Ethanol fuel and the RV8
What is ethanol, where does it come from, why do we have to use it, are the myths true, what might be affected on a classic car like an RV8, what can or must we do, and where can we get replacement parts like fuel hose and clips? These were the key questions Nic Houslip covered in his talk at the V8 Anniversary Day held on 18th May 2013 for MGV8 enthusiasts.

Ethanol fuel and the MGBGTV8
The talk by Tony Lake aimed to bust some of the E10 myths with data, look at why ethanol is used in motor fuel, discuss alternative fuel hose materials and clamps, review water and ethanol issues and look at some bench tests that have been carried out. His conclusions were: upgrade all fuel hoses to E10 compatible from fuel tank to carburettor, don't use unbranded hose, use good quality screw type hose clips, fill fuel tanks to the brim for seasonal layups and share experiences with ethanol fuel on classic cars.

Conclusion: changing the fuel hoses now, rather than waiting for E10 to become available, is worth doing
Encouraging feedback from the V8 members who attended the talks on the topical subject of E10 fuel and MGV8s at the V8 Anniversary Day indicates they felt Nic and Tony focused on the real issues of concern for a classic car owner and their talks were useful. Nic Houslip reflected after the event saying "I think it was well worthwhile doing the presentations and it was clear from the responses of the audience that we had hit home, which is particularly rewarding to the presenter. Tony Lake (the other presenter on the E10 topic) and I discussed the E10 situation just before we left and came to the conclusion that the review of E10 on MGV8s made at the V8 Anniversary Day is the starting point and that we should maintain communication between interested members to see how the matter progresses. Notwithstanding that, I think it might be worthwhile suggesting, particularly to MGBV8 members that changing the fuel hoses now, rather than waiting for E10 to become available, is a good thing on cars which can be up to 40 years old and have not had a change of fuel hose."
