Fuel additives

[SaphireSpud]

Hello David,
a good decision to get another Stag!
Don't waste your money on an additive - Unleaded is perfectly ok - My Stag gets treated to Momentum, or similar, because I can feel the difference! Hope to discuss this with you soon.
I am also in Cardiff and suggest you meet with the local SOC branch (they're a good bunch and very knowledgable!)
Regards, John.

I think some of the very early mark 1 heads had softer valve seats, but you won't find many of those about, even my very early mk1 engine has had mk2 heads fitted at some time in the past.
