The recommended oil for an Oldsmobile Alero is SAE 5W-30 oil. If you live in a state that does not get freezing temperatures, 10W-30 is acceptable.
SAE 5w30
SAE 10w30 any major brand.
SAE 5W-30 any major brand conventional or synthetic oil. Use High Mileage oil if there is over 100,000 miles on the odometer.
If the engine is original, use standard oil. If the engine is new or has had a full rebuild, using synthetic oil will result in a longer life for the engine.
5w30
The type of oil one can use in a 1993 Oldsmobile Cutlass is either 10 W 30 or 20w-50. This oil can be purchased at any auto parts store.
It depends on the climate but in the summer here in KY I use 10w 30 and the winter 10w 40 in my 00 Intrigue.
