Question Whats Your Oil? (4.7L HO)

I've been running pennzoil 10w-30 and it about that time for yet another oil change. Just wanted to see what oil brand everyone else is using for the 4.7L HO.

I was thinking about changing to CastrolGTX .

Thanks in advance everyone :-)

Mobil 1 10-30 with either a Mobil 1 or purolater filter and 8000 mile intervals. I actually change the filter at 4000 and top it off, then a full change at 8000.

There are quite a few oil threads on here.

http://www.jeepforum.com/forum/f310/...-4-7l-1327729/

Here's a couple discussing oil weight:

Mobil 1 HM or Rotella T5 are both good for either engine.

A search for 'oil' brings nothing up. Perhaps the word is to short (though there is not warning for that in the results). Quite amazing really considering how much that term is used.

Try this next time - in Google's search box:

site:http://www.jeepforum.com/forum/f310/ oil

Replace the word 'oil' for whatever it is you want to search for in the WJ section.

x2 on the WIX filter. They occasionally make it into my rotation as well, they are just a little hard to find around here for some reason. I can usually find at least one of the three (mobil 1, purolator, or WIX) at any of the parts stores around, so depending on which store I happen to be in, decides which filter I go with.

I use Mobil 1 HM 5w-30 in my 04 Overland. Changes every 4k miles. You should really be running 5w-30 in your 04 HO. The 02-03 models use 10w-30, but Chrysler revised the oil pump in 2004 and recommends 5w-30.

Just an FYI, MySQL has a default minimum word length for full text indexing/searches of 4 characters. So unless the server admin changes this to 3 characters, a 4 letter word is the smallest thing it can ever find. Unfortunately for car sites, this leaves out a TON of things.... ABS, PCV, IAC, TPS, PSI, etc. The car forum I ran was on my own dedicated server, so I was able to change the MySQL config file to allow 3 character indexing/searches.

Oh, and I run Valvoline Synthetic 5w30.

Using a Google site-specific search helps. "site:www.jeepforum.com WJ 4.7L Oil"

Ahh a MySQL'er... It's been over a year since I've used open source. Loved it though.

And on subject, I concur with billzcat1.

Valvoline MaxLife Full Synthetic 10W-30

I use Valvoline VV180 MaxLife Synthetic SAE 10W-30 and a K&N HP-2004 filter and change every 3000 miles.

I get both the oil and filter off Amazon with free 2-day prime shipping.

I switched to this oil at 88,000 miles, I had the dealership do my 90,000 mile service then and since then I've been doing all the maintenance myself to save money.

I haven't noticed any performance gains, which you should not expect from oil anyway, but I am confident that my engine is being protected better and also cleaned better because Valvoline synthetics use good detergents.

The K&N filter is extra strong and used in race vehicles, my favorite part is the 1 inch bolt on the bottom because getting a filter wrench around the filter in my 2004 Overland is a real pain.

Always hand-tighten your filter, never use a wrench to put it back on. Just wipe the oil off and put some muscle into it and it will be fine, and a lot easier to get off at the next change.

Great choice, but that is serious overkill, you should be able to get 5k out of that easily, save some money for something else your Jeep needs.
