Engine Oils

Re: Engine Oils

@ vivekgautams - I personally feel, when an FS starts to reduce in volume, it has lost its viscosity. Why dont FS starts to vanish from day one? And they starts becoming low in volume after 2000-3000 km. I would top up an FS just once or 4000 km in a bike. If no top up is required, you can go till 5000 - 6000 km mark.

But anyone of you know someone who did not top up an FS oil till 5000 km?

I did not top-up the FS oil & after 7500km+ the oil was due for change & during the change,I found the oil that was drained measured to be just 500ml...

Re: Engine Oils

@psr,Mushtariq and Shoeb attention guys ....
After 1000 kms usage I have opened dip stick to check oil level and quality. Oil was as good as new, no colour change at all and no drop in level.
Fine, but I am not convinced about this fresh colour. Earlier oil(Veedol super swift 10W40) will change colour within 500 kms.

Out of Curiosity and to clear my doubt, I took the bike to my regular mechanic and ask him to open clutch side case. While draining the oil, mechanic was also asking me the oil looking as good as new, why you are asking to drain?

He took out the oil strainer first and to my surprise the strainer was 70% covered with black precipitate though nothing at centrifugal filter.
I should have took photo but unfortunately I forgot to carry my phone.

In my previous oil filter cleanings(every 10K kms) I either found nothing or very very little amount of dust. ..

You have made a very timely and intelligent observation , I feel . A motorcycle engine oil not changing colour to quite darker in 1000 kms of use is not good . It means either the oil is not cleaning well or it is not able to keep all the collected dirt in suspension ( without depositing it inside the engine ) . It may or may not be a effect of HDEO oils in particular , perhaps just in your bike just this once some random dirt got disloged and strained . Thing is that right now , we don't know for sure . Which is why it cannot be ruled out and you gotta keep your eyes wide open - which you did very well too . A 70% blocked strainer does no good for oil circulation .
few things that they definitely did not consider while making HDEO oils is -

i) that it would immerse a clutch case and withstand constant shear inside a gear box .

ii) that it would work through strainers and centrifugal filters , since all diesel engines have inline disposable-media (paper) filters .
( This gives rise to one possibility in my mind - Oils working through inline paper filters does not need to keep the collected dirt in suspension all the while . They can discard it in the filter . Hence they may be lacking in the additives that is necessary to keep engine effluents in suspension for it's working life ) .

iii) engine effluents arising out of high-compression diesel combustion are not the same as that arising of low-comprssion petrol engines . Does HDEOs have sufficient suphuric acid-neutralizer to last the usage period of the oil in motorcycle engines ?

Anyway - you should have kept photographs tsk tsk tsk

... Regarding the splendor's drain bolt location under the Mesh, what a simple and functional location. It will clear most of the debris during drain and no wonder splendor's engine lasts very long.

Yes , it is the singular credit of this one engine that Honda is a well regarded name worldwide today . Amazingly it was designed by soichiro honda in the 1950s and first used in the Honda CUB and SUPERCUB . Declared the best motorcycle ever made, by the Discovery channel .

Re: Engine Oils

My Oil history: After I got my brother's Unicorn
Veedol Super Swift(3000kms), CPR14T(8000kms), MOTUL 300V 10w40(3000kms), 15w50(2500kms), Shell Mineral(200kms), ELF(5000kms), Gulf20w40 (800kms), Gulf 10w30(600kms), SHELL(6000kms), SHELL(5500kms), Honda Oil (400kms), ELF(6000kms), Valvoline Premium 4T(2400kms), DELVAC 1300(2100kms), CPR14T(700kms and going on)
Never needed any topup. Oil Level never dropped to the lower mark on the dip stick.

The FZ dipstick has 200 ml of oil from max to min position.

If you didnt top up, you didnt lose oil is incorrect. You dont top up to see the mark above minimum, but you should do it to maintain maximum.

Everybody looses oil whether it is synthetic or mineral. As a matter of fact I always get 800+ml after draining. I never noticed any FS oil going below the minimum mark in my Unicorn. And as long as the level is in between the 2 markings it is safe and I don't (not should) need to maintain the max level all the times. If one needs to maintain the oil level at maximum only what would be the purpose of Min & Max level markings??

Re: Engine Oils

@ Vivekgautams...Please do not extend engine oil change in motorcycles beyond 3.5 K for FS....The engine oil in a Air cooled engine goes through great strain ,and it's life is always miserable inside the engine....Delaying the oil change leads to Sludge and Varnish formation, both of which is not good for the engine...
Even in cars it is better to change the engine oil at 5~8 K kms depending on period of use, and nature of use....
It is better to use Mineral oil , and change it at 2 K Kms in Bikes than using FS for longer time and Kms.....Using fresh engine oil every 2~3 K kms helps in the proper maintenance of the engine..
[MENTION=57256]NIGHTMARE[/MENTION]....I am at 1,100 Kms on Shell Rimula R3X and will change oil once I do 1,500 kms...The oil looks good so far , no sludge, and level is same as when I filled it fresh.
The Gear shifts are smooth and easy, and finding Neutral is easy now....What exactly did you mean by 'Bike throttling at 80 Kmph" ? the gear shifts will make clicking noise and shift easily and positively with R3X....
Mr Babu76,......the Diesel oils contain dispersants and detergents to keep the diesel engine clean inspite of heavy combustion residues . This also means it does clean the inside of engine (detergents), and in case of Petrol engine, previous deposits inside will be now cleaned up....I can find out only when I drain my bike oil to know....

The engine oil level should be as close to maximum level.

The use of 'should' word is clarified by this flash video

http://www.morbela.ee/mobil-maardeained/flash/oil_check_guide.swf

Though there is no hard and fast rule to maintain Maximum level all the time. But, difference between max and min is around 20% of the fill volume. If you are at the lowest level you are driving/riding with around 20% less oil than you could have.

When I used to fill TVS's Tru4 SS, the bike would do a max of 1.2k km..I guess I expected a lot from FS & pushed it quite hard..Now on wards I'l change it by 4k km..
Cars have a oil change timetable for every 10k km if it is SS OR 40k km on FS, this is given by the manufacturer itself...

The sump size of car is much greater than that of the bike. Also, the car oil does only the job of lubricating the engine. Whereas, bike oil has to protect ECG (Engine, clutch, gear). And the sump size is relatively small.

Also, properties of bike oil and car oil differ a lot.

Cheerz!!

You need to understand, there isn't one BEST oil all on. Would you trust diesel engine oil which would give you good results

SH is a mechanical genius, and I don't know why you posted this all of a sudden but did you Charles Boorman using cooking oil in the engine and dropping it from a 5 storey building and still the bike starting, and indicator working.

Priceless. No wonder it's the largest selling two wheeler of all time. :thumbup:

My thought also as quoted. I was also frustrated for not keeping phone with me to click the pictures.

I saw that episode in discovery documentary. I was amazed to see Cub above Ducati and Y2K..Bit confused too..

Why confusion? What's practical and simple in the end almost always gets the upper edge. Try doing all the things the cub went through all the 10 bikes, most of them would stand no chance.

Yeah I have seen that episode too.....remember y2k burning up a car's bumper too :P
He used oil used for making pizza....whoa cool.....and how bad did he load that Cub with sooo much of items!!
