What's your vote for the better oil for a GU 4.2 turbo diesel out of either Dello 400 or Shell Rimula Super C14?

Pick another if you think it's much better but at the same price.

Thanks all.

Can't comment on the shell, but have used the Dello for a few years in old 60 and tractors and very happy.

this sort of question comes up often here!
If the oil matches the specs for your engine and is of a reputable brand, then the cheapest one is the best by far.

Honestly, if someones engine blows up 5 minutes after changing to one of these oils, it DEFINITELY wasnt cos of the oil.
There is no measurable difference between any of them, no matter what they say in advertising.
And it matters not one iota changing to a different brand of oil after using another for a long period.

In the following order

1/ Correct grade and spec

2/ Reputable brand

Delo 400 is made to US Milspec. I used to run it in my Chev 6.5 for this reason.

I used to get it dirt cheap in 20l drums from an Ampol sevo in an industrial area. Can be hard to find at the right price elsewhere.

Good oil is cheap insurance.

It is interesting how a slight change in the make up of the different grade oils changes the what happens and I am not talking big differences like between series 2 and series 3 oils.

I was told to use delo 500 15w40 in my 6.5l diesel. I didn't notice that I had been given a drum of delo 400. The engine started to use oil (not a lot) and leak from the rear seal. I noticed it was the wrong oil and changed back to the 500, result all the problems disappeared. Another guy I know has the same engine and was using shell rimula and having the oil use and leaking problem, he changed to the delo 500 and problem gone.

Nothing wrong with the delo 400 or shell rimula, they just didn't suit that engine.
