Are multigrade engine oils suitable for older swifts? Do they harm the engine in the long run? Some people tell me that diesel cars have become rough after 1st engine oil change. I feel that multigrade engine oils must be avoided in modern diesel engines. The best engine oil available for Swift Diesels is Castrol Magnatec 15w40. It makes the car very smooth after oil change but after 5000 kms the engine sound increases slightly. But multigrade engine oils are a travesty.

Sir,
Please help me.
I have just serviced the ritz diesel. They have put 80w90 gear oil in the gear box. During cold starts there is a rattling sound that disappears as soon as the clutch is depressed. I am very worried about the car. I have stopped using the vehicle. The sound vanishes after the engine warms up. There is a whirring sound followed by a rattling in the morning. The rattling and whirring sounds disappear after pressing the clutch pedal. Is it due to the thicker gear oil? Or should I change the Engine oil? The sound appears to be coming from the left side of the car. Is it serious? I checked with MASS. They said that it is normal because the gear oil is thicker in the morning and takes some time to flow freely. But still I am not convinced.

Definitely not normal, this sounds more like clutch release bearing sound. Gear oil would not cause any such news, esp in neutral and while stationary. Suggest you get it checked with another workshop.

Circlip is a clip that holds the gears together on the shaft.

Please have your car checked at the earliest.

It could also be just a stone lodged between the calipers, try coasting a few meters with the clutch pressed and if there is no variation in the sound then it's the brakes.

Hope this helps
Hi All,

Update on the issue reported above.

There is a bush near the inter-cooler which was broken and it was replaced . The noise has subsided but I think there is a faint noise still present.

Anshu Rao,

Can you please PM me your swift's registration number so that the local mass can look up the work done on your car thru DMS ?

Default Re: Swift Diesel - Engine sound

The knocking is definitely not due to lube oil and in my opinion you need to clean the injectors and see. the knock is only a result of tuning for a better fuel efficiency. There are good engine mounts that can help in reducing the audible component of knocking.

Without hearing the actual sound its always very difficult to tell. Check if that oil is per the recommendations in your owners manaul. If not, get the. To replace immediately. But assuming they put the correct oil in, here a thought on what could be happening. it could be purely due to the oil being cold. Gearboxes tend to be more noisy whilst the oil is still cold. You get a sort of slushy, slightly squeaky sound. It happened to me years ago on one of my cars and when I investigated I found that some of the rubbers isolating the gearbox from the cabin had perished. Normally they provide a degree of sound insulation. As they had torn, the sound made it into the cabin. Replaced the rubbers and the noise was gone. Well, it was still there, but you couldn't hear it anymore.

I think you do need to get it checked out by a competent mechanic.

But Sir, the sound is very odd. There is a slight increase in rattling sound on releasing the clutch, that disappears as soon as I depress the clutch. By the time I reach the service center the sound is gone. It sounds normal. I have to keep the car overnight at the service center to make them listen to the whirring sound. I am very disappointed. It is my first new car. I am planning to change all the fluids again at the best MASS. I stand to lose around 4000 because I had just done all the fluid changes at my native place. advice me.

Hi!! .... When the sound goes by pressing the clutch, it has nothing to do with release bearing. Circulation of gear oil (or the lack of it!) is the cause and this is a very common issue!

This sound is known (i don't remember where this was discussed before) to be a lack of circulation of oil to the 5th gear. Once the gear box comes in use and the oil circulates, the sound goes.

I think, more than one of my cars has had this sound, but I never did anything about it and the cars never had an issue. If the noise is too much you might consider changing the gear oil, otherwise don't bother.

In my experience, many (but not all) Marutis make this noise, but how many people actually wait more than 1sec before driving off!

Exactly Sir, You have just relieved me. I am going to change the gear oil soon. Maybe it will not create any problems but in my mind there is still some turbulence. I will change to Total 75w90 this week.

Is the sound coming while stationary or when moving? If it is latter definitely not oil.

I have asked for clarification, if it is while stationary or not?

The sound is clearly audible when the vehicle is stationary and only when the engine is cold. When I press the clutch the sound goes away. I missed your quote yesterday, so I could not clarify the details. The sound is audible in a very quiet place in the morning only. After driving the car for 10 minutes the sound goes away.

Clutch or associated parts it is then. While stationary how would any other parts like gear wheels move inside the box? I feel its release bearing or associated parts. Quite common in many maruti cars

I have removed the stereo, so the noise was audible. But still do you think 80w90 gear oil will not cause any harm to the vehicle? I am concerned because 75w90 gear oil is recommended by maruti. I feel that the Reliance brand of gear oil is not trustworthy. I am planning to change it this weekend. I have already booked a bay this weekend and I am changing over to Total 75w90. I do not want to stress myself much over the car.

Change it if it is wrong grade, but a 80w90 is thicker oil so it would muffle more any gearbox noise, yes in cold climate it would take lil longer to circulate.

In short change oil for peace of mind, but the sound i strongly doubt is something else. So get it inspected by another mech. If its minor release bearing type sound, ignore it.

Try this- Rest your leg on the clutch pedal (or depress it slightly- about 5 cms), if the noise vanishes then it is the release bearing.
