ahh so says da blind man, i see your point....i do have some 20 wt non detergent i can try again, just to see if i get a difference till our buddy Lavoy gets me a rebuilt one, a bit pricey but if i can use my free 10 gallons of iso 32 in it then thats o.k.....but i did have the 20w in before i rebui...
