when it saves a $600 of nikasil plating and piston its worth it.
Yes and no there Jeram.
I think most of us have no problems when using good quality oils.
If a ring decides to brake or a locating pin comes out of the piston it doesn't matter jack what oil you use , your nikasil is gone.
Just saying.
yes but thats about as relevent as saying, if your backwheel falls off will your premix save you.
both are unrelated to premix.
but where good oil comes in to save your barrel is when the piston gets very hot and expands to the point where you have very little or no clearance between the piston and the bore
at hot temps, synthetic oils simply vaporise and all their lubricating properties are lost, but racing castors form even more complex esters at high temps. So the hotter your engine runs the more lubricating capacity castor oil has which is reverse proportional to synthetics.
Add some castor to some synthetic and add a dash of super slippery ceramic additive and you get a very nice oil that gives you the best of both worlds.
1. cleaner running and less varnish due to the synthetic, great lubricating properties for low temp running
2. high temp protection when you need it thanks to the castor
3. reduced friction due to ceramic additives when you really need it (seizure time)
