...ok, I have thought about posting this earlier but after reading Pauls response in regards to another question I had asked ( he described about only using the proper fluid that is called for) but thought I should post it as a new thread.
I believe in my '76 Cadillac with a 500 that I can use either 10w/30 or
10w/40. Well, before starting my engine the other week for the first time in a few years we had to add 5 quarts of oil as due to a leaking washer on the drain plug (now repaired) nearly all the engine oil had drained out over time. My brother had on hand 5 quarts of Quaker State 20w/50 and that is what we put in. HE insists that being that the car is older that 20w/50 is ALL I should use and that it will not hurt the engine and it will help with worn parts. My odometer reads about 54,000 miles on the car but not sure how many HOURS are on the engine.
What are thoughts about using 20w/50?? any big deal or not??
