When our cars were made there were not, to my knowledge, oils intended to be used specifically for manual transmissions and in any case we wound up with the specification that 30 weight engine oil be used in gearboxes. )Maybe that is the best product that had been developed and maybe it was simply considered to be convenient to have the same product in both engine and gearbox, or both/)</div><div class="gmail_default" style="color:rgb(51,51,255)"><br></div><div class="gmail_default" style="color:rgb(51,51,255)">I don't know when detergent oils were first developed but I don't recall that they were commonly talked about or recommended "back in the day". And whether because detergent oils tend to keep stuff in suspension or because they contain less oil by volume than non-detergent oils, or both, they are usually not recommended for transmissions,.</div><div class="gmail_default" style="color:rgb(51,51,255)"><br></div><div class="gmail_default" style="color:rgb(51,51,255)">In any case oils have changed drastically from the early days of motor cars and I think that the best oils for us to now use in our transmissions, whether OD nor, are those specifically intended for them such as MTL, MT 90 and like products. I know from experience that MT90 gives me better/faster shifting.</div><div class="gmail_default" style="color:rgb(51,51,255)"><br></div><div class="gmail_default" style="color:rgb(51,51,255)">End of rant--Michael Oritt </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 26, 2015 at 7:11 PM, I Erbs <span dir="ltr"><<a href="mailto:eyera3@gmail.com" target="_blank">eyera3@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">We always out 30 wt non detergent for in the gearbox back in the day.

<div>Ira: In the Driver's Handbook for my BJ8, the table "KEY TO
RECOMMENDED LUBRICANTS", column A, Engine and Gearbox, sub-column Tropical and
temperate down to 5 degrees C, 41 degrees F, after all the single grade oils,
the recommendations include Shell, Mobil, and ESSO 20W/40; and Filtrate and
Duckham's 20/50. In the extreme cold, down to 12 C, 10 F, there are
10W/30, 10W/40, 20W/30, 20/50, and 5050 (no slash ?). Some of those were
not available in the United Kingdom at the time of publication and some were
available in the UK only.</div>

couldn't find the instructions I have somewhere)</div>
