D40 oil

SimonD40 · Mar 12, 2011

HI,

I own a 09 D40 auto th book said to use 5W-30, BUT, can i run 15W-40 low ash oil??

Also is anyone running a Chipit DPF delete pipe on a standard D40 with no chip, if so any issues ishould know about before i get one?

Regards Simon

Go for it.

15W40 is acceptable for diesel engines from about -15C upwards. 10W40 is suitable for use in -20C and upwards, 5W30 is used for more than 30 degrees C below freezing.

In Australia, you just aren't going to find a place that cold unless you work really, really hard at it.

If your not worried about warranty and or DPF you can use any oil you like...

Just don't use Oil of Ulan that's Dave's preference.

As far as I'm aware (according to the Nissan User Manual) you can ONLY use a 5w-30 oil if your vehicle is fitted with a DPF. The use of other grades of oil based on ambient temp is only for the manual trans vehicles.

In saying that, Nissan recently issued advice from their engineers that the use of 15w-40 was no longer allowed in these turbo diesel motors as they believe it is causing adverse wear on timming chain and their tensioners as well as excessive wear on the top end components. Whether they are right, or whether you agree with them, if you care about your warranty I'd be sticking with the recommended 10w-40 grade as a maximum for the manual trans vehicles and the full synthetic 5w-30 for vehicles fitted with a DPF.

Where was this advice issued, I wouldn't mind reading it for myself.

Howdy, I was told by the Motors service people here that you must use a fully synthetic oil with 5w-30w specs as any other oil tends to block up the DPF filter. As i used to use plain diesel oil and when i started with the synthetic i did notice better fuel figures.

The advice was given to me by the Customer Service people. I spoke with a couple of guys there and both had the info in front of them however I never asked them to forward it to me in an email. They were very stern with the warning and kept saying to me that it was only just released.

KraftyPg · Mar 13, 2011

I just realised it doesn't effect me because I don't use that stuff anyway so they can give out all the warnings they like.

Does this apply to all YD25 Engines? D22 and D40?

Ok well whats a good 5W-30. Penrite semi syn?

Krankin · Mar 15, 2011

give it a go....

I use 'Shell Helix Ultra' series syn oils.

roscoe07 · Mar 15, 2011

Yeah i did give the penrite a go but then changed the the 15-50. My mileage has gone down the gurgler and i wondered if the oil had caused it. Like 14l/100kms around town but thats for another thread.
