2016 Tacoma GAS! Help

okay I have shell 87 in my tank. Is it okay to but in 87 ethonal free. Like mixing it

 

Of course.

 

Agree w/ Clearwater as long as the octane is 87 you are fine. And you will have less separation issues since it's ethanol free (my preference).

 

The ethanol free gas will not make much difference for the extra cost. I tried it. You will notice some change at first but the computer will sense it also and bring the engine back the factory running conditions.

 

Here's data from the manual. I always keep a copy of this in my phone so that I can look up things. I attached it to here, it'd be good to keep around. Welcome to TW!

Use only gasoline containing up to 15% ethanol. DO NOT use any flex-fuel or gasoline that could contain more than 15% etha- nol, including from any pump labeled E30, E50, E85 (which are only some examples of fuel containing more than 15% ethanol).

DO NOT use gasoline containing more than 15% ethanol.

●If you use gasohol in your vehicle, be sure that it has an octane rating no lower than 87.
●Toyota does not recommend the use of gasoline containing methanol.

 

Also interested in this.

 

Toyota/EPA does not test for MPG using ethanol-blend; there is no national standard. Remember, "Up to 10%"
They use 91 ethanol-free.
Toyota Senior Energy Researcher, Mike McCarthy, is on record with 3% loss with E10.

 

Proof? Not doubting you. Just wondering.

 

So Marinas can sell ethanol free gas and do so at a higher price. About half of the gas I have used in my 7K miles of my truck have been E free. I can see no difference in power or mpg... I keep buying it at about .50 higher. I do think it's more important in older cars, lawn equ, riding mowers ect,

 

Also goes by, "indolene test fuel".
