engine oil zd30 crd 10w40 magnatec or 15w40 magnatec
hi all,
im in need of engine oil and i ussually run 15w40 magnatec castrol.
no issues but i see castrol also say i can use 10w40 magnatec. only reason im considering this is cause its a good deal at the moment through repco.
these are my two options i was wondering what i should do?
would 10w40 be better for the engine or fuel economy? or are these oils too similar to notice a difference.
thanks

10W 40 will give slightly better performance in low temperatures on start up than the 15W40. Won't affect fuel economy one bit.

i live in central queensland i would say temps are hot more than cold, based on that im best to stick with 15w40.

Yes I would agree, however the top end protection which is the 40 is the same, so either would work really

Funny story...
When I bought my 2009 CRD. I had a years worth of warranty and servicing included at the stealership.
It's first service, I got told that wrong oil was in the car. Whoever serviced it prior, used 15-40, which was stated on the Castrol servicing sticker (windscreen).
And that I HAVE to use 10-40W.
I put it down to, either are fine... I think he was maybe trying to twist my arm to only use genuine (10-40) from the dealership.
Anyways, I always used the 15w-40 magnatec on my 3L AND my 4.2 after buying that. Never had an issue that I know of.

interesting, castrol site says non crd 15w40 is best but 10w40 is better
and crd engines is the other way around 10w40 is best but 15w40 is better
so following castrol and having crd i would go 15w40.. but hard to see why crd and non crd have different oil recommendations hey..
either way this time im going with 10w40 cause the price
i just did a service 2000km ago but im getting the timing cover oil/ coolant leak fixed this weekend will save the old oil and put it back in but ive been told to change the oil after about 50km in case there is any crap in it. so ill use the 10w40 and run that for 8,000km and then see what oil i can get my hands on.
im currious to see if i can see any differences when using 10w40 over 15w40 if i do i will mention them here.
im also cleaning out my inlet manifold so i will likely see power, performance and efficiency gaining from doing that.

Have always used 15W50 (Penrite HPR semi synth) in my car. The 15W is perhaps a bit too 'thick' down south (Ballarat) where I could travel several kilometres before the oil warmed enough to drop down to the 'normal' operating oil pressure of 58psi.
Currently in NW Kimberley where things are quite warm & did an oil change yesterday. Took the car for a drive for a few kms before dropping the oil, as is my usual practice, but found when pouring in the fresh oil that it was a lot 'runnier' than I have found on previous changes. Doubt I needed to take that pre-change drive. I see no reason to change to a 10W oil, at least not until I'm back in the cold.
Possibly of interest, earlier this year down in Tassie I found on several occasions that my oil pressure dropped down to 40psi when towing up some very long & steep mountains, but as soon as it cooled a little it returned to it's usual 58 psi. The fact that the oil had not been 'cooked' & that it regained it's usual properties after getting pretty hot was something I found quite reassuring.
