They work.
I liberated these from the guts of some hard disc drives.
I recently ran 1L of Castrol Spagnatec (10W-40) with 1.5L of GTX2 (20W-50) because i ran out of GTX2 and i had the Spag lying around... after a run at 100kph in some high 20-degree weather with no deck lid stand offs, my engine started to overheat and ping like a muthabitch.... *let the angry cars and buses past while i pull over* I've got a small leak from my pushrod tubes that don't normally give me much trouble, but now with the thinner (and very hot) oil, i could see it dripping out onto my heater boxes and smoking quite visibly..
so i left the engine idling to cool down the engine while i fitted my Hoodjax.. after that, the engine stopped pinging 🙂
Anywho, after 800kms, i dropped the oil coz I didn't want a repeat of the overheating. The oil was pretty dark, esp for 800kms. And this is what was on the sump plate after i washed the oil off the plate:
I wiped the magnet on the right side to differentiate how much crap was on it..
