Marvel mystery oil....

[1936 ford pickup]

I just purchased a Quart container size of Marvel Mystery Oil.

I use it in my '36 Ford pickup mixed withy my gasoline. I use 4 oz. of Marvel Mystery Oil per 10 gallons of gasoline (per their recommendation).

Now I noticed on this container that it says you can use up to 20% of Marvel Mystery Oil in your engine.

That would mean 1 Quart of Marvel Mystery Oil and 4 Quarts of oil.

Is anyone doing this to their flathead V8's.

Just curious....

THANKS, Bruce in California
