Question about 2003 BMW 5 Series

3 Answers

Bad Gas? I think I got some bad gasoline and now the car misses a lot. I want to change the oil filter but don't know where it is. Any other suggestions would be great since I'm a single girl and can't afford the stealership prices and of course my warranty is 10K out. Thanks.

    Yes, SES light came on, took it to AutoZone and they said code was spark plug, had plugs changed and mechanic said it was code for "running lean" thought fuel filter may need changed or bad gas. Does this help, can't remember the number to the codes he said.

How can you tell if you have bad gas in your tank


What are the indications of bad gasoline?
A:

QUICK ANSWER

The symptoms of bad gas involve a lean misfire, which creates a P0300 code in newer cars, engine detonation and pinging, sputtering and stalling. These occur because the bad gas fails to keep the fuel system clean and introduces contaminants that can clog fuel filters, fuel pumps and fuel injectors. In addition, bad gas can have an octane rating lower than advertised, leading to the aforementioned detonation and pinging.

FULL ANSWER

Receiving bad gas from a fueling station is more common than the industry admits. The only cure for fixing bad gas is to drain the fuel tank and fill it with fresh gasoline while cleaning the fuel system in the process. Bad gas can be caused by gasoline suppliers not mixing the required amount of additives in the fuel, causing them to be less effective in preventing deposits and causing fuel varnish to form in the fueling system. Sometimes the tanks, whether at the fueling stations tanks or in the vehicle's own fuel tanks, are contaminated with dirt, corrosion and water. Because no filtration system is absolutely perfect, even with the various filters and stringent EPA requirements in place, these contaminants end up inside the car and may damage it. Gasoline that is lower in octane often occurs because either the supplier or the fueling station intentionally sells regular fuel as higher octane, profiting over the difference in price.

I have a 2011 red renegade moped. as I was driving to work it jut quit running like it ran out of gas, but had plenty of gas in it can anyone help me?


Check gas filter might be clogged I wouldn't be surprise if it was, lots of bad gas out there, usually near the carburetor or near gas tank. best place to look also check air filter if it a sponge filter clean it with gasoline use gloves of course before handling gasoline, or some form of cleaner then after cleaning that try it. but I would bet it the gas filter. good luck

I think you got hold of a batch of stale gasoline, have seen it many times. This happens this time of year because they are using up all the winter blend gas so they can switch to the summer blend..

My car is toyota revo sport runner ,2.0 gasoline engine automatic, model 2001, I consume 1ltr per 6 km in city driving ,is this normal? just give me some tips to save fuel.


Make sure your tires are inflated to the proper amount.
Change your air filter.
change the oil.
Take your car into the shop and get a tune up.
Don't fill up unless you are on empty, since all the gas weighs a lot
Clean out your car- as mentioned above extra weight = more fuel consumption.
Consider turning off the air conditioner and rolling down the windows instead. However at speeds of over 80kmh the use of AC is better for fuel economy than an open window.
Don't top off because when you do the fuel will evaporate in a hot environment through the gas cap seal.
Don't drive aggressively
These are just a few tips that i could think off of the top of my head. Hope this helps. Good luck.

The fuel filter is in the gas tank with the fuel pump - it's actually a 'SOCK' that filters fuel before it enters the pump. Odds are it's not the filter. Odds are you have a Throttle Position Sensor which is going bad (bad spots in the potentiometer). Erratic resistance changes sending BAD signals to the Engine Control Module and Transmission Control Module ECU & TCM. A good technician knows how to check it with an analog ohm meter.

Dumps raw gas into engine


Just a few things to check. Take off the fuel filter and make sure there is no water in it. If you have put in different spark plugs than AC Delco, then change them to AC Delco. If you haven't looked at the plugs or the fuel filter, then it is way past time to replace the filter and new AC Delco spark plugs only. These places that insist that you use Bosch plugs or split fire plugs don't know ****. The Delco plugs are made especially for your engine and will out last those cheap non-working Bosch plugs.
If the fuel filter and plugs don't fix it, make sure your air filter intake isn't stopped up with a bird's nest. Happens a lot. If it still misses after new plugs, you may have a fuel injector sticking.
The bad smoke is the gas-thinned oil passing the rings and unburnt fuel smoke. The missing really bad is most likely fuel soaked spark plugs. Make sure you change the oil while changing the plugs or you will have a redo. Let us know if any of this helps. Dale
