Freon is a Dupont trade name for their refrigerants.

Yes and no... Freon is a name trademarked bu DuPont for their line of CFC and HFC refrigerants... so it's not actually Freon unless manufactured by DuPont and marketed as such. Not all refrigerant is made by DuPont, and not all refrigerant is of the HFC or CFC type.
"Freon" is a registered trademark of DuPont - thus, DuPont is the only brand of "Freon" there is. If you're asking what type of refrigerant, the XL7 entered production in 1996, by which point, it was mandated that automotive systems use R134a refrigerant. It can be from another manufacturer - it's doesn't have to be DuPont brand.
What is used in vehicles is called Refrigerant, freon is just a brand name used by the DuPont corporation. .......
Your 95 Saturn takes R134a refrigerant (freon is a trademark exclusive to DuPont brand).
Freon is DuPont's trade name. There are 2 types of Freon, Freon-11 is trichlorofluoromethane, while Freon-12 is dichlorodifluoromethane. All types of Freon have been banned from production since 1996. Refrigerants are manmade compounds not Elements
None as there is no Freon in a 1996 vehicle. This vehicle uses R134a refrigrant instead of R12 Freon. The amount needed depends on how much is missing. The proper guage is used to determine how much to install. I suggest you have it installed by a professional. Actually, "freon" is not exclusive to R12 - "Freon" is a name trademarked by DuPont for a range of CFC and HFC refrigerants manufactured by them (including R12 and R134a). So, technically, it's Freon only if it's manufactured by DuPont and marketed under that name. Your tracker requires 21 ounces (just a hair less than 1.32 lbs) of refrigerant. Not really wanting to debate the issue because it is a mute point but R134a is not called Freon by Dupont. Freon is dichlorofluormethane and is referred to as Freon 12, R-12, or CFC-12 and has been banned. R-134a proper name is tetrafluoroethane. Dupont calls R-134a (Dupont SUVA R-134a Refrigrant). It is never referred to as Freon because it is not Freon. So I stand by my original statement.
All vehicles after the mid 90's use 134-A refrigerant. "Freon" is the name of a specific product, originally manufactured by DuPont. When the patent on Freon expired, DuPont introduced 134-A.
A 1997 model year vehicle would use R134a refrigerant. Freon is a registered trademark of DuPont for a line of CFC and HFC refrigerants they manufacture and market, so it's not actually Freon unless manufactured by DuPont and marketed under that name.
