#16 of 75 How about clamping the disconnect hose by abfisch Oct 31, 2003 (7:17 am)
Nomad56:   Is the line to the filter from the tank rubber. Can you clamp it, and then change the filter without breaking my back and removing the seat and fuel pump connection.   Let me know.   A.Fisch
#17 of 75 Fuel Filter.. by nomad56 Nov 03, 2003 (9:24 am)
On my 96, it is below the master cylinder and intake. Yeah, nice and easy to get to. FYI: These are often hard to get off. Get yourself a filter wrench, or ratchet extension w/ "crow's foot" wrench. I seem to recall 14mm????? Use caution, NOT to kink any of the metal lines it is connected to. Also, if you use OEM replacement, it comes with replacement gaskets. You may want to see if these come with any aftermarket replacements. I use OEM, 'cause my buddy gets 'em for me:) -nomad56-
#18 of 75 Thanks/Fuel Filter by abfisch Nov 04, 2003 (5:40 am)
Nomad56:   Thanks. I will look below the Master. I have been forewarned twice, to use utmost caution getting it off. I have already bought the crow's foot set of wrench's from Sears. I also have the OEM I bought over the net. It comes as an entire unit with a quick disconnect on the bottom.   Think I am going to try my luck at doing the PU C.A.B. next week, then getting it realigned. Do I have to get it realigned if I replace the rear C.A.B. I think I know the answer.   Thanks for the tech advice.   abfisch
#19 of 75 re;: avalon fuel filter change by petras Jan 04, 2004 (12:29 pm)
i have a 98 avalon purchased used with about70K mi. fuel filter has never been changed and my local toyota dealer doesn't recommend it be changed unless needed due to possibility of damaging fuel line...to prolong life of fuel pump, i'd like to get filter changed, any thoughts out there? thanks
#20 of 75 Fuel filter and general maintenance by obafunque Jan 04, 2004 (1:45 pm)
I am also planning to change the fuel filter on my Avy 2000 with 72K. Since I bought the car from a dealer with no previuos maintenance information what is the best "do it yourself" kind of maintenance it will be recommended with that type of mileage? Any advise from the expert on this forum? Thanks in advance
#21 of 75 Petras-Fuel Filter-Toyota Dealership by abfisch Jan 06, 2004 (7:21 am)
Petras:   If that what the Toyota dealership told you, then it should probably send a little light off in your head. If that a nice answer or the correct answer. I am not sure of the 98 Avalon; Nomad56 has the last body style but filter need to be changed every so often and the gas in no exception. The problem is that you need to be meticulous in changing it (see repair manual) with disconnecting the negative terminal and relieving pressure in the lines. Then, you need to use a "Crow's wrench" and use caution not to strip or bend the fitting.   Buy a Hanes manual for reference and either do it yourself, or take it to someone who wants to fix/repair cars instead of just selling them.   abfisch
#22 of 75 Premium Gas Clarification by donotsolicit Jul 30, 2004 (11:13 pm)
Hi, first time caller, thanks for taking my call...ha ha... I am about to embark on a purchase of a 1998 Avy (as you Avy junkies so lovingly call it)XLS. I have looked the car over and I am quite certain this is the car for me and my family. However, in my most recent search to once again check the internet for a better deal, I came across some information on the website cars.com, and wondered if there is any truth to it. Does the Avalon XLS require Premium Unleaded Fuel? The current and only owner claims that she has never put Premium in it, and is not aware of it having needed Premium. With the cost of gas these days, and the fact that I drive 20-30 K per year for work, this would be cost prohibitive. Any Replies would be greatly appreciated, since some very hard earned cash is on the line.

#23 of 75 prem or reg by fndlyfmrflyr Jul 31, 2004 (12:31 am)
Replying to: donotsolicit (Jul 30, 2004 11:13 pm) In spite of what the fuel requirement is for the car you may find, depending on driving conditions, it may cost less per mile to use premium.   My 96 Avalon now gets a steady diet of regular and runs fine. I have noticed better mpg on trips when premium is used, but not much difference around town. The owners manual says regular, but for better performance use premium. I have not done an actual test over time to see if there is a significant difference in mpg between regular and premium for our mostly local driving.   I keep a fuel used log in my cars and recently did a test over time (more than 1500 miles of mixed driving) with my Acura. The car ran fine on regular, but got 8% better mpg on premium, more than the cost difference between regular and premium at the time of the test. In addition, using a stop watch revealed the car accelerated faster using premium (3 to 4 tenths of a second from 0-60), and felt more peppy at part throttle, but 'felt' the same when the pedal was floored.   The 8% difference is close to the almost 10% difference (prem better) I have seen on our Avalon between using regular and premium when on trips.

Replying to: donotsolicit (Jul 30, 2004 11:13 pm) I have owned a 1998 xls since it was new. The only time I have used premium and noticed a difference was on long highway trips. Even then, the milage difference was only 2-3 MPG. My advice is to just use quality regular unleaded for your everyday driving Replies to this message: fndlyfmrflyr (Aug 14, 2004 12:49 pm)
#25 of 75 Re: Premium Gas Clarification [nonfib] by fndlyfmrflyr Aug 14, 2004 (12:49 pm)
Replying to: nonfib (Aug 14, 2004 6:46 am) That 10% improvement in mpg on the highway means as the cost of gasoline continues to rise it will cost you less per mile (on trips) to use premium than to use regular (as long as the price difference doesn't get to be more than the 20 cents per gallon it is now). The added range from using premium on longs drives sometimes can eliminate the need for a fuel stop too.
