Hi, I have a Honda Jazz 2008 Gli 1.3 GE (MY09).

When I bought it (used), I used to always use Shell V-Power 98 on it. But I started travelling longer distances lately, so I switched to Shell E10 because I thought it was more economical. I measured the fuel economy between 98 and E10 and they are very similar, ranging from 12-13L/100km in my use case. I confirmed that the car is compatible with E10 from the owner's manual, and also from the sticker on the fuel door.

Owner's manual aside, is it good to use E10 on a Honda Jazz? Will it not have a detrimental effect on the engine or fuel system if I use it for the long-term? Has anyone been using it long-term on their Jazz?

 

I would not put corn into a motor vehicle. In the US, everybody tries to avoid this but the government stuffs it down (most of) our throats.

 

You'll be alright.

 

The car was designed to handle up to E15 with no side effects, apart from lower fuel economy because ethanol doesn't contain the same amount of energy per cubic unit that regular fuel does.

Speaking of fuel, there isn't any point in running anything other than the regular grade stuff. Your car just pulls timing when running higher grade, you wont see any benefit to running it other than paying more for fuel.

 

"Pull"?

Isn't "pull" usually in reference to when a lower octane fuel used? Literally, the engine detects knock (85 oct/reg), pulls timing advance from max of 55 to something like 25 or even 0.

 

in the UK we are going to E10 in september 2021 from E5 and i looked and my 2018 jazz can take it but they seem to want to go to E20 by 2030 in europe which we cant use so hopefully that wont come in

how much of a car that can use E10 has to be changed to use E20?

im my manual it says E5 and E10 maximum not even E15 so how much ethanol do you guys in the US have as a maximum ?

 

There have been serious efforts to get the corn out of US fuel. But even the big oil & car manufacturer lobbies got steamrolled by the GMO biotec & corn lobbies.

 

It's political. Iowa is a big corn state and the first state to vote to choose presidential candidates, so it's rare that a candidate will say anything against ethanol, even though in 2021 it's stupid (we have plenty of oil).

 

Green energy's the future!

Personally, I dont like ethanol. Its hydrophilic: Ethanol is an interesting molecule. It is polar or hydrophilic (water-loving) due to the presence of the terminal hydroxyl group, so it dissolves in water. Yet because of the 2 carbon chain, it has a bit of non-polar character. -sites.duke.edu

It develops algae when left to sit, even in a fuel tank. So even if a system is designed without rubbers or plastics that are sensitive to it, I prefer to avoid it. It's to my understanding the most cost effective way to raise the octane (knock resistance) of fuel, and so it's pretty important. You don't have to drill to get corn and I mean, who enjoys increased fuel prices? With today's high-efficiency engines we do need knock prevention! But again, if left to sit it develops goop that can clog injectors. Think of pushing mucus through a fine mesh screen 😂 So I avoid it completely for things like lawn mowers, and have found myself with lawn tools that start on the first or second pull after spending winter in a shed (or equivalent). Maybe the ethanol you get in the UK has some fancy chemicals in it to prevent such issues!

hehehe. Green$

Of course, all the fertilizer used to grow the GMO corn requires massive amounts of natural gas. The fracking business provides cheap natural gas and cheap fertilizer so you can see how this works. . .
