Synthetic cleans engine up is definitely a good choice. Your car will probably take 5w-20 or 5w-30 which you can get at any parts store

SOURCE: I had asked about the check oil light coming on

I know nothing of a sensor in the oil pan. What you need to check is the oil pressure sending unit. The unit will look like this. 2c49e3a.png
Check the connection at the sensor to make sure it is secure before replacing. If you find it is leaking it for sure needs replacing. The unit will be located in a location like this on which is a 1995 Buick. 2a08cb5.png

How much will a tuneup for a 2004 buick La Sabra

Generally speaking, modern cars do not require "tune-ups" like older cars. There are regular maintenance tasks and wearable components that need to be replaced, but the costs vary wildly depending on the shop and the brand of parts they use. Oil change, air and fuel filters, and, every 10k miles or so, spark plugs and wires are about all that needs done unless indicated. Also, coolant change, which I do annually on all cars I own.

"SERVICE ENGINE SOON" is pissing me off

engine sensors are designed for non synthetic oils to be used and no one has bothered to update the technology for synthetic oils( program has been fixed but the hardware is old design. synthetic oils are really just recycled well filtered and rechemically balanced oil (called synthetic because they do not get the base oil directly from the ground). however their flow characteristics are similar to old oil and this can throw off a sensor read confusing the computer. if you are using synthetic oil, try an oil stabilizer, Lucas oil products has a good one, if it persists, try switching back to a non synthetic oil.

Weight oil?

I'd use 5 w 30 in cold or cool weather, then switch to 10 w 30 or, 10 w 40, when it gets hotter.
