I have a 96 disco with 115,000 on it. Would 20-50 oil work well and what is the capacity?

 

The capacity is 7 quarts. I don't think 20-50 is recommended by LR. Spike will recommend 15-40 but I personally have switched to Royal Purple 5-40 because of where the truck is located. 15-40 would be too thick for me when it gets cold.

 

Depending on where you live and how cold it will get before your next oil change...20W-50 will work just fine. That is what I used to use in full synthetic form but I cannot get it anymore so I switched to 15W-50.
The "W" stands for winter use. So if it has a "W" in the nubers then it is ok to use in the winter.
Where do youi live?

 

Well if you live in some place where it is warm all the time, like...San Diego then 20W-50 is a good choice and you can use it year round.

 

Yep, good ole San Diego. I use 20w-50 in all my bimmers and it quiets them nicely as well. Thanks guys!

 

Agreed, I use 15W-50 and my LR and my wifes Volvo are both quieter than it I used a 10W-XX, like I said the only reason I stopped using the 20W-50 is because I cannot find it anymore in a full synthetic.
I ran it in my '01 Montero from the first oil change at 5,000 miles until I had to get rid of it at 100,000 miles, changed it every 5,000 and never once did I have to add oil or ever have a oil PSI issue, even in the dead of winter and it was below zero.
That engine was as clean after 100k as the day I brought it home with 62 miles on the OD.
I used Castrol Syntec.
If your tight BMW can take it then your loose Rover can too.

 

I run 10w40 Maxlife. Colorado is a touch colder in the winter so I run a 50/50 mix of 10w40 and 5w30. Don't ask me why because I really don't know.

Happy Roving,
