oil

[tubsy]

hi does anyone use any oil used about half a pint in 2500 does this sound normal I know I had a cbr600rr and got told it is normal to use oil on modern engines but had cbf1000 and used none inbetween service got 2015 model

Doesn't sound particularly bad.

But, I've never had to top the oil up even going the full 8000 miles between services.

Be interesting to here how much others use.

I've never heard of a VFR engine using much oil at all. In the 58,000 miles I had my pre-VTEC 800 it never needed topping up between engine changes.

How did you run the engine in?  Did you make the first oil change after 800 miles or so?

ex demo bike so did not have it from new it seems that when riding it hard is when it uses it

Mine's an ex-demo bike too and burns no oil at all.
These days the recommended running in procedure is limited to "avoid full throttle starts" or words to that effect, but I still think an engine will give better longevity if run in properly.  Perhaps your dealer thought differently..

If you are using synthetic oil, you might find an improvement by switching to semi-synth or mineral oil.  Semi-synth won't make any difference, but I would change the oil every 4000 on the dot if using mineral oil.

Hello,

I was having the same "shock" when I casually checked the oil on my bike for the first time. My previous bike was a CBF600 PC43 which used absolute zero oil in between the regular checks and never required any oil to be refilled any time.

I bought my CR in February 2015 ( new model ) and went easy on it for the first 2000 km but after that I progressed to ride it properly. I am not driving like a maniac but its just too much fun not to twist the throttle.
When I realized that the engine likes some extra oil I went to my dealer and kept a log of my oil usage.
Here is what it looks like, ( sorry for the odd numbers but i had to convert everything from metric - oh and just for reference the oil usage from "tubsy" is around 0.2pt per 1000mls )

first check oil and filter change at
1096km     oil full        10W30
681mls

3683km    300 ml    10W40   delta   0,116 / 1000km
2289mls   0.634pt                           0.394pt / 1000mls

5266km     400 ml    10W40   delta 0,253 / 1000km
3272mls    0.845pt                          0.845pt / 1000mls

note: Here I was testing it. I went on the autobahn and let it run for about 250km at definitely more than 7k rpm forcing the VTEC to do something for its money.

After my test ride and topping up again I went on a tour to the Balkans. I say that because for the following almost 5000mls my style of riding was very "touristy". Very easy on the throttle relatively slow and steady, mostly 6th gear and 50-70 mph.
I had to top up the oil a couple of times and here's the result:

13068km    825 ml   10W40   delta   0.106/ 1000km
8120mls     1.74pt                            0.359pt/1000mls

The 12000km check interval was done at 13068km or 8120mls in August. The oil and filter were changed.

As of today the clock shows 15300 km ( 9506mls ) - the engine has not used a single drop of oil. I do check it now every time I ride and even with the lower temperatures and a "higher rpm style of riding" I did not see any changes in the gauge glass.
I have found two more people with the exact same oil problem in the German forum who told me that their CRs too stopped using oil after the second oil and filter change at around 12000 km.

ride safe everybody !

Mine is using oil, nearly a full litre in about 4000 miles. It's a 2015 ex-demo. I do a lot of city commuting so it does get hot a lot.
I tend not to get into vtec range when I'm commuting either.
Hopefully this will stop happening like the guys above as I didn't buy a Honda to have to keep checking the oil!

Only done 1700 on mine, but not used any oil up at all.
