I've noticed that fuel seems to be more and more sensitive about its age.
Recently I had a few issues on my Citroen DS I was waiting to have repaired. This meant that by the time I had that done, the fuel in the tank was from March.
Now I have it back I have been using it for errands around the suburb as allowed. It wasn't running badly, but not that great either. I just put in a new tank of 98 yesterday, and what a difference. It's like a different car.
The DS motor is not a high performance unit by any means. Its an iron block pushrod four cylinder that doesn't particularly like to rev (more about torque). Dual throat weber carby on top.
I've noticed this on my E-Type as well. That motor also hates fuel that is older than this sort of age. But that motor being DOHC hemi head, 9:1 compression and the series 1 E-Types run with fairly advanced timing. Misfires horribly if the fuel is too old.
I haven't noticed the issue as much on the Mercedes, but will keep an eye on it.
