i only have 2 quarts, i will drain whatever is in there, add both quarts, then maybe get another to top it off? I guess we will see shortly i will be on thisI run Penzoil synchromesh in all of my VW’s manual transmissions. I tried the valvoline and wasn’t as happy as with the Penzoil, and I’m a valvoline guy from way back.
I had been using OEM vw transmission oil but I was getting a notchy 1st to 2nd shift with a little grinding that was driving me crazy. I was about ready to look for a transmission when I thought I’ll try one last time and changed to the Penzoil and no more notchy grinding 1st to 2nd shift.
I would change the entire transmission oil, don’t just top off. It takes almost exactly 2 quarts, and as I pointed out earlier I keep the front slightly elevated when I fill so I can do a slight overfill. Better to much oil as opposed to not enough leaving that 5th gear high and dry.
Two quarts of Penzoil synchromesh at my local Napa is about $20 plus tax. $9.99 per quart vs about $20 per quart for oem fluid.
