#5619 of 5876 How to Find a Good AURORA?
Aug 08, 2005 (9:22 am)
I really like the Aurora, and I'm sad that the Oldsmobile line is no more. Anyway, in my area, it is hard to find a used Aurora-private party sales are for cars 7-10 years old, with very high (>90K) miles. Did Olds ever sell the Aurora to rental car companies?
Also, should I avoid the 4.0 liter engine? Did Olds manage to fix most of the problems by 2002?
In short, how do i find a decnt Aurora, and what price (off bluebook) should i be prepared to offer?
#5620 of 5876 dipstick level
Aug 08, 2005 (12:16 pm)
I went to jiffylube today to do my first oil change. The oil had gone well below and was at the "ADD" line...
The guy at the shop, used 9 quart to fill it up as the dipstick level was still low (much below MAX line) after he had put in 7 1/2 quarts...
I could not convince the guy that car needs only 7 1/2 quart according to the manual as he was saying that with that much oil the dipstick was not getting at the normal level...
Now am concerned that the engine may have oil over the level required and possibly damage the engine.
Have anyone heard about a "bug" in the dipstick lenght or the position/angle that it gets thru the bottom of the engine?
How dangerous is to put more oil than required? Should I take some out?

The dipsticks for the Classics are known to show the wrong level. I have never seen any information on a corrected dipstick being available. I think the correct amount to add is 8 qts. with filter change. That's what it takes to get the oil level to 1/2 qt low on my '97. That is where I maintain the oil level -- 1/2 qt low.
I do not think the extra qt will harm your engine. Someone correct me if I am wrong. What I have always read is that the crankshaft will splash the oil around, causing more oil into the cylinders where it will burn off. I admit that I have never really understood how this works.
The other problem with the dipstick is that it is almost impossible to get consistent, repeatable readings. I never check oil level until the engine has been off at least 1/2 hour, and I always park in the same place in my garage (slight uphill slope). The tip of the dipstick touches the oil surface at a shallow angle, causing the oil to "mark" the dipstick at different places top and bottom. So I always rotate the dipstick 360 degrees and pull it out quickly. This has helped some to get repeatable readings, but it is definitely the most difficult car I have ever owned in this regard. Labor of love.

That makes me feel a litle better and stop alarming.

Too much oil = very bad.
There are a number of things that can go wrong from overfilling. While there is too much oil in the engine, high pressure can develop in the crankcase, you can get oil leakage through the oil pan gasket and other engine seals (I suspect my dealer putting 9 quarts into my Aurora - discovered the next day after driving home -contributed to my rear crankshaft seals failing on my '98). You might have reduced gas mileage while the oil level was too high - it's possible that the crankshaft was splashing in the oil, which made it work harder. And that splashing could cause the oil to foam up, which could cause the oil pressure in the crankcase to drop, potentially leading to premature engine wear or even damage. Best to take it in there and make them drain and refill it with 7 1/2 quarts. Ignore the dipstick, it plain sucks.

There may have been some 2001-2003's in rental fleets. I never saw a Classic in rental.
I would stick with a '98 or '99 if you are looking for a Classic, or a 2002 or 2003 if you are looking for a new Aurora. The 4.0 is actually a superior engine - its Northstar brothers are used in a lot more applications than the 3.5.
How to find a good one? Search eBay, cars.com, autotrader, et. al. and get a feel for the market. Hard to find a Classic under 70-80k these days, frankly. If you find one, try to get maintenance records. Get the GM service history (need the VIN and a friendly GM dealer). Have a mechanic inspect the car.
Hope this helps,

Too much oil can result in the crankshaft "beating" the oil into something like whipped cream. This bubbly oil will not lubricate properly. I think that 8 quarts was the amount of oil to mostly fill the crankcase with a filter change. So, 9 qts is probably not enough to cause damage, but who knows.
checked my owner manual (Seville), which says 7.5 quarts with filter...

Thanks for correcting me about high oil level.

I, ASAP, went to the shop and had them drain all the oil for 20 minutes
Then they put 7 1/2 on it.
The guy that worked today in the car knew what was doing and understood my frustration.
I don't know how much problem was caused for the time that I drove the car with 9 quart of oil inside but was only 2-3 city miles of driving...I don't know if this makes a difference or not
Hope that short mileage the engine did not pressurize all that oil..
I will keep my fingers crossed but if something happen i'm going after them, kept the original receipt which inidicates that thay put more that 9 quart of oill in the car
