I found Castrol GT-LMA at Advance Auto Parts (formerly Western Auto then Parts America). The guy brought it up in his computer that they usually stock 4 bottles. I bought all 4 and I plan to go buy another 4 when the next shipment comes in (Wednesday). They come in 12oz bottle and run about $2.80 a piece. I flushed and bled my system today and it took less than two bottles so don't worry about needing a whole bunch of it. If you can't find it anywhere, email me and I'll send you some at cost + postage when the next shipment comes in. gatewayaag *at* mindspring.com Good luck, --Jonathan #000697
