When the oil pressure gauge drops, you should also physically check the oil level on the dipstick to confirm that it is really low. Otherwise, it could just be that your sending unit is clogged. If you just automatically add oil and are over filling it, the excess pressure could cause other problems, like blowing out a seal. Just make sure what the problem really is.
Yeah just keep the oil full (check it very often, like at least once a week), check the transmission fluid once in a while, and the fluid in the radiator, and you'll be fine. No need to really spend much of anything to keep an old GM going, just do the basics.
I am still using my mother's 1985 Oldsmobile 98 Regency (45,000 miles). This is a great car! I have a 2009 Lexus, and while it has all the amenities, the Olds drives better.
Domestic cars will last forever. I see 70's or older domestics every day. The older GM cars are like tanks. They will go on forever.
If only we could go back to 1980, and reset! Everything has been downhill since then, and I mean a lot more than just in the automotive sense.
Reagan's election marked the break from good policy, but you're quite right, it wasn't till the 90s that the plutocrats fully controlled Congress as well. 80s and 90s were all downhill for the toiling majority, and now we can see where we are at - the masses making $10 hour, while the parasitic class complains when it has to pay 39% tax.
I am so spoiled on American cars that I never check the oil on any of mine. I just change it every 10,000 miles. Even one of my cars with 240,000 miles on it still wasn't using a drop of oil when I sold it. With that said, if there is a leak (rare with most American cars) or oil consumption due to using cheap non-synthetic oil, it is important to watch the oil light and check the oil if the light comes on. If I had a car that required checking the oil every week, I'd either sell it or rebuild the engine. I have never once checked the oil in either my 2006 or 2007 Ford. Just oil changes at 10,000 miles.
