I ran a 1970 MGB GT for 8 years day in day out, snow, sleet, rain, highways
& byways, on unleaded and it did not suffer at all. The engine was not
"rebuilt" when I bought it and when I sold it the engine was as strong as ever
I also tested unleaded on my rebuilt engine in a 1967 Austin Healey for
Shell (all expenses paid for a year!!) They made special measuring things
to determine "recession". There was none after 3,000 miles
My take is that for less than racing, using unleaded will not be a
problem, In Canada we have had unleaded for years and I have yet to hear
of any Brit classic suffering. If you race, then you may have a problem -
but other things will be evident before valve seat recession! One thing I
do believe is that shoving in "additives" definitely results in one thing -
it makes the manufacturers richer!!
