[Discussion] CB400 Engine Oil Change Interval

[HaiR1]

Ya... Pple like tat do exists

 

😀

Wahahahaha.... 15k km! Well done! :thumb:

 

That's enough lah, bro. Manual recommends 12k OCI, btw.

Please do vote on the poll at the top of the page. This will show others that Honda's 12,000km OCI is realistic.

 

the 12,000 km OCI is for ALL Super4, issit? How about the PB1/VerS/VerR?

I'm not sure as I only have the manuals for Spec 1 to Revo. In any case, the basic design of the CB400 engines have remained the same throughout the model range. If your engine oil capacity is about 3.2L, then the OCI should be the same.

 

If you don't have the manual for your bike and don't want to go too long between oil changes, going for 10,000km should be safe. Do note that this is always provided you use a good synthetic oil to start with. No need to use super expensive oil either. For older engines, I recommend you use a 15W50 oil.

....and there are people who use super expensive $33/litre oil and they dump the oil at 5-6000km!

 

 

haha ya seconded it. because i just did today. Well Bike was roughly 5000km+ mileage and I decided to dump it and changed it to Motul 300v today.

 

Waste money:dot: but can't help being curious which was better and also never use motul 300v before. But to my feel and honest opinion, Motul 300v 10w40 was to me "ok ok" compare to ap oil. God know what oil he use and mix things but I tried so called "popular" Motul 300v 10w40. Perhaps it would be better for track use as it is thinner and lighter. Different engine different feel but I can feel ap oil is thicker and able to last smoothness for at least 8,000km-9,000km. Just my 2cents worth.

 

Please feel free to input and share about EO feel and need for a change in EO interval.

[feelspeed]

similar riding style as me. i commute from bukit batok to simei monday to friday. im also spec 2, using ah pek oil. Current mileage on ahpek oil is 15k+ km. Still feeling good but i thought 15k is enough, maybe it's time to change. i will be changing probably end of this month.

 

bro pls update here what EO would you be changing or sticking back to ah pek's?

do u also do grounding from him?

[feelspeed]

Going by feel of engine is good. So what is the longest mileage you have done before you feel the need to change the oil? What oil was that? Also, what are the signs you look for that tell you "my engine needs an oil change"?

 

Well I just take out S4 spec2 only this year feb. Previously was 2b so I could not compare the longest mileage I had traveled on 2b for next EO change.

 

Usually by the feel of

-Engine roughness and sound of engine will be weird. I wish i know how to describe it haha.

-roughness in gear shifting

-bike will feel heavy and loss of power in moving off and maintaining throttle. Like become weak.

 

how about you bro ramsnake?

[buttbutt8]

My usage is low. If I change EO at every 12000km like some here have recommended, I will be changing EO once in 2 years!

[SKG_86]

[thechosenx]

Before my phantom on Amsoil i can use it til max max max of 7k. No oil burned or what so ever with amsoil.

 

Then used it on my CB400 till 18k with no problems or top up.

 

Then met ahpek. Tried his nano EO now 6k, i will try to go 20k or more

[exwhyzee]

I had my first and only oil change thus far last year june...approached ahpek for his nano EO...till now 16k engine still running fine...if ur amsoil can tahan 18k then try to push ahpek eo till 20k+++...tats wat most of those tat use his eo did...some even till 30k and beyond

Yah, surely no problem. I will also try to test at least a 25 to 28k

 

Of course depends on the feel, if it's really rough (which i doubt) then will change.

[Jonborah]

anyone riding Ver S here? what EO do you use?

[exwhyzee]

me im riding versionS...using ahpek nano EO

[randler]

whr do i get this ahpek EO?

[SimpleRider]

whr do i get this ahpek EO?

 

He (ah pek) is a veteran forumer in the PB1/VerR/VerS group. Kindly PM him for contacts.

 

 

Cheers!

[Baal]

I understand the manual recommend 12k oci. But normally I will just change around 5k. I'm using fully synthetic eo. I just feel safer this way. Cheers.

 

i also feel comfortable w 5k interval fully syn interval. manufacturer fig usually based in ideal conditions which almost never hapens in reality. Just like how they quote fuel eco...

[Hydher]

s4 is one hell of a machine

400cc but can beat many class 2 bikes.

 

A shared transmission bike will shear the oil really fast.

So take note if you are using synthetic oil which are group III based(which are most)

 

True synthetic Ester based oils are more stable.

 

Oils change intervals are like insurance and the manual sets a benchmark.

 

 

 

30k oci.. wow!

[foccacia]

where to get AMSOIL or Motul oil at cheap price? n how much? these 2 r 1 of the better 1 for S4 rite?

[lynx2606]

Is there any OCI for S4 that is based on time? Seem to be only based on distance. I travel only between 10-20 km a day so it can't be possible i change my engine oil once every 2 years right?

[drifter2013]

normal oil 5000-7000km

semi syn 10000-12000km

full syn 15000-17000km

Usually when u feel little bit hard to kick in 1st gear, its time to oil chg.

If new bike under warranty pls keep the oil chg timing schedule.

 

At least 6 months do the oil chg to prevent too much oil stain accumulated in engine block.
