@chaudh2s, the carb is an original MGP one. It was made in August 2012 and I guess was stored in the companies storehouse as the part was ordered only a week before the installation. The SA had told it would be tough to get one but eventually he was able to source it. I remember he had mentioned that Sagar Automobiles had ordered 4 carburetors. It cost me Rs 7000. The carb which is sold as a MGP piece is made by a distributor by the name UCAL. The older carb and the new one both of them are made by UCAL. I will try to get hold of the box in which I have kept the old carb in. It has the part no. for the carb.

I managed to find the part no of the carb. It is 13200M72FZ1. The carb which is distributed by UCAL has the carb on their website. Link- http://www.ucalfuel.com/4-wheeler_Carburettor.asp

For my next service, I plan to get the oil changed in front of me. Car has 82000 KM on the odo.

What is the general recommendation for engine oil brand/ product for Zen carb?
I am not willing to go for the 'premium' (expensive oils). I don't need any special performance.


Running is around 400KM per month in the city.
For my other car, Cedia, I need to go for 10W40.

[swamyzen]

@S_U_N go for Castrol Magnatec SAE 10W-40. This is the only oil I have been using for my carb zen and I guess it is responsible for keeping the engine smooth even after 1.63 lakh km's. Yes, it is synthetic but I would recommend it if you want to keep the engine smooth and get a bit more of power. On one instance I had used the MGP Shell oil but felt the engine was not silky smooth as it would be with the Magnatec. If you don't want to go for Magnatec then go ahead with MGP Shell oil.

Thanks.

Since my engine is now run at 82000 KM, I am not keen on changing over to synthetic at this stage. So, I will stick with mineral only.

Castrol Magnatec is not a synthetic oil, This is a semi synthetic oil.
SUN - this oil is good for most older cars. Last time I picked up this oil it was Rs -1450 - for a 3.5L can.

p.s
Castrol Magnatec also comes in 5W 30 which can be used on a cedia (4L Can).

[swamyzen]

Sorry, 10W-40 is semi synthetic. On the box it was given synthetic technology so assumed it is fully synthetic. Checked on Castol's website there it was explained that 10W-40 is semi synthetic. Sorry again.

At slightly cheaper side, there is Shell Helix HX5

I checked out the cans at the Shell bunk this morning. Somehow the cans were all dirty, though the stock was 4-5 months old.

How good is 15W-40 grade?

Very Average oil, works for a normal car.
This is for your Zen or Cedia?
If its for this Zen this oil will do. Make sure you stick to 6 months / 5000KM change interval
Old stock doesn't really matter.
Locally I can get this for 1000-1050 4L can. (check outside the shell bunks) You can get them for less..

15W-40 is viscosity or weight, grade is different. In case of the above-mentioned oil it is API SL (same as the venerated Castrol GTX). Strangely, the cheaper HX3 20W-50 is now also rated SL. You might as well buy that. I use it in both my 800 and Zen, and a trusted mechanic swears by it's VFM nature. A 3.5l can costed me Rs. 750 in Delhi. The minimum requirement is SF for the Zen, which is the grade (or aukaat) of the Maruti Genuine Oil which costs ~900 bucks for 3l.

Also, stay clear of anything thinner than 40 weight (the 40 in 15W-40)- 5W-30 is bad news for the Zen even if its is fully synthetic. Considering the engine has done over 80000 kms, thicker oil (20W-50) will make better sense.

So, Shell HX3 20W-50 is fine for Zen?

Is right, 40W should be the minimum for an older engine like the zen.

20W50 will also work but you might notice a slightly lower fuel economy and your engine may feel under powered.
If your running is very less then this shouldn't be a problem.

[saket77]

I normally use 5W-30 Magnatec since beginning. The engine has done just 30K kms. Considering the engine is not run much, I presume I should be okay.(?) Any thoughts over it?

Well, in that case, I would not be willing to put it in.

The current state of tune is already towards fuel efficiency. I don't want the oil to reduce the pickup.

So, I will skip the 20W50 Shell Helix HX3

My mechanic is using oil from a Korean company called Zic. He swears by it and has put it in cars from Audi's to Maruti's.

However I discovered it is synthetic, which I do not want to go for.


I will search for a good price for HX5 15W40

Continue using this grade not a problem. After you cross 1/1.2 Lakh Kilometers based on the condition of your engine you might want to shift to a 40 grade oil.

Never heard of this oil company called zic, I wouldn't want to use an oil like this in my car. (google shows it to be some company based in Pakistan)

Search for the hx5 or you can ry Petronas Vision 15W40. Saw a 4L can Rs800-850
