Hey guys, my ride has started having issues going into gears cleanly. I hope it is just the gear oil. I have never changed it since finally getting her running so I expect it to be quite old. I got it all drained.
My question. Should I use synthetic or not. Back 15 years ago on posts, it read don't use but then I find others saying they are. I figured synthetics have gotten a lot better since then. I bought synthetic but having my doubts until I here some recent opinions. I purchased Synthetic 75W-90 GL-5 Gear Oil. 3 quarts. |

I've been using Swepco 201 in my transmission. Made an immediate improvement, and it just keeps getting better and better.
I have a buddy who swears by Redline heavy shockproof, but it is synthetic. |
