Review: Seems to have worked well. - Did a complete vacuum and refill of my 2012 Focus system and as it hadn't worked for ages, used this stuff to lube the system before refilling the gas. The system now works well and quietly so I guess this did the job. I followed a really useful Youtube video on how to do the job and how and when to apply the oil and wrote a proper instruction sheet for future reference.
Review: Does what is says on the tin - Good quality oil has the tint of green so you can spot any leaks

## Questions & Answers

**Q: Is this suitable for car air conditioning that has r134a already in the system?**
A: Yes, it's suitable, but you need to find out how much to add to your system. Most oil is held in the compressor so if you're changing the exchanger for example, I'd be inclined to add very little and just lubricate the o-rings on the inlet/outlet.

**Q: is the liquid compressed and can it be applied with the same hose as the refrigerant topup?**
A: No the liquid is not compressed, I poured it into the compressor direct as I was fitting a new one at the time so not sure if you can pour it in to the refrigerant topup hose.

**Q: Can this be used instead of Denso ND OIL8?**
A: The answer is no.

**Q: Does this come with hose or figments**
A: Not sure what you mean by figments but is tin only
