90 power ram

ok so i have been parking at them same spot at work for 4 months ad there is a oil mark the size of a 33 in tire were my truck sits same with at home but i check the oil every morning before i start it and it is always in the middle of the "safe" zone and never moves were is it all going? and my block is drenched wet with oil and fuel but i don't see any leaks. my mpg had almost been cut in half. is there some thing that i am missing i have a new fuel filter that i changed last time i filled it up.

Does the oil smell like diesel fuel? You might have a leaky lift pump, putting fuel into the crank case...Mark

It is thick like engine oil but it does smell like desiel fuel if was file would the pump be wet? Because it is dry. If it matters truck makes a clunck when you shut it off but it just started that how would I find if it is fuel leaking would my mpg go down is there any thing I would see or look for

pull you dipstick and smell the oil, if theres fuel in it you will know. and if thats the case you have two places to look: 1 fuel Pump

Make sure there aint coolent leaking into the fuel also.

My first thought when I read your initial posts...was like the others...fuel leaking into the crank case to replace the lost oil.

Get a clean white rag and lay it on the dripping patch. Then use your hand to press it down, then look at what it absorbs. Should be obvious if it's oil or fuel.
