Good thing my EU2000i doesn't have a sensor...or does it?

I have used synthetics since it was born.


Just a note on the EU series of Honda Generators: don't use synthetic oil
in them.  A tech at Honda told me he'd been seeing a lot of fouled oil
level sensors due to synthetic.  I guess something reacts with the sensor
and can make it give false positives (i.e. it shuts down your generator
because it thinks there is no oil).

It's a pain in the ass to change that sensor so although he said
synthetic was fine for the engine and the rest of the gen, it could screw
up that sensor which is the last thing you want to do -- believe me!

just a fyi

@newsfe04.iad:


Yes it does.  There is a little plunger like float switch in the bottom
of the crank case (thus it's a PAIN to fix - you have to tear down the
whole damn thing).
(see http://www.homebrewhydro.com/eu2000/eu2000_10_0014.jpg  chapt 10, 14
of the service manual)

Good for you though -- if it keeps working don't change it :)

Just like I was saying talking EU repares with the honda guy he was
talking about how a lot of new gens were coming back with faults in the
oil sensor switch.  Maybe it was just one batch, but the sales guys were
advised to tell new owners NOT to use synthetic.  Maybe it's mixing one
oil change with synth and another with regular that does it.. or maybe
honda fixed the issue.

Just know those boys were tearing down quite a few new eu2000 and eu3000
gens under warantee for those oil sensors and they wern't too happy about
it.

So if in doubt I'd avoid the synthetic just based on what those guys
said.

cheers

(btw: here are a lot of files related to eu2000i .. not the whole service
manual but the most useful sections.  the pdf shows how to change the
timing belt which is the usual cause for failure in an older eu2000i.  
Also a few pics of the wind turbine using the eu1000 Ulysses made
..pretty cool)

As David Kelley on the Toyota-Prius Yahoo group would say: Synthetic oil is
a BS marketing term that is meaningless.  What is important is how good it
is, not if it is labeled synthetic or not.  Real synthetics are group IV and
V base stocks.  Conventional is group II and faux synthetic is group III.

So which group is it that damages the low oil sensor?

Sorry I don't know.

I was at the honda shop about 3 years ago and a guy was buying an
eu2000i.  The sales guy told him to use synthetic -- I was there talking
to the tech guy about parts for my eu2000 and the tech guy jumped in
(with vigor) and told the salesman and the new owner to avoid synthetic
for the oil sensor issue.  He mentioned how they'd had to fix a few
themselves and how there was a honda internal tech memo about the issue
that had come out recently.

So I don't know any more than that.  Maybe it's no longer a problem with
newer gens or maybe they were wrong and that wasn't the the real problem
at all -- or maybe it is.  Just passing on what I heard about it from the
Honda guys.  

So I've avoided all synthetics in my honda for that reason.  Better safe
than sorry.
