Halfords 5W/40 Synthetic Diesel Oil (and it comes ib 5lt

I think the manual specifies 5W/30 ?

the main dealer gave me 10/30…

a little thicker when hot cant be a bad thing can it?

Hot??? where abouts are you?

I just looked in my manual, says 5W/30, as you say if it’s hot then the thicker stuff may be better?

The thing that would worry me is the fact that a lot of damage gets done when an engine is cold, like when first starting etc, that’s the time a thinner oil will benefit, finding it’s way through all the journals etc.

personaly i’d stick with the 5W/30

5w/40
5w for cold starts and 40 when the engine is hot
