There are technical differences, but for most purposes they mean the same thing. Take a very, very close look at your spark plug tips the next time you pull them out. Do you see tiny, tiny little dots of metal on them?

When I pulled my plugs last year that had a lot of ash and carbon deposits on them. I will pull them again this weekend to see if anything has changed.

The plugs on my F-150 look like a fudgesicle :lol:

Another question, the D-150 will burn oil somedays and then it will go for a month without burning a drop. Have any idea what is causing this.

Tough to diagnose without more info, but spark knock and oil consumption go hand in hand -- in BOTH directions.
