CamGuard Aviation Advanced Engine Oil Supplement (16 fl oz)

ASL CamGuard™ Corrosion Testing of Aviation Oils Aircraft Specialties Lubricants performed additional corrosion testing using the latest humidity cabinet testing procedure, DIN 50017. This is a worldwide reference test procedure showing both greater repeatability, test to test, and greater reproducibility, lab to lab, than the ASTM 1748. Tested were 20W-50 semi-synthetic (SS), 15W-50 semi-synthetic (SS), 20W-50 AD, W100 AD and W100 storage oil. Both semi-synthetic oils and the storage oil have corrosion inhibitor packages. This test is cyclic and uses distilled water. One cycle is 24 hours (1 day) and consists of 8 hours at 100% relative humidity (condensing) at a temperature of 122°F followed by 16 hours at ambient humidity at a temperature of 75°F. Matte finish sandblasted, SAE 1010 mild steel panels were used for this testing. The panels were dipped in the oils and then allowed to drip/drain for 2 hours. Figure 1 shows the average number of days to the appearance of significant rust on the panels. All of the oils show a remarkable improvement with the addition of CamGuard™. Moreover, all of the samples with CamGuard™ showed an impressive improvement over the long-term storage oil.
