Thanks for all the advice. I = bought Mobil1 15w50 for my waterboxer. I live right on the VT,MA and NY = borders. I grew up in this area and remember it getting really cold. The van = won't be garaged. I'm thinking that it may be a really good idea to install = a block heater. It's not going to be driven every day, but there when I = really need to. I also bought 80w90 gl-3,gl-4,gl-5 for the gearbox. = Next weekend I'm changing the clutch slave cylinder, master was done 12k ago.
