I poured out some Lubricin into a clear glass container and I did not see any flecks.
Randy, what do you mean by "be careful?"
Can I harm my engines if I use this stuff as an engine detergent. On the can, Sig sated that they used 2% Lubricin in all of their fuels.
Stay well my friends,
A very big chance You WILL have problems with Lubricin, especially with castor fuels, i would never use it with castor, and synthetic doesn't need it, I doubt SIG has used any lubricin in their fuel in decades
