I just bought a 65 F-100 with a six (See gallery). How do I tell if its a 240 or a 300??? Also, how much oil do I need for the oil change??? Also, my exaust manifold is cracked, are the 240 and 300's interchangable??? Anyone have a spare??? Thanx Mark
Since you're in Houston, and I'm in San Antonio....we share oil strategies.
We don't need 5w, when is the last time we saw -30 below?
10w is ideal for the winter.
30w is a little light when it's 100 and you're in stop and go traffic.
40w is better.
Bottom line 10w30 in the winter and 10w40 in the summer.
