fj cruiser an tacoma have the same engine right?

my friend has an fj and says he has to use premium fuel??? i thought the tacoma and the fj shared the same 4.0 V6. what am i missing here?

 

Maybe we could have this one Deleted?

 

Our 4.0 is supposed to have premium fuel put in it.

 

what?

 

false

 

Toyota recommends the premium for "optimum" performance, but it's not necessary. You can run any grade you like.

 

How is this false?

 

Yeah its false. You can run what you want unless you get pinging.

 

Exactly
That's all i meant.

 

The 2010 FJ Crusier doesn't share the same engine as the Tacoma. Well same displacement, however it has Dual VVT-I, like the 2010 4runner. However they don't require premium fuel.

 

I just read an article that says they are all sharing the same engine for 2010. Not a toyota site just doing some looking about.

"
Toyota has been an innovator in the use of electronically controlled valve timing to improve the efficiency of their engines. The new version of the 4.0L V6 engine used in the Toyota FJ Cruiser for the 2010 model year is a great example.
This proven engine, shared by the Toyota Tacoma and 4Runner, is a workhorse that will deliver years of driving enjoyment in all situations. As a result owners will experience all the fun and versatility offer in the 2010 FJ in conjunction with the solid dependability that has been the foundation of Toyota's continued success in the marketplace."

 

I have four friends with FJ's. From 07 to 2010.
Till 2010 both trucks had the same engine and they, both require -premium minimum 91 fuel. In 2010 the FJ engine is different. Double VVTI. Does not require premium any more.

The Tacoma stay the same. Toyota suggest that we use premium but some guy's are using regular with out any problem.

A lot has to do with the -load, altitude and personal choice. If you don't hear any pinging ???? Your choice.

 

Perhaps for 2011? If you look at Toyota.com the specifications for the 2010 models are listed.

 

I posted an excerpt from the article in my edited post above. I hadn't noticed this post. Gone check it out.

 

09 says -premium. Looks like they made some changes.

 

Just what mine said .

87 octane is fine for the Taco unless you want to buy oil executives another 10,000 shower curtain or some such thing

 

my truck pings like a mofo with 87 octane. so i run 89

 

This is directly from the new edition of 4wheel and offroad...on the cover fj vs. jeep:

The Silver Fresco Metallic '09 Toyota FJ Cruiser in our brawl came with a 4.0L 1GR-FE 24-valve engine with variable valve timing resulting in 239 hp and 278 lb-ft of torque and requires premium 91 octane gas. The engine feeds a five-speed A750F automatic with a 3.520:1 First gear and a 0.716:1 overdrive. The transfer case is a part-time VF2A with a 2.56:1 low range.

 

^ not from toyota....

 

FJ requires 91 to get those #s guys.
