The latest generation of diesel engine oils from CHEVRONTEXACO ranging from API CH4 to CI4 ....PC 10 which the oil companies are working on is to improve the performance of the additives and viscosity index improvers under Exhaust Gas Reciruclation systems where the oil will be stressed to higher temperatures .

Under the above conditions the superior additive chemistry of (Chevrontexaco )DELO Gold which exceeds API CH4 performance and is made with Group II plus base stocks will solve your problems of temporary shear as the base oil itself is chemically pure of impurities and has a higher VI,which means higher performance of both base oil and additives.

I would suggest use of the above product for meeting the tough ambient temperature conditions of 40'C in India.

DELO Gold has been launched in India last week and is available in all Caltex Outlets.

Franky,
Thank you for your response, currently the Caltex distributor is carrying only Delo 400 15W-40, I have picked up a 20 liter drum for my vehicles. I have heard quite a lot of good thing sabout this CI-4 rated ISOSYNTH oil from fleet owners and personal vehicle owners alike. Do you think that the Delo Gold is a better product than Delo 400?

Franky,

I had sent the benefits of API CI 4 specs to Madhukar Patil Sales Head of Caltex-Chevron -India and am surprised that Delo Gold (a CH4 oil)has been launched in India rather than a CI 4 oil.

For the India market CI4 is the best oil for all terrain applications.

Hussam,

Caltex has been selling the Delo-400 in India since last year and it is a ISOSYNTH CI-4 rated oil. I am using it for the last two weeks and am quite pleased at the results so far.

Considering that the nearest monograde competitor in India being the Delvac 1340 which is still rated at CF-4, a CH-4 rated monograde is a credible performance. Most so-called multi grade oils commonly used in diesel vehicles in India are still rated at CF-4. The Delo in light of all this is certainly a superior proposition.

Gurkha,

First the clarification whether DELO Gold is superior to DELO 400 .

DELO 400 API CI 4 is a superior product and is considered as the world oil as it meets the latest requirements of all major OEMs across the world.

DELO Gold API CH 4 is one step below in performance and it may be the suitable replacement for the present grades that you are using.

Both the above products are based on ISOSYNTH technology patented by Chevrontexaco.

In any case DELO 400 SAE 15W-40 is one of the best products available in the world today.

Thats what I thought although a CH-4 rated monograde is quite a temptation in summer driving. The point is that I live in an area where it is quite cooler even during summers with the temps hardly exceeding 33c on a bad day but my work takes me to places where the temps are in the upper 40c region during summer, that is why I started the original post. Both my vehicles get their oil changed in the month of Jan and then July so they get mixed drving temperatures so my guess would be that Delo 400 should provide me with enough protection for all the extremes.

Gurkha - I live in northern Australia so I can understand your higher temperature operating conditions.

Alot of people will use the CH-4 and get brilliant results out of it. Your contending with more humidity, dust and ambient road temperatures - so engine cleanliness, anti corrosive etc is particularly important.

We run a 15W/50 for best results.

15W-50 has totally disappered from the market here in India, however Delo 400 is giving me quite good results so far, drove my OM-616 turbo in 50c weather with the engine temps nearing 95c and the oil held up quite well with no thinning out. It is in these conditions, I would appreciate the 50 weight.

Gurkha,

Whatever brand you choose.Ensure cleanliness
level(ISO-11171)is 16/13.More cleaner the oil
kept,wear will be less,improves fuel consumption
increases engine life.Are you getting the fresh
oil tested for particle count analysis?

Bala,

I have no idea where in India I can get my oil analyzed but I do change my filters at 3000Km and change my oil at 6000Km max. Having driven my other OM 616 to around 500,000Km there was no sludge deposit in that engine when they opened it up for overhauling it.

Gurkha,

You can seek oil analysis from your lube supplier. Castrol did it frequently for its premium customers at no cost.

Predict Technologies offer a very good wear metal analysis based on Ferrography. They charge around Rs 1000 to 1200 per sample.

IIPM Kansbahal, near Rourkela, Orissa also conduct lube analysis. They charge around Rs 1200 or so for each sample.

Gurkha,

Oil analysis through Labs for personal use is an expensive affair. It is best utilised by corporations with large fleets. For a vehicle owner whoese main use is personal it is best to obtain the analysis from the Lube supplier.

If Caltex-Chevron conglomerate in India is worth its salt, they should be able to give you the analysis for the Delo series. Caltex operate through Chennai in India. If they a full fledged lab in India in thier manufacturing unit, they should be equipped with ICP Spectrometer for wear metal analysis. An MNC committment is decided by its investments. Otherwise ??????????

There are a number of labs that can do Oil analysis. Only a token few can provide wear metal analysis.

WEAR METAL ANALYSIS
1.India Institute of Production Management (IIPM).
Kansbahal - 770 034, Near Rourkela, Orissa, INDIA . Phone -06624-280322/948/576 | FAX : +91-6624-280122. Website

FERROGRAPHY
2. Predict India - Lab at Hyderabad,
Contact Mr.S.K.Mehta, Managing Director
skm@predictindia.com or info@predictindia.com.

Trust you find the info useful.

Hi there,

As a Lubricant specialist my choice of oil will not depend ONLY on SAE number, 30, 40 or what ever. All the SAE number defines is the viscosity of the oil.

Over the past decade Engines oilS have become multigrades. All this means, the oil can possess the viscosity of a range of SAE numbers, 20w/40 etc..

Current trends show that a lower viscosity oil 5w 10w and so on have reduced energy consumption. They are also pumpable at fairly low temperatures.

The crux of the matter is to choose the oil (petrol or diesel) with the highest performance. API has issued a coding/nomenclature for a series of performance related tests. At the initial stages the SA and CA (for petrol and Diesel) were straight minerial oils with little or no additive package. Today we have SH and CI4 type of oils that belong to the top rung in performance.

Incidently, the makeup of the new generation of oils take into considerations the viscosity (SAE number) of the oils. If I were in a cold place like Canada I would rather opt for 0w/xx and 5w/xx or 10w/xx for the rest of the world.
