|
|
Hello All,
Following a meeting of our DLOC club recently, one of our members brought up some articles he had researched about the new bio-fuel content of todays petrol. It seems it has a more acidic nature and can damage fuel system components in older cars. At present the content may only be 1-2% but this is set to rise and normal petrols will gradually disapear. It may be necessary for the classisc car user to find non-bio content fuels as some components of the systems may not be replaceable with modern materials that are not prone to damage. Talk is rife of increased costs for non-bio fuels.
It is also noted that bio fuels are less efficient than petrol so you use more per mile and in older cars this is more prevalent.
You might like to look at some of the stuff out on the web:

The main concern will be attacking rubber gaskets and the potential for corrosion on tanks and alloys. Anyone else with an interest in this would like tou hear your thoughts. |

I wonder if we could just do a litmus test and add a small amount of alkali to neutralise it?

Shell came out with a document on this about a year back but I can't find it at the moment. If I do I'll post it. You are recommended to fill the car to the brim before wintering because the ethanol based fuels are hygroscopic and add a non alcohol based fuel stabiliser (as used in boats). Also, I didn't know that there are two types of ethanol based fuel - summer and winter - and that winter fuel, delivered to fuel stations from 15th October onwards and which has a higher volatility, is apparently best for laying up so now is the time to fill up.
PS This might shed some light though:-

I believe Winter and Summer blending of petrol has been practiced by the oil companies all my lifetime.
The link above is very interesting. I have heard claims that ethanol can soften plastic components such as hoses and pipes and some carburetter parts made of plastic, but I have never heard of the possible effects on rubber or metal corrosion. I was aware of its hygroscopic properties, but mistakenly it seems, I thought that would safeguard against water accumulation in tanks and carbs. _________________ Quote from my late Dad:- You only need a woman and a car and you have all the problems you

Another potential problem with this, if you have lining material within the tanks it can decompose it which means orrible stuff floating around in your fuel. A very difficult problem to erradicate.
We could all do with knowing more about this. If you attend a club might be helpful to raise issue and see if anyone else has more knowledge. |
