Re: Fuel Tank Level & Fuel Pump Life ?

and whos they? just someones opinion, a fp is a consumable a wearable part they arent designed to last forever. at some stage they need replacing. just for your information a fueltank usually is baffled and has an area where the fuelpump resides that incases the fuel supply. do what you will at the end of the day it may or may not help your cause, ownership and parts replacement is a roulette you just never know.

Speaking for myself, even if it didn't matter in regards to the life of the fuel pump, it doesn't take the application of many brain cells, to always be riding around on empty. Where is the advantage or reward? It's always the same people who do it. I've got a 26 gallon tank in my vehicle. Why would I continually ride around with 4 gallons in it?

Forget your fuel pump. All you vapor lockers be thankful you don't have to drive on the German Autobahn.

Re: Fuel Tank Level & Fuel Pump Life ?

ok so why would you always ride around with 26 gallons full? oh wait you already explained that lol. the dte is an indicator of fuel left in your tank i would say the idea is as an indicator to let you know and plan when you may want to refill. something we never had back in the dark ages. not argueing with you we all grew up in different errors with technologies constantly changing, its up to the individual to keep up and believe these changes to be forever making our lives easier and parts becoming made out of materials that in some cases last longer and in others they are a throw away item. i think your ideals and beliefs have been beaten to death in this thread. hope your sort it all out.

Nothing to "sort out". I'm just trying to understand the foolish logic, along with the complete lack of common sense being employed here. So... You ride around on fumes because you have the "technology" to do so??? I'm still not getting this, along with the process of savoring the ability of making it to the station with a 1/2 pint in the tank. Do you get some kind of warm and fuzzy feeling when you manage to accomplish this?

Since the invention of the automobile, cars had gas gauges that let people know when they were getting close to empty. Evidently now, that's not close enough, because we've got the "technology" to ride it down to the last few remaining drops.

And for what it's worth, back in 1985, 30 years ago in "The Dark Ages", I had a Kawasaki Voyager motorcycle that had: 1.) An 8-1/2 gallon fuel tank.... 2.) A fuel gauge..... 3.) A "low fuel" warning light..... 4.) A reserve switch on the tank. 5.) A computer that read current MPG, as well as "miles to empty". I still never got below 1/4 of a tank. Then, just as now, there was no reward in doing it. As opposed to the risk of having to push a 850 pound motorcycle, because I wanted to see just how far the then, "new technology" would take me.

Here you are correct. I'm having great difficulty in "sorting out" how it now costs more to have todays "new technology" transmissions serviced, than it did to have it's predecessor rebuilt.

I'm failing to grasp how a plastic, "throw away" transmission oil pan that costs $300.00, along with $45.00 a quart fluid that you need at least $450.00 worth of, is an "advancement" over a $4.00 gasket, a $12.00 filter, and $2.50 a quart fluid. This regardless of how much I try to, "keep up and believe" how all of this is somehow making my life easier.

agree with you on that and I have always done rigorous maintenance on cars especially the trans but in this case instead of paying thousands over the life of the car in trans fluid changes, play it their way. under normal use they state it is fill for life no changes needed so by not changing it you are not doing anything wrong. So if it fails they put a new trans in under maxcare warranty and you pay $100 instead of thousands in trans fluid changes. will it be that easy when it fails who knows but they are making some pretty bold statements when they go as far as to say "Routine fluid and filter changes are not required" which is a quote from the owners manual. I know goes contrary to my care for cars also but that was before they started gouging us at $45 a quart.

Not saying that this is what I will do but just food for thought

Except I question the accuracy of that statement.

Is there any documented proof the pump itself needs to be cooled by the fuel? Obviously running it dry is bad since all liquid pumps rely on liguid being pumped to avoid overheating, but I question the assertion that the pump will overheat if not submerged in it.

The idea that taking long trips means having to stop fill up with 6 gallons (or close to 150 miles) left in the tank to protect the pump would be a terrible design.

Gas rewards.

People get them for shopping and get an accumulated discount. By the time the fuel light comes on, they could have built up a 20, 30 or even 50 cents per gallon discount.

Further, by letting the tank get more empty, you can apply the discount to more gallons. If you're only putting 3/4 of a tank or less in, you some of the savings.

While certainly there are people that often ride around with only a few gallons in the tank (usually people who put in whatever they can scratch together at the time), that's not what most people are doing.

What most people I know do is fill the tank, then drive until light comes on (which is well above "E"), then go get more. Nobody likes spending time at the gas station, so the less often, the better.

Further, it's easier to calculate MPG on cars without that data if you do a full fill each time.

Finally, using most of the fuel in the tank ensures a fuel, fresh tank full each fill up. With more ethanol being put in gas, that's very important since ethanol absorbs water and goes bad faster.

It's not like most drive all the time with a near empty tank; it's that they let it get there before filling up.

I still say, the only real reason to not let your tank fall below a 1/4 tank is to avoid running out completely when you can't get to a gas station when you planned.

Re: Fuel Tank Level & Fuel Pump Life ?

I'm the same way Silvermax. I've always maintained my vehicles religiously, because it was both affordable, and the smart thing to do. This is no longer the case. With the new ZF 8-Speed you're looking at $300.00 for the pan / filter combination, along with approx. $450.00 worth of fluid. Let's say you can pull this off for just $100.00 in labor, (which I doubt at any dealer today).

You're still looking at over $850.00 to simply service the transmission. As you stated, you're actually better off just driving the thing until it fails under Max Care, then have it towed in, and the entire unit replaced. And just pray to God this doesn't happen in the middle of nowhere, or when you're on vacation.

So we've gone from transmissions that could be serviced for under $100.00 and rebuilt for $825.00. (The price a transmission shop quoted me to rebuild my 1991 Ford 4-Speed Automatic Overdrive). All the way to $850.00 for the same service, and $4,000.00+ to replace it on a ZF 8-Speed unit.

The downside to all of this "lifetime" nonsense, is we as consumers have no way of knowing how long this so called "lifetime" is? If I'm pulling my boat across the desert with 140,000 miles on the clock, all with original fluid sealed into it's "lifetime" transmission, is that when it's "lifetime" will come to an end?

At least with regular service you had at least some knowledge of the condition of the internals, as your vehicle advanced in age and mileage. Now, you just have to hope. As I said, I'm having difficulty adjusting to how any of this is "better"?
