What kind of oil should I be using in a 49 Ford F-1 with 48,000 original miles on it.

If you ask ten different people, you will probably get ten different answers! I personally use Pennzoil SAE 30, API Service SN with an additive. The reason I use a straight 30 weight detergent oil is that, in my experience, the 20 weight and thinner oils seem to always find ways to leak. The modern oils with API Service ratings of SN or higher do not contain the proper additives for the older engines. To make up for this I use Red Line Engine Oil Break-In Additive which contains the proper additives to reduce engine wear in older (pre-roller valve lifter/cam follower) engines. The recommended amount of this additive per oil change of 4 to 6 quarts is 8 ounces.

You need and oil with zink to protect a flat tappet cam! No zink, you'll wear that cam out real quick!! Since the feds took it out a few years back you can buy a zink additive, but it is easier, and fool proof, to just use one with the zink in it. The best is 20 /50 Valvoline Racing oil. And here's a good tip, from a guy that was not only a mechanic, but has been fooling around with cars for almost 60 years-if most round trips are less than 10 miles, change oil every thousand miles on these older cars ( 3,000 newer cars), round trips over 10 miles, change it at 2,000 miles. (6,000 newer cars) Reason? Round trips of less than 10 miles don't get the system hot enough, nor are long enough, to burn the water and acids the are created at a cold start to burn out of the oil.
