RED TEK OilCharge A/C Universal Refrigeration Oil

My 1991 GMC has great air conditioning thanks to this kit. It may have had a leak so I threw in two cans of the refrigerant and the can of stop leak. It works great now. It did smell like propane and does say flammable on the can, so if you know you have a leak I would fix that first

I got this to add to my AC system on my old ranger. It works just fine. I just wish it was a little bit cheaper. But it was still well worth it to lubricate the system and not have to go and do a whole AC swap on my truck.

I used this on my refrigerator/freezer. It worked good!

Great product! Used this as a part of my rejuvenation of my 73 Blazer's AC system that had not ran in 15 years, it has been nearly a year, and I have 37 degree air at the vents! RedTek has definitely impressed me!

Brought the system to vacuum- (Advance Auto will "rent" you the gauges and pump for free) Left it sit at vacuum for a week, rerented the guages and pump- system was still at vacuum, so no leaks; but since I bought the leak sealer I put it in anyway. R12a makes my old Suburban a/c system blow ice cold! Charged with 4 cans of 12a, an oil charge, and the leak sealer. The heavy Suburban and a 5.7L engine with A/C on made me think that I'd have no power whatsoever, and fuel mileage would be more awful than normal, must be the lower head pressures because there's no perceptible difference in power of mileage.

Fine

I thought I had a product that was all lubricant, but the can showed it was only 2 of the 4 ounces in the can. There are cheaper and better products out there.

Great product. Works perfectly with the Red Tec refill kit
