Hey everybody, new guy to the forum just joined today. To Ken on the Delo 400LE I have used since 1st oil change 2011 Venture bought new in 2012. 12.000ish miles on the bike now no problems. I also used in my 1981 Goldwing 96,000 when I sold it. As far as I can tell The LE stands for low emissions for the new diesels.
