Can it hurt anything running used clean (no dirt) motor oil in your fuel. What is the most you all would put in one tank or what ratio would be good. i have run used oil before and it ran really well just makin sure it can't hurt anything.

 

Search the forums. There's tons of info. and opinions on that topic, but no it wont hurt.

 

Naw it wont hurt ,Im putting about 1qt of 2 stroke oil in per full tank of fuel

 

i have been running about a 20% (5 gal. per 32 gallon tank) mix of used oil in my fuel with no problems... i see a little more haze when cold an idling but other than that i cant tell a difference between the mix a straight diesel

 

is this to boost lubricity? or just to burn the used oil instead of $4.XX diesel

 

i do it for the price of fuel, i dont know if helps lube at all but, it burns

 

In my p7100 I have run some pretty serious percentages and get great mileage and power.The smoke does increase with large dosing.But I can control it with the skinny pedal.

I just dumped +- 10 gal into mine to top it off and i already had about 6 gallons in it so im at about 50-50 ratio and it runs EXCELLENT, now you think bout it and it is like diesel costs $2 per gallon so now it is cheap to drive

 

can this be done in the 03 common rail?

 

doubt it the commom rails pumps r diffrent, i run about 50 50 oil and diesel its cool!

 

this mornin my mtruck had a hard start, im running about 6 gallons oil and 5 fuel, but after idilin for a sec it went back to norm?

 

bet it smokes blue for a while untill it warms up.
