I too got the 80K service done for my Swift and cost me ~10K. EGR & intercooler cleaning done, plus de-carbing also done - rest usual all oils, coolant & filters relpacement. The car used to emit lots of black smoke under acceleration, and after all these tasks performed the smoke is still there but colour has gone white.

But in your case Switch, except the engine oil & filter - aren't rest of the oils/filters to be changed at 80K service?

You'll need to replace the bearings of the affected wheel only. I got it done for one of my Swift's wheels last year @ MASS & cost me ~750 bucks.

White smoke means oil is being burnt in the engine. Did you check if they have overfilled the engine oil? I only used to get white smoke when engine oil was overfilled as it used to get into the intercooler and then into the engine.

I was given the same reason by the SA for black smoke that oil must be entering the intercooler and hence got it cleaned. I went to him today morning for the white smoke thing and he said it should get settled down after driving for couple of days. And since I've hardly drive 15-20kms after the service, I'll wait for couple of days before I bang him again.

Until then, you can check the oil level on the dipstick if its overfilled or not. Let the car sit for some hours on a flat surface and then check the oil level. Should not be anything above the full mark.

Yes park the car for couple of hours on flat ground and use the dipstick to measure the level. Drain excess oil if it is anything more than the max mark. If you run the car like this, there is high chance of turbo oil seal failure. MUL has given strict notification to dealers not to overfill the DDiS engine. 3.1 liter max if its with oil filter change and 2.9 without. So if you need to drain and refill, fill only 2.9 liter since you will not be removing the oil filter.

Experts,

After having done clutch overhaul on my 4.5yr old Swift DZire Diesel at 51K km now[Vehicle stranded on road after cluthc became completely free and clutch plate, pressure plate, bearing, flywheel, seals, labor costed me 12K!!), my service advisor at Maruti dealer service center tells me that I should use these gear/speed combinations for fuel efficiency

above 10kmph - 2nd Gear
above 20kmph - 3rd Gear
above 30kmph - 4th Gear
above 40kmph - 5th Gear

However when I try to use these combinations the RPM is pretty low(like switching to 5th gear at 40kmph - the RPM is just 1200). Is it advisable to drive at such low RPMs as I get a feeling that engine/car is stressed out to move at that RPM?

Helpful recommendations are requested to maintain longer clutch life and fuel efficiency. Thanks.

The oil level is fine, got it checked. And the white smoke has also got settled now, occasionally it's there on hard acceleration but I guess it's normal for a 80K run diesel engine. But it's not so much as it was before, earlier I could hardly see anything in the rear view except black smoke while hard overtaking.

Clutch set changed at 51K? Is the car driven by drivers or man people including you? That mileage is low for a clutch change. I am still waiting for a clutch change on my Ritz VDi which is at 1.01 L kms.

For fuel efficiency I don't think the mentioned figures by your SA would help rather deteriorate the FE and engine.

Since the peak torque comes in at 2000 RPM hence the turbo spools I suggest up shift at 1800-2000 RPM. Just when the needle is near 2000 RPM up-shift. It keeps the car in the power band and doesn't lug the engine. Same while down shifting the moment the RPM goes below 1500 (say 1200-1300) down shift. While braking use engine braking sensibly. It will increase the brake pads life and give you that extra confidence. Don't overdo it else your clutch and gear box will go for a toss.

No it is not normal for any engine (let it have any number of miles clocked). I have not read the older posts (sorry for that) but I feel are the piston rings doing their job?

Seeing black smoke under hard acceleration is normal but NOT white in any condition. Get the car checked again by MASS. If you have any trusted mechanic or a MASS that has good reputation for service take it there and get them checked.

Anurag - No it's not white smoke anymore, normal black smoke under hard acceleration but now much less than before. White smoke problem is not there now.

Ah! Then it is fine! No need to worry.

Just keep an eye on the air filter too. Change it every 10000 kms and pressure (Air) clean it every 5000 kms to keep that black smoke under check.
It helps a lot. FE is also not affected much else a clogged filter drastically hampers the FE.

I have seen the above gear shift ratios mentioned in couple of MASS for better FE. However not sure if this is applicable for DDIS as well.

Normally by 45-50 I move to 5th gear. My FE within bangalore city is around 15 with 100% AC(last three are 15.11, 15.01, 15.53). I spend more time on traffic heavy Bannerghatta Road.

Will try doing the shift @1800-2000 RPM and see if that makes a difference.

If I'm not wrong fifth gear@1500 RPM the speed is 60 kmph. So 40-50 would be near 1200 RPM. That is quiet low buddy. I feel keeping the RPM above 1500 RPM and maximum 2000 RPM for fuel efficiency.

I up shift at dot 2000 RPM and down shift when the needle touches 1200 RPM. I get a mileage of 22 kmpl minimum.

I never had any intention to follow the gear shift ratio mentioned above. But I have noticed being around 50 when I move to the top gear. Again this may not be true even if there is a slight incline. Anyways will try to follow your method and see if I am able to increase the FE.

Regarding your FE, it looks awesome(Is it more than ARAI numbers by any chance?), wonder what kind of traffic you drive through.

For me, - during morning hours its a 5Km stretch which takes around 30-40mins. - during afternoon hours the same 5Km stretch takes around 20-25 mins. - and then a 20 Km stretch taking around 40-45mins.

The highest FE on highway is 22.01(speed around 80-100 with 100% AC + 3 Adults).
And its a previous gen Dzire.

Thanks everyone. So it looks like no one is suggesting upshifting from 4th to 5 gear at 40kmph, which is at 1200rpm. Upshifting and downshifting should be deiced by rpm than the speed. I normally used to do that and the max average I used to get in 50% highway, 50% inside roads was 17kpl..

Guys,
My swift D has done 72K kms and is little more than 4yr old. The FE is city drivings seems to have come down by a Km or so recently (from 15-16 to 14-15 level). the car is regularly serviced as per schedule and air filter is replaced/cleaned frequently. There is no other changes like tyre upgrade or change in driving style/route.
What would be the cause of drop in FE? The highway FE seems to be fine with around 18-19 in Kerala traffic.
