[Healeys] Gasoline

I would not worry with the old barges we have as long as the octane 
rating is OK. Get any petrol you like. Where I live (NL) petrol is 
delivered by two refineries to trucks of all oil brands, the major being 
Shell, Texaco, BP, Esso and a few smaller brands. These all may or may 
not add the so called specific dopes. Very often the same dopes are used 
for more than one brand or all brands. One truck load may provide petrol 
to stations of several brands.
Also if you take samples from various (high volume) petrol stations of 
one and the same brand, these samples are hardly ever identical or even 
with the same station a week later the fomulae would be different.
There is no way of knowing.
There is one advise though: get petrol from a high volume station.

To complicate matters, I just received notice from both Audi and Porsche 
recommending only "Top Tier" gasolines. Apparently the regulations that 
determined how much detergent had to be added to gasoline to be 
considered "premium" has changed. Most gas has only about one fourth of 
the previous amount which is leading to clogged injectors in some cars. 
Google top tier gasoline for more info. Only a few "brand"names qualify 
including Shell and Chevron. Probably little effect on a needle and seat 
cars but food for thought. Jim Brown
