Oil & Filter Change Discovery 3 - 2008 2.7L TDV6 EURO4 Engine non DPF 5w40 Castrol Magnatec C3 Oil

Best oil for Discovery 3 TDV6 engine? Time to test out if the LR-Time theory is correct, in a practical way, so 5w30 will be replaced with 5w40.

My car has been using Castrol oil for as long as I have owned the car, and for that time I have used 5w30, up until now. I have used Castrol Edge and Magnatec Start and Stop, both 5w30, for the past 10 years.

I went with Magnatec C3 Oil because it is within spec and was on sale. There are many option out there so check your engine specs or check with your mechanic. I'm not a mechanic and this is not a how to video.

They say that you should never change your oil type, but what's the fun in that. The car, with it's 2.7L V6 engine is running good and I have faith it in continue to do so if I change out the oil regularly, no matter if it's 30 or 40 oil.

And if all things fail, I now can blame Christian and Vera ‪@Vera_and_Christian‬ , so problem solved. 😂

There are many things to consider when choosing the right all, not only the consistency, thickness of the oil, but all of the additives is as important. So do your research and don't belive everything you see on the internett.

The quick summery of the 40vs30 oil is that LR changed from 40 to 30 oil because of the environmental aspects and fuel economy. You can see non euro countries still uses Edge 40 oil. The other aspect/theory being that it is better to run a thicker oil on a older and more warn engine, as the oil lingers longer in the crevices.

I'm no mechanical engineer so I wouldn't the deep science of this, but I get the basic ideas, and I can understand the importance of the correct additives in the oil. My point being, again, read up and make up your own mind.

My engine is at 250 000km and still running so I must be doing something right, the goal is 300 000km, but I'm thinking that everything above 200 000km is a bonus on any old car.
