good oil to use. I use Royal Purple, but many use Mobile 1 or Castrol Synthetic. The important thing is to not extend your drains. The engines run too rich. Don't go past 5000 miles.

 

castrol 5w30 every 3000 miles. I've donecastrol w/ every car I've ever had and swear by it.

 

i guess the more general question i was wanting to know is the weight. i was using 0-40 in the bmw, now i know that isnt for the LR but i am reading 5/40, 10/40 etc. again chicago area and getting cold!

 

I like a good synthetic 10w40.This weight has been working well in my Discovery.

 

I run 10W30 in the winter

 

I run the 5W/30 Syntec in the winter, 5W/40 in the summer and yes your truck will like the Mobil 1 also, remember use a good filter like a K&N 3001 or a Mobil 1 so you don't have any dry starts.

 

i use 5w-40 all year. either rotella synthetic from walmart or amsoil online. engine cranks when temps are below zero and still runs smooth and quiet in the summer.

 

I have been using castrol 5w30. I have the service done just before5000 miles.
I have been suppling my garage the filters (K&N). I have been ordering them online. Not all the filters can be obtained from the local auto parts stores.
My truck is in New Jersey which only gets real cold weather in late January thru end of February.
