Gasoline and Methanol will both kill you. Following is some toxicology of gasoline from ATSDR CDC
Agency for Toxid Substance and Disease Registry:

Toxicological Profile
for Automotive Gasoline CAS# 8006-61-9

2.2.1 Inhalation Exposure
2.2.1.l Death
Several case reports of either accidental or intentional inhalation of gasoline vapors resulting in death
have been published (Ainsworth 1960; Boeckx et al. 1977; Poklis 1976; Wang and Irons 1961).
Inhalation of ≥5,000 ppm gasoline vapor (20,000 ppm for 5 minutes) has been shown to be lethal
(Ainsworth 1960; Wang and Irons 1961). It has been postulated that the cause of death following
inhalation of high concentrations of gasoline vapors is either central nervous system depression due to
asphyxia leading to respiratory failure, or cardiac sensitization to circulating catecholamines leading to
a fatal arrhythmia (Poklis 1976). . . .

Oral Exposure
2.2.2.1 Death
Accidental or intentional ingestion of large quantities of gasoline can cause death in humans
(Camevale et al. 1983). The lethal ingested dose of gasoline has been estimated to be 12 ounces
(350 g, or 5 g/kg for a 70-kg individual) (Anonymous 1989). The cause of death following ingestion
of gasoline is either severe chemical pneumonitis resulting from the aspiration of gasoline that leads to
asphyxiation, central nervous system depression leading to respiratory failure, or cardiac sensitization
to circulating catecholamines resulting in the occurrence of fatal arrhythmias (EPA 1987a).
The acute oral LD50 in rats for gasoline has been reported to be 14,063 mg/kg (Beck et al. 1983;
Vemot et al. 1990). No treatment-related deaths were reported in a 4-week study in rats administered
up to 2,000 mg/kg/day by gavage (Halder et al. 1985), but a few treatment-related deaths were seen in
another study in which rats were administered 500 mg/kg/day API PS-6 by gavage (Borriston Labs
1985). The basis for this discrepancy between studies is not known. No information is available on
death in experimental animals following chronic oral exposure to gasoline.
