Premium gear oil
A premium oil that will probably last the rest of my old VW vans life. Same price as local major chain retailer.

Not bad, definite shift improvement. Good bottle design.
Used a few of these in a 2ZZ-GE Toyota Celica 6-speed 'box and it noticeably improved shifting feel. Smoother and more direct. Whether this was the oil itself or the fact it was changed I don't know. Well worth the hour-or-two to do the job. I used a hand oil pump but the bottle has a multi-stage lid that could be used to pour oil directly into a gearbox/diff if you have space, which is a nice touch.

High quality Castrol oil
I always use Castro oil in my vehicles from my motorbike to my truck. Have never changed transmission oil before so bought this and what a difference. For reference I have an old Mitsubishi l200 pickup truck so requires regular maintenance Oil quality is fantastic and has not let me down. For ease I also purchased a syringe to help refill the gear box and transfer case which made it much easier. I would never not use Castrol oil

Yet to be used
Purchased to change transmission oil as the noise had been diagnosed as a differential bearing whine; turned out to be a wheel bearing so this sits on y garage shelf. Prompt delivery
