Cheers!

It must definitely be superior! But may be also because the difference in "thickness" is not too much between the two.

[rkguru]

For Indian weather, 20W40 is sufficient. 15w40 is better when required in very cold states or still can be used overall. Anything lower than this is of not much benefit.
Definitely should not go to 10w30 or lower, as the higher reading should still be 40.
The API grade needs to be greater that SF for petrol and CD for diesel.

[nitrous]

^^API-CD is archaic, bro.
Atleast CF+ is what I'd recommend.

[rkguru]

Sure Nitrous, I agree CF is what should it be at least.
People however beware there are oils still available
with API SC/CC grade.

[Raccoon]

They are advertising Servo MGO right now, in the top banner! I don't think this is the best place to advertise it...

[Gansan]

Check out the "performance standards". Even here it is advertised as API SC/CC. Whereas as per Maruti manual it should be at least API SF. And this is what they use at MASS.

yes, it is only the ambient temp or cold start viscosity that differs by a grade of 5. Operating temp viscosity is the same i.e. 40. That said, additives also make a difference to many factors that define an oil's performance.

Guys, the second free service of my Alto falls due by Christmas time. As per the manual the next oil & filter change is due only during the third service (first change during the first service, and subsequent changes every 10k KM/12 months thereafter). The recommended oil is MGO 20W40, API-SF, but I changed the oil with Shell Helix 15W40, API SL during the first service. The car has done only 1800 KM since then.

During a recent visit to my MASS I made the SA check the oil. He says the oil is good and there is no need to change till the third service/10000 KM, whichever is earlier. Given my current usage, the odo may at the most touch 7000 KM by the third service. I have the following doubts:

a) Shall I change the oil now anyway or wait till the third service?

b) If I decide to change now, shall I buy a 4 litre can of Helix super May'09 batch (not HX5) from the Shell station? Because I have about 1.2 litres balance oil of the same batch from the previous oil change. Shell HX5 only is being sold now, and they have only one can of this older oil left.

I will have >2litres of oil left over after this change. Can it be used during the next change in June, as the oil will be 1 year from date of mfg by then?

Change at 10,000kms/1yr, whichever is earlier.

Hi I am giving the ANHC for the third service next week. The car has done about 7 k. Is there an oil chnage scheduled. If so which one should i ask them to select.

Hello nitrous. My car [Zen Estilo Vxi] is 19 months old now. It has recently clocked 10,000 kms. The car is still running on factory fill. It is giving me poor fuel efficiency, 10 kmpl in the city and 13-14 on the highways. Does the oil have anything to do with it?

Which make/brand do you suggest? The MASS guys told me they refill Castrol Magnatec. Should I go for this?

A friend of mine is suggesting me mobil1.

Please help me.

Referring to your owner's manual would be best.

Just got back from an oil change at TASS. Castrol edge was available for whopping 4300 for 4 litres. Sounded too expensive and i decided to stick with the mineral GTX at 231/- for a litre. Total of 3.2 litres at 3rd service costing - 1240/-.

just chill and change the oil after you have done with your christmas celebration 500kms here and there dont really make a difference to the engine and since you havent clocked too many kms so no need to worry dont take tension and enjoy the festival.
once you are done then give your car for a proper service and change the oil and the filter.

also dont use the previous oil and also NEVER use oil which is of 6 months and older date of mfg. Go for maruti genuine oil(20w-40) if you cant find any other brand which suits you.

remember one thing the car company has thought a hundred times before sugesting osmething for their product to last! and maruti is a very long lasting car.

Sound decision to stick to mineral, there is no need to spend that much money unless you are a rallyist or something, better spend the savings on some accessory!
