ARTICLE: Synthetic oil vs Mineral oil

[Gurkha]

The best compromise is super heavy duty mutli fuel rated HDEO like DELO 400 which is ISOSYN Group-II or Delvac MX, both exceed petrol engine specs by miles and meet the top diesel specs as well. They come in 15W-40 and have excellent detergency and shear strength. UOAs reveal they perform as good if not equal to synthetics at less than half the cost. They can be used in motorcycles, gensets as well as your gas and diesel cars and SUVs. Change them at 6000km or six months, whichever comes first and hear your engine purr for miles.

Take a look at the attached pic of my engine at 117000km, from day only Delvac MX or Delo 400 used.

You never know with these local makes, what they would end up doing to the engines, quite possibly the opposite to what they promise if not worse.

EDIT: Just saw your post! COnfused...what oil helps in high rev, short burst, heavy traffic situations?

UPDATE: Bought 3.5L pack of Castrol Magnatech from Lajpat Nagar Delhi for Rs 830. Will be going for servicing in a day or two.

Small query: Can i opt for a oil flush even for a mineral to mineral oil switch? Would it get rid of all the much in the engine?

Thanks

It would only get rid if the muck is there in the first place. If there isn't....it is a waste of time + money.

Generally I won't bother with flushings when using mineral oil, as long as the engine has been serviced per manufacturer guidelines and schedule. But opinions differ on these matters.

I am planning to get Synthetic Oil for my Alto 1.1 from Mobil and its clocked 30K Kms. Which grade is better and can anyone suggest the grade to be used.

Is 15W-40 the right grade?
P.S: My ride is an Alto 1.1 which is a Wagon-R engine.

^^5W50 is the common grade for petrol cars.

I have been using Castrol GTX Diesel since 70K kms (API-CI4), and the engine is still purring on beyond the 100K mark.
Plan to get the Delvac MX from Khan market for the 104000 service, and will see the difference. Sector 16 Noida market does not have any good lubes except for tuned for petrol Shell Helix and Castrol Edge.

what has 5W50 to do with petrol or diesel. Its more to do with ambient temperature.
for example for somebody in Chennai 20W50 and 5W50 or 0W50 will give the same performance(everything else remaining same).
for somebody in Leh (0W40 or 0W30) will mean the same thing, since ambient temp will never go above 20.

Correct,man.
But, like I've asked on this same thread before, can you name a synthetic oil available in India other than the 5W50 /5W40?
Shell used to sell 15W50.But, now its replaced by 5W40.

Castrol EDGE is available in 15W50 I think.
Using 5W40 will be less beneficial than using 20W50 if you are the kind who likes their engine piping hot near the redline.

[CrAzY dRiVeR]

Is it advisable to use synthetic oil in bikes? Specially a P180 DTSi?

Read through the thread, but still in two minds as to which oil to buy for the bike.

[simply_sunny001]

This weekend i tried finding Delo 400/Delvax MX in my hometown Rohtak but to my surprise no one in the whole city stocks them.

so looking for Mobil and Chevron distributor in Noida/Delhi

Any pointers guys ?

Again. There are no 20W50 synthetic oil available.
And the 20W50 mineral that Im aware of is the WORST available in the market.Takes forever to lubricate at start up. 15Wx is far better and is used by garages and mechs all over.
The Castrol EDGE i've come across is 5W40.

[rohan_fonseca]

Castrol Edge i have is 10w50. Shell Ultrahelix if i'm not mistaken is 15w40

[nitrous]

^^Can you post a picture of the can,rohan?
I hope its not the motorcycle oil you're using.

[crazydiablo]

Shell Ultra Helix is now 5W40. Earlier packs used to be other grades.
