Anyone recomend the best oil to go for for a 2.0 tdi 140? Recomended is 5w 30, but some say 5w 40. What do you guys use and which brand etc?

- Thread starter Leon MK4
- Start date
Do you know any stockists of Quantum oil? Tried Halfords and ECP but they dont seem to stock it. I know TPS do it but don't you need to be in the trade to buy form them? Wanted to just go and grab some rather then have to wait for an online delivery

I got mine from VW dealer but I know a guy in parts so got discount on oil and all the filters for Leon. I think GSF do Quantum oil.
Was in Asda last night and they do Castrol Edge 5w 30 and 5w 40, 4 litres is £32 I remember rigtht. Got a 1 litre bottle of 5w30 to top mine up until the oil change is due. Figured this oil has to be one of the best surely....?
Whats the diff between the 5w30 and 5w40? - I know both can be used on these motors....

From Wikipedia:
Multi-grade
The temperature range the oil is exposed to in most vehicles can be wide, ranging from cold temperatures in the winter before the vehicle is started up, to hot operating temperatures when the vehicle is fully warmed up in hot summer weather. A specific oil will have high viscosity when cold and a lower viscosity at the engine's operating temperature. The difference in viscosities for most single-grade oil is too large between the extremes of temperature. To bring the difference in viscosities closer together, special polymer additives called viscosity index improvers, or VIIs are added to the oil. These additives are used to make the oil a multi-grade motor oil, though it is possible to have a multi-grade oil without the use of VIIs. The idea is to cause the multi-grade oil to have the viscosity of the base grade when cold and the viscosity of the second grade when hot. This enables one type of oil to be generally used all year. In fact, when multi-grades were initially developed, they were frequently described as all-season oil. The viscosity of a multi-grade oil still varies logarithmically with temperature, but the slope representing the change is lessened.[8] This slope representing the change with temperature depends on the nature and amount of the additives to the base oil.
The SAE designation for multi-grade oils includes two viscosity grades; for example, 10W-30 designates a common multi-grade oil. The two numbers used are individually defined by SAE J300 for single-grade oils. Therefore, an oil labeled as 10W-30 must pass the SAE J300 viscosity grade requirement for both 10W and 30, and all limitations placed on the viscosity grades (for example, a 10W-30 oil must fail the J300 requirements at 5W). Also, if an oil does not contain any VIIs, and can pass as a multi-grade, that oil can be labelled with either of the two SAE viscosity grades. For example, a very simple multi-grade oil that can be easily made with modern base oils without any VII is a 20W-20. This oil can be labeled as 20W-20, 20W, or 20. Note, if any VIIs are used however, then that oil cannot be labeled as a single grade.
The real-world ability of an oil to crank or pump when cold is potentially diminished soon after it is put into service. The motor oil grade and viscosity to be used in a given vehicle is specified by the manufacturer of the vehicle (although some modern European cars now have no viscosity requirement), but can vary from country to country when climatic or fuel efficiency constraints come into play.
