Is there an oil additive to get oil pressure up on old engine?

Oil pressure isn't really a function of the oil. There are several things that could make you have low oil pressure, but they're pretty much all mechanical defects in the engine itself, and adding stuff to the oil won't help because the oil itself isn't the problem.

Low oil pressure in a 1995 oldmobile aurora?
ck oil pressure with gauge, if ok replace oil sending unit there is also a $20.00 dollars oil pressure sensor that sits underneath the engine by the oil pan area(front), this sensor can get old and display the wrong pressure in the system.
What psi of oil pressure is suggested on a 350 engine at idle and cruising speed?
If everything is working properly, the oil pressure will be controlled by a "bypass" valve inside the engine. Once the oil pump builds enough pressure, any additional volume is "dumped" back into the crankcase so that the oil lines don't build up too much pressure and damage the bearings and oil pump.When the engine is cold, you should see the MAXIMUM oil pressure. Start the engine, watch the oil pressure and see where it goes. The needle will rise rapidly until the bypass valve starts dumping excess oil. Wherever the needle stops, that's your normal oil pressure. Usually it's somewhere in the middle of the gauge, 40 to 60 psi, but the exact number isn't critical. What's important is keeping it in that range... wherever the bypass takes over. If the engine warms up and the oil pressure starts to go down, you have worn bearings. That's the most common reason for a loss of oil pressure in the 350 engine. It's a great old engine, as tough as they get. If the oil pressure is starting to go down when the engine is warm, just change to a heavier grade oil at your next oil change. If you've been using 5W15, change to 10W30 or even heavier. That will help you get a lot more life out of the engine. The thicker oil will keep the worn bearings lubricated better and help the engine last longer.
Oil pressure dropped dramatically on my 1997 ford expedition is it the oil pump?
Yes, Change the oil pump... If the oil pump stopped working, severe engine damage is likely. A new/ rebuilt engine may be necessary. The only way to tell for sure is to tear down and inspect the old engine.
How much oil pressure should a 1982 Chevy 350 have?
The old rule of thumb used to be 10 lbs per 1000 rpms. So, if that old Chevy small block engine is warmed up and idling with 10 lbs of oil pressure, don't worry about it.
Where should the oil pressure for a warm 3800 v6 engine sit?
Generally for every 1000 RPM you should have 10 PSI oil pressure. Before I would get alarmed, I would replace the oil switch for you gauge as these can give you a false low reading when they are old.
Why does the oil pressure light come on when the engine idles but turn off the instant you hit the gas?
oil pressure is created by the oil pump, which is driven mechanically as the engine turns, and the faster it revs the harder it pumps. It should deliver enough pressure at idle for the light to stay off. Your problem is either a worn oil pump or your oil is too thin and needs changing. If you have an old engine, put in a heavier oil. Penrite 50 is good. Hi another possibility is your idle is set too low Also, you could have a bad or weak pressure release valve in your oil pump. (AKA bypass valve). In addition, if the oil has not been changed in a long time the oil filter may be filled with sludge reducing the pressure. Changing the oil and filter first to heavier oil is a good first step. Your engine bearings may be worn and letting too much oil escape, resulting in low pressure when the oil pump is running slower (when the engine is running at idle). Revving the engine too high can cause damage to the rod bearings and allow oil to escape too easily. If your engine has a lot of miles on it, or if it has been run without changing the oil regularly, your engine will have a lot of wear. The oil pump, main bearings, rod bearings, and camshaft bearings may all have a lot of wear on them allowing the oil to easily escape without allowing pressure to build up. Rebuilding your engine may be needed. But try changing the oil pump first.
What kind of oil should you use in your 91 sentra?
you should use 10W-30 of any reputable brand of oil. With a car that old, I would also add an oil additive like Slick 50 or similar for older engines. They cost a lot, but definitely keep your engine running smoothly.
Why would your oil pressure in a 1997 Jeep Cherokee drop to almost 0 when the Jeep is warm and ideling?
This may indicate you need to put a higher weight of oil in the engine. Or the oil in the engine is old and has thinned. jeeps don't actually hold much pressure under idle when they are warm if your check gauge light isn't coming on then you have no worries
What causes a ticking noise after the car first starts then goes away?
The engine parts are rubbing until the engine oil pressure builds up and the oil starts to lube the parts. Old oil, wrong viscosity, or a clogged filter can cause this to be worse than necessary.
Old ford E350 engine runs high oil pressure?
Either you're very lucky and should enjoy it or you have a bad sensor or gage.
Can an old engine use synthetic oil?
No, old oil can use synthetic engines
How do you replace the low oil sensor in a 97 Saturn 1.9 liter?
Do you actually mean "low oil LEVEL", or do you mean, "low oil PRESSURE" sensor?The low oil pressure sensor screws into the side of the engine. Just disconnect the wires then using an appropriate wrench, screw out the old one and put in a new one.However...Unless you're just replacing a leaking oil pressure sensor, they seldom fail. If the low oil pressure light is coming on when the engine is idling, but goes off when the engine is at operating speed, you MOST LIKELY have worn bearings.If you have worn bearings, try running a thicker oil in the engine. You may be able to get quite a bit more use out of an engine if you switch from the recommended 5 W 15 oil to something like 15 W 40.
