Abstract
A fleet test using Propylene Glycol (PG) based coolant, recycled PG based coolant and PG mixed with ethylene glycol (EG) coolant was conducted using a fleet of employee vehicles. These coolants were all formulated using extended life, silicate free additive technology. This fleet consisted of a wide range of vehicle types and was run to verify the effectiveness of utilizing a PG based coolant across a broad spectrum of vehicle types. The results from this fleet test will be discussed. Results will include coolant analysis, parts inspection and vehicle repair histories. The environmental (toxicological) benefits of such a coolant will also be discussed.
