R134a Automotive Air Conditioning Compressor Oil – PAG 46H (1 Litre)
This 1 kg r134a compatible PAG oil immediately caught my eye due to its clean packaging and the claim of “high lubrication performance.” I ordered two bottles — one for my Subaru Forester and one for a customer’s Toyota.
Delivery took around three weeks. When I opened the bottle, I noticed the oil was crystal-clear and odor-free — a good sign. It blended smoothly during vacuuming and recharging. After two weeks, both cars’ A/C systems ran whisper-quiet.
Pros: Good viscosity, transparent, no residue. Cons: Cap thread felt a bit weak. Verdict: For this price, it beats many local brands. One of the best 1 kg r134a buy options I’ve found so far.

After refilling with 1 kg r134a, the cooling improved drastically — from lukewarm to arctic blast in about 10 minutes of idling.
Pros: Protects seals, improves cooling efficiency. Cons: A bit pricier than others. Verdict: Solid performer for anyone who wants long-term reliability.
