After water got in the engine oil what is best to use to clean up the inside of the engine?

There is nothing that you can use to absorb the water that can get everywhere because the absorbent on the markets are not of the right viscosity to reduce friction while the engine is running. The engine has to be running to get the solution everywhere. For example WD 40 is actually water displacer. Can you use it for lube? NO, it is to light weight and too expensive, Another water absorber is alcohol (ethanol) but it is too light. The answer is to drain the oil that is present, change it and run the engine to operating temperature. This will heat everything to the boiling point of the water and it will turn to steam. Leave the engine fill cap for the oil off, and after running it for about 30 minutes, you should change the oil again. You can use diesel fuel in the oil if you want to attempt to flush any globes out that the water may have created but don't put more than 1qt of diesel fuel in the engine and make sure that the level is not too high. In other words if the engine takes 4 qts of oil, use 3 and add the diesel. Run it and 30 minutes later, drain it.

A better question: how long will synthetic engine oil protect the engine? I don't put a lot of mile on the Saab 9-3, 1999.

You need to change the oil every year or 10.000 miles. The oil will be polluted with foreign material like water, sulpur etc.

Water is mixed with oil.

Fix this ASAP, Coolant in oil will ruin bearings. Have a shop check it ASAP. I would check the intake manifold gaskets first.

What is the check gauges light

CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Engine seized no oil did not get check oil or check engine light

The oil pressure warning light only comes on when oil pressure drops below 4psi at this moment there is no oil in the engine most often it does not get to this point because oil, water etc is checked every week. It could be your engine was using oil which would point to an engine fault.
