I own a 2004 Disco and have been reading the forum on best oil to use.

I live in Greenville, South Carolina and can't find Rotella T6 20w50. Can't find it online either. Any suggestions?

Thanks.

 

Honestly, I don't think rotella makes 20W50. I used to run 20W50 in my RX7 and Royal Purple was seemingly the only company that makes it and has it readily available.

I'd check Amazon, because they have seemingly everything. But seriously 15W40 should do the trick and if that isn't doing it for you a lot of people go to 5 or 10W40.

 

20w50 isn't that a little heavy? i think rotella only goes to 15w40

 

T6 is 5W-40 (Synthetic)

Mobil Delvac makes a 20w50. But Shell Rotella does not.

 

Thanks. When I purchased the Discovery the previous owner told me he used Rotella T6 20w50. I wrote him last night and he said he used Rotella T 20w50. Can't find that either.

Truck had a slight engine tick when I purchased it. I changed oil and didn't use Rotella and it is louder now. Would like to quiet it down and again, previous owner recommended returning to what he used.

Thanks for your advice.

 

He is mistaken. As far as I know and can tell Rotella T does not come in 20w50.

Call Shell yourself and find out!

Ralph is correct about rotella and oil weight.


I run RP 20-50 starting late spring and running to early fall. I then switch back to Rotella diesel, t-6.


Of the two oils, I think my '03 disco likes the 20-50. Just seems to sound a bit quitter. Oil junkies here on the forum swear by rotella and the zddp properties and how great it is for the engine. While I will not argue with them as I don't know much about oils, I do defer to these gurus. However, it just seems that my landy likes the RP over T-6. And just as a side bar, I thought I read somewhere on the RP website that they too also add zddp to the oil. However, maybe I misread something.

 

You'll be fine with the Rotella 15w40.

Wall Mart $12.98/gallon

There are dozens of manufacturers of 20w50 engine oil. I use Castrol GTX 20w50 in the 3.5 V8 in my Triumph, which is really getting on a bit.
