Disco OILS

Hi all

Just a quick one about OILS
I'm due to get a Disco 1 in Jan and want to replace all the oils. But which one should I go for.

I can get hold of OMD "Oil Mineral Detergent" 5W/30 and 10W/30 which one?

The 5W is Fully synth and the 10W Heavy duty semi Synth.

Hi heggars
Depends Petrol or Diesel & ambient temperature 10w 40 is listed for both types of engine in my owner manual although i'm using 5w 40 fully synth in my engine at present.

for a diesel 10 40 or 15 40 semi synthetic

As with the price of petrol I'll be going down the Diesel route me thinks.
Thanks for the info, from what I have read the first figure is how fluid it is cold and the second number is when at operating temp, so the last figure doesn't make to much difference?

So would you say that the 5W/30 and 10W/30 are to thin for Diesels then.

Search Castrols site for the right oil.

Here's the link http://www.castrol.com/castrol/iframe.do?categoryId=9024084&contentId=7044829

Hi Stu, I work on the principle of putting in high quality, fully synth oil in and changing it every 6000mls.

I use 5w-30 in the winter and 5w-40 in the summer. My rationale is that the 5w figure means it will be easier to turn over the cold engine in winter and it truly does help the car to start better 1st thing in the morning !!

I think that i may go for the 5W/30 then as it's fully synth and pretty much free.........lol

The second number means that the oil will not get any thinner than a 30 grade oil when its at operating temp.So 10w/30 will be thinner at operating temp than 10w/40 ya dig?

SAE stands for the Society of Automotive Engineers, based in the USA. The SAE grade specifies the most important parameter for engine oil mainly its viscosity. In other words it tells you the "thickness" of the oil. The lower the number, the "thinner " the oil; thus SAE 30 is less viscous than SAE 40.

That will be at all temperatures.
