ive been hearing people with big injectors (200+hp) say they change their oil every 1500 miles b/c they are affraid there might be fuel in the oil and they dont want to wash down the cylinders...

how does fuel get in the oil and how do you prevent it??

does your oil have to be analyzed to determine if there is fuel in the oil??

lots of questions but im a little concerned running the big EDM's...
 
Idk about fuel in the oil from big sticks but I was getting alot of excess soot buildup in my oil from blowby on my old truck. It's a combination of having big sitcks, high boost/cylinder pressures, and in my case a 280,000 motor that had been worked hard. But like you said I'd just send out an oil anylasis just to determine what your oil change interval should be.
