The diffs should have EP80/90 in them, and to be honest it’s not really worth mega high quality oils as they are basic old fashioned items. I go for more regular oil changes, than high very high spec oils. I assume your not running lockers or ATB’s which may alter oil type such as some ATB are mineral oil only.
I believe Americans call it 90 weight. |

I use Swepco which is from the States. 201 or 202 depending whether you have an ATB. WARNING.

Thank you all, how about engine oil? ACEA A5/B5 is not easy to find and advertised for Euro gasoline cars.

That’s a really old standard and virtually any synth made today is compliant. I use Castol Edge Fully synth.

Hi,
Yes Castrol Edge here too, I have just ordered some 5w 40 for the first time as its getting older and in a mild tune. A couple of points I can add is to be sure it has the 505.01 specification. This is required for Pumpe Duse engines 'PD' such ad the TD5 is. Also make sure it is diesel engine compatible, it needs the extra additives to cope with all the extra soot which diesel engines get in the oil. We had a customer recently buying what they thought was diesel oil in the USA but did not have the additives required for diesel engines.  |

For towing and Hauling, 80w90.
Otherwise, 75w90 will work fine. When the td5 came out it had an A1/B1 spec and this can mostly be found in 5w30 oils. A5/B5 is now successor of that spec but I am not a fan as it is a very fuel-efficient spec. Almost all 5w30 specs have the ACEA A5/B5 spec. I use, 5w40 with a A3/B4 Spec as this is a stronger oil and less likely to break down when working hard, or simply in stop and go traffic. |

in Canada I'm running my Td5 on Rotella T6 5w40.
Meets all the heady duty diesel oil specs. Td5 was specced with a wide range of viscosities and A1/B1 is now an old spec and almost anything modern will outperform it. Diffs get 80w90 GL-5 readily available. Although I just managed to get my hands on some Swepco 201. 2003 Defender 90 Td5 CSW Belize Green - "Betty" 1958 Series IIA 109 Station Wagon - "Randolph" - Awaiting Restoration 2019 Jeep Wrangler JL Rubicon - SOLD 2006 Volvo V70 D5 - Ocean Race Edition, SOLD 2003 VW Passat Estate 1.9TDI - SOLD 2008 BMW 320D M Sport Estate - SOLD 2001 Defender 90 Td5 Hard Top - SOLD |
