The chemical smell used in propane is ethyl mercaptan. Cut an apple in half and leave it under the seat of the car for a couple of days. Don't forget about it or you may have 2 bad smells. The apple absorbs the odor.
The mercaptan odor has been added specifically to assist in the detection of leaks. If odor from the gas is noticed, the implication is that you have a leak. Attend to it promptly.
There must be a gas leak. Contact your gas supplier IMMEDIATELY, if the smell is in a house. If it is in a car, have your mechanic check for a leak.
No. natural propane is an odorless gas.
A gas leak.
Check for fuel leak Check or replace charcoal canister
The propane will leak out
The gas of choice used in houses for cooking is propane. This is a natural gas which doesn't have an aftersmell or odor when ignited.
Propane itself is a single compound, but the gas inside a consumer propane tank is a mixture of propane and an oderant (smelly compound) such as ethanethiol or thiophene so you can smell when there's a leak or the gas has been left on.
it could be a gas leak i would have it checked just to be safe if i were you
may be pre-cat exhaust leak.
Yes. But circumstances may not let you smell it. See related link. Not all propane has ethyl mercaptan added to it for the smell. A great deal of propane is used as a propellant in aerosols and is odor free as it is in its natural state.
You would have to use propane. If it were possible to use natural gas (methane), the car would have to be re-calibrated to use it.
