Nice update.
Good to see that the car is back as per your taste.

Jaggu.

Both Servo and Delvac are 15W40 which means identical working temp range. Isn't it ? So weather shoudn't be a factor.

Why is Maruti suggesting Servo in the first place, is it only as an alternative if Mobil is not available or can it be safely used and the engines put under same stress, especially in our demanding driving conditions and weather?

At the moment, Maruti suggests and demands MASS to use Mobile Delvac Super and not Delvac MX.

With these torque machines, the gear shifts has to very precise to get good 0-100 timings. IMO its not the right way to analyze the engine performance.

I think its just in your mind. You really re-define the word "pampering" for cars.

My observations:
Servo is slightly thicker, and darker compared to Delvac. Delvac is oh so baby oil kinds while Servo feels more like dabur hair oil.
It seems to have a distinct stickiness between the fingers compared to Delvac. Delvac on the other hand is one bad *** to wipe off from fingers where as Servo came out with just a wipe of paper.
When heated up, Delvac definitely seemed to hold its consistency without much change, apart from the risk of burning the finger! Servo on the other hand was like a goovy stuff.

Correct me if i'm wrong.
Aren't the above two statements in bold contradictory to each other?

The pricing of the oil is set by Maruti Udyog, dealers don't have a say in this.

May be true for DDIS. But IMO the extreme weather conditions are here up north, Bangalore though crowded still has a pleasant weather.

I will let all this pass and take it as one darn expensive flush job with Servo!

Found out that the oil filter cap "bolt head" has lost 2 tooths, one had disappeared 2 or 3 services back, it will cost some 600 bucks and unfortunately RNS Hosur didnt have it in stock. Didnt want to risk and get stranded so filter was not removed to do a complete drain. Instead waited a lil longer for all the oil to drip out.

Chetta

IMO u should have waited and got the filter changed as well.

Reading through the whole service episode again makes me feel MASS didn't replace it with genuine Servo CH4 oil.

[condor]

Jaggu : @ Condor: If you are changing to delvac mx, feel free to collect 2 liter from me. Batch is slightly old Sep 06 but was a sealed can and was stored properly away from heat/sun etc. Picked it up since 3 years is safe shelf life for engine oils according to car bibles

@Jaggu, thanks : 2 liters makes sense, since I can pick up a 5 liter can to come close to the 7.7 liter requirement I have. The truck's due for an oil change in June.

kpzen : The pricing of the oil is set by Maruti Udyog, dealers don't have a say in this.

But the oil will be bought by the dealers by the barrel, from Indian Oil. It's not a MOS to be supplied by Maruti. So you know where the profits go.

Mone, drive a car with delvac put servo in it and have another drive and see for yourself, it doesnt require expert senses to make out.

We are not talking about Getz CRDi here, are we? dont want to get into a comparison which engine is more complicated, has better tolerance, tougher, better engine here. Only time will tell that.

Jaggu.

Both Servo and Delvac are 15W40 which means identical working temp range. Isn't it ? So weather shoudn't be a factor.

Check for flash point, temperature diff of 5-10 deg means alot then, its not as simple as 15w40. Again if your car has EGR Servo is not the best, read up, enough amount of info on this from different sites. Start with car bibles.

At the moment, Maruti suggests and demands MASS to use Mobile Delvac Super and not Delvac MX.

But MUL uses both super aka 1300, Servo and MX i have the bills to prove. If you read back, i have seen the email from Maruti to RNS, which recommends Servo also! with email ids and not just another print out!

On the other hand the difference between Super/1300 and MX is almost zilch, actually for certain europen norms for emission MX is better. Please read the detailed spec from Mobil site for more. Again dont get carried away with Mobil super specs from other countries which will say CJ+ also, its different to ones sold in India

Chetta

Aniya maybe yes am nuts, but i think i have had enough oil flow inside my cars engines to know if it really makes a difference or just a placebo. Different story all together that some engines dont like certain oils even if they are better.

Reg the statements, let me clarify/communicate more clearly, though Servo "seems" to be sticky it might not be really great in protecting since it comes out with single wipe! ON THE OTHER HAND Mobil has a better adhesion which means protection. A very unscientific observation by me using my hands! nevertheless its evident. ps: its my way of writing, lil sarcasm and bad humor, kshemi lol

Why dont you try a better oil in your car, you might really jump up and down in your ownership thread with a better top speed. Effect of servo on ddis cars running up north as well as south of blr will definitely be more adverse. Now you know why we love this city Dealer hasnt fooled me since first thing i check is how the oil is after service.

Filters part yes, but i have done the extra bit to get oil out and the position of the filter is such that it doesnt hold much oil once the drain plug is removed in ddis. Observe an oil change and you will know. Its inverted sits on top (almost at the level of engine head) and its very diff construction compared to your common filters out there. But still i could have put the extra effort and no denying that or suggesting to anyone.

Yes and yes to the above. Will hand over the oil ONLY IF YOU DONT PULL that stunt, like you did last time around!

[Thad E Ginathom]

I had a practical demonstration of what difference an oil can make. This was about 1990, and I had a VW Golf (not a fancy one, but it was nice, and I was its first driver) as a company car.

There was a nagging problem when changing between two gears (I forget which) making that particular change stiff and difficult. When I took the car for service, they said they would drain the gearbox and refill with synthetic oil. I was really dubious that this could make a difference to what felt like a mechanical fault. They assured me that it was the first thing to try, and that, having been logged within the warranty period, the problem would continue to be covered if it was not fixed.

It was totally fixed. The replacement of this liquid moving part in the gear box made for immediate smooth and easy gear changes.

What's more, it made the stereo sound so much better too.



(just kidding on that last point)

[condor]

Jaggu : Will hand over the oil ONLY IF YOU DONT PULL that stunt, like you did last time around!

Awrighty. May be I'll think up something new then !

[Jaggu]

Thad actually it improves my stereo also Let me explain, my Pio has some noise correction built into it, by which the HU raises the volume when other noise in the car increases. Voila so with a more silent engine no unnatural tweaks from stereo giving a better sound!

I checked the IOC site again, apparently they make oils specially for Skoda and Hyundai Crdi. Skoda one has better specs so for IOC fans, a better bet. Hyundai Crdi ones are same as PRIDE XL

Seriously KP am not saying it will harm your cars engine anyway, but try out a better oil, especially since its running Pete's and all. You will have a better performing car and its not expensive at all, so you can have frequent changes without worry on pocket unlike a synthetic brew.

[Jaggu]

In short forget the huplaah about Delvac/Super etc, just the spec change from CH4 to CI helps. So ensure you get higher spec oil irrespctiove of brand. I had done a random check on Castrol, Shell etc in India, none of them had better grade stuff for Diesels Petrol cars are luckier!

Hope i have given some scientific info gathered from Mobil site, yes it has marketing funda's alright, still they would have done some amount of R&D before they put this up.

ps: info is dated 2004, so Super which was launched later should be better.

CI-4
The key performance advantages of reformulated Mobil Delvac MX 15W-40 include the ability to withstand higher temperatures, handle increased amounts of soot, and reduce corrosive and general engine wear. Now, more than ever, Mobil Delvac MX 15W-40 extends engine life!

HEAT - Modern diesel engines run hotter which can reduce oil and engine life. As oil oxidation rates typically double with every 10°C increase, lower quality oils will degrade faster resulting in viscosity increase and acid generation. New Mobil Delvac MX 15W-40 provides over 25% more protection against oil oxidation than an API CH-4 oil.

WEAR - Changing combustion control designs are increasing loads, soot and acid generation in modern diesel engines. These new designs can introduce combustion gases to the oil that can form corrosive acids. These are most aggressive towards softer metals found in bearings and bushings, but other engine parts are vulnerable. Mobil Delvac MX 15W-40 reduces corrosive wear at higher operating temperatures by resisting oxidation and improving bearing protection by more than 20% compared to an API CH-4 oil. In addition it provides added protection to other parts.

SOOT - Increasing soot levels are common with many modern diesel engines and hard-working older designs as well. Inadequate soot handling can shorten drain intervals, increase deposits and cause wear that can shorten engine life. Mobil Delvac MX 15W-40 provides over 20% better soot-related viscosity control than an API CH-4 oil. Exceeding API CI-4 Performance Standards.

Your stereo has a Service Level Agreement? Wow!

but I have heard of HUs that adjust volume against car speed, but simply measuring ambient noise sounds simpler and more effective. Must watch out for that if I ever get around to that sound system (its been two years)...

Jaggu, Is this applicable to the Indica Vista Quadrajet? My Brother In Law's car has clocked 5000 kms and is due for a service.
