We have a 2007 TD4 an I am a big believer in fully synthetic oils having used them in two previous vehicles (Volvo and Merc petrol) and had as-new engine performance well into very old age.

However the LR dealer tells me that they only put semi-synthetic Castrol in this model because "fully-synthetic would damage the seals."

I asked a mechanic I know and he said that they would put fully synthetic in the 2010 - 2014 model because it has a DPF but that they should also put fully-synthetic in the earlier models, especially if a customer wants it, because it is a myth that current fully synthetic oils damage seals.

Can anyone help with a technical explanation as to why we can - or can not - use fully synthetic in a 2006 - 2010 FL2 engine ?

Thanks for reading.

Not an actual technical explanation, but: The correct oil spec for 2006-2010 TD4 cars is that which meets Ford WSS-M2C913-B. You can get this using Castrol Magnatec 5W-30 A5 (this superceeds A1) which is "fully synthetic". Oh, and "Ford recommends Castrol". 10MY (Sept 09) TD4 HSE Auto in Stornoway Grey (Now Gone)

email Castrol, they replied to me OK FL2 MY10 TD4 GS traded in at 2 years

Why would they lie about a thing like that? You'd think they would want to use fully synthetic so they can charge you even more!

not so sure that it's "fully synth"

Amusingly, although Castrol's own website recommends this oil (for the SD4, I didn't check every variant) , they haven't yet put up a link to the specification. Click through and it gives you the spec for their previous (A3) oil, which is part-synthetic. They DO have a page on the A5 elsewhere on their site, but it doesn't say whether it is fully or part synthetic.
Halfords website (reliable?) says the A5 is fully synthetic.
Edit - OPIE Oils, rather more reliable, also say it is fully synthetic. Ex AA Series III LWB Safari - Gone

Magnatec good enough but according to two LR garages I have used Castrol Edge fully Synthetic is what they use and say LR recommend.

I am certain that I have also read - probably here - that Freelanders for some years have rolled off the assembly lines filled with Castrol Edge Professional.

I am pretty sure that your dealer is wrong.

My dealer (TVLR) also use Castrol Edge, and I know others do too. Oddly, The Castrol web site does not recommend it for Land Rovers. Oh, and it's fully synthetic. http://www.castrol.com/en_gb/united-kingdo...range.html Ex AA Series III LWB Safari - Gone

here the spec, the Magnatec is now called "Start&Stop"

It's interesting to note that from the UK and Italian Castol Website we can read that the Magnatec " Uses full synthetic technology"...BUT in the German Castol website there's NO mentions to "full synth"

" Uses full synthetic technology" what means? Why they don't write simply "100% Synth"? Also the Hydrocraking is a "synthetic technology".

I don't know how it works in the UK market but I know that in Italy you can sell as "full synth" also the Hydrocracked-based oils....but this "stategy" is NOT POSSIBLE in Germany.

SO,.... """if 2+2 is not =22 but =4,""" I've some doubt that the Magnatec is really 100% Synth, and the label I've posted it's fairly clear

and oh, Hydrocracked-based does NOT MEANS that oil isn't GOOD oil



***in the German Castrol Website, it's also specified that the C2-C3-A3 version of the Magnatec are "HC-Synthesemotorenöl" ....in the UK and Italian Website the same oils are "fullsynth"... ****
