Hi there, I recently bought a 1997 Cuore and due to its age it’s not supposed to take E10 (10% ethanol) fuel according to the resources I’ve found. Is it true that I should be avoiding E10? If so what damage could it cause if I were to use it?
Anyone have any experience with this?
E10 will be 95 octane if like here in Australia. It will be fine on E10 and I ran my Cuore engine on it for a decade trouble free. Any issue would be with leaving it sit for long periods (like three months or more) because the ethanol is hygroscopic and will absorb water from the air’s humidity. If you keep using it the thing will be fine. E85 is an extreme example of an ethanol blend that will absorb a lot of water if left for a few weeks and anything metal can be subject to corrosion. E85 also leaves a gooey mess inside manifolds and heads.
It won’t give any engine problems. But long term it MIGHT degrade the rubber fuel lines and other rubber pieces and gaskets. Generally it won’t give any problems before the car rusts away.
[quote=“Misch, post:1, topic:7084”]…it’s not supposed to take E10…[/quote]Unless fuel in the Netherlands is different from that of her surrounding neighboring countries, if you’re not filling up with E10, the only other available fuel will be E5 (5% ethanol). They don’t print this to be visibly obvious on the pump. But, if you look closely, it’ll be stated in smaller more remote print.
There might be a chance that the more expensive higher octane variant might be alcohol-free. In neighboring Germany, this is sold at Shell stations
In the netherlands E5 might be ethanol free depending on the brand and/or location. But E10 is perfectly fine for any Daihatsu and most other cars.
It might be a bit less fuel efficient though.
So I’ll be fine if I take care of the hoses and gaskets?
[quote=“Aaron, post:5, topic:7084”]…It might be a bit less fuel efficient though…[/quote]It certainly will be less fuel efficient. Since annual fuel costs have risen, beginning this year, the discrepancy between the price of E5 and 10 has widened, making E10 more attractive to those with less expendable incomes
Not really necessary. The hoses and gaskets usually only go bad if you let it sit for very long periods of time.
I’ve had a L7 that was more efficient on E10 than on E5. Don’t ask me how, i don’t know either. It just was.
With E10 about 1:13 and with E5 about 1:9.
It was probably running a bit too rich. To obtain equal performmance with pure petrol, a higher alcohol to oxygen ratio is required
