Hi all. This isn’t really a Q, more just an A.

Looks like putting my car into storage won’t be happening next year but it’s still a possibility after that. One worry I had was regarding fuel breaking down and causing damage to the fuel system components and someone mentioned a product called Aspen 4 to me. It’s a clean fuel that doesn’t break down as quickly as normal petrol and doesn’t separate in the same way. I got in touch with the company who make it and they said that although I could use Aspen 4 they wouldn’t recommend it but they did make a fuel that was perfect for long term storage. The text for the email is below. Just thought it may be handy if any of you find a year crops up when you have to take your car off the road.

“Hi Pete,

Thanks for your email, whilst aspen wont damage rubber parts or corrode metal like regular petrol when left over time, it can have negative effects on seals which have gotten damaged over time on regular petrol.

Whilst it is rare for this reaction to cause a problem, it is not worth the risk for us to recommend using it in expensive vehicles like your Ferrari.

Our company does however sell another product which does exactly what you are looking for. It is based very much on alkylate fuel (the main component of Aspen) but it contains aromatics which keep the rubber parts of the fuel system swollen to avoid the risk of leaks.

You can purchase this online and more information can be found on our website.


if you are going to store the car for a few years without use, it may also be a good idea to use an oil which contains a storage additive designed to keep engines free of rust from moisture build up.

Any of the driven oils in the “HR” range have this additive as well as much higher levels of zddp anti wear additives which are lost in modern oils.


Let me know if you have any further questions“
