Replying to: autowrite (Sep 07, 2007 12:47 pm) What handbook are you looking at? I have a 2007 Sienna and can't seem to find this information you apparently found. My owner's manual says regular and does not even mention premium.

Replying to: allez (Sep 09, 2007 4:03 am) "OCTANE RATING Select Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, use premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher. Use of unleaded gasoline with an octane rating or research octane number lower than stated above will cause persistent heavy knocking. If it is severe, this will lead to engine damage." (end of quote) To Locate this information, look at the index at the back of the Sienna's Owner's Manual in the "F" section to locate "Fuel information" (page 510 of 2006 Sienna Owner's Manual). I have used 85 octane (high altitude) most of the time except when driving below altitude 2,000 feet when I use 91 octane to bring average above 87...and then refill with 87. I have NEVER heard engine knock on my 2006 Sienna. Overall average is 24.8 MPG at 17,603 miles since purchase. Recent 215 mile round trip yielded 31.7 MPG ( 215.2 miles divided by 6.799 gallons. Filled at same pump before and after trip.)

Replying to: hause7 (Sep 09, 2007 10:23 am)  Could you quote the page number in the 2007 Sienna Owner's Manual where it says the engine uses regular with no disclaimer than better performance will not be achieved with premium fuel?

Well i know it uses regular because it's in consumer guide. I would check your 2007 Sienna's owner's manuel. I have found errors in Consumers Guide. |
