Engine Oils

Re: Engine Oils

Pros:
1. Vibes reduced.
2. Engine heat reduced.
3. Knocking in heavy traffic vanished.
4. Mileage unaffected.

Lately, after @psr sir's suggestion, I moved back to Rimula R3X. Used for approx 2.1 k kms.
Drained it recently. Found the oil turning blackish, but not pitch dark. But, this was he most dark drain so far.

Agreed with most things, but I find that the first time around, the oil was blackish and thick after a drain interval of about 1600kms. As posted before, I think the detergents in the oil had removed a lot of the gunk in the engine.
My Rimula R4 after about 2100-2200kms . Still going strong, gear shifts are smooth, engine is smooth (and cool - I disregard that since it's winter though). With the oil still in this condition, I believe even 2500kms or more should be doable on this.
On your oil drain, is the colour similar? Lighter? Darker?

Re: Engine Oils

What was the reason for going back to R3x? I just got 3 cans of R3x, manufactured in August. 250 per liter can.

Some changes have been incorporated which led to subsequent reduction in ZDDP levels in R4. It can be used, but I took PSR sir's suggestion without a second thought. Let me dig out his exact post on the same. Unable to find out as of now.

I used Mobil1 10440 FS prior to shifting to Rimula. It costed me 900 rupees to a liter then. It is an excellent oil, hence I never got a dark drain with the Rimula.
On draining at 1.8k on an average, the oil is slightly lighter to the one you posted above. The last drain was a tad darker though. Drained at 2100 kms.

Re: Engine Oils

I have Pulsar 150 DTS-i
Month and year of Mfg. is - February 2011
Color of body - C W Red

What is grade of recommended oil for this............??

Is it 20w40 or 20w50 ???
Or will it make any harm to my bike's engine if I use 20w50 grade semi-synthetic oil ??

I am willing to use Valvoline 4T Premium 20w50 Engine Oil, I have heard it is best suitable for the pulsar breed and it suits my budget also...........
Can't afford to pay more than 400 for the engine oil as I ride the Bike sensibly and don't Rip it, mostly I ride it between 40-60 with smooth accelerations..........

plzz help and suggest............
I have done 14000 Km's

The recommended grade is XW50. X can be replaced with an digit. valvoline premium is a good choice heard about it a lot. Not used it though

I guess the bike's manual should have the recommended grade mentioned. But, IIRC, pulsars have W50 grade recommeded. So, Valvoline $T can be used. Let actual owners/seniors also come up and guide you.
@B7ACKTHORN, Pulsars use W50 oil right?

Re: Engine Oils

After lots of positive response for hdeo oil. I bought rimula r4 5 liter for my palio gtx. 1.6 engine has zero lash hydraulic tappet and ran 75k kms. I will give my verdict after oil change

Re: Engine Oils

Maybe you should read the first post of the thread. Actually the numbers before and after W indicate viscosity of the oil. Simply put, the number before the W indicate the viscosity at low temperature and the one after W indicates the viscosity at high temperature.



You shouldn't use an oil that has a higher 'cold viscosity rating' or a lower 'hot viscosity rating' than recommended.

However, you can use oils with lower 'cold viscosity rating' and a higher 'hot viscosity rating' than recommended. But then again, there should be a limit for that also (especially hot temp.viscosity). A difference of 10 is perfectly fine. So 10W40 wont be a problem at all. In fact it will provide more engine protection.


I think you forgot to consider the fact that synthetic oils last more than mineral oils. So that calculation is actually incorrect. Please edit that portion of your post for the readers

Update on the synthetic oil leak issue for those who are interested: I came to know from a friend that the usage of some poor quality/old tech seals can also lead to oil leaks when you change from mineral to synthetic oil, after using the former for long periods. Very much possible, I would say.

Thanks a lot for this useful information bro!!.
I have few more questions:
1. How do we know when to replace the engine oil if the meter reading was not noted during last refilling of the engine oil. Hope you got my point.
2. Bajaj 10,000 DTSi oil claims that it can be used/run till 10000 kms and when I enquired about this to the SVC ppl they said at the most it can be used till 6000 Kms. But generally we do refill the oil @2-3K run. My question - is bajaj oil so good and robust that it can actually be used till the readings as claimed ?. Any thoughts ?

Re: Engine Oils

1 . If in doubt about the usage - I'd replace the oil at once . Early oil change doesn't hurt , late change does - simple .

2 . You are doing very well , best to replace this oil around 2000-2500 kms of use ( or six months if that comes earlier ) .

I am sure bro owner of p220 ..

Don't jump to conclusions , Pulsar 150 is not Pulsar 220 . Pulsar 150 of 2011 make most probably uses 20w40 . It was from the early 2012 that Bajaj started to recommend 20w50 dtsi oil for all pulsars , including the then current Pulsar 150s . So it would be best to take a quick glance at the owner's manual for the specific bike .

Recommended oil grade is mentioned in your bike's owner's manual , please read that first . It is important to be familiar with all the info thats in your owner's manual .

No harm shall come from using a 20w50 even if a 20w40 is recommended ( infact it may be a little more protected ) . Only the engine shall become a little slow to turn and you shall lose a bit fuel mileage . If you don't mind that ... it's just fine .

VP4T as we call it , is a very nice oil for pulsars .

1)You only need to have a rough idea of the kms covered after the last oil change. A small error wont do your bike any harm .
But since you asked, I will mention a few methods. One very common way is to check the colour of the oil though it's not 100% reliable. If it's deep brown or blackish in colour you probably need an oil change.
I'm not a great fan of continuous top-ups. If the oil level is fairly low, it's better to change it with a new filter than topping up. So low oil level is another indicator.
Some say you can actually feel the difference by smelling it or even by rubbing it in your hands.

2)I will start by saying this : engine oil and the science behind it is much much much more complex than what most people think here. Companies consider so many factors into consideration before they formulate the oil. It's a very complex product. So it's impossible to make comments on a particular product unless you have a deep understanding of the subject as well as the product.
It's a fact that people nowadays change oil more frequently than necessary. We no longer live in 20th century.
But motorcycle engine oils have the burden of lubricating too many parts. Heat and poor cooling mechanisms are huge issues. Even the best synthetic oils are unlikely to last 10k (or even 6k) km under real world conditions in a motorcycle. The fact is, if proven wrong, Bajaj can be sued for making false claims. Bajaj's claim is probably based on ideal operation under ideal conditions which is basically non-existent. But they say that the oil is made specifically for their bikes! I don't have anything to prove that they're wrong but I can say that it's highly unlikely that an oil would last that long under normal conditions.

I would still recommend a synthetic or a semi synthetic oil, not because it lasts longer (that is secondary) but because it offers better protection which a motorcycle deserves.

bro AFAIK bajaj has only two types of oils 20w40 (non dtsi) and 20w50 (dtsi). All dtsi's in bajaj use 20w50. Correct me if I am wrong

Re: Engine Oils

Of course you are right ( for the current models Pulsars ) .
But pulsar 150 models untill around 2011 came recommended with 20w40 oil by bajaj .
Also there is no equation like Dtsi engine = 20w50 oil , the Discover 125ST uses 20w40 , for example . And both the bajaj oils ( 20w40 & 20w50 ) are marked "Dtsi 10000" on the bottle - so there is no non-dtsi bajaj oil I guess .

So sir I was wrong. Confused dtsi with colours of can

Re: Engine Oils

Poured in a can of rimula r4 in my splendor. Could really the difference. The engine feels more ambient than before. I could Rev harder to get to 80 now. Just 5 kms review. Will post review after drain

Re: Engine Oils

@B7ACKTHORN, Pulsars use W50 oil right?

Though in part you've answered your query, most Pulsars less than 180 have w40 and upper than 180 have w50 grade just for a quick tip, in case the manual is missing. But as other members have rightly pointed, manual is your best bet. Or just Googling the right oil trade w.r.t the bike's name will get one the results.

Though Bajaj claims it a 10k and svc folks claim it a 6k, the practical usage for an average joe who commutes to office and tours and goes by his daily chores on a "Bajaj bike" is not more than 3k to 3.5k max. The only gripe is w40 grade is a very economical grade as now people know the advantages of using a HDEO in a motorcycle, the advantages are exponential compared to costlier siblings where you can get a HDEO grade like Delvac and Rimula very easily.

If you can get a DEO go for it, forget DTSI 10,000 and the likes.
