1)Thicker oils are not necessarily better than thinner oils, unless and until manuf. of the car recommends it.
2) Heavy oils tend to stick longer to parts between two moving surfaces, and this degrades the oil faster than a lighter oil that flows better, allowing fresh oil in its place sooner.
3) Cold weather has a thickening effect on conventional oil, and this is one reason thinner oils are manufacturer recommended in places with cold winters.
4) Engine designs are constantly evolving to allow the use of even lower-viscosity oils without the risk of excessive metal-to-metal abrasion, principally in the cam and valve mechanism areas. In line with car manufacturers push towards these lower viscosities in search of better fuel economy, on April 2, 2013 the Society of Automotive Engineers (SAE) introduced an SAE 16 viscosity which now maruti recommends it viz.0W16
5) Lower-viscosity oils are common in almost all newer vehicles. They will not lower the life of engine.Why would manuf.want to damage engine intentionally with thin oil and bear warranty cost of all car repairs?

Yes, a low viscosity oil won't damage the engine..(Unless it is not recommended). Its just a myth..In reality, it provides more protection in colder conditions...

June 2020 - Oil Change Time

With extended long work hours and weekend job schedules, took the car night itself with the plan of changing and it rained. Decided to change next morning saying some lame excuse from work. Just 30 min max job.

2020-06-03 00-39-29.jpg


Next morning, jacked up the car and spread some newspaper in case I screw it up.

2020-06-03 10-54-27.jpg


Found my DIY oil pan from trash.

2020-06-03 10-55-46.jpg


First roadblock. Overtightened drain bolt. Had to fiddle with it a lot to let it go. Dunno why these morons always mess with it.

2020-06-03 10-55-01.jpg


and drained the oil.

2020-06-03 10-56-51.jpg


Next, oil filter. They "super" tightened it as well. No way it was giving way. Last time oil was changed at Travancore Motors. The same people who installed Opel Corsa air filter in Fiesta.

2020-06-03 10-55-09.jpg


Filter wrench was slipping. Filter base lost its shape. Tried wrapping in rubber and cloth and wrenching and it didn't work. Tried pipe wrench, failed as well. Now either I have to get the mechanic home (which as usual ego didn't permit), or to filter and pour back the oil and take to the garageas if nothing happened, or the last option, the old school way, puncture the filter, but if it fail, no way to get the car to garage.

2020-06-03 11-25-45.jpg


Took the widest minus screwdriver I had and my Thor hammer and hammered it in and rotated it. At first, the filter was deforming instead of rotating, that much tight. Filter O-ring was kind of flat and flush with the surface.

The dirtiest oil change in my life. Even the dailies couldn't help.

2020-06-03 12-06-27.jpg


New filter.

2020-06-03 11-58-44.jpg
2020-06-03 11-58-33.jpg


Clearly mentioned how to install. Dunno why the idiots don't follow these. Even the trainee would've installed minimum 100 filters in his apprenticeship.

2020-06-03 11-58-39.jpg


Properly installed. Hand tightened and wrenched to the point of decent tightness, less than a full turn.

2020-06-03 12-06-40.jpg


New SGP drain bolt. Smaller head compared to older MGP one. 14 mm vs 17 mm.

2020-06-03 11-01-32.jpg


Longer as well. Aluminum crush washer instead of copper. See the amount of Teflon tape used on the older bolt. They would've screwed it up during install.

2020-06-03 11-01-47.jpg


Installed the new bolt.


2020-06-03 12-07-08.jpg


Looks like needs flushing. Next time.

2020-06-03 12-10-03.jpg


Valvoline.

2020-06-03 11-58-26.jpg


Big funnel I got from neighborhood supermarket. Never fitted the bikes. Perfect for car.

2020-06-03 12-10-13.jpg


Thick and gold. Pour till the last drop [evil]

2020-06-03 12-14-48.jpg
2020-06-03 12-15-12.jpg


All the weapons used to remove the oil filter. Start to end took 2 hours.

2020-06-03 12-17-55.jpg


Capped up. Idled and confirmed level. 3.5 L is perfect. Manual says 3.7, may be for dry fill. Service centers fills 3.1-3.3 L. I insist them on 3.5 L.

2020-06-03 12-23-26.jpg


Mechanic coupon. Expired as expected. Mechanic gets the 7th can for free.

2020-06-03 12-22-33.jpg
2020-06-03 12-22-38.jpg


Old oil collected for disposal. Friend of mine comes to collect it for his concrete casting work.

June 2020 - Continued

Installed new air filter. Mandatory old vs new shots. Around 15k km done on old one.

Started developing oil leak as expected due to the "extraordinary" workmanship of the previous garage. And as expected, from the drain bolt itself. Loosened a bit and applied some clear gasket maker and tightened up. No leaks till the time of posting.

2020-06-15 22-53-40.jpg


No leak from oil filter.

2020-06-15 22-53-46.jpg


Easter eggs. Found the old logos inside glove box. Thought the garage guys took it.

June 2020 - Coolant Topup

Mixed the Ecstar coolant and distilled water in 1:2 ratio.

2020-06-04 11-40-29.jpg


Coolant tank is easily removable, just have to move out the air filter intake, which is held by a 10-mm bolt. Tank has no screws or bolts, sits on the battery bracket.
It can be topped up without removing, but I prefer cleaning it every time.

2020-06-04 11-52-22.jpg


Not rusty like usual. Level drop was also minimal.

2020-06-04 11-50-03.jpg


Washed off the reservoir of any debris, just traces of fine sediments, not big particles.

2020-06-04 11-48-51.jpg


Filled to Full Marking and installed back.

2020-06-04 11-50-36.jpg


Surprised to see it's still green for a long time. Usually it'll turn rusty despite many garages fixing it. Travancore Motors did some repair of the coolant system and it's working fine. No level drops or colour change.

2020-06-04 11-53-02.jpg


Let there be light - lit up for late night work/wash.
