im considering switching all the vehicles i have to shell rotella synth-
5w40. 2 vehicles spec 5w30, and 2 spec 10w40. i figure 5w40 will be a
happy compromise. any reason not to, other than it not having the
"energy conserving starburst" label?

My '96 Odyssey started the "slap" at about 40,000 miles. It was always
treated to Mobil-1 oil changes at 3000 mile intervals. We were religious
about proper warm up, etc. I don't think the oil makes any difference.
Some of them do it and some of them don't.

For my next oil change, I'm going to switch to Mobel-1 0w40. If it
returns the same gas mileage as the current Mobel-1 5w30, it's going to
become my summer oil (and I'll switch to 0w20 for the winter).

Considering that the 96 Odyssey was Honda's first attempt at making a
Minivan with Isuzu help, it could have some reliability issues. 40,000miles
seem extremely early for 'piston knock' to occur. If so, it should have been
a warranty issue.

i repeat what i said earlier - some of this /definitely/ depends on the
oil. i changed the oil on my civic this weekend, and she went from
being borderline rattly to utterly quiet. castol gtx 5w-30. 5k miles
since last oil & 10k since last filter. the change before the last
filter was motorcraft 5w-30 & she made a noise like a bag of loose
rattly things from day 1 [and leaked oil like crazy]. with castrol you
get a few thousand miles before it gets noisy, and you need to leave it
in there a /long/ time before it sounds like the ford stuff.

motor oils are /not/ all the same. they /do/ effect how the engine sounds.

how much did isuzu actually "Help"? isnt it pretty much a standard
accord platform, with a minivan body? i know it was branded as the isuzu
oasis, but i really dont see any isuzu in the design, unlike the
passport, which was a simple rebadge.

I don't think that Isuzu had any part in engineering the Odyssey. The
only connection with Isuzu was that they got some Odysseys to rebadge
(Oasis) as part of the deal that gave Honda the dreaded Passport and
some equally forgettable SUV for the Acura line.

The original Ody was based on the Accord platform and the piston slap
is an occasional problem on a number of Honda models of this vintage.
The first generation Odyssey actually had better reliability than the
second generation minivan.

the SLX/trooper! and youre right, i totally forgot about it.

kinda sad to see how isuzu practically doesnt exist in the states any
more. in their heyday, they had a wide range of smaller, useable SUVS,
along with the amigo, and a decent minitruck. now? nothin but a rebadged
GM clone.

i live close to the cerritos auto square in southern california. on the
main strip are all the important dealers. off to the side is a converted
paint store that now sells isuzu/suzuki/mitsubishi. none of those
marques can afford to stand alone. i call it the "kiss of death"
dealership. before that, they sold daewoo

What is it about Castrol that makes it such a favorite with Honda
service centers? I mean as log as -- say -- a Chevron brand oil has the
same API rating that is specified by the Honda specs it should make not
diffeence, should it? Yet I noticed that the Honda shops always uses
Castrol.

Was that after the Yugo shop closed?
