There are actually very few corporations that make motor oils, walmart oil is just a rebadged name brand oil. You should be fine, although all oils are not created equal, its not like a 4.0 is a high winding tight sport engine thats going to get bounced off its redline all the time an make long speed pulls...

Napa oil is rebadged Valvoline...

I dont know who makes walmarts oils, but I know walmart sells Mobil1 Full synthetic cheaper than anyone.

That my friend is entirely a personal preference decision you need to make.

High mileage is like..formulated to help engines with over 75,000 miles on them, the base oil is the same, but the additive package is a little different.

Synthetic is really slick, works great in most applications, helps dissolve years of sludge in an engine, this can sometimes, on neglected engines, cause oil leaks as the sludge dissolves and oil is allowed to seep...but this is more or less a rarity, but it does happen sometimes.

Conventional, well...the engine has lasted 181K miles on it without a problem..right? Its cheaper to buy, and the engine is familiar with it.

Viscosity, depends on the climate you are in..if you are in a cold climate, a thinner oil is suggested to ease cold starting and to allow faster pump up times. A thicker oil is preferred in hot climates, and on worn engines...

The oil debate is a discussion that rages on in all forums, small engine, automobile, off road, racing, 2 stroke..wankle engine, turbo charged, whatever...people have an opinion on what oil to use and why to use it. Sadly, few people ever agree, and there is mostly hear-say and and opinions running rampant.

In my mustangs, Ford says to use 5W20, I personally use a 5W20 Synthetic to help protect the engine at 6000rpms+.

In my 5.2 ZJ, I use conventional 10W40, it has 226,000 miles on it...I prefer napa brand (valvoline) as its cheaper than valvoline in the valvoline bottle..

I change my oils between 3000 and 5000 miles, and I use Napa GOLD filters (wix premium).

I agree with above. I personally recommend Rotella T6 full synthetic. 5w40. They have it at Walmart in Gallon and quart sizes. A tapping noise I thought was normal completely disappeared after the oil change If you want to spend the little extra money try the HDEO, many people swear by it, and it is packed with additives and detergents since it is for diesel engines. Hopefully that means my jeep's insides will be squeaky clean lol

No matter what oil you use though, I would insist upon Pureolator pureONE filter. Its the best money can buy and the filter is probably the most important part of the oil system.

You can do the I-6 engine an additional favor by using a larger filter. Adds about an extra half quart of oil capacity and more than doubles your filtering area, which helps with pressure drop across the paper and filtering capacity.

Motorcraft FL-1A
Purolator P30001
Fram PH-8A

It's a Ford small/big block filter with 3/4 x 16 thread and same seal width/diameter; these listed are all equivalent, there are more equivalents but these come to mind.

I live around Philadelphia, so the winters can get 20 degrees F. And I was wondering if thr rotella T6 would be too thick for 20 degree weather?

T6 is 5w-30 or 40 right? Although I have read that it's thicker than normal oil it should be fine. If I lived where it got below 0 I would use a 5w oil. When you get to the 20w is when I would worry that it could be to thick for the pump on start up. But everyone has a different opinion.

If at first you don't succeed, use more speed.

I can't believe I never knew an FL-1A was a direct fit.
