The minimum octane rating gasoline that should be used in my vehicle

genxer36 · 04-09-2009, 01:20 AM

Taken from the Toyota website

You can find the recommended fuel octane rating for your vehicle on the back cover of your Owner's Manual.

Our "current model" year vehicles have the following unleaded fuel octane rating recommendations:

MODEL OCTANE

4Runner - 87

Avalon - 87*

Camry
4 Cylinder/Hybrid - 87
V6 - 87

Corolla - 87

FJ Cruiser - 91

Highlander
V6/Hybrid - 87

Land Cruiser - 87

Matrix - 87

Prius - 87

RAV4
4 Cylinder - 87
V6 - 87

Sequoia - 87

Sienna - 87

Solara
4 Cylinder - 87
V6 - 87*

Tacoma
4 Cylinder - 87
V6 - 87

Tundra - 87

Yaris - 87

* For improved vehicle performance, the use of premium unleaded gasoline with an octane rating of 91 or higher is recommended.

Why would an FJ Cruiser require 91? It has the same 4.0L as the tacoma.

Here is that same question with some answers..
http://www.thecarconnection.com/answ...premium-gaswtf
and these guys are pretty split between the octanes...
http://www.fjcruiserforums.com/forum...o-you-run.html

from Toyota.com
FJ- 4.0-liter DOHC 24-valve SFI VVT-i V6; 239 hp @ 5200 rpm; 278 lb.-ft. @ 3700 rpm
Tacoma-4.0-liter DOHC EFI V6 with VVT-i; 236 hp @ 5200 rpm; 266 lb.-ft. @ 4000 rpm

I don't know what any of that means, so what is the difference??

EFI vs SFI electronice fuel injection vs sequential fuel injection. seems odd to me though, why use different fuel delivery for same motor. does seem to add a few hp and a couple pounds of tourque in the FJ's case.

The Tacoma 1GR-FE does have the same engine and fuel delivery system as the FJ. In many owners manuals (mine for example) it says to use 91 or higher for best performance. Why its listed as "EFI" and "SFI" on the Fj is beyond me.

Most engine computers will detune the engine to prevent knock. So there is a chance that you might see better performance or better mileage with higher octane gas. The question is, is the mileage gain more than the price difference? For my 6-cyls, I got 10% more mileage, so I bought mid-grade gas if it was not 10% over Regular in price.

You will be fine.

I have to plead a whole lot of ignorance here.

What about any octane with ethanol? Do 1gr's like or care about ethanol?

TIA

Owner's manual for the 09s says it's not a problem. As a general rule, less ethanol preferred.

I was filling up at a place today that claimed to have 100% gasoline no ethanol. It mentioned all kinds of bad things, like it would cause water to be more of an issue with ethanol fuels, paint damage, etc... . I try to avoid anything more than E10.

Thanks

To clarify: Owner's manual says nothing E10 and less is a problem. I was assuming we weren't talking about substandard gas.
