Thread: D2a oil Question....

The handbook for a TD5 D2 gives 5W-30 full synthetic as the oil to use up to the maximum temperature on the page with an option of 5W-40 AFAIR.

I use Nulon diesel 5w-30 full synthetic and had zero use on my trip around the block, although it didn't really get over about 35-38C.

IMHO you can safely use 5W-40 and many use Penrite semi synthetic 5W-40 diesel but the TD5 was designed for light oils so I personally wouldn't go putting HPR30 or whatever in.

I'm no expert but full synthetic oils resist heat related breakdown I believe .
We use Penrite Full Synthetic 5w40. Have read of people up that way using 10w40 and even 15w40..but I'm not sure I would . If your cooling system both coolant and oil are up to scratch I couldnt see what difference the viscosity of the oil would make in high outside temp . A quality full synthetic should see you right .

this is on sale atm , Castrol EDGE 5W-40 SN | Features and Recommended Engines | Castrol EDGE Australia should be fine? , my other landy is a v8 and doesn't really care what oil it eats

I prefer a specific diesel oil personally.
Full Synthetic 5W-30 Diesel Formula Long Life Engine Oil- Nulon Australia

dexos2 Brands | GM
If you note that those particular Edge types are not Dexos 2 approved.

I don't know how important that is but all being equal I prefer the highest spec.
While Edge is on special now , will it be next time you want it?

I am looking at it for my Jazz but agian I use Nulon full Syn 5-30 petrol type oil for it, and wonder if its worth changing to save $20 .

hmm looks good i think ill be getting a full synth then , thanks

Yes, fully synth is the way to go, and if you want the best for your engine there are oils specially formulated for EUI engines, it's specified on them " for unit injector/PD engines" , my mechanics told me after they opened the Td5 that it's very similar with the VW PD engines and such oil is the best for it...maybe it's a 'placebo' but it seemed to me that the engine is smoother since i'm using this kind of oil(Comma DPD 5W40 fully synthetic) , the previous owner used some poor quality oil i think

This is from D2 RAVE:

Slunnie My RAVE says Petrol like you have but diesel 5W-30 ,5W-40, 5W-50 for all temps on page 175 of the owners handbook . Your graph appears to be for petrol only. Diesel is different.

The graph won't copy but you will see petrol is different to diesel.
Petrol is 5W-30 up to 35C and 5w-50 for all temps or 10W-,40,50,60
