Always Running on Low Gas, what are its damaging effects?

[attyallanlatras]

I have the habit of running on low gas, that is, nag-red light na ang gauge ko. I run for as long as around 10 km before my next gas fill. But I never had an occasion na naubusan talaga ako ng gas. Is there any adverse effect on this on the engine?

If the car is old, it will pick up the sediments and grime at the bottom of the tank...

Or if you push your luck and the car stalls...

You might run out of gas like what happened to me in the Jimny (buti na lang in front of Petron Visayas Avenue).

Or your engine will suck in the dirt at the bottom of the fuel tank. Just hope you have a good fuel filter. But even that can get clogged prematurely.

Thanks. What how many liters ba ang reserve sa gas tank, after mag-red light na sya?

Depends on the vehicle. See the owner's manual. On the Patrol (with a 95l fuel tank), it usually equates to around 10L. On smaller cars, a 5L reserve is the norm but better to countercheck with your manual first.

Mine is an Innova gas. The manual says its 55 fuel tank, so ilan kaya dun and reserve after mag-red na fuel gauge?

Hindi naman gumagalaw ang "sucking end" ng fuel system, eh. Kahit full tank pa iyan, sa bandang ilalim pa rin naman ng fuel tank sumisipsip ng fuel. So, kahit full or almost empty tank, there is almost no difference in the amount of dirt being sucked in. Unless of course, you always fill it up with dirty fuel which adds a SIGNIFICANT amount of dirt on every fill up.

I say it's okay. Besides, hindi naman sagad sa ilalim ng tank yung hose na panipsip, may allowance pa rin naman iyan para sa sludge build-up.

another thing kapag palaging tuyo ang inner wall ng tangke natin mas prone ito sa moisture build up lalo't malamig panahon. again kung pwedeng palaging may laman why not para iwas impurities.

I was only able to see some inside layers a toyota townace fuel tank. and I believe sa bandang ilalim nga. peru hindi sa "pinaka" lalim. because when we emptied it, cleaned it and put it back with 6 liters. when we start it, the ride gives prelude to air lock signs with the 6 liters, even revving it long, on a straight surface. so we top it with additional 5 liter and then it runs fine.

so this particular ride will never run out dry. it will stall the engine with atleast a few liters still left inside the tank.

for other rides I don't know though...

and if some particles and/or few ml/drops of water happen to float, natural pwede masipsip ito mas mabuti pa ring sa gitna sumipsip/kumuha ng fuel kesa sa ibabaw. yan ang bentahe ng maraming laman.

Yes, it doesn't move but the sediments are heavier than the fluid they are suspended in so they remain at the bottom of the tank as long as there is a healthy amount of fuel in it. However, as the fuel/fluid goes down, then the system will start sucking dirt that were originally associated with the fuel at the bottom of the tank.

This is the reason I stall the Benz when I drive it below one fourth. After cleaning the filter and refuelling, I'm OK again.
