. Else it will have some japanese symbols like #$%$@ and we'll be wondering what those symbols mean.Anyway, I just want to share my experience on Engine oil I have been using so far in my Zma-R which has done almost 15k. Been using only HH oil 10w30 for the first 4k. Result is so and so. Changed to Castrol Activ 20w40 for approx 2k. Result not much different from HH oil except it felt slightly havier. Both tends to deteriorate past 2k. Changed to Castrol Power 1 Racing 10w40 (Fully synthetic) at approx 6k. Used first bottle mostly for cleaning so changed early after 1k. Better than than two previous oil. So got another CP1R, this I used it upto approx. 3k, not because it was getting bad but because I want to completly remove mineral deposits from earlier oil. Again got CP1R for third time. This time, I took it a little more than 4k. By the time I change, it was still running almost as smooth as new. Though I changed for two reasons. One: The colour was getting quiet dark after 4k. Besides I got a bottle of Motul 300V(fully synthetic) which I have been eager to try.
Hold it! Motul 300V for Zma-R. Factory recommended oil for Zma-R is 10w30.
The Motul 300v I got is 15w50
. Yeah, I know. Now let me explain why I did what I did. 1. 300v in 10W30/40 is not available in Mumbai.
2. Older version Karizma runs on 20w40
3. New Karizma-R(My bike) runs on 10W30, though engine is same . mmmmm.
Well, I have scoured the internet to learn as much as possible about engine oil. Though there is information out there more than I can possibly assimilate. I could not find a satisfactory answer to my particular need. So I thought, the best way to find the answer is to be a guinea-pig myself..well not exactly, I mean my bike. Test it myself and see how it performs as I have not come across anyone doing such a bizzare experiment.
Was I worried? Yeah, pretty much. Though I tried to make some sense out of it by looking into the whole thing. Now most review/test about engine oil are conducted on racing machines which not only costs 10/20/30 to 100 times my bike, but they are also built with far precision than my Zma-R which by international standard is some of the cheapest bikes on the planet and will not be subjected to such precision standard. Also I run in Mumbai heat and traffic which can rise to quiet untolerable level. To cut it short, I will get straight to the result so far.
First day on 300v. Weather was slightly cooler that day than today, Bike felt heavier like engine is taking a little more effort to turn. This was expected as the 300v is thicker. This means when engine is cool, RPM is hovering at about 60-100 RPM less when idle than it was when I was using w30 or w40. Things get back to normal when engine is properly warmed up.
My first ride to office on 300v felt slightly heavy though the heaviness disappeared after about 30 to 45 minutes ride. This could be due to oil thinning out to acceptable level as engine heat rises.
Fast forward to result after 400kms. Now even weather has become considerably hot. Heavy feeling has lessen considerably to the point of being hard to differentiate when using CP1R. Though in peak afternoon, 300v seems to handle better than CP1R which in turn handles much better than HH 10w30. In morning, CP1R handles better than 300v as engine is cool. The rest of the day in summer, 300v seems to be having the edge against CP1R.
Wanted to know how much stress 300v might be putting on my engine, so I decided to see the fuel consumption. You see, if engine is taking more effort to turn, then naturally consumption will increase and vice versa. 300v being thicker has shown that especially when engine is cold. Things are changing rapidly in favour of 300v as weather is getting hotter. So with CP1R, I get an average of 45-50 kmpl. With 300v, I have crossed 400 kms so far and still enough fuel to hit 45-50 kmpl mark. Another day or two will confirm this.
Other notes. Engine seems quiter due to thicker oil. effect like banging a can filled with thin water or thick oil. Gear shift better than CP1R. CP1R was also very good though it starts to loose its shine in the hottest condition. 10w30 mineral oil is quiet far behind the two synthetic oil.
Final analysis. No problem so far on 300v. I'll have to wait and see how far I can go, hopefully without problem. So far happy. If things holds well, decided to use 300v in summer where its showing promise and CP1R in monsoon and winter, as CP1R seems to have the edge when condition are cool especially for Zma-R. My review is not applicable to other motorcycles.
