oil burn?
 
So i went out for start up yesterday and the oil level light came on then went away, go out and check and its at the add 1 qt mark. I have put quite a few miles on since the last change, so is this normal?

1 quart per oil change is about right on a high mileage car. Check around the valve covers to see if there's any seeping. This is a common place to loose oil. Also, look under the car. Peek at the bolts holding the oil pan on. The pan gasket also starts to leak over time.

Will do, thank you for the speedy response

didnt see any leaking out of the gaskets but when i pulled the cap off i noticed some yellow gunk collected around the cap

Makes me think you need a new PCV valve. Oil usage can increase if pressure builds inside the crankcase. When you pull the oil cap off with the engine running, is there a smoky vapor coming out the hole readily?

Yep, check that PCV.

Thats what I thought too but a bit bigger problem now, I put 1 qt of castrol high milage synthetic blend in and also a can of 6cyl engine restore, I was driving around and noticed my pressure dropped badly, not moving much past 40lb, could my sending unit have gotten gummed up from the engine restore or did i add too much to the engine?

The engine restore is the silver can with the soda can style pop top, supposed to lubricate the crankcase and restore compression and all that good stuff. Made by Restore

Not trying to be clever but did you put the recommended weight oil in?.
