Shell Helix Ultra

Any reason not to use THIS oil in my diesel Colorado?

Nope - but you do know what sound an opening can of worms makes?

Another choice would be http://www.opieoils.co.uk/p-997-fuchs-t ... iesel.aspx

which has a considerably higher spec for diesel engines

I would not advise spending too much on oil for a simple engine unless you want to significantly increase the service interval. I used Jim's suggestion and did well over 10k miles, got the oil tested and it came back fine, virtually unused apart from a bit of sand deposits. However I did a lot of long drives.

Basically just use the cheap stuff: http://www.opieoils.co.uk/p-990-fuchs-t ... e-oil.aspx (not that this is a poor quality oil)

I decided to give the Shell oil a go. I haven't tried fully synth in my truck yet, so a drum of the stuff should be enough to be able to tell whether it makes any difference over semi-synth. I have seen that when I used Toyota oil it burned a bit of oil between changes (this was last winter). The Castrol Magnatec didn't seem to need an top ups between changes, until the weather started getting colder..? The Shell is 5W-40 rather than 10W-40 so should help a bit with cold starting (if my understanding of viscosity ratings is correct...).
