[Engine] Hdi oil grade

[Michael_mill]

Evening all, I have a 2.0 hdi. Oil change its getting close, just wondering what's people thoughts would be on using john Deere plus 50 oil it's 15w 40?  

Thanks Michael

Go to a site such as Opie oils http://www.opieoils.co.uk/ and look up your engine to find the correct specification and recommendations.

15w-40 is a bit thick when cold and is not one of the grades recommended for the 2.0 HDI, so even if you can get it for free it's a bit of a risk especially in the winter months up north.


10w-40 is listed as being a grade suitable for the 2.0 HDI but personally I would rather use 5w-40.

You don't need to buy top notch expensive oil if changing it frequently (6-7k) a 5w-40 semi synthetic will be fine....well it has been in all of my turbo diesel vehicles.

I just recently put 5/40 Fully Synthetic in mine. I hope I've done the right thing as that link that Solent provided ^^^ seems to point to 10/40 Semi Synth.

btw Michael, have you read the stuff about the importance of draining the old stuff correctly? (though more important on the 1.6, apparently)

You can use 10w40 semi but 5w40 fully is better - we wont go into whether fully synthetic is really fully synthetic.  

That site seems to advise on the lowest spec for an engine it suggests my 1.6hdi is 5w40 when that spec was changed by Citroen years ago to 5w30 low SAPS.

Was the spec not changed by Citroen when the engine was fitted with a Diesel Particulate Filter (DPF) so 5w-40 would be fine if you had a 1.6 hdi with no DPF.

The JD 15w40 will be a bit too er dare I say agricultural :-) It may well not protect your engine on cold starts and will be harder to start. Also it may be Dino Multigrade oil, if so best for the mower when compared to modern oils.

From what I read in the Citroen documents, you can use 10w40 semi synth as a minimum or 0/5w40 fully synth. I put 5w40 in my 2.0HDi and will probably do the same again in a few months after winter.

I have no shares in ECP or CP4l, but thought that I'd mention they have 50% off on oils this weekend a very good deal for 10w40 Semi, or CP4L may be slightly better for 5w40.

Not quite JJ Citroen changed it across the whole 1.6hdi range - more to do with oil drain intervals and turbos, my mate who works at Citroen told me. I know because i asked the question about 5w40 because i was using it, his reply was dont. There is also the idea that the low saps helps to keep the EGR valve clean, but this may just be tall tales?
