<VV> lead additive

[Bill Elliott]

Lower compression engines like the 80/95 can often run fine on low 
octane fuel and will gain no benefit from running higher octane (but 
they don't actually "prefer" either)... with higher compression engines 
it's a matter of necessity (to protect against preignition/detonation), 
not really preference.
