My car has low oil pressure. How can I fix it?

It's a 2004 Cadillac Escalade with an engine of 6.00My car has low oil pressure. How can I fix it?
Do you work on cars? Check the main and connecting rod bearing clearance. Check the oilpump. Make sure the engine has enough oil and that the engine isn't clogged with sludge. That's a lot of very hard work. Take it to the cadillac dealer and have them fix it. When the bill comes and it's enough to buy a 10 year old Corolla that still would be running without any problems, just pay it and have the Escalade cleaned and waxed so it still looks good as the corolla runs.My car has low oil pressure.

You may wish to check the oil level first off. If low on oil, filler up.
