Engine Oils

[SriramEfunds]

So shall i mix both SS & FS or not???? both are of same grades 15w50 and same brands[motul] some of them said that it wont cause any problem in 220 dtsi thread and here some are telling that its not a gud idea to mix.

Never mix SS & FS oils even though they happen to have same number (15w50 etc). Their chemical properties are completely different and Motul FS is double ester where as the SS are technosynth. I might not give molecule level explanation however, to my year of understanding is that, Mineral, SS and FS oils are classified on their chemical properties present.

So You mean you want to mix Motul 300V 15w50 and Motul 5100 15w50. One of my friend has tried that and didn't face any issues, However I myself won't prefer doing the same.

Amit- Don't even think about doing on your bike. You can change the oil completely and run but don't mix them (only on the rocks!).

Thanks a lot for quick reply guys

Synth and semisynths are always a pleasure to deal with. Given the fine quality of Honda engines, I would suggest that you take the advise of Honda mechanics before shifting. They will judge your engine much better than we can. Since your bike has run decent distance, and if you are keen on shifting to synth's, then the best option would be to go for SS first 5K Kms and based on your feel you can upgrade to FS. FS/SS are good when it comes to city conditions.

I asked them they said don't use any other oil just stick with Honda Miniral

No, I don't have any technical explanation...Its entirely your call whether to use or not!!!

Hey Umesh, You can use Honda 10W30 full synthetic oil which is the stock oil for CBR.comes at a price of 500/ltr

Honda recommends 20W40 Oil

Try Motul Mineral as you need to go 2k this oil is fine ss or fs not required
just mineral will do

use the same company recommended grade

Which oil from motul are you referring to name? cost?

This is the correct explanation some people simply suggests what ever they know tough they dont know any reason behind that.

Any ways thankz for clearing my doubt.

The final decision always lies with you. If you are convinced, go for it..else stay clear.

HI,
I own Honda Unicorn 2009 clocked 13.5k Currently using Honda engine oil
i am pretty happy with it but after 1.3k kms engine becomes rough and gear shift becomes hard i want engine oil which can last for at least 2k kms
if i switch to SS or FS oil what are the pro or cons of doing so
my usage is 80% city mumbai traffic conditions

Umesh.

I had owned Unicorn '05 model and sold it recently. Coming to your point. I don't see any harm in using stock (Honda) oil for your bike. However, the life of the oil always depends on riding style and environment. For example:- If the riding always been in predominantly in higher RPMs, then the life comes down. Also, riding in city conditions would involve, frequent gear shifts and speed. So this also contribute to early wear of the engine oil.

You may shift to Semi-Synthetic oil (SS) and there are many in the offing from Shell, Motul, etc. I have used Fully Synthetic(FS) and Semi Synthetic in my bike. Both have performed exceptionally well during long rides. The oil change interval is slightly longer than mineral.

I would recommend you first try SS and see the difference. I'm sure you'll love the smoothness and reduction in engine vibes. Don't go by number of kms for the oil change. Oh yes! you'll need to regularly check the oil level and it's color. It should not turn dark.

Some of the recommendations which have already tried and tested on Unicorn:-

Motul 5100 (SS oil) - 5w40, 15w50
Motul 300v - 5w40, 15w50
Petronas (FS) 5w15
Shell FS - 5w40

The thinking on synth and minerals and mixing them is fast changing...read the contents of two Trust worthy manufacturers take on this......

ROTELLA NEWS: Will I Harm My Engine By Mixing Synthetic Oil and Mineral Oil?

Valvoline.com > FAQs > Motor Oil Car FAQs > Full-Synthetic Motor Oil

There is a lot of useful info in Valvoline's FAQ..

A synthetic oil contains more uniform smaller particles of oil ,and hence will leak past worn or ill fitted , or old oil seals, and gaskets.....With heat when parts of an engine expand , the resultant gap will allow Synthetic oil to flow through , causing oil leak and oil consumption in engine.
A mineral oil contains Base stock with Wax which helps to seal and not allow this to happen...

First of all Thank you for your valuable suggestion

I usually gears shift between 3-4.5k RMP
I will try using Motul 5100 15w50 SS
now i have honda stock oil and i am going to change it within a week.

I will post impressions as soon i change
any idea's about pricing?
honda oil used to cost 200 bucks

[Dogg]

Well, on the 220:

1) Any significant difference between 5100 and 7100/300v?

2) Any significant difference between 7100 and 300v?

the 5100 is a good oil but does not even last for 2k kms. i have used the 5100 for 6k kms and each time the mech said that the oil was gone,even after just 1.8k kms...

as for the 300v, i fell the price is too much. i felt the moto4xt tech FS 10W50 much better than the 300v and the price is arnd 650/-,that oil if topped up when required can be pushed to 3.5~4k kms. as for the 7100,it is meant for the thumpers (as illustrated on the bottle),i guess it can also be used for any othe rbike,but i returned that bottle and went back to moto 4xt tech.

guys i had put motul 3000 4t 15w30 in my rtr 160, is it good for the bike?

[MSN1]

Thanks a lot for quick reply guys


I asked them they said don't use any other oil just stick with Honda Miniral

Honda recommends 20W40 Oil

Which oil from motul are you referring to name? cost?

Try MOTUL 3000 4T Plus 20W40 it wont cost you more than 220 rupees for 1 ltr, it ill come good for atleast 2000 kms

Try a thicker oil like 20 w 40 or 50...RTR is a rev friendly bike, Air cooled,....and also generates heat....On long drives with sustained higher RPM there are many reported cases of engine oil being consumed leading to engine seizure.

Dont jump! Complete atleast 6000km on the odo before you can think of SS or FS oils.

FYI.. It is recommended that Mineral oils be used for 5-6k kms so that engine is set properly as there are many moving parts which mineral oils would actually act cooler than SS and FS.
