Roelf,
My suggestion will be go to HELIX. I went that way and no problem thus far. As to the viscosity?? I do not know but would suggest to go for a slightly thicker oil. Our outside temp is on average much higher that that in Europe and Japan. Unfortunately, the thicker oil is not always available.

Gents,
The DELO 400 is in. That motor purrs like a kitten. Couldn't get my car out of the Tech's hands. He had other guys there listening to the V6 idle. In the end I had to sit in the passenger seat while he drives my car to his home after work.
I have no doubt that the Helix is a good oil and not even suggesting the DELO is better. All I know is that I just luv the way that little beast is behaving with the new spark plugs, timing belt and DELO.
The tensioner that was removed had a tiny oil leak and the Tech says it wasn't functioning properly. The belt had tiny cracks if you bend it open and the plugs looked like they could go another 90k - no carbon, oil or soot.
John, if I cruise at a steady 120 on a flat road and no wind, then 13L/100km is on.

Hello everybody not bored to death by now about oils,
Chevron (the guys that designed DELO oils) is one of the biggest oil companies in the world. Their technical specialist tried to explain me the difference of oils used for diesel engines and petrol engines and the big difference is the additives to counter the sulphuric acid build up (caused by diesel combustion)in a diesel engines. Most oils used in diesel engines is oils with higher specs than those used in petrol engines. His answer was that most oils for diesel engines can be used in petrol engines but they (Chevron) designed DELO to make life easy for the fleet owner with diesel and petrol driven engines in his vehicles.
By the way, DELO 400 Mulitigrade is a synthetic oil. The base oil that they use to make DELO 400 is a synthetic oil.
Roelf, I am clad to hear that the engine is running like a clock. Look in your Owner's Manual, the table for the oil to be used at different climatic conditions is difficult to understand by first glance but study it a while and it becomes clear what oil you should use. 15W 40, is what I understand, is the oil we must use in South Africa.

Look here.All lubricants in the Delo® Advantage range utilise ISOSYN® technology, a patented process that purifies and refines mineral base oils by removing impurities and contaminants such as nitrogen, sulphur and wax.
ISOSYN® mineral based lubricants provide performance equivalent to synthetics, at a lower cost.
BOBTHEOILGUY says:
The iso-syn method you referred to is the patented refining process that is used by Chevron to produceits base oils. This process is a hydrocracking process that consists of the follwoing steps
The first step in this process is atmospheric and vacuum distillation.
The second step in the process is severe Hydrocracking to remove the majority of sulfur, nitrogen and polar compounds and saturate most of the aromatic and naphthenic compounds that may be present.
The next step is Hydroisomerization which is also known as Isodewaxing.
The Isodewaxing process which is patented by Chevron takes n-paraffins and other molecules with waxy side chains and converts them into isomerized branched paraffinic molecules (isoparaffins).
The Isodewaxing process can also use wax produced by solvent dewaxing as one of its feedstocks.
The third step is severe hydrofinishing which is used to remove any remaining sulfur,
nitrogen, polar compounds and unsaturated molecules.
The final step is atmospheric and vacuum distillation to produce the desired viscosity grades.
This process produces Group III UCBO base oils that have viscosity indexes ranging from 120 to over 140.
The advantages and disadvatages of hydrocracked base oils are as follows:
The careful selection of the proper base oil remains the key to the formulation of a quality finished lubricant. Contrary to much of the hype taking place in the lubricants industry, hydrocracked base oils are not a panacea.
Very good to excellent oxidation stability due to their high saturate content.
Very good low volatility characteristics due to their high saturate content and the lack of lighter molecular ends.
Very good response to oxidation inhibitors and pour point depressant additive systems.
Light color and clear in appearance – Water White in color.
High natural Viscosity Indexes ranging form 95 to 140
The hydrocracked base oil’s High Viscosity indexes reduce the amount of viscosity index improver need when formulating a multi-grade oil. This improves shear stability.
Very good low temperature properties especially those Group III base oils that are produced by the Isodewaxing/Hydrocracking process.
Very good to excellent thermal stability due to their high saturate content.
Low carbon residue forming tendencies.
Very good to excellent demulsibility characteristics due to their low polarity.
Low toxicity due to the absence of impurities. Some hydrocracked base oils are pure enough to be used in cosmetics, pharmaceuticals and food grade oils.
Hydrocracked base oils can be used as correction stocks to improve lower quality base oils.
Lube oil base stocks may be manufactured from inferior (non-lube) crudes.
Hydrocracking produces highly sought after by products such as naphtha and middle distillates.
Hydrocracked base oils do not contain any of the natural sulfur antioxidants that are needed for oxidation stability.
Hydrocracked base oils generally require the use of additional oxidation inhibitors.
Once the oxidation inhibitor additive package is depleted rapid oxidation will occur.
Uninhibited hydrocracked base oils will darken and form sludge when exposed to air and light.
Hydrocracked base oils have a low ability to solubilize the byproducts of oxidation.
This can result in the formation of sludge and rapid depletion of the oxidation inhibitors that are present in the lubricant formulation.
Hydrocracked base oils exhibit low solvency characteristics than other types of base oils.
Without formulation adjustments additive solubility can be marginal and some additive
drop-out can occur
This lack of solvency characteristics also inhibits hydrocracked base oils’ ability to
dissolve, disperse and hold sludge and deposit forming materials in suspension.
Hydrocracked base oils due to lack of aromatic compounds require the use of seal swell additives in order to protect seal quality.
The hydrocracking refining process produces predominately low viscosity base oils due to the cracking of heavier molecules into smaller lighter molecules.
The highest viscosity grade available from the various producers of hydrocracked base oils is equivalent to an ISO 100 or an SAE 30 grade.
Hydrocracked base stocks can not be used in the formulation of many high viscosity industrial and engine oil products without being blended with other types of base stocks such as Group I base oils or the use of viscosity index improvers.
Additional refining methods such as such as severe hydrotreating is required to stabilize hydrocracked base oils
Initial investment costs and operating costs are higher for hydrocracking units.
Highly aromatic by products suitable for use in carbon black or rubber extender oil manufacture are not produced.
The Isodewaxing/Hydrocracking process does not preserve wax volume or wax quality
because the wax is converted into lube oil basestocks and fuels. This results in less wax and wax-like products for resale.

For those interested in more details about oils please read the article on the web page (like given below):
http://www.baseoilmarket.com/oil.php
This is a subtraction out of the above article:
"Group I - Solvent Freezing: Group 1 base oils are the least refined of all the groups. They are usually a mix of different hydrocarbon chains with little or no uniformity. While some automotive oils on the market use Group I stocks, they are generally used in less demanding applications.
Group II - Hydro processing and Refining: Group II base oils are common in mineral based motor oils currently available on the market. They have fair to good performance in lubricating properties such as volatility, oxidative stability and flash/fire points. They have only fair performance in areas such as pour point, cold crank viscosity and extreme pressure wear.
Group – III Hydro processing and Refining: Group III base oils are subjected to the highest level of mineral oil refining of the base oil groups. Although they are not chemically engineered, they offer good performance in a wide range of attributes as well as good molecular uniformity and stability. They are commonly mixed with additives and marketed as synthetic or semi-synthetic products. Group III base oils have become more common in America in the last decade.
Group IV -Chemical Reactions: Group IV base oils are chemically engineered synthetic base stocks. Polyalphaolefins (PAO's) are a common example of a synthetic base stock. Synthetics, when combined with additives, offer excellent performance over a wide range of lubricating properties. They have very stable chemical compositions and highly uniform molecular chains. Group IV base oils are becoming more common in synthetic and synthetic-blend products for automotive and industrial applications.
Group V - As Indicated: Group V base oils are used primarily in the creation of oil additives. Esters and polyolesters are both common Group V base oils used in the formulation of oil additives. Group V oils are generally not used as base oils themselves, but add beneficial properties to other base oils. Some examples of Group V Base Oils are: Alkylated Naphthalene, Esters, Poly-alkylene glycols, Silcones, Polybutenes."

A second read made some lights go on for me. It starts off with lots of praise in the pro- section. Then the worries start about the
In the end it seems the answer is to keep an eye on the colour of the oil and make sure you don't over extend the service interval. This of course goes for any oil in any car.
A co-worker has just lost the motor in his wife's Chev Something 1600 platkar. On opening the engine they found some oil ports were sludged up and some of the engine components were starved - teminally so
. When I grilled him a little on their service habits, he broke down and confessed to the fact that they are terribly slack in getting their cars serviced. I have now convinced him to bring his 2.7i Hilux 4x4 to my place for a quick oil and filter change, before it follows his wife's car to the cemetary.
I'm absolutely and for sure going to reduce the service interval on my car to 10k.
Thanks for all the valuable and interesting input thus far.

Hi Roelf,
I can promise you the 4E's is not sponsored by Delo or get commission on sales !
If you go and read about Delo 400 you will see that they counter all the bad stuff with aditives.
I had such good results with Delo that it is hard not to promote it.
Last week I bought my daughter a second hand Corsa (48 000 on the clock. Serviced it and obviously used Delo 400 multigrade. After her first trip (after the service) she asked me what did I do to the engine that it is running that quietly.
I only changed the oil, oil filter and ear filter.

Roelf,
Yes, that discussion will only make sense to scientists in the petro-chemical industry!
Remember the oxidation stability refers to the base oil. Delo400 has additives that correct this 'shortcoming'.
See the attached Spec Sheet.
Also read here to evaluate the quality of Delo400, as measured against full synthetics.
Yes, sludging can kill an engine very easily. The GM 4-cyl engines are renowned for this failure.
On the colour of oil: If it slays 'clear' after some usage, it is rubbish oil! Good oils pick up the sediments, and keep them in suspension for the filter to sort out.
Two of the major benefits of Delo400 are the de-sludging, and keeping the sludge in suspension.
I would suggest an 'early' oil and filter change (in case the Delo400 loosened some sludge), but after that, there is no reason not to stick to the recommended oil changes.
In fact, Delo400 is reputed to extend oil changes (based on oil analysis), rather than shortening them.
