not sure about the wd 40 not mixing well but there must be something eqivalant to klotz lube. maybe someone else could chime in. i just got a full bottle of klotz lube from smc .it will probably last me forever with all this freaking rain were having.
I don't use any lubricant in my mix. I've only had my diy kit on for 3 years and 70,000 miles. How long do you think my pump will hold up? Am I in trouble?
