Abstract: A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.

Abstract: A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to maintain fluidity in a low temperature environment and to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.
