Part 1:
Words, almost, fail me. Quite apart from the cringe and vomit-making
comments about 'amazing your friends with your warp gear' are we really
expected to have any confidence in the technical ability of someone who
writes "Shift *in* (my emphasis) to overdrive and then accelerate into the
great beyond"? This person hasn't the faintest idea what he is talking
about. I can't believe that anyone would use one non-standard oil and say
that because it gives higher pressures than the recommended oil it must be
better, then try another and say because it gives even higher pressures it
must be bad! The author is simply using the facts to suit his hypothesis,
something which science does all to often these days. Does he really think
Laycock designed the overdrive without knowing the pressures using engine
oil? The Leyland Workshop Manual gives pressures of 540 to 560 psi for the
D-type OD, 400 to 420 for the LH in the 4-cylinder, and 510 to 530 for the
LH in the V8, which is specified to use 90 gear oil. These pressures are as
a result of the relief valve opening at the design pressure, they aren't the
maximum possible that the pump
generates. The higher pressure in the V8 compared to the 4-cylinder LH is
down to different relief valve and clutch springs. Did they try 20W/50?
Even 15W/40 is like water by
comparison, let alone 10W/40. One could say the author was writing about
A-type overdrives which may well be different
to D- and LH-type. If they are *that* different then at best the article is
irrelevant to any other type of OD, but given the other statements it is
utter rubbish.
As for people here it is all 'might' and 'could', doesn't the fact that tens
of millions of miles in millions of cars worldwide with negligible problems
count for anything?
