Yeah. Last time I got it through Supercheap Auto who charged me freight to order it in. They should change their name to Notveryfuckingcheapatall.
Found a different supplier, Sparesbox Auto. I still have to order it on-line, either directly from Sparesbox or through their eBay shop, but delivery is free.
Still haven't found anyone who stocks the stuff on the shelf here in Hobart.

Do you want me to get any?

@ Vince. No problem mate. Got plenty of MC4ST.

Sorry Cam I thought you already had. Grab a 4 litre bottle for me, the others are sorted.
Cheers

OK. Done. Just placed an order.

None of the local bike shops stock Enduro (or Enduro HD - same thing, just a new name). I thought the Harley guys might have had some, but no, they only stock Motul oils.  Supercheap only has it in 20 litre containers. Had to order a 4 litre container on-line for $62.95 (slight increase since I last priced it in July). Should be here in a few days.

Not wanting to start an oil thread, but what's the reason for using 25W-70?  That's quite a thick oil. You must have a rattly old engine  ;) 

I use 20W-50 (Penrite MC-4ST). Got plenty of that on the shelf.

I think you just started an oil thread......

I used to work for Penrite

Try this experiment Cam, pour some oil into a pan, put it on the stove and heat to 110 degrees. Then see how “thick” it is

Yep, I'm aware that oil gets thinner when hot. That's what the 50 bit of the 20W-50 designation means. It has the viscosity of a 50 weight oil at 100°C
The 20W bit means it has the viscosity of a 20 weight oil at -17.8°C (zero Fahrenheit).

The 70 oil will be a bit thicker than 50 at the same temperature, but is that necessarily a good thing? Higher viscosity may mean you get less flow, which could reduce the cooling effect of the oil.

If you get less oil going through the oil cooler, it'll run hotter. That extra heat will reduce its viscosity further. So your 70 oil may end up with similar viscosity to 50 oil because the engine is 10° hotter. I dunno whether that actually happens. I'm just speculating.

Vehicle manufacturers specify a certain viscosity of oil to be used in their engines. If thicker is better, why don't all vehicles run SAE 90 oil in the engine?

whilst this is not the calculation...:  viscosity * orifice = pressure! 

I don't know the pressure capacity of a Laverda oil pump or oil gallery orifice dia/lengths, but on cold starts, that thick oil may not be reaching where it supposed to be...initially!  maybe you need a sump heater to lower the oil viscosity!  :laugh:

Guys in the white coats in the lab at Penrite told me that was the best stuff so I have used it from 18000km to currently 86000km. Transverse is also correct if it runs through the oil cooler too fast it doesn’t get to cool down.

Supposedly mineral oil will dissipate heat better than synthetic oil, ran my Rgs to 200000 km on Penrite was getting a bit smoky towards the end

Don't recall me saying Penrite wasn't any good…. in fact I have been using HRP30 20/60 since owning my Jota.  No problems - real good shit!!!

but high Viscosity oil is 'harder' requiring more pressure to flow through small orifices.....that's all!
