quick question.. in may bought an 06 with a hemi has 53k miles and time for an oil change and was wondering if it'll hurt the engine to switch to synthetic oil if it has only seen regular oil. does that make sense? is synthetic oil needed/worth it; all stock except for a 3865 super chip.

Simple answer yes its fine to use no matter on how many miles you have on it. The vescosity is the same so it's not going to leak if that's what you have heard. It's the same thickness. Only difference is that synthetic lubes a hell a lot better

I would never run synthetic if your truck leaks. Synthetic oil is made of smaller molecules or whatever. Its ment to help the oil get to the top of the engine faster to limit the amout of metal on metal contact. but if the truck does not leak oil it doesnt matter if you switch between the two. just make sure you run 5W20.

Castrol GTX conventional 10W-30 with Fram ToughGuard filter.
I have a couple of questions, though:
1. I see that a lot of people don't seem to like Fram filters. I realize that all of this is personal preference, but is there a legitimate reason to avoid Fram? I always thought they were a pretty reputable brand.
2. I have a lot of sludge, and thought that doing a couple of changes at around 1K miles in addition to a cleaner such as MMO or Seafoam would help flush the junk out (which is why I decided to go with the cheaper conventional oil and save some $$$ until I can get it somewhat clean and then maybe switch to synthetic). Would this help speed up the process?
3. This one is more rhetorical than anything else... Unless I'm severely misinformed, how on earth is it that a 5.9L engine only takes 5qts???
