350g of gasoline (for a 70kg person) is a huge amount to accidentally ingest. That's an LD50 of 5g per kilo, which to put into perspective isn't really that toxic compared to ethanol which has an LD50 of about 7g per kilo.

Highly refined gasoline that you can buy in pharmacies as mineral oil is safe to put on babies skin. It's not toxic in the order of magnitude that Tetraethyl-lead is.
