My daughter just bought a 2002 with 50K miles on it. I know some cars incorporate a computer in the engine that detunes to compensate for lower octane fuel. In the interest of saving a dime per gallon and sacrificing some performance in a typical commuting bumper to bumper drive, can she safely do this?
Thanks.

 

You can at your own risk,I have heard of engine knocking becoming a problem after many miles doing this.....A thread was started just a while ago about a guy who did a ghetto experiment,he filled his 3rd gen with 87 octane for like 3 months said he had no problem....SEARCH IS YOUR FRiend


Oh yeah welcome to the Board,your daughter has a sweet ride

 

Yes.. some people regularly use lowest grade gas in their TL/TL-S.. It could lead to lower milage per tank as well as premature carbon build-up. I wouldn't suggest it. Welcome to the luxury car world... and Welcome to the forum!

There ya go, second post on that page. My mini-research as I traveled westbound.

And those were all technically premium, too. I can't imagine running 87 octane.

 

why not just use the octane recomended?
what is it like 2-3 bux more to fill up, wich is gunna last longer.

 

Mid grade around here is 89. It goes 87 - 89 - 93 in most stations. In my first gen, 91 octane rec., I go back and forth between 89 and 93, usually ending up with a mix that is closer to 91 then either of those are themselves, with no ill-results.

 

Do a search on the term octane on this forum, you'll find all you want,and then some.
