People are running 650f engines on 650r oil levels (no reported issues).I wouldn't want to go as far as that but -
So long as the oil level is ON the dipstick, you're good.
- seems a fair point, I accept that. ( but would prefer to keep it nearer the upper mark ! )

Not end of - a harsh comment that ignores the point being made originally that the oil level reads differently on each side of the dipstick, the instructions in the manual don't mention anything about that. I have never had any trouble checking engine oil level on any other vehicle so the comment about not being fit to operate a motorcycle on public roads is not justified and uncalled for.

I'm up for a discussion. The manual has a simple 6 step procedure for checking the level, and says just to ensure the level is between the marks.

Having it the same on both sides isn't a relevant point unless the difference is max to min (rather than a couple of mm).

If you have enough intelligence to safely ride a motorcycle, checking the oil should not present an intellectual challenge.

In my experience with people, the equation can be reversed and one can infer the fitness to ride based on their ability to perform simple, common sense tasks that are well documented.

My comment may be a little harsh, but IMO it is fair. I'm glad someone picked up on it.

'Checking oil today, level is different on each side of dipstick. Oil was literally on upper mark on one side of dipstick and on lower mark on other side'
If you have enough intelligence to safely ride a motorcycle, checking the oil should not present an intellectual challenge.- :arghh:

In my experience with people, the equation can be reversed and one can infer the fitness to ride based on their ability to perform simple, common sense tasks that are well documented.- o_O My point was the oil level is not clear if it shows at distinctly different levels on each side of the dipstick , and I am intelligent enough to ride a motorcycle and perform simple tasks that are well documented.

My comment may be a little harsh, but IMO it is fair. I'm glad someone picked up on it.- I picked up on it , why the attempt to insult people's intelligence on a forum like this where enthusiasts are trying to help one another ?

That might be ok when you have just changed the oil but not after you have ridden the bike a while and need to check the level to see if it needs topping up.


I get what you're saying. And your original question still hasn't been answered. All I can say is to check it to make sure you have SOME oil in it! I'd rather be a little short than too much!
That said, I imagine it doesn't make you feel any better not being able to get an accurate dipstick reading so I suggest to take the reading on the marked side of the dipstick and go from there.

Thanks , I think Drewster 123 might have answered it with the 'spinning the dipstick anti clockwise' suggestion before removing it. Will try that ( and see if I have enough intelligence to then read it ! )

Let me know if this method changes anything! If it does now THAT'S something that would boggle my mind!

D @Drewster123 I believe the oil check interval is much shorter than 2500k so the fact it went down was In that time was in you. Not meant to be harsh, just stating that I think the interval for checking is every ride, if it’s low you should add to make it right, it should e have a chance to get that low.

i did experience the weird readings in the dipstick as well, I think is the fact it goes into the case in relation to the oil level. As Drewster said a turn takes that away and it’s consistent in both sides. Great tip.

Why the hell Honda designed a new motor with a dipstick and not a sight glass I’ll never understand................

But no new engine should drop bellow the dip stick within the mileage honda staits between services! you should not haft to top it up. the services should be designed so this can not happen getting up to 8k on the same oil is daft.

Why not a service at 5k ??? Would make more sence I would not of lost any if that was the case as it was perfect at that miles.

I should of checked it more thoe yes . But if there was a chance oil level can drop bellow the dip stick in the middle of the mileage bewteen service's honda should put this into more detail.
When you use your bike most days / every day checking oil after every ride is daft

D @Drewster123 you're confusing two things which are not linked:

Service interval: this is dictated by the lifespan of components (oil, filter, air filter etc.) and expected wear rates (valve clearances etc.)
Maintenance check interval: checks for wear (premature or otherwise) and consumption of fluids etc.

Just because the oil is "in grade" (or still good) for 8000 miles does not make any bearing on whether the engine will use 500ml of oil in that period.

That's why check periods and service intervals are different.

For example:
Service interval is 8k (or 1 year) on oil - that's how long it will be good for. It's service life. However, Honda (if you ask them) will say that consumption of oil at a rate of 1 litre per 2000 miles is "totally fine, and will not be looked at under warranty". Do the maths - you'd empty the engine dry in 6k miles!

This is why you should check things regularly in between services.

Haven't tried it yet but I presume the idea is the oil is then at the same level on both sides of the dipstick . :) ps :oops: miweber already said that 'As Drewster said a turn takes that away and it’s consistent in both sides. Great tip. '

Read what Brammers @Brammers wrote: you are taking two separate actions, the service interval and inspection interval, and lumping them into one. Read your owners manual for the oil inspection interval, they are specific in how often you are to check your oil and you are to add if necessary.

"Loosing" or "using" 1/2 quart, or 1/2 liter, in 8,000km is not all that unusual nor is it alarming, especially of the bike runs at high rpms a lot.

According to my Honda dealer, "alarming" is when you start using a litre of oil in 1200 miles.

Some fireblades do when ragged hard (apparently).

Did you read what I wrote earlier?

The instruction manual states that oil should be changed every year, not just at every service interval.

The manual is quite clear about replacing all oil every year, irregardless of distance ridden.

My bad sorry yeah I understand what you both mean , I know honda does talk about oil consumption and I know where your both coming from with the manual.

What i feel in my opinion is honda should put this into abit more detail about the comsumption ,Such as allot of people pay for service plans becauce they might not trust themselfs to do mateinence so they pay so they can just get someone else to look after the machine.
Checking oil is a ovios one but most people just don't think they need to buy a spare bottle of oil for top ups . If a engine can go dry in 8000 miles honda should be telling people to get a spare bottle of oil and to make sure they check more often this could be very usefull bit of information for someone who dosent no what they are doing with a new bike .

Within 2 weeks of my CBR acquisition I opted to buy a quart of both my chosen brand of oil and Honda coolant specifically for topping off after periodic fluid checks. Didn't need the book to tell me that. Be prepared, my motto. Well, at least try to anticipate the inevitable.

Considering the 650r runs with 800ml less oil and the engines/gearbox appear to be broadly the same as the 650f ones - I doubt we need to obsess over oil level ;)

People are running 650f engines on 650r oil levels (no reported issues).

So long as the oil level is ON the dipstick, you're good.

J
2019 models have longer dipsticks to compensate for less oil level ! My dealer put half a litter less oil in my engine and he told me the exact same thing as you did.
