oil usage

anyone know how much oil a cbr1000f ought to use, over say 1000 miles
largly on the motorway ?
hvae just tipped 400ml in mine ( was off the bottom of the dip stick...
Doh!!)
Does it make a difference if it's ridden like a suicidal bat out of
hell ?

 

I'm not 100% sure, I took my eye off it cos there was no oil left in
the bottle at home !,. I hope I've not tipped too much in now.. that
could really ruin my day ! got some a lunch time, it's 8.50 a litre
from halfords, there must be cheaper places ?

It's accepted that Yamaha 1000 Exup engines will use about 750ml/1000
miles once they have over 40K miles on them. My Thunderace was getting
close to this figure when I sold it.

I figured that before long I'd be spending as much on oil as I was on
tyres.

 

Well if it's started using it you need to start checking regularly, with
the bike cold. IME engines vary in how long it takes for warm oil to
drain down into the sump.

If it was as low as you say then it's highly unlikely you've overfilled
it. Check again when it's cold, and make sure you're doing it with the
bike level.

Check it every day from then on, so you can find how long it needs
between top ups. My GS needed looking at every 3 days when I was using
it lots. OTOH my R1 never seemed to use a single drop, which is odd
because, as Lozzo said elsewhere, some Yam engines are known for their
thirst for oil.

I take it that you've had a look and determined it's not dropping the
oil via a leak, rather than burning it? Burning a bit is fine, dropping
it isn't so cool.

One would think so; what sort of oil are you buying though? You may have
bought some super-trick, ultra-synthetic, never-seen-an-oil-rig type,
which is overkill for an old POS. Plain normal 4 stroke bike oil will be
fine.

It's also generally more expensive to buy it in litres; by the sound of
things, investing in a 5l container of the stuff may be the way forward
for you. Keep the 1 litre container to stash in the bike for impromptu
top-ups, and fill that from the 5l, coz the bigger containers can be a
sod to pour accurately, and you don't want spilt oil all over the place.

thanks for the reply. I was checking it quite regularly, but I kind of
forgot for a while. At the last change I put motul in there, it was
expensive but the shop were I bought the oil had serviced the bike
from new and they said they'd used motul !

Like you say I'm going to have to track down an honest motor shop that
sells 5l tubs of vanilla bike oil at a reasonable price, hopefully
it'll stay a little thicker. BTW the Haynes BOL (and the user
manual) say to check it hot after about 10 mins. 'cos it expands a bit
maybe ?

I'll go and have another look, but I'm stuck at my desk at the moment!

Scottoil 500ml bottles are great for this because they give a long
flexible tube to screw on and that tube clips to the bottle when not in
use. 1 litre bottles are a bit too big to stash under a bike seat.

 

Slightly OT, but my old Golf GTI 2.0 did 1L of oil every 1000kms, which
according to the handbook was normal.

Fucking outrageous I reckon.

All of it. Then it scavenges it out of the sump, filters it, and uses it
all over again. I don't think 400ml is enough. The fatblade is a big old
thing, and would probably be happier with 3 or 4 litres to play with.

 

My GS750 did that too - although it *was* a complete rat I built from
the remains of my written off Katana 550, a 750 engine and frame from
the breakers and some bits from the shed. Fun though in an anti-social
kind of way.

 

Oh not *quite* as bad as my GS750 was before I rebuilt the top end - at
one point I had to check it 2 or more times a day (although I was
dispatching on it at the time).

 

Pretty good - picking up an ER-5 for Lisa tomorrow.

 

My '97 VR6 uses about the same but my '96 16v 1.8 GTI which I had from
new and ran in religiously used none at all.
