it has 168,000 on it. And a brand new timing chain

 

every once in a blue moon when i shift nto reverse or when i slow down rapidly as im pulling into my driveway my oil light comes on nd truks rpms die down a bit. almost like a hickup in the sending unit but i religiously change the oil every 3k with valvoline 5w30 HM and mopar filter and some marvel every change. just curious to see what the problem is here. hasent acted up enough to make me worried and look more into it. I also have abour two doxen baseball sized oil spots in the snow but oil level is still above the max line just slightly now for a month. there is an oil mystery with these trucks lol. not to steal the post from the OP i just digressed

 

On mine its fine but when I push the accelerator in 1st and 2nd gear it jumps and feels like it going to die. not sure whats wrong but it sure feels wierd!
