5-40 10-40 oil

[Roy]

what is the difference???

 

[Mike Roberts]

The difference is 5... LOL!

I think the low number has something to do with its cold start protection. 10-40 for example would be used in hot climate??

The lower the number the better cold start protection.. 99% sure

It's a viscosity rating. The lower the number the less thick (viscous) it is. Is it's thinner, when it is cold it will get around the engine parts more easily.

Use only 5w-40 on the F4R engine!

Use only 5w-40 on the F4R engine!

Why? ..

Why? ..

Well, apart from it being clearly stated in the manual, Dialogys pdfs etc., take it from a former Megane II owner - the lifetime of the dephaser pulley on Renault VVT engines needs lubrication and it needs it fast

Obviously, 0w-40 would be good too, but oil consumption would be higher I think...

Thanks. (ευχαριστώ)

Mobil 1 0W40 is great oil, might be worth a go to see what the oil consumption is like..
