I own a 2000 Durango (4.7) & 2002 Dakota (4.7). They both have Mobile1 5w30 and Napa Gold Filters. Even after I change the oil and replace the filter (with no oil in the filter) the initial startup has no abnormal lights comming on. I am not saying this is how all Dodge's will react, some may react like vsixer. But do not jump to conclusions about the oil causing this, seems like muffler bearings to me.
Minus the attack on preperation H, I do know that Amsoil is one of the best out there. I run it exclusively in my 98 S&S V-twin, (which is air-cooled). 100 degree days in California are killers on air-cooled performance.

I installed a mechanical oil pressure gauge in my 97 Dak after losing a 5.2 magnum engine with 80K on it. Recently I've noticed that the factory oil gauge is slow to respond during a start. Good news is that the mechanical gauge comes right up as soon as the engine starts. The factory gauges are not very accurate and the sending units do go bad, so you might want to install a mechanical gauge just for piece of mind.
One thing you'll find is that the mechanical gauges usually indicate lower than the factory gauge. My 97 Dak idles, when hot, at about 15 psi, while the factory gauge is indicating somewhere around 30 to 40 psi. The Haynes Manual lists the minimum oil pressure for this engine at 6 psi at curb idle. You'll never see that on a factory gauge.
Also, be aware that there is a problem with hardened oil debris accumulating in the oil pans, of 5.2 magnum engines and maybe others. This issue is well documented in these pages. Most think that the hardened debris flakes off of the bottom of the pistons and accumulates in the oil pan where it can eventually clog the oil intake screen, causing engine failure.
When I pulled my 5.2 after it spun 2 rod bearings, I didn’t know enough to check the oil pan for carbon debris. The oil screen and everything else in the oil pan was covered with extruded bearing material, so it may not have been obvious anyway. This engine came apart w/o warning, under normal load, at highway speed, with the correct amount of oil in the pan. To my knowledge it had never been abused, it was never used for towing and the oil was changed every 5 to 6 K.
Anyway, the moral of this long story is that what you don't know CAN hurt you. If there is a real problem with oil pressure a mechanical gauge will tell you things that the factory gauge won’t. It may even save an engine. Good Luck…

Since this thread has become a discussion about oil filters, I will post this. From what I can gather, here is what is out there:
Honeywell - makes Fram (In Canada the Quaker State filters are Fram filters / In the USA, QS is Purolator), Pennzoil, Quaker State
Arvin Meritor - makes Purolator Premium Plus, PureONE, Ford OEM, V-1 & SureFlow (Superflow?)
Dana - makes Wix and Napa Gold/Silver, AC Delco DuraGuards for Canada
Baldwin (Parent of Hastings) - Baldwin, Hastings, Amsoil, Casite, maybe others
Champion Labs - Mobil 1, K&N, Supertech, AC Delco DuraGuards (two different types) for USA, Bosch Premium, STP, Ultraguard Gold, Deutch & Luberfiner
Cummins Engine - owns Fleetguard
Mann - a top quality German filter maker (for our many German Friends on this site).
Castrol Filters - a difficult question to answer. From what I know Castrol Oil Filters are rebadged, and manufactured by various other companies. I have been told their "high end" filters are manufactured by WIX, and their "low end" (white filter) is manufactured by FRAM, and is the same filter as PENSKE which is also manufactured by FRAM.
Please add to (or correct) this list if you have any more information on filters or filter makers.
__________________________________________________
If you're set on getting a $5 filter, then Bosch Super Premium or Wix. Reasons: Top notch construction, good filtering, and good flow. (The PureOne is in this price range too, but I've got issues with restricted flow in the PureOne because of the densely packed media.)
Second - if a slightly higher price is okay - might I recommend Amsoil SDF Oil Filters, and yes a bit over $5 at the $7 level (Amsoil Preferred Customer Price and / or Dealer Price). Well constructed. Strong. Excellent by-pass mechanism.
Amsoil Super Duty Filter (SDF) Oil Filters
AMSOIL oil filters are made by Hastings, which is a subsidiary of Baldwin. Baldwin still manufactures and markets under both the Baldwin and the Hastings name (Hastings and AMSOIL are made in the same plant in Nebraska) . Baldwin representatives told me that the AMSOIL oil filters use a better grade of filter media, found in only a VERY FEW of the Baldwin filters - simply a matter of economics - it costs more - therefore the reason for the higher AMSOIL Filter price (not a middleman markup or re-badging).
Amsoil filters are not Hastings! The confusion is that Amsoil just markets the Hastings brand so their dealers will have a source for EVERY filter application imaginable. Amsoil offers and sells Hastings filters but WILL NOT sell Hastings filters for which there is an equivalent Amsoil filter.
Amsoil Super Duty Oil Filters (SDF) offer all-around better filtration and protection than conventional filters. Full flow design for extended drain intervals and severe service. Our filters contain a high-tech blended filtration media composed of cellulose, synthetic and glass fibers. The media sets the Super Duty apart from conventional filters in capacity, efficiency and service life, delivering superior filtration and protection.
The AMSOIL Super Duty Oil Filter (SDF) is designed to provide maximum filtration while meeting the high flow demands of modern automobiles. The AMSOIL SDF contains a special cellulose, synthetic and glass blend media that offers the best possible balance of long life, high capacity and overall efficiency.
The AMSOIL SDF has a lofted fiber depth-type media that traps dirt throughout its entire thickness for exceptional filtering efficiency. It keeps oil clean and free of wear-causing contaminants.
The AMSOIL SDF has a heavy-duty case of drawn steel. The case is double-crimped at the base with rolled-under seaming to withstand extreme pressure surges and road shocks.
The AMSOIL SDF has an anti-drainback valve that keeps trapped contaminants in the filter when the engine is not running.
In the case of Amsoil filters, I understand the media is different in that they use a synthetic type. The Amsoil filters are rated at 98% effective at 20 microns and about 65% at 10 microns. The information I got from Hastings is they are 98.7% effective at 45 microns and 50% at 22 microns. Baldwin also uses a type of synthetic in their filters that are rated "severe service". I don't have any numbers on these. Not all Baldwins are rated severe service. I think that their severe service filters are for heavy-duty equipment.
When AMSOIL went to Baldwin/Hastings with the specs for the "then new" Mobil 1 oil filter, Baldwin told them that they could certainly manufacture filters that could outperform it, simply by changing to the new media - which they did for Amsoil - which is why many feel the Amsoil Filter is superior.

Thanks for the filter info Steven.
