Just curious, the K&N website only lists an HP-2004 Performance Gold filter for a 2003 Disco. When I do a search of the HP3001 model the main difference I see is that it is about an inch and a half longer. Is slightly higher volume the main reason some of you prefer it?

 

yep, and I use....

Yea, I'm switching over to that on my first oil change next week. I had real good results with that on my old Suburban (last car). What weight are you using and how often do you change the oil and the filter OKDISCOGUY?

 

Mopar oil filter, Mobil 1 15w50,change it every 5,000 miles and I have 170k on the clock.

 

I go 3K, but don't go over 5K miles. I am a distributor, so I get it at cost.....

I did an oil analysis, and there was a high amount of carbon and fuel at 9K. These engines just aren't lean enough to run extended drains.

 

Thanks, I'm going to go with 5w-30 until it warms up (I'm temporarily living in Atlanta, GA not Texas) and then move up in weight as the weather warms up.

 

You guys who live where it is "cold" crack me up. How cold does it get in GA? 60? maybe 50?The numbers on motor oil go like this...
5w30= it will pump easily through the engine at 5 degrees F and give the same protection as a 30 weight oil.
10w40= 10 degrees and protects like a 40 weight.
0w20= it will pump at o degrees and protect like a 20 weight oil.
The lower the bottom number the less resistance inside the crank case when cold and it helps engine manufactures meet EPA requirements. The Prius says to use 0w20, so does Ford, some Hondas and others. The less resistance inside the crankcase the better the MPG. BUT...the lower the numbers the thinner the oil and the more you burn oil.
Lets remember that oil thins out as it gets hot. So if your car uses oil than a thicker oil is what you need.
In cold climates you need a thinner oil so that it pumps faster at startup and reduces emissions by reducing resistance in the sump. The crankshaft is partaly submerged in oil inside the sump.
If it only gets down to 50 in your area or maybe down to 30 twice a year, you can use any oil you want 0w20 to 20w50.
But basiclly the FIRST numberis the actual weight, or thickness of the motor oil and the SECOND number is the amount of protection that it offers.

 

Thanks for the primer on viscosity, I feelbetter educated![sm=thanx.gif]Now I just need someone to explain the numbers when my doctor takes my blood pressure!

We've had many mornings in the 20's but as low as 12 degrees a couple of times. Definately not as cold as other parts of the country. Personally, I try to just stay in bed on mornings like that!

 

5w30 from April to October Synthetic of course.... Have always used Syn. in all of my vehicles.
10w40 remainder of months. Always K&N filter...Great filter!!!!

Change at approximately 4000 to 5000 miles. Have noticed in Rover motors need to change closer to 4000. Tolerances are not as tight as some other makes. Had a Toyota I could change every 8000 to 10,000 and oil was still pretty clean. Ran that truck over 360,000 before trading in.

Asking what type of oil to use is like asking, "what beer should I drink?" I agree with Mike, that a good filter is extremely important. I have been using Citgo oil in all my vehicles for 20+ years, not because I think it's the best, but because I can consistantly get cases really cheap. But it's good oil, just like others out there, meets specs. I've got4 vehicles over 200k miles right now that I've used it in since I've owned them. I always use AC Delco filters, or Motorcraft on our Jeep. I think Motorcraft (FL1A) is a very good filter that you can get a t a lot of places.

Synthetics are the best, and I use Mobil 1 in one of my vehicles. I say as long as you change regularly and use a good filter, any name brand oil will work fine. Just stick with the same brand between changes (don't mix).

I don't know about the K&N filters. If they were so great, every manufacturer would be using them. There is lots of talk about them messing up MAF sensors. I'd rather have premium filtration than a little better flow. Dust in the airstream will cause a lot more wear.
