Fuel Question

Anyone have experience running 90 Octane Non Ethanol? Looking for thoughts.....

 

You'll probably pickup 1-2 more mpg with the ethanol free fuel. Not sure if that's worth the cost difference in your area though.

 

do it - when recently passing through Wyoming many stations offered 90 octane non ethanol. I would run it every day of the week if available where I live. Better mileage than corn blend and truck seemed to run better. I run 91 corn blend which the provider's modify for summer and winter blend. Winter blend is shit and mpg always goes down 1-2 mpg. Summer mpg city/local street is 19.

 

If the price is right do it.

 

ya I ran that up in MN while on vacation and all the way home through WI as KWI trip has non ethanol

it runs much better and MPG was up as well.

but , now Im back in shitty IL and we get corn crap no matter what

 

We have 87 corn blend and 91 non-ethanol here. All I run is the 91.

 

I have been running 89 octane ethanol free gas for several months now. I've noticed a 1-2 mpg difference over ethanol blended fuel. Also, pure gas seems to have more power.

 

Where I live in Florida, I have the option of 90 Ethanol free or 93 with 10% Ethanol. I can't bring myself to run just regular 87 octane gas. Cost aside, given the option between the two, is the consensus 90 Ethanol free is the better choice?

 

89 ethanol free here gave me 2.5mpg increase. Truck runs great. Getting 19.3mpg on my current tank. Crazy for a 5.7 4wd CM

 

Been using 87 since getting the truck. Besides few mpgs increase what’s the benefit ? If not tuned

 

run 87 + 10% eth in our tundra and 2014 4runner.

stats for the 2023 tundra. we dont baby it and we run remote start during the winters which kills the avg by a lot. also its the wife daily driver and 95-100% city driving (depends if she goes see the grandson)

 

If the new Tundra ECM has octane learning built in then it will adjust the engine timing to be less retarded with higher octane fuel.

 

You think it’s why these new engines are failing? Cause they are retarded ?

 

Depends on where you are located. Ontario area has the most E0 stations, however Quebec has none. Use pure-gas.org to search in your state/region.

 

Would y'all run ethanol free even if it isn't "Top Tier" certified?
