Good service from ExactUk. Glad you're back on the road again.
Being an American product, I'm surprised it failed so soon due to ethanol corrosion. It presumably was designed to operate in US gasoline, which contains more ethanol than ours (usually up to 10% and even 15% is available). Although suppliers are now permitted to add up to 10% here, no one yet does so and 5% is the maximum content at the moment.
If you're worried, stick to Esso Synergy Supreme+, which is still ethanol-free.
