Engine Oils

[elangoas]

why?
my friend said some cars come with fully synthetic oil from factory. Taken from team-bhp---The master of automotive engineering - Porsche - was the first car manufacturer to factory-fill its engines with synthetic oil before delivery.
So if synthetic oil hinders the run-in process why Porsche factory-fills their cars.
is it Fact or Fiction?


I used both the above oils in my Unicorn. First used CPR4T for 8000km with 50ml of Nulon engine oil treatment and very much satisfied with the results.
Filled Motul 10w40 and the engine has become rough compared to 8000km old CPR4T and not revving smoother. Motul is now 2100kms old and now there are leaks from starter motor area, clutch area. I'll switch back to CPR4T after this summer because of obvious reasons. so even if MOTUL is superior in its technology I found CPR4T better than MOTUL.
Also MOTUL is JASO MA, CPR4T is JASO MA2 so better clutch performance from the specs.

Many ZMA owners here said that Motul 300V FL seem to be better. hence inclined to try it.. Of course Castrol Power Racing 4T also seems to be good choice... Since i haven't used any of these, i need to depend on the actuall ownership experience.....

I own a 2005 ZMA and want to change my engine oil , the bike requires a 20W40 engine oil , can someone suggest what brand of oil to use for my ride.

Note mines is a 2005 ZMA.

Yes , I had exact same experience with the HH oil . Dunno how they are asking us to run it for 6000Kms .... anyone here actually done that ? works ?

I have used for about 4K kms, no issues, no problems faced, it could have lasted another 1K, but since HH oil is the cheapest, I changed it. Also 6000kms is not a publicity stunt as it is Idemitsu specs(idemitsu is leading supplier to Honda worldwide) and it's not HH property.

BTW, how much does the best modern 20w40 (mineral) last ? which is the best brand I can use for my achiever ? How much does Honda 20w40 last? it's cost?

it is not just my experience pls read from the first page of this thread so many users experienced the same problem while they are using wrong grade.
if i am wrong pls correct me.

i'm experienced these problems in my xtreme when i use 10w40 grade(rec-10w30)
engine run smooth but

depends on what 10W40,who are those people who were getting problems ?
I used a unicorn for 60,000 kms and experimented with oils ranging from 5W40 to 20W50,mineral,ss,fs..... and in that time worked on many of my frnds bikes as well...

the purpose of HH suggesting 10W30 for their engines is simple -
10W30 will not oppose much viscosity as compare to a W50,hence will revv a tiny bit quicker,and since the engine is revving easily,you might find a tiny improvement in milage...
But that is just half of the story, as HH and all other indian manufacturers say to keep the bike in 50~60kmph, the 10W30,will last for such short city runs,but in summer,even at such low speeds,the oil will loose it's thing due to the high temp's,and will let go resulting in excessive wear of the internals. Also if you go for about 50kms at ~70kmph with the 10W30 oil,the engine will become much hotter and rougher at the end of the journey. Also because of the oil letting go.

Motul recommends 5100 15W50 SS for the CBZ X-treme,Hunk..
and 300v Fs 15W50 for zma...

The best grade of oil i would suggest for all the 10W30 HH's would be Shell's 10W40 AX7 SS.Even motul 5100 15w50 will not harm the engine in any way,but the bike may feel sluggish in very cold weather till it is brought to temp.I say a FS for a 150 would be an overkill,rather get a SS and change every 3k kms.

And for those above 200cc,i recommend FS,full stop.
ZMA - ok,you can go for Shell's 10W40 FS or Power 1 10W40,but i still would suggest the moto4xt tech 10W50
Pulsar's - W50 is compulsary for us guys,220's must atleast use SS,but i recommend FS,motul 7100,300v or the moto4XT tech.

I did about 150 kms yesterday at 2~3pm in the scorching heat maintaining an average of about ~110 all the way,going wayy past 145kmph mannyy times,but even at the end of the journey,the bike pulled like hell>
going @ 110,innova taxi trying to crawl past,rip throttle,zooommm...
i Owe it all to the moto elf 4Xt tech and my NGK iridium's
no roughness or gear slip's at the end of the joiurney...total of about 175kms on the ORR

[RhythmRana99]

which FS engine oil recommended for R15??

[saurabhjd]

which FS engine oil recommended for R15??

what is the recommended grade fo r15??

[RhythmRana99]

20W40 or 20W50 as per owner manual.

Wherever we have an oil thread , we shall have great debate . Great inputs from everyone too . I am enriched by your experiences guys , thanks everyone .

thanks for the details,
which grade recommend you for me? just 20w40.
or can use 10w40. which is better for my extreme? in my area available oils are,castrol, shell etc.

Yes , 20w40 mineral , I am running that in my cbz-ex & new splendor too nicely . In really cold early winter mornings , cold starts were better with the HH 10w30 I had then ... but I only noticed that only when it was near 10C .Above that , 20w40 mineral has many things going for it . It's widely available cheaply (all companies have one 20w40 atleast), it's low range with least modifiers & additives , the base 20weight oil keeps the engine cooler & smoother than 10w30/10w40 etc .It is perfectly suited with my general weather range (Bengal-calcutta) . It doesn't get-lost/require top-ups as much as 10w30 .I love it !
I have no experience with synthetics .

Yes , some advanced car makers now have very special close tolerance manufacturing & now run-in their engines at factory , so they come prefilled with synthetic oil . Even the yamaha R15/R1 comes filled with synthetic yamalube , because it has the new japanese Diasil cylinder/piston technology , as the yamaha showroom guys told me . But AFAIK these honda/HH engines are pretty old designs and processes , so they are not comparable I think . Better run them in , by the old way on minerals .
Why do you need to use nulon or other additives with your oil ? I never needed that . It's not good for your clutch .

Note mines is a 2005 ZMA.

Gulf pride / ELf moto4 gold / Motul / Valvoline / Veedol ... even Servo/Hp Racer4 in a pinch , it's difficult to find a too bad 20w40 , they have been making it for ages now . If you ask any shop for oil they'll give you a 20w40 by default hahaha . Drain you old oil hot .

What about Castrol Power 1 4T , which is 15W40

[Pinaki]

I avoid castrols as a) they are a fair bit more expensive in the same types & grades as others b) too many fakes out there , so I have no real experience with it .I feel that these newer entrants to the Indian motor oil market are trying to keep their quality up and prices down , why not take advantage of the competition ..

Get Gulf Pride Plus 20W40 or Shell Advance AX5 20W40.

I have used for about 4K kms, no issues, no problems faced, it could have lasted another 1K, but since HH oil is the cheapest, I changed it.

You used HH oil for 4k?Even after 1000kms,my HH oil looks worst...

what is the difference between 10w40 and 20w40 grades?
with 20w40 grade engine revv freely? any problem in mileage performance etc..?

[Aneesh@4GHz]

what is the difference between 10w40 and 20w40 grades?

20W40 10 W30 is better than choosing a wider range like 10 W40 because the Esters added for the value stability is more and it deteriorates faster with heat.

Source: psr

with 20w40 grade engine revv freely? any problem in mileage performance etc..?

Revving will not be freely as before using 10W30 oil.But offers good engine protection.smooth engine and less heat and noise.mileage is still not confirmed and I don't think mileage will go down as it was recommended for older Karizma's....

Zmr

i'm planning to shift to fully synthetic motul 300v 15w40 in my ZMR after 10 k kms ! will drain it every 4 k kms !

will 15w40 do or 15w30 is enough ?

[dhiraj]

I have ZMR, which is around 8 month old, i want to change the engine oil, the recommended oil is 10W30, i want to switch over to fully synthetic one, so which oil i can use instead of stock oil?
