ok so there is a big thread on s2ki.com about lubrication engineers LE1605 being no longer rated as a GL5 gear oil. there are a few people who are thinking its mainly for marketing but would like to see if anyone knows any more info on it HOPING INDYMAC will chime in on here! here is the thread https:/
Just off the phone with Lubrication Engineers minutes ago. Guess what? LE-1605 no longer marketed or labeled as GL5! There's a new formulation and new bottles. Sales had Engineering call me.
After a few minutes of pleasant conversation it was determined they do have a couple of GL5 hypoid gear oils. LE-703 80W-90 grade is available in quarts for $26.54, about the same price as 1605. LE-704 85W-140 is only available in a pail as the smallest unit.
I did confirm that the new LE-1605 is the "functionally the same stuff" as the old albeit in different bottles according to the engineer but they now neither list it as a GL5 nor market it for automotive use. I have a couple of bottles of the New LE-1605 as well as some Amsoil. Decision time in a couple of months.
anyone know where we could send 2 sample, of old version vs new version to have tested to see if in fact they are the same fluid and they are just doing it for marketing?? will Blackstone do this? www.s2ki.com/ forums/ s2000-under-hood-22/ diff-oil-weight-recommendation-2018-a-1188044/
