Killerdriver, is your dmax petrol or diesel? If its diesel i wouldnt use sport. But if its v6 that'd be good :-)

What alot of people dont know is diesel have huge soot handling and heavy detergent properties and a petrol oil can severely reduce your engines life.

i changed out my oil and filter on the weekend. I used Rimula r3x 15w40, its the first recommendation in the book after genuine.
I've found its much quieter but takes a couple of seconds to gain oil pressure.
Could the filter's bypass be faulty?
Is there a way to crank the motor without it firing? I know with some petrol cars you can hold the accelerator flat to the floor which cuts the fuel while cranking.

Using delo 400 in my ute, makes a hororble rattle for about 2 seconds on a cold crank but then runs fine, is anyone else get a strange noise immediately after cold start? Looking at trying other oils, super cheap have a 20l drum of rimula r3x so I mite try that next time, only have 11,500km on it.

I would get that checked, most engines can get pressure (to turn off the oil light) just with cranking - it could be the sensor but worth a look. Of course a filter change usually results in a few seconds of low pressure the first time, until the filter fills up.

As jazzeddie said, if you've just changed your oil and filter, the light will take a bit longer to go out than normal as the filter needs to fill up first.

Make sure you are running a diesel compatible oil. These days you can run a thinner oil and synthetecs too for modern oilers. I'm using an Australian made brand, Nulon, in full synthetic 5w30 for diesel engines.

As long as your oil light is going off fairly quickly when you start the engine I wouldn't panic. If it takes a while, 10-15 seconds, and you haven't just done a filter change, I'd start to check things out.

it takes about 1.5 - 2 seconds for the light to go out.

yeah, if it was taking 10-15 seconds I'd be pretty worried, and would've thrown the old oil filter straight back on for a comparison.

not surprising since you have gone to a 15w oil, so when cold it is thicker so will take longer to get to pressure

SSBB
Have you noticed the oil filter on a new Dmax is upside down when compared to the pre 2012 models?
Although the filter will have a, non return annular flap, (like a big flexible washer) to attempt to hold the filter full of oil when it is not running, nearly all of these rarely work and the oil will drain out of the filter.
At start up it will take slighty more time to fill it and develop oil pressure than pre 2012 models do. Just start it and let it idle until pressure is there.
To me this is a stupid way to mount an oil filter.
Also it has a fence around the filter cos when you change the filter you cannot prevent oil from going everywhere and it has a drain hole and hose to the underside of the vehicle, More to allow for and more to clean whenever a filter is changed.

Use to own an older Rodeo with an upside down mounting and found the genuine filter was the best way to go. Oil pressure came up straight away. Any other flter was not so good, even if it did have a non return valve in the filter, as it was usually at the wrong end of it. As SSBB mentioned it needs to be in the top of the filter.

On the oil- A 5W~whatever oil will flow faster and reach oil pressure faster at startup, especially when cold.

yeah i noticed that, i did do the oil change myself, and used a genuine filter (no aftermarket available yet).

the position of the filter makes for an easy change out, and I like the little drain hose for when you spill a little bit.

I also understand a bit about oils, and yes the Rimula 15w40 is thicker when cold, but its also the first recommended oil after genuine in the handbook, unless they are in some random order which I doubt. A 0w40 would be better i imagine but none listed in the handbook, and perhaps there isn't one in that rating which meets the diesel spec requirements?

Without an oil temp gauge in this vehicle I'm not 100% sure but i'm sure running a xxw40 would be better for mine as I carry tools, ladder and cable, toolboxes etc. I'm not sure on the exact weight of all this but i'm sure the engines working harder as I'm using more fuel now I'm loaded up.

The '0' or '15' as the first number can be considered a 'winter' number, or how well the oil runs when cold. The '40' number is the oils ability to work at operating temperatures. So a 0w40 and 15w40 will both be similar at operating temps, the first one better when you start up on a cold day.

isuzu also specs xW30 weights

since i changed to a 10W/30 i noticed quieter running and a fuel consumption saving

i noticed at operating temp the 40 is quieter, perhaps mine is running harder with a load and so the 30 is getting too hot and thinning out.

Fuel consumption figures are what manufacturers are striving for, and using a thinner oil must help in this regard.

And the Diesel Particulate Filter....

I read in a Repco cat of Castrol GTS 15W-40 CH-4 which states 'not suitable for vehicles fitted with DPF'.The Dmax book recommends CH-4 oil. (mine is 7/12 model)

I hope this means that the Dmax does not have a DPF. :irked:

If it does, I wonder can I later replace the exhaust to something larger when it is power chip time.....

I ended up getting 10 l of a repco oil 15w-40 Diesel CI-4. Gonna drop it at 5000k, not the filter. Will do again at 10k with filter ryco z600. :waycool:

i have an 09 dmax and was using nulon Full Synthetic 5W-30 Diesel oil but then a guy that use to work for an oil company told me how to read oil drums on the back is an API number it stands for american potrolium instutate check out there web site --
http://www.api.org/.../engineoil/.../mo ... 120210.pdf


if the oil has an api rating of cf like the nulon 5w-30 it is ment for deisels Introduced in 1994. For off-road, indirect-injected and other diesel engines including those using fuel with over 0.5% weight sulfur. Can be used in place of CD oils.
so i have now stoped using that oil and changed to delo 400 with a CI4 PLUS rating,
if the API rating is CI/SN it means it can be used for compression engins ( diesel ) - spark ( petrol ) .
the lower the second letter the more stuff in the oil to handle the soot that diesels produce in the oil

the link is not working so just copy and paste
