Not true.

I dont know what he meant by cleaning but i just got my regular servicing done from there. When i took delivery the bike had fresh Yamaha lube in the can.

I am sure he tried to make a fool out of me. I didnt get carried away by his expressions. It would have been worse if he told me that the engine has to be rebuilt for using a green coloured oil . Then i would agree that he made a fool out of me.

Eventually i took delivery of my bike after general servicing which included the oil change.

Much cheaper? I think it costs around Rs. 350 something, right? Can't recall exactly now. Also, most of the stock of Petronas is quite old. In fact the can I saw was over 4 years old, like I mentioned earlier. So the prices are old too. Motul 510 on the other hand must be pretty new stock. It also has a higher rating and its French.

Theoritically, if you let the old oil mix with the new one, the old one will never get completely exhausted. Practically, of course, that may or may not matter too much...

Beware of such people/places. If they take you for a ride this way, they very well do it in other ways too... and you may not be able to make out next time.

Hi guys,

I was intrigued by the posts condemning Castrol TT and was wondering why it is bad.

Let me make my posit clearer:

1. Is it lacking in lubricating capacity?
2. Does it not burn cleanly?
3. Does it not clean effectively (poor detergent quality)?
4. Does it cause deposits inside the engine?
5. Does it deposit too much gunk in the exhaust?

I am sorry if I sound argumentative, I am not being argumentative. Castrol Super TT was the best when it was launched over 20 years ago, I have lost touch with 2 strokes in the meanwhile.

I dose my fuel with approx. 1ml per litre every 5000 km or so and I have half a can of 500ml of Castrol Super TT lying in one of my cars for this purpose and am wondering if I should continue or get another brand.

Cheers,

[straight6]

@Spitfire - I have mixed old oil with new right from the start and have never had any problem so far. To drain the oil completely you have to take the pipe off and then drain it which means that there could be an air bubble which definitely isnt good for the engine.

I'll take my mech's word over any others. He's one of the best for 2 strokes here.

@Racoon - I get Petronas for 260/-(mrp 325). The new stock is going to be 330/-(mrp 457).

The answer would be yes on all counts. It does not burn that clean, will leave deposits in engine and exhaust, and smokes more. Smoothness also, not comparable to the better brands. I have no idea what it was like 20 years ago, but a few years ago, Super TT used to be just JASO FB and Jet X used to be FC. FB as you know has far lower detergency requirement. Now I believe it meets JASO FC and Jet X says it exceeds FC. Also, its priced higher than what its worth.

As I'v already mentioned, for a car, an FD rated oil (Motul 510) will be by far the safest bet as FD has much higher detergency requirement than FC.

Well another way to remove most of the old oil from the tank would be to siphon it off from the top. You just have to be careful not siphon it off completely as that could also introduce air into the system.

As for your statement about never having problems, its quite apparent that you wont see any instant problems!! The possible problem is that the life of the engine could be compromised to a variable extent, in the event that the mixing of different brands of oil with dissimilar chemistries causes less than optimal lubrication. And how on earth will a mechanic be able to test such things??

@Racoon - I get Petronas for 260/-(mrp 325). The new stock is going to be 330/-(mrp 457).

Thats a very significant discount you are getting over the MRP! Is that some kind of special discount, or do they offer it at that price to most others? I wish a newer stock were available here. Would sure have liked to try it out. :(

Any idea if the new (Rs. 457 MRP) stock is FD rated?

My mech has a ported RD. He mixes Motul 800 with Motomix in it and has been doing that for a long time. He is the finicky kinds who would never mess around with an RD engine since parts are not available these days.

I get the oil at dealer rate these days since I've bought quite a lot.

I think I'll have the 510 with me by Monday. Its expected to arrive here today or tomorrow. Will only be able to use it after a month though since I've just topped up with Petronas.

Forgot to share this earlier. Around 2 weeks back at around 3 am while going home from work on the highway I was trying out the top speed of the bike since it was dry. All of a sudden at full throttle the cable came off . Now the throttle was stuck at full rpm and I had no option but to ride that way till home. The only way I could slow down was with brakes and switching off the engine and then starting it back up with the clutch. I must have ridden like this for around 12-15 kms.

Next day when I went to a local mech to get the cable fixed, he pointed out that I'm low on 2T oil. When I checked through the window on the left, the oil had gone just below the window and could only be seen if I shook the bike. It was above the window when I left office the previous night. I had lost Petronas oil worth around 200-250 kms .

Thanks Raccoon - Motul 510, here I come!

Cheers and thanks again,

P.S. Anyone has an idea of where it is available in Hyderabad?

[straight6]

The 510 is here and I'll be picking it up on Monday as its raining a lot today. Mrp is 425/- but I'm getting it for 380/-.

Jeepers... thats bad! But did the cable break or did it get jammed?? From what you said, it seems it got jammed. Did you replace it?

It has just been imported for the 1st time. Hardly any chance of finding it anywhere. You'll have to contact Motul... have mentioned in a previous thread.

[straight6]

The cable came off. The mech fit the same cable again.

[Raccoon]

Then I really wonder how your throttle got stuch at full RPM...??? And thats what caused oil to get used up, right?

[straight6]

Here it is!

Slight correction. The Motul 510 carton has 20 bottles and the 800 has 12 bottles. Just found that out.

If I get impatient I may drain the Petronas out and top up with this .

[Raccoon]

Great! You got your bottle?! I still haven't got mine...

Why's it taking so long? Mine came from Pune!
