E10 fuel, and other aberrations
Posted: Mon Jun 14, 2021 4:30 pm
I can't find any discussion of this topic in the forums, which surprises me.
E10 fuel was introduced last year. I understand all standard fuel at the pumps is now E10 with the higher octane options (97 or 99) remaining at E5 spec.
This is fuel beyond the ken of engineers in the 1970s and is basically damaging to fuel systems of older vehicles - like your Zed! My flatsides got horribly gummed up when left for a while.
I'm no chemist, so I'm asking for advice. I've been told the (what used to be Castrol) Valvemaster Plus fuel additive, originally designed to replace the loss of leaded petrol in the last century (not an issue for your Zed engine), has now been modified to alleviate the high ethanol E10 fuel.
So my question is, does anyone understand the details? Anyone got experience using it over the long term? Do you recommend it? I've just started adding it at every refuel and, while it doesn't seem to have any adverse effect, I wonder if it's actually beneficial?
This is an issue for all of us!
