Fuel filling & oil question

[adetuono]

Anyone else have problems filling up their 2005 onwards model? It's just taken me 15 minutes to squirt 6 gallons in. I only stopped then because:-

1) the pump timed out
2) there was a queue of cars behind me

Only had the car a week, but the first couple of times it's not been a problem, despite using the same garage.


One other question; I can't seem to find any 5w-20 oil locally. Would 5w-30 Mobil 1 be OK, or should I keep looking?

They all have the fueling problem, unless you are lucky to get the fuel tank replaced. This is on warranty and some have reported that the problem is still there.
Mine seemed okay until my local Tesco changed to new pumps. Someone on another forum mentioned fueling with the pipe at approx. 1 o'clock, pointing downwards....works a treat.

As for oil, I have no idea. It gets sorted at service.

5w20 is an unusual grade but you can get it mail order from places in the UK - I did a quick google and found some. It's usually better to stick to the recommended grade.

B. Put the filling in AT 3 O'clock.
good luck

That must be where I was going wrong. This was at about 09.15 hrs.

Firstly, here is the reason why it's hard to fill. Fuel comes into the tank on the left via the filller and overflows into the tank on the right. Pressure in the right tank is relieved by a tube that runs up and round and back into the tank. Effectively, the problem is too much pressure and over-sensitive nozzles.

Fuel stations vary widely. Some you can spend all day at. In the end, TOTAL fuel stations seem to have less sensitive nozzles. I've been timed out at Tescos pumps when I pressed "Pay At Kiosk". Last weekend it brimmed without a breath when I used the card to pay. There are many tips which may or may not work with your car - filling it cold, filling it a quarter full, nozzles at 3pm, 4pm, nozzles barely in the filler....you'll find your own way but mainly find a station without prematurely sensitive shut-offs on the nozzles.

LuS1fer,

Not having had a chance to get underneath yet, I'm assuming that your picture shows the propshaft from behind and running forwards, with the tank straddling the prop? If that is the case, I'm thinking that you'd need to fill the left tank fully before it overflows into the right tank, or have I got the wrong idea? That being the case, I imagine that a larger bore vent/relief pipe might help reduce back-pressure.

Spot on. It's effectively a saddlebag effect. The modification to the 2006 Mustang and retro-fit tanks did fit a bigger vent but some say it works and some say it's no better. It doesn't really matter how big you make the vent if the saddlebag constriction stems the flow and because of emissions, that vent pipe has to go back into the tank. As my memory has faded, I'm not entirely sure but I would think it has to go back into the filler neck pushing pressure up the filler and cutting off the nozzle. I'll have to check that one on my handy "photos under the car" album. LOL.

The tank-fill issue is secondary to the effort Ford put into locating the weight of the fuel tank well forward rather then hanging it out the back like they used to do showing evidence that they really spent some time on making these cars handle properly.

Swernis advise is the same as I am giving all my customers but as lusifer says there are many different ways to sort this problem. If you find a "good " pump use it when you can. Best of luck.

pal of mine just got an 05(to replace his C5 vette which lost a fight with the armco), he puts the gun in upside down which seems to work better

I have experienced this problem. But ever since I've been filling up with BP Ultimate, it hasn't been a problem. Their pumps must be different. Occasionally it clicks early using BP's pumps. But 99% of the time it fills up perfectly.

Looks like the best plan is to try different garages then. Only problem for me is I use a company fuelcard, and it's only accepted at Texaco, which, by coincidence, is 200 yards from my house. Still, it takes 20 minutes to fill anyway, so probably worth driving the extra 5 miles to the next-closest.

One up-side of the time spent at the pump is the amount of conversations you can have with total strangers. I can't believe the amount of interest the Mustang generates. Every time I stop, someone asks questions about it. Everyone from schoolkids, chavved-up Nova drivers, housewives, reps and old 'uns. I never had such a level of interest with the 'Vette.

I experienced the same thing. I'm not sure people really recognise what a Vette is so say the usual stupid comments about gas guzzlers. Everyone recognises trhe Mustang instantly though, even though it has no badges (just a pony). I had two illegals stroking the car's paintwork once as I spent 20 minutes trying to fill at a Shell station. Sometimes different pumps in the same station are worth trying.

Just found this on a US forum; the last couple of sentences seem to make sense.

Slow fill is considered normal after 4/05 production dates. Here is what you can do to help:
Your filler neck is a rubber hose that comes off the body and is clamped to a metal tube that then goes to the fuel tank. There is a retaining bracket that holds the metal tube to the body. Loosen this bracket and pull down on the tube as much as possible to reduce the amount of uphill climb the fuel has to take. Tighten the bracket to maintain new position. This will accumulate some slack on the rubber hose. Loosen the hose clamp and slide the rubber hose further onto the metal tube. Tighten the hose clamp. I would say there is about a 50-60% success rate with this proceedure. It will likely not eliminate the slow fill completely (remember, its normal) but it may help. There are many reasons why the slow fill happens and tank design is only part of it. BTW, try not to refuel until your tank is near empty. The fuel has to cross over from the driver's side to passenger side during a fill. The pump drains the passenger side before it drains the driver's side, so obviously it will be more difficult to fuel if the driver's side is already full. In other words, it will slow fill more with 1/2 tank or more.

Worth a try, anyway.

try this site http://ratstangrestoration.com/tech.h there is a cure for those who have the annoying filling problem.
i havent tried it myself as the filling problem hasnt developed with my car yet.
hope this helps

Save yourself the trouble. I took mine apart and it was totally clear ergo has nothing to do with the fill problem. A question of 2+2=5
