Tank Ooze

gas tank oozeAbsent any questions this month, I will share something interesting with you. Recently I drained and removed the gas tank on the Datsun 240Z project. This car was parked in 1982. I removed the drain plug, but no gas came out. I poked at the hole with a screwdriver, and felt a thick tar like substance. I poked through it and very dark, varnished gas began to dribble out.

After removing the gas tank, I stood it up on end. About a gallon of thick, black asphalt like substance oozed out the filler neck.

I googled it, and learned that gasoline literally turns back in to crude oil after sitting for a long time. After 35 years, it does not resemble gasoline anymore.
