Compatibility of VpCI™-705 with Jet Fuel

Background: GM Canada would like to use VpCI-705 to protect fuel tanks as an additive to Jet Fuel.

Purpose: To determine if VpCI™-705 is compatible with JP-8 and DF-2 Jet Fuel.

Materials: VpCI™-705

JP-8 and Pseudo JP-8

DF-2

Additives: Biobor JF (Biocide), Select 3 (Diesel Fuel Conditioner)

Method: Standardized Compatibility Test

Procedure: The following solutions were mixed:

Sample Name	Base Fuel	VpCI-705 %	Additives (% of each)
A	JP-8	0.12	0
B	Pseudo JP-8	0.12	0
C	DF-2	0.12	0
D	DF-2	0.12	0.020
E	DF-2	0	0.020

The solution was mixed thoroughly and placed inside a refrigerator for 8 hours. The containers were then placed in an 80 °C oven for 16 hours. The samples were inspected when moved, and this cycle was repeated three times.

Results: The following data was taken:
