Syn 3. Is good,
Penrite every time. HD don't own oil factories - Penrite gives Australians jobs. We have nearly fucked or sold off every old Oz industry. Support the one's left that are still Australian owned and provide a world standard product.
I have been using Penrite of late myself , in my own Harley and all my mate's bikes. You could say I am now a "convert" !
MC 4ST 10W-60 in the engine oil tank AND Primary drive , comes in 4L , PRO GEAR FULL SYNTHETIC 75W-85 in the transmission, comes in 1 and 2.5L.
I get it locally , and on 20% off days and the like , from Supercheap Auto 5 K's from the house.
In the past I have used Mobil 1 ,and/or Redline ( hard to get in WA now since Coventry's stopped carrying it on the shelf !)
For the same "local" reason I have been using Penrite in my V8 Commodore motorsport and my daughter's 2016 Suzuki 4 cylinder.
That's 5W-40 ENVIRO+ DEXOS 2 ( necessary for Holden/GM new car warranty) comes in 10 litres , 7 in the Commodore and 3 in the Suzuki !
I run the local fish & chippie and am a recycler, so it goes in all 3 holes once I'm finished with it in the kitchen,
The springer loves it and it has a lovely after smell when cooling down.
Vic you bin' drinkin' the Ethanoic acid ( VINEGAR!) in the fish'n chipper AGAIN ?
Remember it's a 50:50 blend with Mundaring Weir dam water !
