What octane to run

I just purchased a 2001 Tacoma with the v6. I dont have a owners manual so I post this question. What gas does this require or do you guys run? 87,89 or premium?
Thanks

 

87 is all that's required. I run premium because boost

 

If you haven't modified the factory ECM or adding boost, there is no need to run higher than 87 test. If you experience detonation with a factory engine you have other issues and higher octane fuel will only be a bandaid

 

Higher octane fuel requires more compression and is harder to ignite. Dont run anything other than 87 unless you like to waste $ and maybe get worse performance. UNLESS you have modified your engine to run a higher octane to get some type of plus out of it.

 

High octane fuel does not "require" more compression to burn and is no harder to ignite. The fuel is still atomized, and present with an ignition source will ignite regardless of compression. The key is keeping it from prematurely igniting.

 

Completely false, higher octane does require more compression and is harder to ignite (burn) the higher you go. That is why drag cars that run 120 race fuel need to spray 87 first into the cylinders to get the engine going. Once it is started it pulls the 120 from the tank a burns it. Another reason why they run rough at idle and smooth wide open along with a slight cam offset.

 

Our trucks cant take advantage of higher octane fuels. it used to be a myth that cars that didn't need higher octane fuels wouldn't benefit from it but on newer cars it is relevant. they can take advantage of that resistance to detonation with ignition timing and variable valve timing.

 

Set up an experiment to test your theory. Atomize 87 octane and then highest test gasoline you can find with a spray bottle, with ZERO compression and tell me high test fuel NEEDS highs compression.

 

E85

 

The 3.4 runs well on regular 87

 

Also very good for boosted applications

 

Yes!!

Race gas at the pump!

 

Cheaper to boot also. Amazing how much timing you can get away with utilizing E85

 

I really hope this isn't serious, but I think it is. How can people be so confident when saying utter rubbish?

 

How? Facts are facts

 

Higher octane is harder to combust and requires more compression. Do some research on fuel ratings. Went to tech school for 2 years learning this stuff.

 

Post some data to prove your "facts" or just try my simple experiment and see how it works out.

 

Man I think your tech school lied to you, or you just forgot and got things backwards. Higher test fuel simply resists spontaneous combustion due to compression. Gasoline, of any readily available octane rating does not need combustion at all to burn.

 

Putting a open flam to any flamable gas will burn...thats not what im saying. High octane gas is for high compression engines (building hp) which is why running 87 in a high end motor will make it knock. Not sure what or how you want me to prove this to you other than you doing your research on this information. Im not going to do it for you

 

Op, 87.

Everyone else, take your pissing match elsewhere.
