Should I drain all the gas or run it dry?

O.K., I used all the gas out of my car an I put super unleaded instead of regular, now my check engine light is on an it's still running like crappe.I have a 99 Altima GXE. Guess the shop will be next.???

Answer 1

you may have put leaded fuel in it.. some racing fuel has lead in it and can totally mess up an o2 sensor and fuel system in a modern car

Answer 2

Drain some and then put Sunoco Ultra in it. I had the same problem. It was caused by water in the gas station's tank. After I put the Sunoco in it it ran better and on the next fill up the problem was gone. If there isn't a Sunoco then use the highest octane fuel that's in your area. You could also add a can of DRY-GAS to your fuel first and then run it and see if that does the trick.

Note: Some catalytic converters are more susceptible to misfire damage than others.

Answer 3

Water in the gas can cause those kinds of problems. That happened to me once. Sometimes water can seep into underground gas storage tanks. I heard that there was something that you could add to your gas tank to absorb the water without doing any damage. Call a auto parts store. They can answer the question for you. (This is only a guess. It may not be that at all.)

Answer 4

It also depends on the make and year model of your car a lot of new cars are calibrated and set to run on regular unleaded gas not to exceed a max octane,some of these cars will not run properly on mid and super grades of fuel.

Answer 5

you got water in your gas from that gas station's gas, you can get a couple of cans or bottles of dry gas or a product called heat that will help dissipate the water in the gas.
