If you were paying attention I said it was a tractor that I used in the
example, not a small vehicle. It is a legal requirement that commercial
vehicles have a Pre-Trip Inspection and Post-Trip Inspection performed
on them every day. Are you up to speed now, or do you require the
service of a tow truck?
It makes eminent sense though I'm fairly confident that such an
overnight loss of oil would be noticed in the garage by the pudle it
caused. Of course, it might be a different story if the vehicle was
What if the manufacturer designed the lines on the dipstick for
readings with the engine warm and shut off for a few minutes? Given
how the owner's manuals speak of checking the level at every fillup,
it makes sense that the dipstick lines would be so designed.
If that was the case, it would be impossible to get the correct level after
an oil change 'cos it goes in cold and straight to the bottom.
wha??? like it says in the owner's manual you mean???
this is an unbelievably retarded thread. just read the freakin' manual
- something that seems incredibly hard for some people to do. but
because i'm an anal pedant, i'll quote exactly what it says in mine:
"engine oil and filter
check the engine oil a couple of minutes after shutting the engine off,
with the car parked on level ground. remove the dipstick and wipe it
clean. re-insert it all the way down, then pull it out and read the
level. the level should be between the upper and lower marks."
nothing about "waiting for all the oil to run down" [ha ha freakin' ha]
or "thermal expansion" or even "keep it at the top mark".
so, next time you're in the gas station, after you've filled up, take
advantage of the fact that you're on level ground and have been standing
with the engine off for a couple of minutes, and the free wipes, to
check the freakin' oil. even a retard can do it.
I suggest you test that method out first. As I said in an earlier post,
after my CRV had been standing for over 15 minutes after only a short run of
the engine, the reading was midway between min and max. Checked cold the
next morning, before running, the level was a shade above max. I don't
care what the handbook says, that is my personal experience and, had I
topped up when getting the first reading, the vehicle would have been
overfilled. Try it yourself and see.
1. i have - there's no significant change.
2. honda know more than you. thus if it says "check the engine oil a
couple of minutes after shutting the engine off, with the car parked on
level ground", that /doesn't/ mean "second-guess with a head full of
read the owner's manual keith. it was written for people just like you.
I can only repeat (and rely) on personal experience built up over 50 years
of owning and servicing my own vehicles. I accept what you say but I don't
necessarily have to follow or agree with it. It works for me and that is
my main concern. The only other point that I would add is that the vehicle
had been serviced by Trident Honda in Ottershaw only a week or so previous
to my check and they would have put in the correct amount of oil. Whilst
the oil showed a level midway between min and max after stopping the engine
and standing for the aforementioned three to four minutes (actually it was
nearer fifteen), it showed smack on max the next morning. You may call it
superstitious bullshit but it would have resulted in overfilling had I
it's not "overfilling"!!!! dude, please try to understand, any reading
that is /not/ taken per the owners manual is not correct. there's a
massive difference in oil level between the correct and incorrect way to
read a detroit auto transmission level, but you wouldn't try to are that
they're both right would you?
this is why the manufacturer spends the time and money providing you
with a manual. if you didn't need it because all your 1950
superstitions were relevant, it wouldn't be necessary!
I am not arguing either way. Simply saying that I will use the method I
have always used. I see what you are saying about the manual but I still
come back to the fact that the oil only reaches the full mark when it has
stood for a long time. The undeniable fact is that I only got that reading
by leaving it. I think we will have to agree to disagree on this one
because my own experience of my Honda makes me regard the manual, however
expertly written and well meant, as questionable on this point. Curiously,
the manual for our other car, a Peugeot 406, advises checking the oil
before the car is started and warns that checking when the car has recently
been used will give inaccurate readings.
Then why have a Max marking when the level is supposed to go above that
later on? Surely that is a nearly Max mark, which makes no sense at all.
I haven't the foggiest idea what a Detroit vehicle is. I assume you are
referring to automatic transmission which is rare over here as we mainly use
manual gearboxes. You check the oil in those by crawling underneath the
vehicle and squirting oil into the filler hole (which is in the side of the
box) until it starts to run out. Simple but your back aches afterwards.
Which leaves the question of why, when it had only a few days before been
serviced by a reputable Honda agent, does it reach the Max mark only after
standing for a longer time. By that reckoning it should be above the mark
To be honest, I don't think, from what we have discussed, that it makes that
much difference. Next time I am at the agents I will quiz them on it.
I am not trying to be bloody minded. I am, more than anything, puzzled why
Honda should be different to every other car I have owned. I have also
seen the problems that can be caused by over filling, something to be
avoided like the plague.
it makes sense if you read the manual!!! the whole point of measuring
/anything/ is that you're able to do so in a way that is not only
accurate, but consistent. you don't use a rubber tape measure for this
reason. you get much more consistency measuring oil level at full
working temp, on level ground, a couple of minutes after shutdown - just
like it says in the honda book! all other readings, as you have proven,
are arbitrary and INCONSISTENT.
jeepers. logic. get some..
the point is, detroit transmissions typically require dipping with the
pump working. if you dip with the engine off, the level is /way/ above
the mark. you have to dip according to instructions to get it right!
have you ever considered the possibility that it's because they actually
know what they're doing???
