I use Super Unleaded, either 92-93 octane, I forget

 

Ditto on the hi-test.

 

I asked the dealer if I can put regular and he said yes. Toyota also said that the engine can run on regular. I havce tried all 3 ratings here in Miami. I found no difference in MPG between the octanes. The only difference that I sense is that the exhaust noise is a bit louder on regular then on the higher octanes. Just my 2 cents. Be ready to be bombarded by everyone regarding this topic.

 

Dude I have been running regular and getting 16 mpg. No bueno am switching over to premium to see if i get the mpg that they said on sticker. IF i do i did the math and it will be like getting 2 extra gallons out of my tank for another $3.20 at the pump...

 

91 Octane.

 

The dealer didn't say "boo" about the gas.

I use 92 octane. In the big picture of things, it isn't that much more than 87. If I felt the need to pinch the pennies to that extent I would have bought a Yaris. Or maybe a '95 Geo Metro.

 

Just picked up my rig. Drove from Spokane Washington to St. Helens Oregon (386 miles). The first tank was from the dealer ( I assume it was regular unleaded) and we averaged 21.2 mpg. Filled up with high test and still am waiting to run through it to get the results.

I agree. The price difference is only about 4 bucks a tank. Doesn't bother me.

 

Dealership told me anything 87 and up. I have run all grades with no difference in performance and no knocking.

 

Dealer said "It was ok to use regular unleaded."
What I think the dealer meant "We filled your first tank with regular" ;-)

Anyway I use 91 or 94 octane (Usually 91 but last tank the 91 octane pump was broken).

 

I use the premium as recommended. It's not the fuel mileage that's in question here but the longevity of the engine. This engine was designed to run on premium. A lower octane will cause pinging and detonation. Now you won't hear the pinging because the knock sensor will hear it before you do and retard your timing.

I would never believe a salesman at a dealership when it comes to a topic like this.

92-93 octane

 

I'm using 93, you'll paid $3 or $4 more each time you fill up the tank, i think it's better for the engine.

 

Dealer said Reg was OK, but I'm using Premo just because I remember the engine knocks in the 70's and have used premo since then.

Now that's the truth!

 

Using the premium as recommended. In the long run, we know we will be glad we did.

 

Rocking the mid-grade just so nobody can say "I told you so" down the road.

My instincts prevent premium, but make me seriously consider regular anyhow...

 

87 or 89, depending on the gas station. But "midgrade".

 

91 for mine...

 

The dealer filled it with regular and it's drank regular only since. No complaints. I hope you guys don't say I told you so if I have problems @ 100K miles!

 

Premium

I am averaging from 19.9 to 21.4 MPG mixed highway and city traffic.

 

I ran premium on my FJ 80 for 14 1/2 years and 173k miles; never had a minutes trouble with the engine. My new FJ gets the good stuff.

 

I use Premium (91) and the guy selling me the car insisted that it didn't require premium fuel, but when I called the service department for a specialized mechanic on the question, he said to use premium. How many of you guys would trust a dealer over a Toyota specialized mechanic?

Also, I averaged that by using Premium, you really only end up spending .002 more because you are driving more miles per fill-up. I can upload my chart if you guys don't believe me...

 

I running regular now - testing the mileage. When I'm done with this tank I'll switch back to premium and see if the mileage changes.

Dude your car is brand new..Wait a little more the MPG will get a litte better. I use all kinds of octane in my tank, 87, 89, 91, 92..... It always cost me the same $40.....can not tell the diffference in performance...
