I have a toploader and want to change the fluid and bought some Pennzoil SAE 80w-90 GL-5 multi-purpose gear lube.But before I put it in, I am wondering if anyone else has used it and liked it or if I should use it? I wont use a
synthetic oil in a toploader that was built in 71 back when
synthetic oils were just a wet dream. Any thoughts would be great before I change my fluid
