It's possible that you have a bad spped sensor which is located on the transmisson, this would cause the speeometer to stop working and a ck engine light to go on. You would have to have a diagnostics test done to determine the engine trouble code.

SOURCE: High mileage oil change for a 1994 Nissan Pickup; what to use?
mkimdaly: There is a product on the market called "Restore" which is an oil additive designed specifically for high mileage engines with oil consumption and smoking problems. Mind you, it will not fix evey situation, but it has resolved quite a few on cars which have come through my shop. "Mechanic in a can".
If I am not mistaken, it is designed to fill in small scratches that may be in the cylinder walls. I also has an effect on lifters and on oil seals. There is also a product put out by "Lubromoly" it is a product made in Germany and you may not find it on the shelves at normal retailers, but possibly carried at repair shops which specialize in imports. I carry this product line at my shop and have had good luck with many of their other products as well. There is a company called "Worldpac" but they only sell to repair shops. The product line I am talking about, I have to buy must be bought by the case.
I am sure there may be other comparable products on the market which you may find at "OReilley's or Autozone. You need to speak to their sales people and possibly ask to talk to one of the people who are at their wholesale desk at the back who may be even more familiar with the products. FOLLOW THE INSTRUCTIONS CAREFULLY! The main reason many products don't seem to work well, is that they are not applied as the manufacturer had instructed in the can and/or box! A product as old as the hills and twice as dusty is "Marvel Mystery oil" I have used it on engines which had little or no compression and pulled the plugs, poured the oil in the cylinders and let it sit over night. I would spin the engine over in the morning to blow the oil out, screw the plugs back in and fire the engine back up. There have been many times than I have had engine regain compression because the oil freed up rings that had stuck to the pistons. This oil can be added to the motor oil and the GAS! As far as the type of oil to use in the engine: It really depends on how well you have taken care of your engine to begin with. If you have done frequent oil and filter changes and the engine is relatively clean inside, I would run a 20W-40 with the additive and in my shop, I happen to use Castrol. Although most premium oils will perform quite well. If you have an engine with a lot of sludge buildup inside it, the sludge is probably the only thing holding it together. WARNING!!!!! DO NOT USE ANY KIND OF ENGINE FLUSH DESIGNED TO CLEAN THE INTERNALS OF THE ENGINE! When I refer to this, I mean a product that instructs you to put it in, run the engine for a while, drain it and then replace the oil and filter. YOU WILL IN ALL LIKELY HOOD DO MORE HARM TO THE ENGINE THAN HELP!
I hope I have answered your question.
Good luck.
SOURCE: speedometer not working
the most likely thing is one of the gears on the trans tail shaft is worn and the cable is not being turned, pull the speedo driven (on transmission) gear out and see if it is ok, most likely the teeth are worn off.

Either the gauge is bad, the cable is kinked or the speedometer connector is bad...at the tranny.

Talked to Nissan and they said I have a bad Speed Sensor or white grear is stripped. I am going to look for it before purchasing because it is a $172.00 part. If anyone has a diagram of where to locate this sensor that would be greatly appreciated.
