>Can any of you guys throw some light on the issue of lead additives for
>unleaded petrol.
After a pollution tax was added to leaded petrol in Finland, leaded fuels
disappeared in few months. I have used 98/99 petrol with sodium additives
(these are added at oil refinery, and such petrol is available here at
every gas station). Now I have run my Mk 4 for three years with no problems
with exthause valves, seats or guides, neither elsewhere in the engine.
I have heard, that about 1 to 5 % of old engine types can not use petrol
with sodium additives, and a valve-seat conversion must be done. Obviously
Rootes unit is among those 99 % lucky ones.
