Proper reading of oil level on 2005 5.7L Hemi?
Decided to check the dipstick oil level of the 5.7L Hemi due to a "required" 3K Message change on my EVIC. Too my surprise, the level was well below the safe zone. Motor has 80K miles without any known problems. Added a dino quart of 5-20 and level is now between add and "full" on the dipstick. Primary question is as follows? Where exactly is the "full" indication on the dipstick and what intervals are most using for oil changes? I have researched on this site and answers range between 3K-5K. What is the comfortability index if changing at 5K? Talking Dino oil and not synthetic-I am not convinced that synthetic is required due to my conversation with a service manager who has sent out both dino and synthetic oils with "wear" results being the same/similar. Thanks for any help and suggestion(s).

Mine is always below when I'm nearing an oil change. Our engines do tend to use some oil and burn it up. It's all normal. Don't worry!

I do my oil changes every 3,000 miles.

The HEMI in general seems to want a quart between oil changes.

I've got two Hemi vehicles, one with ~50K (LX) and the other with ~69K (WK) and neither uses any oil between 6000 mile interval changes using synthetic oil. The WK used to use about a half quart between changes, but when I changed the cam and valvetrain I installed new valve seals and it now doesn't use any. I've had the LX since new, always driven it like I stole it and used synthetic in it from 6K on. Bought the WK with 48K on it and immediately switched to synthetic and started driving it like I stole it too. Also, IMO, the MDS seems to work better with synthetic.

Geezer, I think your change intervals and type of oil you use should totally be done with what and when you're comfortable with. Everyone has their own preferences and ideas, so weigh the pros and cons of everyones' input and then do your own thing. By the way, my LX takes 7 qts. and the WK takes 7.5 qts. to put it right on full. Why the difference.....I don't know, unless the pans are a little different. Also, make sure your PCV Valve is good. A bad, or even a semi good valve, will suck a fair amount into the intake. Have you checked the backside of the throttle body butterfly?

No sooner than 3K and no later than 5K with dino oil. I put 200K on a 4.0L Ford Ranger motor and finally the valve seats failed, runs but will not pass smog, on dino oil. It's hard for me to justify the cost of the synthetic but others here love it.

jeepg - Pans are a tad different(as well as the dipsticks, which was the part I was researching to begin with)

geezer - Lol I'm actually suprised you didn't complain about the pita dipstick they use for the Hemis. On that note 95% of Jeep owners and Dealerships will tell you between 3-5K is the golden zone depending on your driving conditions. If you would like to stretch it, tow frequently, or do 90+% stop-and-go driving I would be on synthetic. Otherwise dino oil is fine, granted I'd highly suggest a QUALITY dino oil. Most independents use a crappy store branded oil, the dealership uses Penzoil, which I would hands down recommend among dinos. I've seen the actual SAE tests and the Penzoil did a tremendous job at removing and keep sludge out of the system as well as held up the longest based on TBNs. But, alas, as long as its one of the big national brands you should be fine.

Since the next question is going to be filter type, if you aren't using the mopar filter then please take a moment and view the website below. As you will see there are several brands you want to stay far away from. Me personally I stick with fillters that have 50+ pleats (Mopar, Pure One, Mobil 1). I can generally get the Mopar 090 the cheapest and for some reason using the mopar stuff makes me warm and fuzzy inside(that could just be the mental instability coming out too lol!)

Doesn't the Mopar brand filters switch manufactures quite frequently? Hard to say who makes them at any given time. So I've heard anyways.

nah same mfg for a few years now.. there are only 3-5 mfgs that make filters in the US.

I just purchased a 2005 5.7L. The dipstick has a ton of twists in it. Is this normal? I did an oil change and put in 7 quarts but it still came a tad short on the dipstick.

Re: Proper reading of oil level on 2005 5.7L Hemi?
That's the standard dipstick. The twists are normal. You could add half a quart to bring it up if you like.

Funny thing is if you ever order a new one it comes straight, but has a note saying that it needs to be twisted to work. Lol gotta lol jeep engineers sense of humor.
