Premium (93 Octane) will allow a 2001 Aurora V8 to run at maximum power. Lower octane fuels will produce less power because the PCM will retard the spark to prevent knock, and that will lead to a noticeable drop in power....up to 10% less.
Unlike the previous year 2000 model that required Premium fuel, the 2001 Aurora V6 & V8 both can run on Regular.
The firing order on the 2001 Oldsmobile Aurora V8 is 1-2-7-3-4-5-6-8, according to page 6-674 of the 2001 Aurora factory manual.
Aurora 4.0 V8 takes 7 litres of oil.
It's under the intake manifold. Remove that & the starter is accessible.

You never have to. They have magic forever plugs and run on baby smiles.

Have your Torque Converter/ Lockout Swith checked. I would also be worth it to have cam timing sensor checked. I had this exact problem on my 01 Aurora V8. Replaced sensor. Haven't had a problem since.
91 octane or higher
AnswerFrom 1995 to 1999 model years a 250hp 4.0L Northstar V8 was the only engine option. In 2001 and 2002 with the new body style a 215hp 3.5L V6 was offered along with the 4.0L V8 and in 2003 only the 4.0L V8 was offered. On the back of the car on the trunk under the licence plate, It will say "Aurora 3.5 or Aurora 4.0." This obviously indicates the size of the engine, you jackass.
