[Healeys] car cover advice

[Oudesluys]

No, unless you have a very high compression engine, and even than. If 
you can get high octane leaded petrol it would be much more effective 
than octane boosters. Perhaps available from army, aviation, racing sources.
The whole thing about converted cylinder heads with hardened seats when 
lead free petrol was introduced now shows to be totally unnecessary and 
has earned the industry billions. Only in very few occasions there has 
been excessive wear of the valve seats.
If your car runs OK on unleaded (no pinking) and there is no discernible 
wear of the valve seats (reduced valve clearances) there is absolutely 
no reason to use octane boosters or high octane petrol for that matter.
