Synthetic Motor Oils
I recently put synthetic 5W30 Mobil 1 motor oil in my 1986 Nissan 200SX, after moving from Florida to New Jersey. The car still had 20W50 regular oil in it. When the temperature dipped down low here, many people told me to get the thick oil out of the car asap and replace it with thinner oil.
My roommate had a few spare quarts of synthetic, which he gave me. I've never used synthetic oil.
The car has 113,500 miles on it--I'm the sole owner. I will be driving roughly 10 miles a day, and not every day. I'll be spending more time in the car warming it up than driving it!
Considering the age of the car, the weather, the distance, is it all right to use synthetic once in a while? Should I use synthetic year-round, upgrading to a thicker oil in warmer weather? (I won't be using 20W50 anymore, even in the summer, since my driving will be short distances at slow speeds.)
When I was in Florida, I was told synthetic isn't necessary, and to just use 20W50 year round, except possibly during the winter months, when Florida can actually dip below 65 degrees (The horror!) But Jersey? Sheesh, it's cold.
What is your opinion, given the car is 18 years old?
Thanks, everyone! Jack D.
