The box said it's good for 10000 miles. I'm still gonna switch it out next time I change the oil though. I'll give the napa gold a shot then. I just don't know enough about them to notice a difference I guess

 

ive used fram for a good 10 years without problems

 

This is what my friend who has owned and operated a tire and oil shop for 35 years. Ya ya I'm old but I have also used fram till he told me to use napa its the most bang for the buck. He also cut a napa gold and fram in half for customer to see. Big difference napa has much more filter in it

 

Awesome! I'll definitely go napa next time

By the way... I love your jeep man!

 

Thanks you have a sweety your self

 

The old semi trucks like 80s had a mirror just so you could look at the stack and watch it so it does not start to melt away when your pullin a hill that English enough for ya I don't know why your pickin on me I just tried to help by Savin you some money and to not believe sales people

 

Wasn't picking on you my friend. Your punctuation and grammer left a bit to be desired. I honestly didn't understand what you were saying. Yes, that was much better thanks.

I am blessed with decent common sense and I'm not gonna be ripped off by many people. I was correct in saying the right oil frees up HP but I was incorrect in how much it was. I stand corrected. But 8-10 HP is fairly substantial don't ya think? I'd pay $15 extra for 10 ponies every 6,000 miles. The test I watched there was a 10 HP difference between Mobil one synthetic and royal purple.

I know for a fact 6.0 psd will run 20-30 HP higher with a 0w oil over 15w conventional rotella oil. I know that's in a diesel and not applicable in this situation but oil can be and is very key in many engines an running a good one will pay for itself in the long run.

 

I agree with you OOdynamite!!

I'm about to change my oil, oil filter and air filter. My '98 XJ 4.0 has 168,000 miles on it. I'm thinking of using Mobil 1 Full Synthetic, was going to use Fram filters but I think I'll give the Napa filters a shot.

 

Seriously guys look into amsoil. If you go with the 0w30 that's gaurenteed 15000 under the most severe conditions as in your xj has a 4000 pound trailer behind it 90% of the time and your driving through rush hour in chicago and 25000 for moderate condtions , occasianal towingsome trail use and for 35000 for fleet use. Or one year which ever comes first. This is with an amsoil filter too. There are so many reasons I recomend this to everyone here I can't put it all on. There are very few companies who will even test there oil against it because its that good. And there label sais #1 in synthetics and first in synthetics. They can't just put that on there either they had to apply for a patent and it was sent out to every single major oil producer in the world and no one could dispute it. I was skeptical at first and I spent 6 months researching it for my dodge ram 2 years ago and I became a believer.

 

People and there 6000 miles

 

No ****....4,000 here with Mobil 1 Syn.

 

The NAPA filter is made by WIX. I try to change my oil at 6000miles, but it goes to about 10,000 sometimes before I get a chance to do it.

 

Just curious how much that oil change costs you

 

so im doing my oil this weekend.

im thinking one of these oils:

and this filter:

I dont really mind spending an extra 5 bucks on a filter if it really will work better.


also, this is my first oil change (in general and on the jeep)
is there any additive i should add to get rid of any sludge/other buildups that previous owners may have caused?

 

That filter looks like it's good for extended drain intervals but none of those oils are. Some people might say Mobil is, but Mobil is not even a full synthetic.
