The other oil that interests me is the Nulon High Protection Diesel Oil 15W - 40 which you can get in 10 litre containers for about $60 , its been formulated for cold start diesel engines so provides better protection at lower oil temperatures

SAE Viscosity Grade 15W-40
KV @ 100°C (cSt) 15.00
KV @ 40°C (cSt) 109.0
Viscosity Index, ASTM D 2270 143
Density @ 15°C Kg/l 0.8834
Sulfated Ash, wt%, ASTM D 874 1.35
Total Base #, mg KOH/g, ASTM D 2896 10.00
Pour Point, °C, ASTM D 97 -24
Flash Point, °C, ASTM D 92 225

The first time using it would probably mean a shorter period of time before the next service as with the detergents/ additives it would clean out some carbon

On the Nulon site it says its ok for petrol engines so I might try it with the next service just to see how it is

What is the current oil to be used? I have only just gotten back into Mini's from about 10 years ago and that was around the time that leaded fuel was just phased out and everyone was changing to hardened valve seats.
I have a 1310 eng that was built 18 months ago. It was run in with mild use for 6 months before I bought it and have been building it up for 12 months. I need to do an oil change before I start driving.
What is the current options? What is everyone using?

G'day Eenii Meani , not sure how long you have been checking out Ausmini for , but there has been Sqillions of conversations on what oil we should be putting in our mini's,
everything from sheep dip to mollasses , so have a bit of a search and see what you can find , but on a personnel note , i use Castrol Edge Sport 25W - 50.

I always keep a look out for castrol Edge and only buy it when on special , i think the most i've paid for it is $35 , at Repco , pays to look around .

+1 molasses




Smells like something you can eat! But oh the price! Did I see it for 49 at Supercrap the other day?

There's a couple of other brands with oils aimed at our old skool engines. The Valvoline XLD Classic is 9.95 at Autobarn at the moment.


Mobil also has a product for us:

Penrite like many other company's out source their oil recommendations, in fact you are re-directed to a different website when you click on oil recommendations. So you could have made that remark about castrol, valvoline, BP, mobil or any other number of company's who use the same oil guide.

EDIT: to sound nicer

It is only since they out sourced the data that they got it right. When it was wrong it was on the Penrite website.

So, sue them.

You should put your heart & soul into everything you do.

I gave up on Penrite's oil years ago:
HPR30- lost oil pressure when hot on the freeway (just like GTX does).
HPR40- gave me sludge in the rocker cover (even with PCV system working) even though my change interval was only 1000 miles.
HPR50- (which is a 40/70) I put in my son's 998 oilburner Clubby once, in winter, it was so thick that it stuck the primary gear to the crank- he couldn't get gears!

re the Valvoline XLD Classic mentioned above- I find the oil pressure is great when hot (no cooler fitted)- pressure is even better than KMX was.

As for the Castrol Edge Sport 25W/50- IMO it's fine oil but they have lost me on the price. For a road car, it ain't that good.

I have used Castrol GTX 20-50 here in North America for years. Yes, oil pressure will fall with engine temperature rise - thus oil cooler and extra radiator(for the hotter weasther) to keep coolant and oil temps OK. Works here....worked on One Lap of Australia.

I know 27,000 kms/17,000 miles over 4 months from frost in Glen Innes in mid-August to 40-45C crossing from Kununurra to Broome Oct. 11-13 might not seem to be an adequate field test...but no engine overheating and no oil consumption - well 1/2 pint over 5,000 kms/3,000 miles between oil changes.

I used Castrol GTX twice and Shell 20-50 the rest of the way...Shell was almost always on sale as we went around. Key words we don't see here "For Older Engines".

Original 1098 short block with unleaded seats in head, Van loaded with gear etc. etc.

With stop/start driving over shorter trips, I change oil every 1,600-2,400 kms./1,000-1,500 miles.

I guess it shows that with a "sympathetic" driving style and a properly tuned engine makes more difference than anything else!
