Replying to: liaison (Feb 26, 2005 9:27 am) With that in mind, you might want to use upgrade fuel above 87 octane (91 maybe) if you plan to pull a trailer, load the car to the max, climb in the mountains or just want a little more power from the car in normal driving. It makes a difference in most cases regardless of the model year. You will not hurt the car or void the warranty by using regular. My '99 used mostly regular... it did fine. My '03 XL runs better on 89 octane and gets better mileage so I use 89 most of the time. Hope this helps. Others may join in but I think you will get the same basic answer. Enjoy your Avalon....great cars.

Replying to: liaison (Feb 26, 2005 9:27 am) I talked to my dealer about this also when I noticed premium fuel noted on the specs on the car. The 05 is 280 Horsepower w/ 91 Octane. The loss of Hp going to regular or mid-grade is 5 (per the dealer). They also suggested to use every 4th tank of Premium & the rest could be Regular & I'd be fine. I used Premium 93 Octane on the first fill up & will use 89 Octane on the next three. I hope this helps. |

Replying to: fin (Feb 26, 2005 12:22 pm) That being said, I use Amoco Ultimate fuel, which is also the cleanest burning fuel around. A friend who worked in a government fuel testing lab told me he would never buy anything else regardless of what the manual calls for. The pump handle even has a plastic window in most stations so you can see that the fuel is crystal clear. If you care about your car more than about the 20 cents per gallon (that's less than a 10% premium), use Amoco Ultimate (also sold at BP stations)...

Replying to: kg4dkf (Jun 22, 2006 10:59 am) Your car apparently was driven on cheap gas and the octane rating was probably the lowest available. Lower priced fuels have less of the additive that prevents carbon buildup. ALL fuel has the minimum additive standard set by the govt. ANY premium fuel from a name brand will help clean the engine as it contains more cleaning additives. Amoco is one of the best. Cheap fuel is no bargain, long term, as you suggest. But mid-grade from a name brand is fine. Enjoy your Avalon, great cars... |

I recently purchased a 2002 Avalon XLS, 29K miles, from a Toyota dealer with a certified used car certificate. The FUEL RANGE GUAGE on the information area of the dash read 260 miles and the fuel guage itself was at the 3/4 mark when I filled with gas for the first time. I topped the tank and the fuel gauage went just beyond the full mark and the FUEL RANGE GUAGE read 210 miles. What gives??? Shouldn't my fuel range be greater than 210? Shouldn't the number be about 370, the total after multiplying 18.5 gallon capacity times about 20 mpg? How can my fuel range be 260 miles with 3/4 tank and then drop to 210 miles with a full tank? |

Is anyone using regular unleaded to drive his/her Avalon? I would like to know if the car runs fine with regular unleaded? Thanks much

Replying to: lazarous (Aug 23, 2005 3:59 pm) The new 2005 will drop more power on 87 octane as it has more power built into the engine. And it gains more if you upgrade. Going to 91 or more does nothing for the '04 and older but has benefits for the '05. Your warranty is good, regardless. But, why put cheap gas in a nice car...? Go 89 (or more) and enjoy it.

Replying to: fin (Aug 23, 2005 5:58 pm) Next year to replace my timing belt, water pump, and 2 other belts. What is your take on replacing the timing belt tensioner as well. It is an $78 part, and not sure if it goes that often. Can you tell me if you know or if anyone knows if this is usually replaced with the timing belt service. Thanks. abfisch

Replying to: abfisch (Aug 25, 2005 7:35 am) This project is not easy or cheap, even DIY. How much does another $78 really mean these days? If you change the timing belt at 60k or 90k miles and leave the tensioner in place, you are asking the tensioner to go 120k or even 180k miles before replacing it at the next belt change. Hmmmmmm ?? To cover themselves, Toyota dealers mention this part replacement when they perform this type service, but will generally do what the customer says, unless they see a failed tensioner. I have never had a belt replaced, but if you order racing timing belts (DIY) most of them come with a new tensioner too. All things considered...money, possible roadside failures, time, etc.... spend the $78. The thing might last 150k miles. But why not enjoy driving with a lowered risk of problems.
