Tetraethyl lead was historically the most effective anti-knocking agent in gasoline, but due to environmental and health concerns, it has been mostly phased out. Today, modern additives like methylcyclopentadienyl manganese tricarbonyl (MMT) or ethanol are commonly used as anti-knocking agents in fuel.
tetraethy lead
'Gasoline' has the potential to ignite too early ('detonate') in high compression combustion engines, producing a 'knocking' or 'ping' effect. The first compound discovered to remedy this effect was tetraethyllead (tetra-ethyl-lead, TEL). This anti-knocking agent therefore came into widespread use in petroleum, but use of this chemical began to be phased out after the toxicity of lead became known. Thus other antiknock agents used instead of tetraethyllead are: ferrocene, iron pentacarbonyl, toluene, MMT (an organomagnesium compound) and several others.

simethecone and other non-foaming detergents are good anti-foaming agents.
It is a fine chemical powder which will absorb moisture and clump. The anti-caking agent helps prevent this.
