Premium gasoline

I have heard that they never need to be replaced and that article makes sense as to where they have mounted it. I have also read that they should be changed every 30,000 miles. I'd like to know what the truth is. I guess I'll call a guy I know that was a Toyota mechanic for 25 years and find out for sure. I'll also call my local dealer since they seem to be pretty honest. They have already talked me out of buying parts for preventative maintenance that I thought I needed by saying, "You don't need that. It's good for the life of the vehicle".

 

As the article said for the last 30+ years toyota has not included mention of changing the fuel filter in the maintenance section. Why believe the change ever 30K nonsense.

 

BMW switched to "lifetime fill" on their transmissions in the late 1990s, when they went from DexIII to ESSO spec fluids, similar to the WS ATF on Toyotas. They still have maintenance procedures for servicing the transmission of course. You see, 'lifetime' to a manufacturer refers to the leasable life of the car where the dealer may be on the hook for maintenance. After 3-4 years, the manufacturer, or dealer, does not care whether the car falls apart or not. By then its time for you to buy a new model.

If there was such thing as a lifetime filter, there would not be such a huge availability of OEM and aftermarket replacements for it. Perfect example are the ring gears in your differentials. You guys swap ratios out and occasionally break the teeth off, needing replacement. But those are 'lifetime parts', and you cant just pull replacements from any dealer shelf.

 

I've never owned a Toyota before. The Haynes manual I have says every 60,000 miles but then that is why I don't really trust Haynes or Chilton. I guess people just make this stuff up as they go along without consulting the company that made the vehicle. I guess my spare fuel filter will be laying around in a box for a long time because I'm not going to wrestle that old one out if I don't need to.

 

I see you're point. In other words, what is the lifetime of a given vehicle? The definition could be different depending on who you talk to and their reasoning. In other words, it might not be a bad idea to change you're fuel filter around 250,000 miles or maybe at 100,000 considering most of these trucks routinely go 250-300,000.

 

The article I linked called it the 1 million kilometer filter, 620,000 miles, if that helps.

 

I changed my fuel filter at 200,000 miles on my 3.4V6 that is located inside the frame rail and good thing I did cause when it came out it was pouring out fuel that looked a dirty rusty color. It was the original Denso brand filter and I replaced it with the factory OEM filter. I now have 236,734 miles on it and don't plan changing it for awhile. I won't wait 200,000 miles though, that's for sure!

 

i changed my fuel filter about 2 weeks ago at 241k and it had 40k+ on it... there was so much difference in weight between the old filter and the new one i installed that i took it and weighed it. 98.7 grams difference between the 2. same brand same part #.

on a side note that i'm not sure is related my check engine light went out (p0420 code) last monday and hasnt come back on since and am showing only the stored code on my reader...

i will change every 30k from here out- its worth the $23 and 10 min. easy wrenching to me...

 

there was no fuel in it as i weighed it the next day after it sat on end overnight and there was no drips or sloshing turned any direction. that weight difference is all dirt.

 

If I have this right you think you captured almost 4 ounces of dirt with your filter in 40K+ miles? Weigh out 4 ounces of dirt and try to fit that in your filter.

Find a new gas station.

 

Its all a ploy by Big Filter to consolidate their shadow government.

 

87 octane drips out my tail pipe and I only get 365 kms to a 80 litre tank.

91 premium has no ethanol and I get 560+ kms to an 80 litre tank. Costs maybe an extra $8 to a tank.

No pinging, no hesitation. no bullshit.

Done.

 

Not shiting you. It's true.

 

It is water dripping out of your exhaust, it's a product of combustion. Not even possible it was gasoline dripping from your exhaust.

A 35% reduction in mpg between 87 and 91 is preposterous. Try 87 again.

 

It is not preposterous. It is a fact. I live at about 150 meters asl.

I know it's not fuel pissing out the tail pipe, but the ethanol in the 87 octane seamed to attract more moisture than necessary and the tail pipe appeared to be having a really good beer piss when I used it. The truck runs like shit on 87.

It runs like a top on 91 octane.

 

4 oz does sound like a lot... im going to cut it open and take a look.

 

I don't believe you can physically fit 4oz of dirt in the prefiltered side of a filter, maybe if you tap it in with a tool.

I changed mine in my first taco when i was doing an engine swap, saw where it was located and went to the parts store. Very easy swap when the engine is out, looks really difficult once in.


And if the person above has fuel dripping out of his exhaust, waaaay bigger concerns than octane. Nothing like leaving a trail of fire everywhere you go.
