What's your oil?

Stroked777 · Apr 23, 2013

I hear different people running different oil, and after getting some work done to my truck I'm ready to change to a different brand of oil after seeing all the sludge under my valve cover. What you all running for oil?? Weight, brand conventional or synthetic.

Valvoline xtreme blue 5w40 full synthetic is what I run . im about to do an analysis in 1500 miles so we will see how it's making out.

lucas additive will make it start hard and sounds like a lope tune until the oil gets up to operating temperature.
i had an issue with a customer that kept adding lucas to a 2000 7.3 when it was new and he kept bringing it in for warranty, saying that lucas could not cause the problem.
ended up solving the problem by having his wife bring it in for a "free" oil change without his knowledge. a week later i called him and asked how it was running and he said it somehow fixed itself! :thumbup: then i told him that i changed his oil to solve the problem

That could have something to do with the 7.3 heui system. I donthing oil should effect a 6.4 idle

Yeah lucas oil additive is thicker than gear oil, I imagine that stuff will effect oil flow in an heui system.

Sorry to bump and old thread but what's everyone think of mobile synthetic 5w40? Or the ams oil synthetic 5w40? amsoil worth the extra money?

Tree Trimmer · Jan 26, 2014

if your set on synthetic, schaeffers is what i'd do.

conventional, pick your poison.

in a heui, oil is more........critical with what you run, shear is a major factor, and simply the amount of abuse the oil goes through. HPOP(or two), 8 oil abusing injectors, etc etc. schaeffers holds up towards the front of the pack, with a select few others.

on your 6.4, there is not near the abuse that the oil will go through, imo, so really, anything is fine.

I run rotella 15-40 in all my trucks have never had a issue. My 95 is bumping 300k so I'm sticking with it. I have ran lucas in them from time to time, my brother puts 1/2 gallon lucas in his 6.4 every oil change without issue.

Idk why it double posted.
