What gas are you pouring in your 16?

It does not burn slower. It has a higher flash point and can sustain higher compression and heat without igniting.

 

Ethanol is bad on hoses, pumps, and fittings. It destroys plastics. Newer cars are made to endure ethanol's terrible side

 

I know nothing about 2016 tacomas, but i can tell you that in my offroad truck, 87 to 91 octane gas makes the world of a difference.

 

+1. 3 octane points can cost me 10-15* of timing on the track and .3-.4
ET

 

91 ftw

 

Wrong. The ECU ONLY monitors knock and does not adjust anything unless it senses pre ignition. However if one puts 87 in a vehicle designed for 91 the ECU WILL try to compensate because the vehicle is likely to knock causing the ECU to do it's job, Without a tune higher octane is a waste of money. (Perhaps even with a tune) The ECU ONLY detects knock situations and compensates

Show me where higher octane in a vehicle designed to run 87 changes the ECU setting to gain more power or MPGS..or all that extra power LOL..I'll wait.

But it's your money to waste on a fairy tale

I agree with you. I think most have a perception that burning "cleaner" or more efficiently equals "more power". Nope. If your vehicle manual says to run 87, then why run anything else. The manufacturer has already told you what the vehicle is designed for. But most people think they are better engineers and know of unknown secrets by running 91 octane.

 

Thank you.....The fairy tale that an engine designed for 87 will suddenly tune itself to run stronger with better fuel economy if one puts 91 in it is silly.

Hell why not out 93 in it and get 5 more HP and 4 more MPGS. LOL ECU monitors knock, not octane.

 

not in Texas. Ethanol is used as an octane boost and suspect it is not just Texas. There is station in east Texas that sells ethanol free but in regular grade only for that reason. I am running milled heads on my Mercury so if I want ethanol free I have add an octane booster.

 

Here in Colorado 85 is sold in place of 87 as the starting grade - we get 85/87/89 at the pumps - supposedly to adjust for the altitude and lack of O2. In my '04 Tundra I put 200k on it and tested it many times - I got better mileage with 85 than anything higher and never had any fuel issues at all. Same in my motorcycles. Now, I will say that we used to get ethanol in our gas only in winter and it was always accompanied by a big drop in MPG when it hit the pumps or a corresponding boost in MPG when it left for the summer. Sadly that is no longer the case and the EPA is trying to force 15% ethanol on us soon.

 

We have a few non ethanol stations. I don't run that in our vehicles. But i do load up about 15 gallons in containers every Spring to run the lawn tractor and gas power tools.

 

EPA is trying but their are a lot of folks fighting it. With the republicans in charge I do not see it passing. If the democrats were to win back congress then all bets are off.

 

Actually I don't think the EPA is trying to mandate 15% ethanol, its the farming lobbyists. Anyone who might consider themselves an "environmentalist" already knows that ethanol is worse for the environment (and the economy) than regular gas.

 

Silly stubborn old man, the 2nd gen 1GR-FE engine is designed to run on 91 octane optimally but can still use 87 octane which reduces power a bit. The 3rd gen 2GR-FKS is the same way, designed to use 91 octane but can use 87 at reduced power levels.

 

You have it backwards. the 2nd and 3rd gen Tacoma V6 engines are designed to use 91 octane but can still use 87 octane with reduce power and without any ill effects. The owners manual even says 91 octane is optimal.

 

Yep. My manual says "1GR-FE- Select Octane Rating 87 (research octane rating number 91) or higher. For improved vehicle performance, use premium unleaded gas with an octane rating of 91 (research octane number 96) or higher. " I can tell the sluggish performance with regular, but not between Plus and Primo. That's why I run plus 89 most of the time as a compromise.

 

Theres no mention in here about the role that compression plays in higher octane /combustion, I know back in the day we'd run our street rides with either 93 oct. from union 76 for engines with 10.5:1 or 103 octane (or AV fuel) from Gulf stations for engines with 12.5:1.... lower compression motors are fine for lower octane fuel & lower octane fuel is a disaster for high compression motors...

 

I went into an octane/compression discussion a few pages back.

 

My bad, too lazy to click backwards...

 

Okay, so what is meant by "For Improved Vehicle Performance"? Does that mean more HP, better Gas Mileage, longer life of engine and powertrain? Does that mean I can take "Dead Mans Curve" at 65 mph instead of 35 mph? What is meant by "improved performance" or is it left general like that for the operator to fill in the blank with 'what they want'?
