au oil

[HARMFUL 81]

without trying to stir up a hornets nest, what type/grade all should i use for my au3. Its the family taxi with 185k on the clock, regular towing.

[JoesAu]

Fuchs or Penrite!!, best stuff ive used!!
Im currently at 175k, im using Fuchs perfomance 15/40, best oil ive used! its about $40. Penrite a little more. The stuff has lasted ages and still has good colour, motor not noisey. i'll never use shell,valvoline, castrol, there all rubbish

[EvilChief]

first of all id asked where do you live, the weight of the oil depends on your weather conditions

[V8falcons]

I use magnatec 10-30,on both our AUs,no problems

[The Monty]

I use a 10W 30, 256 000 k's.

Chief raised an important consideration.

I'm in Melbourne. Both AUs are on LPG. One (my daily driver) is a S2 SR Sedan (124,000) the other and older (family bus) is a S1 Futura Wagon (175,000), so the wagon is pretty close to what your setup is.

I've used Magnatec, but it always came out very black and runny, particularly in the wagon. Tried Penrite HPR10 Gas next, which was also good, but the engines in both were still a bit rattly.

Tried shell 15/50 which was very good for the dollars, but the engines were still a bit rattly!

On the SR, I've recently switched to Penzoil 10/40 and so far so good. Engine is quieter, but I'm yet to change it, so we'll see what it looks like when it comes out. The wagon still has a few thousand kays to run on the Shell 15/50 before it too makes the switch to the Penzoil.

That is of course my experience with my AUs. Many here would swear by the Penrite oils and in particular the HPR10 or HPR10 Gas if you're on dual fuel.

Whoosha posted an awesome link a while ago on a massive oil comparison, which had me looking at Valvoline dura blend, however I couldn't tell whether or not it was good for LPG, the bottle and website didn't say, so I left it. I was about to buy 3 bottles as SuperCheap had 20% off last week.

Here's that link.

[Jason[98.EL]]

would like to know where the oil i use fits into the line up

its moris oil semi synthetic 15/40 from memory

and the link to the company that makes the oil
http://www.morrislubricants.co.uk/
and my el has a hybrid e-series /au engine in it

That article was defunct as useless.. I'll link the details when I have a moment.

Taken from another forum.

Re: Oil Test by Street Commodores Magazine
OK, I had a lengthy chat with our Chemist to day over the way this test was run.

They talk of using the Falex machine (as pictured) then they talk about the type of test the Falex machine is famous for, being the “Timken OK Load” test. This test is used to show film strength in greases and sometimes gear oils.

When we got the bibles out and went through the procedure for the “Timken OK Load” test, it didn’t resemble SC test very much, in fact, as SC stated on their first page, the “Timken OK Load” has no wear scar showing.

To cut a long story short, with the oil at about 38.8C you load the machine in 6 pound stages for 10 minutes at a time until the machine breaks through the film of oil and starts to scuff the surface of the metal. The test is then stopped and repeated at 3 pounds less, if there is now no rupturing of the hydronamic film ie, no metal to metal contact, this is the “Timken OK Load”.

So the summing up of this test means running of the machine with the heaviest weight for 10 minutes, without any metal pick up is the “Timken OK Load”.


The photos show large wear scars on several of the bearings, the test should have been stopped and adjusted so all the bearings looked like the Penrite / Royal bearings and the difference between the oils would be the loading in pounds (not psi) without a wear scar, this would be somewhere between 20 and 70 lbs Timken OK Load.

As there was bugger all guide lines as to oil temperature, length of test in minutes or even the ASTM test number that such a test can be compared to or checked against, one has to say the results are not reliable enough to make decisions on which oil is better.

I may be able to get hold of the actual test and post for all to see.



It is very hard for a test like this to simulate running conditions, you really need to run the oil for 5 to 10,000 klms then carry out ppm for oil condition and Filtergram wear metal analysis. Then change to the next oil and run under the same conditions then you have a real test. If you compare the results of the 3 Filtergrams on page 2 of this post, that is a real indication of wear sustained over a distance. Things like heat and contamination (the biggest killer of any machine) take there toll in real situations that don’t show up in lab tests.

The "Timken OK Load" test procedure I have referred to above is the ASTM D2782 test

I use workshop-only Castrol FMX 15W-40 in my 643k old falc. loves it.

[blueoval]

If your running LPG, I recommend Penrite Gas10 10W/50 semi-synthetic.

Otherwise if your using petrol, top recommendations on my list are Nulon/Penrite or pennzoil.

GK - with the penrite gas10 I found my engine was rattly only when starting the car up after it was driven. But after a little while the lash adjusters would settle. Is this what you found or was the rattling more consistant despite the temperature?

+1. I have used it for years and never had any issues.

[Mechan1k]

Shell LPG 15W40 ... change every 5,000km ... no problems ... cheap ... clean ... no noise ... does the job (and the work ute gets a hell of a lot of work).

interesting test , even going by the the friction / amperage draw seems to be a decent indication of a decent oil, i`m more interested now to see a more detailed test if there is one, on a side note my mate has been talking up penrite oil for years , i just called him a silly old bugger.....it appears i might be eating some humble pie :(.
