    M1 is a very good oil. Just follow manufacturers recommendation. More important is the oil filter. I use only Purolator or Wix, never any other brand, and change it at 3k miles. Using a syn oil: you can go longer than when using dino-oil, but the filter still changes at 3k.

    I don't use mobil 1, but I was told by a frequent user that mobil 1 filters are spec'd to last as long as the synthetic mobil 1 oil interval. Might be something to look into for less hassle.

    I believe most regular oil filters are good for up to 7500 miles now...

    This has been beaten to death so many times. There is no "best" oil. One is as good as the next. No oil will cause an early failure. "Best" is in your mind and the manufacturers marketing. They know that people are passionate about their cars and spend a lot of money trying to convince us that their oil is the "best" for our babies. Use the cheapest oil you can find or the most expensive and your engine life will be the same. Your engine does not need synthetic. If you feel better about using it, then by all means do so. ALL oils today are semi synthetic.

    Ok Ranger Im gonna put in Rotella 15W40 ive heard it's really good oil and works well and is good for the 4.9 and the distributor gear because it's thicker and has more anti-wear additives i have this at work i work at sears and it's only 3.99 a quart not that expensive so im going to use that instead.

    It's perfectly fine. It was recommended by our old Guru, a GM powertrain engineer. Can't get a better recommendation than that.

    ok thanks ranger sorry for being a pain i just read something on another website and it said about being to thick of an oil with pressure i can make the oil filter burst off and all this crap but if a powertain engineer said it's great then i believe it like you said can't get any better then that.
