Filters WK2 Diesel

[SouthernComfort]

My own search for Rotella (in vain) was mostly in the early days of owning the GC. It was mostly based on reputation and write-up's and I thought it would be the best option for the diesel. Soon discovered that Penrite and similar brand variants are entirely suitable and I've been more than satisfied with Penrite ever since. The 'mystique' around Rotella quickly evaporated for me but I will admit to having looked for it now and then out of curiosity. Frustrating that there is no real supply line in AU making it a virtual non-option.

I once had a penchant for gear/diff oils by Liquid Engineering, brilliant stuff when you do lots of water crossings but price and availability made it too much hassle, thats back in the 70/80's .......... which reminds me I still haven't fitted some decent breather's to my diffs, I just stick some fuel line on and run it up high with a pigs tail end or old petrol fuel filter.

Just browsing the Repco site for what they have for my 2015 and spotted this oil filter I hadn't come across before. They say it used a synthetic blend media and looks good. Anyone used this yet?

What is it about the Amsol or Rotella that makes them stand out more ??..........

Hi drover...have been doing spreadsheets for a while now on various oils.

From my research; Shell Rotella has a TBN of 10.6. The higher the TBN or Total Base Number the higher the ability of the oil to neutralise contaminants / combustion byproducts. Which is what one wants if extending oil change intervals. (i change oil at around 5,000kms max so that is a tad irrelevant)

Amsoil has a TBN of 10.4...very similar. (Penrite Enviro+5w40 which is used by a number of owners, has a slightly lower TBN of 9.6)

On top of that the viscosity index of Amsoil is 175, Rotella 159. Interestingly the Penriet Enviro+ 5w40 specs read a VI of 197! The higher the Viscosity Index the more resistant the oil is to viscosity change in temperature movement.
Sulphated Ash is similar at 1% in both Rotella and Amsoil.
What I like about the Rotella is the specs read viscosity at 100c is around 14.2, Amsoil 14.6. Both Amsoil and Retella read a viscosity of 87 at 40c.
(Penrite Enviro+ 5w40 has a viscosity of 13 at 100c, 68 @ 40c)

I have found that some engine oils can be a tad slow to circulate on a cold start, though cold is like 25c here, the tappets can be heard chattering for a bit longer before quietening down as oil reaches them.
Fortunately oil goes to the crank first!

Cold cranking resistance for Rotella is listed as 6000, Amsoil 6075.
The Penrite Enviro+ 5w40 shoes pretty good specs as well with s ccs of 5340, lower resistance than the Shell and Amsoil in fact.

The Penrite Enviro+ 5w40 is a pretty good product, the only shortcoming is it does not comply in spec with the CJ-4 stipulated by Mopar for the VM Diesel...

I've got Penrite Enviro+10w40 Diesel Oil in mine atm, which is CJ-4 compliant, but it has a high ccs of 6600, and I reckon it too takes a bit longer to get to the top of the engine.

Hence my move to try out the Rotella...I like the specs.

Twisted like this, could be the reason behind it !!!!!

Just remember FCA in around 2016 mandated an immediate change from
5w30 to 5w40 because of engine failures in US Plus to get manufactures tick on the labels companies have to pay big money to the vehicle manufacturers.

It is a shame it is nigh on impossible to find what VM Motori would recommend for their V6 3L turbo engine.

We know manufacturers work on their own fortunes rather than the end user's. Hence I think the 5w30 recommendation from Mopar being upped to 5w40 in 2016 to include 2015 models, only I think as there would have been 2015 models still under warranty.

Though the engine was pretty much the same from 2011, so why not have suggested ALL VM Motori V6 engines changed to 5w30?
Or would that have opened a can of worms for potential Legal action from aggrieved owners who had experienced engine bearing failure previously?

I do find a measure of confidence in the basic engine being Gale Banks has been using this engine modified for Military use prior to 2011 when introduced.
