I use this in a 2008 Nissan Rogue SL AWD with 235,000+ miles on it and have used it in the transfer case and rear differential since it's first gear oil change from brand new. Still looks clean after 30,000 mile change intervals. Also use it currently in a 2008 Nissan Titan front axle, 1995 Nissan D21 pickup rear differential and farm equipment gearboxes, all at 30,000 mile or 2 year change intervals regardless. Moisture and corrision reduction and piece of mind. Exceptional gear oil that does what it's supposed to do. Lubrication, Protection and Longevity. Valvoline Synthetic gear oil is even better I'm sure. I just don't use Synthetic gear oil unless required by manufacturer. This conventional stuff is just as good!

I often use Purolator oil filters and I always change my own oil. My auto has just turned over 200,000 miles and basically all I do for maintenance is change the oil and filter every 4-5,000 miles.

Works as advertised and then some. Very good product! If you want it pressurized they do sell it but it's not refrigerant coolant! If ya want refrigerant ya need a gas like R-134A or more specifically whatever the refrigerant the system calls for! Check manual or for labels by the dryer or check valves, evaporator box, etc. under hood...
