the less volatile, harder to ignite components in your fuel tank. BUT this is not much of a problem for fuel injected engines. Problema lang yan sa carburated engines.

whistly,

sa experience not really mine more of mga nakakwentuhan na ofws.

hindi na-istart kotse ng almost a year. Pinilit gamitin. Biglang ayaw gumana yung brake. So may aksidente nangyari pero buhay naman.

So kung sa bahay work from home eh twice a week istartin mo tapos bomba sa fuel pedal at depress brake na din. Yung asta nagdadrive ka pati kambyo galaw-galawin. Wag na din itaas handbrake. Kalsuhan mo na lang ng bato.

The gasoline car I'm not too worried about. Thing guzzles gas so I can probably use it up in a month or so. Problem with the diesel cars is they either have big tanks and/or are so efficient, with my current usage it'll take me a couple more months at least to use up all the fuel.

Have you guys used any of these fuel stabilizers/biocides?

Hmmmm 5 months hindi ako nagpa-gas buti wala naman problem..
Paano po ipa-check yung sa fuel?

If it still runs with no check engine light, just use them up. If the fuel is 5 months old, syempre mas mababa na quality ng sunog, though most vehicles will still be able to tolerate that.

ah akala ko po meron sinisundot na gadget or something para malaman yung quality ng fuel..

Kailangan pala sipagan ko na lang mag-drive kahit wala patutunguhan..
