My TD4 FL and 320BMW have the same engine (so i'm told)....

,,,BMW has to have Synthetic oil - the FL mineral - why so????

As you can probably tell i'm not a trained mechanic but i'm inquisitive!

The 1951cc engine is alright on semi synthetic oil.
Later 1995cc engines fitted in BMW's have particulate filters as part of emissions reduction. Fully synthetic oil to BMW long life spec is used to prolong the life of these filters.
 
just put 10W/40 or 15W/40 multigrade to spec ACEA A3 and ACEA B3 in it.

Castrol GTX diesel is good.
 
i sell the stuff all day long...it does..not sayin you cant put 10/40 or 15/40 in it but it should take 5/30. trust
 
its a 5w30 fully synthetic to BMW Longlife- 04 specn - at least that is the recomended oil.

yu use what you want :rolleyes:

just dont mix it.
