Hi my name is Dave and I'm new to the Town Hall. I
really enjoy the discussions on this site.
Anyways, my question comment is are Synthetic
Differential fluids worth it. I'm thinking of going
with Redline. My other question is what is the
best spark plug. My understanding is that for
European/American cars/trucks it's Bosch or
Autolite, NGK for Japanese and Champion for small
engine. Splitfire I hear is total garbage. Thanks
for all help and I hope this topic isn't redundant.
