1997 civic dx, 137,000 miles.
1. I was told that I will run into problems if a switch from conventional to synthetic at this mileage, is that true? The car has a history with conventional oil, and currently with synthetic blend. (valvoline)
2. Is it true that a person shouldn't switch oil due to "metal memory?" I always thought this was nonsense.
3. As for oil, what brand should I use? A friend of mine swears by valvoline synthetic blend for some reason, but I used to use castrol in my previous civic and it worked great. My car doesn't like super tech conventional. It seems like a cheap oil to me, am I wrong? It thins out quickly and doesn't feel like it's protecting/reducing friction. (it could be my imagination)
