Is the world doomed when oil runs out?

Before mineral oil was discovered we were hunting whales to extinction for their oil to use in lamps. Ironically, the oil industry did more to save the whale than any green organisation ever did.

Also, the Diesel engine was originally designed to run on vegetable oil and modern ones can easily be adapted.

Also synthetic oils can be made from coal and other hydrocarbon feedstocks.

YEP. back to the cave man days

SYNTHETIC Oil is the BEST and PENNZOIL ULTRA is abut the BEST there is! it is made from NATURAL GAS and NOT from CRUDE OIL or WAX or ASH like VALVOLINE is.  With PENNZOIL you get a warranty to 500,000 miles! there is NOTHING like it and it KEEPS SENSORS and the INSIDE of the  engines CLEAN as SHOWROOM after the FIRST USAGE!  THERE were MILLIONS and MILLIONS of dinosaurs for MILLIONS and MILLOINS of years and they are BURIED under us! CANADA used to be at the EQUATOR millions of years ago before MAN was even thought of! The CONTINENTS formed from TECTONIC PLATES that STILL separate EVERY YEAR! The COAST of AFRICA fits into the COAST of SOUTH AMERICA as swell! SOON there will be a GLUT of cars when the NEWEST QUANTUM GLASS batteries are RELEASED! They last FOR NEARLY EVER and charge quickly like in FIVE MINUTES or so! The ANIMALS of AUSTRALIS are TOTALY DIFFERETN from ALL other animals! They are MARSUPIAL ONES! ANY WAYS there wil ALWAYS it seems be OIL and GAS out there! it SEEMS impossible but seems TRUE!  AND NEW sources appear all the TIME from ALGAE dying off an other ANIMALs dying off and getting BURIED

Horses never needed oil. So there is that.

is it , when will we run out , cars and buses run on gas too , and electric cars ..Stop trying to be a troll .

If people like you keep asking stupid questions then yes

Only the human part of the world will be affected. The rest of nature will thrive. One animal on this planet is dependent on oil.

The world will NEVER run out of oil.

There is enough to last more than 1,000 years in the US alone.

No...we'll grind up all the liberals and turn them into oil. The way things are going with our schools we'll likely have an endless supply. 

No I use Castrol Edge 100% Synthetic
