I went to EZ Lube and I did get a gear lube change. However, I looked under the car myself and I saw something imprinted that says "use 75W90 Synthetic Gear Oil Only" or something of that matter. I wasn't sure if what EZ Lube put in was 75W90 synthetic, but I went to Autobacs recently and saw that all their 75W90 gear lube are all synthetic.
My question would be does 75W90 gear lube only come in synthetic? Or is there such thing as conventional 75W90 gear lube? I'm only asking this because in the store I went to, I saw nothing of conventional 75W90 fluid.
