More information about Mobil Delvac 1 (5W 40) which is fully synthetic.
Mobil Delvac 1 5W-40

Question w.r.t link given in one of the earlier posts on API ratings:
API Oil Service Categories

CF-4 Current Introduced in 1990. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CD and CE oils. CF-2 Current Introduced in 1994. For severe duty, two-stroke cycle engines. Can be used in place of CD-II oils. CF Current Introduced in 1994. For off-road, indirect injected and other diesel engines including those using fuel with over 0.5% weight sulfur. Can be used in place of CD oils.
CF is mentioned as introduced in 1994 where as CF-4 is introduced in 1990. So which is the latter standard ?. CF-4 or CF ?.

Also CF-4 is mentioned as applicable for naturally aspirated and turbo charged engines whereas that is not mentioned for CF.

I am currently using Castrol Edge 5W-40 for my Swift VDI which meets API CF standard (owner's manual mentions that the oil should meet API-CG-4).

Castrol Edge being sold in India is manufactured in South Africa.
They do not mention whether its for petrol or diesel engines.

"For prestige & High performance" is the slogan.

Is it okay to use this engine oil for Swift VDI ?.

Regards
Ravi.

My car has done 15K km. Should i go for Castrol Magnatec or Mobil 1 for the FIAT 1.6 Petrol Engine. And is the 15W40 avaiable for these brands. Is there any advantage / disadvantage in going for 10w40.

HELP!

HELP!

Mobil 1 definitely, smoother and silent engine.

Try 15W50. You are in trivandrum, so you don't need 10W. The upper number should be 50 instead of 40 as it will give better protection to engine at higher temperatures.

Thanks guys. But going through the mobil site i have a feeling that these oils are not 100% synthetic. THe only place they mentin 'fully synthetic is for delvac which is recommended for diesels. ALl other oils they have played safe by just mentioning "performance synthetic engine oil". I guess there should be sme thechicalities in not using the "fully synthetic" tag for the petrol engine oils. I seriously think they should be semi-syntehtic with additives. Please confirm if you have any idea.

Also i find only a 0w40 and 5W50 in the mobil range of synthetics. the recommended oil by fiat is 15w40. dont you think that higher (50) rating could be a issue .

Hi all,

Wnated to know from 'Oil Gurus' whether it is ok for me to change over to Synthetics for my Indica (Diesel), which has already done 84.5k kms.

I know most of you would advice against it because the 'flushing' procudure removes carbon deposits, which would have otherwise acted as sealant of sorts.

In my case, I have already got the engine flushed at 82.5K, though not with the intention of switching over to synthetics. I have not seen any major change(read decline) in performance after flushing procedure.

So, now that I have already flushed the engine, is it ok to switch to synthetics during my next service at 87.5k Kms?

Thanks in advance

[tsk1979]

No need to flush again, you can switch over to synthetic oil at next change.

[CaAT]

Thanks Tsk,

Few more questions

a) Which synthetic oil grade would you recommend for Indica
b) Would I require a special oil filter for synthetic oil, or do I continue with the regular one?

TIA.

One question. Seeing that you have already completed 85,000 kilometers using mineral oil, why change now? the extra expense of the synthetics will not really make sense at this stage of your engine's life.

Personally, if it were my car, I'd continue using high quality mineral oil.

[tsk1979]

I agree with rtech here.
I use high quality Mineral oil (Shell super diesel API-CG or Castrol GTX Diesel(API-CI4)
My indica has done almost 89K
Change oil every 6000kms. you don't need to spend that much.
