Thread: Td5 Disco 2 oil 15w40?

i would go with 5w

Too bad, that's not even a listed option for the Td5

+1 for the 5W... even better if it's dedicated for PD/EUI engines

+2 for the 5W

Penrite 5/40 hpr for larrabee 😉

An xW-40 is fine, and I'd go for an SAE40 over an SAE30 in Australia, particularly in summer.

Whatever Ricks use will be ok, most all people don't understand the SAE viscosity ranges.
In Australia, particularly in summer at higher latitudes there will be no difference in pumping pressures at start up between a 0W and 15W-40.

I use full synthetic 10w-40 as the land rover book is European specifications and in Australia and our warmer climate some oils recommend are not really suitable hear my line of though may be wrong but to date has served me well.

At operating temps there is no difference in viscosity between a 0, 5, 10 and 15W-40.

It's only at sub zero temps we see an appreciable difference in pumping pressures at start up.

Thanks guys, Im in brissy, usually hotter temps so it makes sense. Good to know there is such an active disco community!
