Introduction

I've been adding 2 cycle oil to my diesel fuel for the last about 20,000+ miles. So far I've found out that it has improved a few things like engine noise is reduced, fuel mileage increased slightly, and knowing the the fuel system is being lubricated is always a plus!

I've been adding a quart every time I fill up with fuel. So if I pump 20-25 gallons I'll add a quart of 2 cycle oil. It makes it roughly 80:1 to 120:1 ratio of fuel to 2 cycle oil. This is relatively low ratio and with not cause any harm engine as far as I known.

There is another reason why I'm adding 2 cycle oil to my fuel. It because of EPA changing the sulfur levels in the diesel fuel. This will reduce the lubricity. Knowing that VP44 injection pumps are a touchy subject you might as well add oil to the fuel.
