Engine Oils

[saurabhjd]

Hi bro.What is single ester..
A GT250 Comet owner had recommended Motul 5100.

in case of motul, esters are the additives in the oil. it helps to keep the insides of your engine clean and also makes the oil run cooler. 300V has double ester and 5100 & 7100 have single ester. IMO, 7100 is good enough, it has almost every advantage of 300V way less expensive than 300V. 7100 is also fully synthetic & costs around Rs. 650-700. i m yet to test it on my p220. just make sure 7100 is available in the correct grade for ur bike

cheers

In my humble opinion - No .
20w40 is the perfect grade for your climate and bike ( same as mine too ) . What you can do is try out the better mineral oils in this grade like the gulf pride 20w40 / motul 3000 4T 20w40 , and change your oil a bit early .. say every 2000 kms or so .

Pinaki, Hey this is Boby Saxena. As informed earlier I am using Motul 3000 20w40 engine oil in HH Splendor NXG for the last 500 Km. My current ODO reading is 2500 KM. Today morning after a brief riding spell I measured my engine oil level and found it to be bit over the halfway mark (i.e. 75% approx). I am bit confused about topping up. As per my previous experience with my Maruti 800 and my grand old amby the engine oil is advised to be measured after cooling overnight, as the oil which spreads out in the engine while running (i.e.hot) settles down and the perfect guage could only be ascertained at that time. Is this the case for my bike also? and if top up is required is it normal after 500 Km riding with the new engine oil. Pls advise

Cooling over night is not required here,After riding your bike,Put your bike in middle stand and keep it for 20mins and check oil level.

i am having a karizma r and i am using 20 w 40 grade mineral oil. HH recommends 10 w 30 though. Well one of my friends said that he is using 10 w 40 grade on his karizma r well the question is what is the difference between 20 w 40 and 10 w 40 grade oil? and what are the merits of using 10 w 40 instead of 20 w 40 and which one is better for the bike? please help

^^^ As per my knowledge, if company recommended is 10w30, then you can go for 10w40 but never go for 20w40. 10w40 will flow better throughout the engine(compared to 20w40) especially when engine is cold.

I am afraid aneesh has already answered it correctly and I have nothing to add . like he says , 10-20 mins after a ride with bike on flat ground on main-stand . The difference in time with cars has got to do with volume only . The larger volume of the oil in cars , spread through the labyrinths of a fatter engine takes more time to drain back into the sump to give you a correct reading . I usually do a oil check in 200kms of a new oil fill , just to make sure I got it right ( totally unnecessary ) . Top up only if you find it below the min-mark on the dip-stick .With this oil the level didn't drop below the half-way mark in 2000+kms of use ever, so I don't care to even check now days . Ah , well .. one less thing to worry about in life . You seem to be distressed that your oil level isn't dipping like before ??!!

20w40 is thicker base oil and retains proper lubrication of the engine at much higher temperatures than 10w30 / 10w40 . 10w30/10w40 on the other hand is thinner base oil which circulates faster than 20w40 at startup cranking at lower temperatures . In my personal experience , if your ambient temperatures are between 10C to 50C .. use 20w40 ( i.e most of India ) . 5/10 base oils are for people who live below zero . i.e between -20C to 30C . I am being overly simplistic however . Read up on details on this forum and inter-net too .

We had discussed in detail in Karizma Ownership thread. Kindly flip back pages to understand the merits/demerits.

Amit- there is lot more to the properties of each grade of engine oil. There is no connection to factory recommendation and the liberty to use something else. In this case of Vishakh who is riding ZMA, would recommend 20w40 against HH recommending 10w30. Also see Pinaki detailed.

What you said is right 20w 40 oil takes time to heat up and reach all parts but for people who do more distance like me 20 w 40 has lots of advantages

Thanks a lot from the info you just poured in decided to stick with 20 w 40 grade as it serves my purpose

I have read all the posts about oils but i just needed to know the difference between using 10 w 40 and 20 w 40, in our karizma thread all discussions were connected to 10 w 30 oil

Thats true karizma used 20 w 40 till 2005 its then they shifted to 10w 30 so there will be faster rpm raise and fast heating up of oil . But its only good for short commutation like less than 10 kms . Using 20w 40 showed marked improvement, for me it was like the more i ride the smoother my bike becomes , less vibrations, lesser engine sounds and smoother ride

Welcome vishakh'jee & amit'jee .. glad to be of any use .

I would also like to dispel another common thing we often hear about oil circulation .. specially at morning cold start .
Every oil has a measured safe cranking temperature & safe pumping temperature . i.e the lowest temperature at which an engine can be safely cranked alive & the lowest temperature it can be adequately circulated by a vehicles oil pump . A vehicle in a good technical condition can be started at this temperature without any problems with this grade oil in the engine sump . It has been measured by independent oil companies under real conditions and verified by API .
For 20 wt oils ( 20w40 /20w50 ) the safe cranking temperature is measured to be below -10C and it pumps just ok at -20C . For 10 wt oils ( 10w30 / 10w40 ) the safe cranking temperature is -20C and it pumps at -30C . Now where in india would you be likely to exceed such cold ? In the plains , in cold mornings the engine is probably just around +10C . That is a very wide margin indeed ; of 20 degrees of cranking safely you have with a 20w40 oil . As for proper pumping & circulation that's a margin of 30 degrees . So at temperatures above 10C we should have no worries about inadequate oil flow / circulation etc weighing our minds at all . Even at 0C , a 20w40 would provide adequate flow and cold start safety .
However , if you do have to start-up at 0C on a daily basis , I would say definitely fill with 10w30 or 5w30 .. not for any real concerns ... but just to maintain that wide margin of safety & peace of mind . And this just for mineral oils , synthetics are said to flow perfectly well at least 10 degrees below these temperatures .
Oil flow,cold crankings & frozen coolant are things that few of my friends living deep in canada worries about a lot ... they use 0w20 synthetic oils too .. not me .. my teeth clatters at +20C .

+10 to pinaki sir.
Temperature chart under engine oil section in owners manual tells the same.
Btw, even in plains temperature can dip near 2~3`C.

[Pinaki]

...Temperature chart under engine oil section in owners manual tells the same.Btw, even in plains temperature can dip near 2~3`C.

Yes it can sometimes.. I've experienced 1C one day in Varanasi ... it was hideously cold and foggy ... my Rajdhani-express was standstill for 24 hours there bacause of the kohra .

[amitmalve]

^^ Ok... I got it(thanks to pinaki sir). Wonder why manufactures like hero-honda(now hero moto) & tvs are recommending 10w30 for their bikes.
