5 W 30 fully synthetic oil in a D24
 

hi all i have raised this question before . i have purchased 10 litres of this oil good brand here millers . a mechanic has said to me do not put this oil in a D24 its what volvo recommend now , but my guy says the engine needs a 5W 40 oil
i don't want to give it away as i paid £50nhere can i safely use it and then go on to use 5 W 40 in future ?
regards jim

Who is your guy? What are his credentials? At lower ambient temperatures (I think that describes your environment?) I would run 5w-30 full synthetic current spec. diesel motor oil no worries.

5 w 30 fully synthetic oil
 

thank you for your valued comment NGOMA there was a past comment on here that 5 W 40 fully synthetic oil is the ideal oil but there as you say 5 W 30 in the uk climate is acceptable .so the general view here is i will be ok with 5W 30 in my 1995 D24 . and see how i feel i wonder how many different types off oil is used
by you guys in our D24s ?

Full synthetic here, have used various weights: 5w-30, 5w-40, 10w-40, 15w-40?

Here is a photo of what I currently have in the garage. As I am on a tight budget (trying to get a kid thru college) I tend to buy whatever full syn is on sale. Most recently that seems to be Rotella T6.

oil
 

thank you NGOMA i see your oil is 40 grade thats what my mechanic said i must use too , but volvo recommend 5w 30 , what do volvo recommend in the states ? just wondering thats all .

Sheer folly to try to compare modern full synthetic motor oil to the oil that was available in the last century. Evolution happened. I have used 5w-30 (maybe it was 0w-30?) in the past. That photo was just what I found in the garage yesterday.
