Diesel is cheaper in the long run, gives you more miles/gallon, and more power

Yes, that is true but at what cost is it cheaper? When you see the colour of the diesel, you will be afraid to pour it inside your 2012 Autobiography that you are planning to bring in. This Range is similar to yours in LHD and the cost of repairs is not funny to the owner

Sooper, can't one find the 2010 Autobiography anymore in the market? I learnt only 250 were produced. All I find is from 2012 and they are so expensive.


By the way.... all dis gist don dey weaken me o. I don't think I need a ride that'd be taking me to a workshop every now and then. I understand it is a strong and powerful vehicle and I love it, but why can't it remain strong and less problematic. Abi mek I back off?

There are many autobioghy around and they are not problematic . It is our fuel that is creating these problems. The diesel version suffers from the same poor diesel quality that has destroyed all those new mack trucks that used to ply our roads. But when you use better additives for both versions, no need to fear, it is a strong and powerful brand and it is the only Brand on the road right now. All the others are crawling on the road looking for where to be Parked.

I know bro but I'm lucky I live and have links to England and thus is the birth place of The Range Rover.I can get any parts I want . So service parts won't be a problem even if I'm in Nigeria I can still order

U kno diesel engines are very tolorant to bad fuel .

fine

That is true, i am getting parts now from Bearmach and will be able to make the autobiography cruise around town.

Diesel Range rovers are becoming a reality in a country where the diesel is not bluetec or clean diesels, where all the new mack trucks are disappearing from our roads because of the poor quality and adulterated diesels. Unless there is diesel exhaust fluid commonly sold in the country, owning a diesel range is desirable. I have seen the autobiography sports a lot, the little luxuries in the interior makes one confused. Who is it intended for? The driver or the man sitting at the rear? I hardly see anyone with a range sport sitting at the rear while being driven by a driver, maybe 2 owners of autobiographies but no one wants to give his range sports to his driver, he takes charge of the thrills himself and so the autobiography in a sport does not match the autobiigraphy in a range rover vogue and i believe that is why no one is talking about it.

correct.The Diesel is the way 4ward,Im hoping we get tolerant with Diesel Engines soon.

good morning sooperrescue...I have a range rover 2003 upgraded to 2010. scanned got codes
p0021 vanos actuator fault...
P0171 system too lean bank 1 and
P1173 air leak to inlet bank 1. what do dey mean?

P0021 is telling you that the timing has over advanced and the system too lean is as a result of some hoses which are either worn or not properly fastened are leaking air especially the pipe that goes to the throttle mouth. In most cases, the MAF Air flow meter is also a suspect. Are the two clips holding the air flow meter fastened? Most people always tend to ignore that aspect. Try to check all your hoses. And also the oxygen sensors are aging and all you need to do is to change the o2 sensor bank 2. Also change the air filter if it is dirty.

is this thread still active?

Yes, very active

Does your Range Rover engine clatter on warm up? The engine oil that is being used is the culprit. Just look for the highest grade of Castrol edge and it will gradually go away

To whom it may concern...avoid these guys o. They sound knowledgeable (thanks to Google) but once they corner your car which is in good condition, before you get it back from a simple and routine fix you'll pay through your nose plus dig up your ancestors grave to appease the Gods you didn't listen to...

Hmmmmm

Sooperrescue, who you offend?

Na wa O!

Why should someone walk into your thread and drop such statement?

Na my very good customer that got fed up with his car not fixed at his own convenience

Octane ratings
Difference Engine: Who needs premium?
Sep 17th 2012, 10:19 BY N.V. | LOS ANGELES


EVEN at the cheapest petrol station in your correspondent's neighborhood, filling up the family kidmobile with premium (91 octane) fuel now costs over $70. As the meter clocks up dizzying dollar amounts, he looks longingly at the regular (87 octane) pump. Switching from his vehicle’s recommended premium-grade fuel to the cheaper variety would lower his fuel bill by at least 20 cents a gallon (more than five cents a litre). The question is, would it be worth it?

On the surface, the decision appears easy. Because the name “premium” implies a souped-up fuel that packs an extra punch, many motorists actually believe it delivers more oomph or miles per gallon—and may therefore represent good value. The truth, however, is that premium contains no more energy than regular petrol—around 114,000 British Thermal Units per gallon, depending on the season, the region, the local pollution requirements, and the amount of bio-ethanol that has to be added to petrol in America by law to keep the country’s corn-growers in clover (see “Competition at the pump”, August 20th 2012). The difference between premium and regular petrol lies in the blend of hydrocarbons used to make the fuel, and the package of additives mixed into it.

Nowadays, petrol is made up of hydrocarbons (mainly paraffins, naphthenes and olefins) produced in a catalytic cracker or reformer. The refinery process breaks the crude oil’s large hydrocarbon molecules into smaller ones by vaporising them in the presence of a powdered catalyst (an absorbent mineral such as zeolite). The blend varies depending on where the crude came from, the refinery equipment used, and the grade of petrol being produced.

Additives are included to reduce carbon build-up inside the engine, improve combustion, inhibit corrosion and allow easier starting in cold climates. Fuels that meet the requirements for “Top Tier Detergent Gasolines” (a voluntary standard endorsed by BMW, General Motors, Honda, Toyota and Volkswagen) contain more detergent in their additive packages than the minimum required by the authorities.

Another key additive that blenders stir into their brew is ethanol. That is done these days primarily to boost the fuel’s octane rating. A higher octane rating allows an engine to use a compression ratio of, say, 12-to-one instead of a more usual ten-to-one. The greater the compression, the higher the temperature within the combustion chamber. And the higher the temperature, the greater the thermal efficiency and power produced. In a nutshell, high-compression engines designed for performance need high-octane petrol.

Though ethanol has less energy per gallon than petrol, it has a considerably higher research octane number (RON)—around 108 to premium’s 97. It should be noted that this is not the octane rating seen on the pump in America. The RON figure results from a laboratory test done using a special engine with a variable compression ratio.

In the fuel test, the compression is raised until the engine begins to “knock”—ie, the fuel in the cylinder ceases to burn smoothly and instead detonates before it can be ignited by the spark plug. The cylinder pressure at which this occurs is then compared with that achieved while the engine is running on a reference fuel (a mixture of iso-octane and n-heptane). The ratio of the two pressures provides the RON of the fuel in question.

A better way of measuring a fuel’s ability to resist knocking under load is the so-called motor octane number (MON) test. This uses a similar test engine, but with a preheated fuel mixture, a higher engine speed and variable ignition timing. Because it uses more real-world conditions, the MON rating is typically eight to ten points lower than the equivalent RON figure.

In Europe, the octane rating on the pump is simply the RON figure. America, by contrast, uses the average of the RON and the MON figures, called the AKI (anti-knock index). Thus, 97 octane “super unleaded” in Britain is roughly equivalent to 91 octane premium in the United States.

Whatever the test, the point is that knocking needs to be avoided at all cost. If allowed to continue, it can quickly cause an engine to disintegrate. That is because when the air-fuel mixture in the cylinder detonates spontaneously before reaching the top of its compression stroke, the rising piston confronts a wall of rapidly expanding gases from the explosion, which attempt to force the piston back down the cylinder. The stresses caused by suddenly trying to reverse the rotation of the engine can become high enough to shatter the pistons, connecting rods and parts of the crankshaft.

To prevent that happening, a high-compression engine uses a blend of hydrocarbons that is somewhat less combustible than normal. Ethanol has an auto-ignition temperature of 362ºC, while petrol bursts into flames without a spark between 246ºC and 280ºC, depending on the blend. Therefore, adding a little ethanol to petrol can raise the auto-ignition temperature enough to prevent the blend from igniting purely from the heat generated during compression.

On the face of it, then, a motorist would seem ill-advised to use regular petrol in a car with a high-compression engine. That was certainly the case in the past. But cars today have sensors that listen carefully for the knocking sound, and instantly retard the ignition system when they detect that detonation is about to happen.

The delay in delivering the retarded spark allows the piston to start moving downward on its expansion stroke before the ignition actually occurs. That provides additional room in the cylinder head for the gases to expand and thereby reduce their damaging peak pressure—and so burn in a more controlled manner.

To sum up, if the car’s handbook says that premium petrol is “recommended” (rather than insisting it is “required”), then the engine will automatically adjust itself to run smoothly on a lower octane fuel. Because of the retarded ignition, the engine will, of course, produce less power, and have slightly higher fuel consumption. But the poorer fuel economy is likely to be outweighed by the savings at the pump.

Even so, your correspondent remains reluctant to make the switch. One reason is that no one has been able to tell him what damage is done, if any, by running the engine permanently in a retarded state, and forcing the anti-knock system to remain active all the time.

Another reason is because all the vehicle’s emissions testing was done using the recommended grade of fuel. Despite the fact that modern fuel-injection systems adjust the air-fuel mixture for changing conditions, your correspondent still has no idea how much more pollution the car might dump into the atmosphere if he switched to regular. Premium certainly has a better additive package, which helps keep the tailpipe clean as well as the inside of the engine.

But his biggest reason for sticking with premium, though, is that he was well aware that the car needed 91 octane to work properly when he bought it. And having paid upfront for the higher performance, he is reluctant now to throw that benefit away.

As for those who earnestly believe (and quite a few do) that filling the family Toyota with premium will somehow make it go faster or deliver more miles to the gallon, all one can say is don’t bother. As one wit noted, the only thing it will make run faster is money from your pocket.

Please what's the difference between land Rover and Range Rover.
And what's the cost price for a Range Rover autobiography 2016?

Land rover is the name of the parent company of range rover brand of suvs. They choose to keep the land rover name for the lr 3 and 4 and use the range rover for other vehicles based on the own decisions. I remember that my uncle owned a 1982 range rover in 1982 and it was a range rover while there was the defender called land rover which was used mostly by the military and the police. It's their company policy. Concerning the 2016 rr autobiography, let me have the specs you need. Colour, interior and many more before I can tell you the price

Bro I saw this Vogue online and its a 2010 model , it is used in Nigeria. What will be the pros and cons on this model and is it worth it? its going for about 6.5

I like the model but i want to know if this model can kill owner or if its something You can manage

Thanks waiting to hear from you

Hmmm, it will not kill the proud owner or else you wont buy it from someone. Just check the three components, engine, transmission and air suspension and also know the service history, the engine oil that they have been using, that oil is the major determinant as the engine is prone to failure due to the oil not being able to withstand the high temperature and bring it under control. If these three items are in order, take it and enjoy your ride.

Thanks Bro, its a diesel engine so i think i will pass on it as diesel is not advisable reading from your posts due to Nigeria diesel conditions

Ahh, Dieselllll!!! Pass vite vite. The high sulphur is an issue. A client of mine that uses a diesel car narrated how he has been able to survive the malaise. He will buy diesel in kegs and leave it in his house for 2 days and later will filter the sulphur from the diesel and then pour it into the car. It is a hard way to travel and I am sure you are not ready for that but that price is on the high side. I have sold a 2014 sport diesel for 9 m. There are also additives that you can use to reduce the wahala and it is very effective too.

Hello Range Rover Sports Members, your car is too valuable not to be insured. This is for you...

For many drivers, motor or auto insurance is more a pain than a benefit, with the pain partly being located in the high premiums they have to pay. But hey! There’s some good news; auto insurance protects you from personal liabilities should you be in an accident. What happens if you get hit by someone who doesn’t have insurance? If you do not have insurance either, chances are, that you will be faced with paying your own medical bills. Not cool! If you’re shown to be at fault in an accident, you may be required to pay for the repairs of the car that you hit. Fair enough, right? But not cool either, because this is money coming out from your pocket. Save yourself from uncertainties, from embarrassments, from unplanned expenditures…I bring to the table the good news about insuring your cars, buses, trucks with[b] ENSURE INSURANCE PLC.[/b]

Should you really be punished for having your car stolen or damaged?

Why should you be paid less than you insured for when a claim arises?

How quickly would you like to get back on the road after an accident?

How about a premium refund of 15% of 2years cumulative?

How about a 15% discount for all women and exclusively for men at 45 and above?

How about a replacement of your vehicle or the cash equivalent?


















That’s not all!

We will not penalize you for Depreciation. You will get paid the full value of your adjusted claim.

Should you get injured in an accident while in your car, we will assist you with the payment of hospital bills up to N500, 000, while the occupants in your car get a sum aggregate of N250, 000.

You need to know that:

We settle claims promptly;

You get 15% cash back on your premiums if you make no claims after 24 months;

Female drivers receive an additional 15% discount.
