Why?? I have a friend pushing me to go synthetic in my 7.3.

BTW Amsoil does not leak the way regular synthetics do. But looking at around $100 to do an oil change.

Re: Synthetic or Conventional?

This is just like the gun lube threads I see on my other forum. No consensus, no convincing and everybody has the magic formula.

As for me, I'm not sure it matters much. Never found any tangible benefits to either. Cost is definitely a drawback to synthetics though. Some engines require it because they run so hot. If they don't require it then I usually recommend just synthetic blends or conventional.

Your truck, run whatever blows your hair back.

We need this as a sticky. Blunt and I like it. Every often we get the same thread about what type of oil to run bla bla. I guess they didn’t search. All the threads saying the same chit. Kinda like the thread “how much can my truck really tow b/c all other threads are similar but don’t quite fit my situation” lol.
