If I remember correctly, 20W50 oil was recommended for bigger engine Bajaj bikes i.e. 180cc and above. This was until a year back, which was the last time I visited a Bajaj A.S.S. All others had 20W40 as the recommended specification. Even the company recommended Bajaj DTSi oil came in 20W40 and 20W50 guises, to cater to the different bike ranges. Please do check once again and ensure that the service centre is not fleecing you with a more expensive but wrong oil.

Verify the circular once.

Using a 50 grade oil on a 40 rated engine will not cause any harm. The fuel economy may reduce by 1 or 2 kmpl. That's all. However using a 30 grade oil on a 40 rated engine will definitely cause excess wear and tear

Over here, they use the 20 W50 in all the engines, irrespective of their cubic capacities. However I personally do not prefer the Bajaj oil, as it tends to give up sooner than say, a Valvoline. The bike feels rough and less eager to rev.

From among Castrol Activ 4T and Valvoline, I find the latter to be better.

[ksameer1234]

I did an oil change for my Discover 135 and found that Valvoline has Champ 4T 20W40 which is API SN rated while every other oil was either SL or SM at best. Given that other options were overpriced Castrol and some multigrade Bosch, I went ahead with Valvoline. Past experience with Valvoline has been great and it is a perfect match.

However, I haven't been able to find Petronas 20W40 (don't remember the brand) which gave best performance and mileage. The downside was that oil would hold only for initial 5 kms of ride and then the shifts would become rough. I guess the oil was thinner and fearing further damage, I switched back to Valvoline.

I was planning on upgrading to the 15w50 Semi synthetic oil for my Royal Enfield UCE 350 (from 15w50 Motul Mineral). I went to the shop i regularly visit and Semi Synth 15w50 Motul was out of Stock. Another dealer suggested that I buy the Eni Agip Semi Synth 15w50. I would have tried that out if it weren't for the price at which Eni is sold. The 2.5 Liter bottle of Semi Synth 15w50 is sold for Rs.750. That's less than the Motul Mineral oil (which is sold for Rs. 850). Does anyone have any experience with Eni??

My Bajaj Discover 125T has 20W50 as recommended oil. (I suppose Pulsar too has same reco). Bajaj other 125 (125, 125M) use 20W40. I don't see 20W50 in retail in this part of town (incl. Shell Pumps & couple of Castrol dealerships). Any quite few guys have their pulsars running with Shell 20W40. Service station fills Bajaj co branded HP 20W50 (Honestly, don't know if they actually change oil. I don't want to trust them regardless).

Now question:
- Is it necessary that 125T needs 20W50? (Or it just a Bajaj gimmick?)
- Where can I get fresh 20W50?

ENI or for that matter wurth synthetic/semi synthetic are absolutely rubbing oils. We see a lot of complains at the local mechanics with them. Initially it was a great deal for the retailers and mechanics as their buying price is nearly half of Motul and Mobil. And they were very happy with the profits. But then started the engine failures and seizures which are unheard of these days. Even regular HP, IOCL, BPCL mineral oils don't lead to seizures.

One has to understand that in a market where top volume leaders are fighting to cut even Rs.5 off their prices, how these low volume guys are able to give such low rates and good margins.
For instance wurth synthetic 5w40 5L has a MRP of 5.5k I think but has an unimaginable retailer price of 2.2K. That's the kind of margins it offers.

Please stick to Mobil or Motul for your oil needs. Motul has 5100 15w50 for the RE in semi synthetic in 1L packs only and you can use that. A lot of bulleteers here use it.

Among the Bajaj HP, Shell AX5, Shell AX7, Mobil 1, Motul 7100T, Motul 300V I used for Pulsar 135LS, I found Motul to be slightly better than Shell. You can stick with Motul 7100T if you dont mind paying 700+ Rs. Mind you, the drain intervals are significantly longer for Full Synthetic Oils.

I really wish if I had read this before buying the ENI. I should make my visits here more often. To be very honest, I thought the low rates were a marketing strategy to make a way into the market and create a reputation for the same. After all, ENI Agip is a very popular firm abroad.

I drained the Agip after 800km and went back to Motul Semi Synth. Ahh, the feeling of Zen!!

Is the ENI engine oil that you are referring to the same as the Agip engine oils in the Indian market? I have only heard positive things on Agip engine oils especially from R15 owners who used to take it to the track (back in the pre-KTM days that is). I dont have any experience with Agip though, I used to stick with Castrol and Motul options.

Dad's Bajaj CT100 engine is getting a new cylinder kit.

Which engine oil(mineral/synthetic/semi) to use for initial running in period?

Yes. That's what I felt too. And, this is my experience :

Vehicle - Gladiator Dlx (125 cc) 2006.

For the first 25,000+ kms servicing was done only at Yamaha Service Outlets and they used Yamaha's oil.

Subsequent 10,000+ kms used Castrol Activ. No perceptible difference.

Next 10,000+ kms used Shell AX7 (15w50). Initially the bike would be very smooth, which would then become harder within a month.

Switched to Motul 5100 (15w50) (nearing 50,000 kms now). Not much of a difference between Shell and Motul, but Motul seemed slightly better. However, crossing 2,000 kms the bike would cry out for oil change.

This time wanted to try Valvoline (based on reviews here and other threads).

Shop keeper suggested Gulf Pride 4T. He was going blah, blah, blah on the Dhoni commercial. Personally, I am the last person to be convinced by celebrity endorsement.

But remembered my KB100; in those days (30 years ago) Gulf 2T (green coloured) used to be more appealing (others were yellow / orange / golden brown etc.)

So said what the heck, let me try it out (even though stepping down back to 20w40). Plus one litre pack was available (Motul & Shell cans used to be of 900 ml, as 1l cans were not readily available, and it was always a point of concern, as the dip stick level would be towards the lower end....)

These are the virtues extolled by Gulf -

1. Life boosting 'oxy-bitors' added

2. Drain interval of 10,000 kms

3. JASO MA2 / API SM

4. Cost Rs. 300/-

A week since oil was changed - bike feels pretty smooth (as good as Motul).....

Since the engine oil is going to be replaced at 1000 kms and our engines wont be redlining at any costs, I would recommend using mineral. I am using Castrol 20W40 for breaking in my recently built Pulsar engine post which I will switching to Motul.

[devarshi84]

Using Savsol 5w30 synth for winter cold starts on my two suzuki 125's. They have a collabration with Idemitsu but not sure if this particular oil has any inputs.

any questions are welcome.

[saket77]

Just got Motul 10W-30 3100 Gold for my stunner. It's a mineral oil but feeling is good. Will post the impressions once I clock a few kilometres. Paid Rs 350 for a 900ml pack. Printed price is Rs. 373/-.

Regards.
