Mine is E320 V6 12plugs,but my tank s much smaller,I had filled it from reserve light on with less than 5k.the tank is even much smaller than that of my W124 i4.I filled that with 7k5.
I think the V6 tank is smaller as the fuel economy is great

But you seeing 80ltrs to read 11,500 means u are not buying at the normal pump price,80ltrs on normal pump price is less than 7k.


I think all cars that comes with a dual exhaust pipe tend to have smaller tanks cos the tank has to be centered and far enough from the manifold. Mine has dual manifold from the engine but my exhaust is single and placed at the rear left.

Usually I'd fill my tank with 6k-7k depending on the meter but I was buying at 180/ltr with a really bad meter but WWJD! undecided

bro abeg in case of next time, there is nothing like v4 OK. its only i4 which means inline-4. it means all the cylinders are arranged in a straight line then you also have i6 or v6. i6 have all their 6 cylinders in a straight line while v6 have 6 cylinders with 3 on one side and another three on the opposite side. the connecting rod of each piston opposite each other is connected to a single crankshaft forming a 'v-shape' hence the v6. so abeg stop saying v4 as it sounds so rritating. it's like u hearing someone say INEC is international Nigeria electoral commission. its disgusting init?

sorry o, at least u knew i was referring to 4 cylinder engines.

Not strictly true sir.

You might be getting things mixed up. The exhaust manifolds are st the front of the car, on the cylinder head/s. Nowhere near where a fuel tank will be mounted. Fuel tanks are mounted at the rear, in front of the rear axle, though some older models had then mounted behind the axle (deemed dangerous by modern standards).

The fuel tank does not have to be mounted centrally, and very seldom are. They are not regular shaped, and are shaped according to the exhaust route, rear axle and differential on RWD / AWD vehicles. Fuel tanks are generally offset as a result.

Dual rear exhaust and mufflers do not necessarily mean a smaller tank, as the tank will be shaped around whatever components are underneath the car.

Examples are the Audi A4 B6 1.8T. Available with single or dual rear mufflers, Quattro or FWD, the fuel tank remains the same capacity at 70 litres, same as the 3.0 V6, which only comes with dual mufflers. The only difference is the tank shape.

please correct me if I am wrong but isn't that a 2.0 litre v6 engine? if so then its economical as it has similar engine volume as most i4s. it will develop more power than the equivalent i4 and therefore will give better economy.
when I talk about v6 I usually refer to engine capacities of 3.0 litres and above.
nice car bro.

It's a 3.2 I6.

V6 even consumes more fuel than 4 plug but people don t know that,me as a person can never buy 4plugs vehicles,I hav been using my camry v6 for over 4 years now and no issues,I travels to my villa in the east with full thanks and still uses my car for some day before buying fuel,I think people that talks bad about v6 are mostly people who hav nt even used the car,ask the people that uses v6 cars and they will tell you v6 engines are the best,

In addition to what siena has said, by default every car owner should cross-check between two cars their MPG(miles per gallon)......
If you see an online review of a I4 car that uses 22mpg and a v6 uses 21mpg...Technically, it means that I4 will consume more fuel. So its important for car-users to know how much kilometres/metres they can go with "so-so" amount of petrol. So when the figures (mpg) starts going higher, you'll know something is wrong....here is a pic extract
So what do u have to say about this?
Same car, one with v6 and other with i4.

4th column is users average mpg.

Ummmm, no. You're getting things mixed up here.

MPG is NOT a used value, it's a return. In your example, I4-engined car returns 22 mpg (travels 22 miles for every gallon of fuel) while the V6-engined car returns 21 mpg (travels 21 miles for every gallon of fuel).

Distance travelled per gallons of fuel used, the I4-engined car is consuming less fuel.

DOHC is double over head cam, which means at the top of the cylinder, there are two camshaft. 40V means 40 valve, which means each cylinder carries 5 valves since its 8 cylinder. some have 3 inlet valves per cylinder and two exhaust (outlet) valve. SOHC is single over head cam.

Thank you for correcting me, but it still bores down to the same thing that mpg is a determinant for identifying by default which car is petrol hungry.

From your pic, by default the 4cylinder toyota solara is more fuel effecient. Based on the 4th grade which is the consumer reviews, it could be higher than the "default stats" because of certain factors ; like clogged fuel filter, tyre pressure or even driving style. This was why I said "techncially" if we compared two cars by their mpg we should tell which is more fuel effecient. But then there are factors to be met, maybe those factors weren't met and that's why its a lil higher than the "default stats"

I thought higher mpg means a more efficient engine. How come a clogged air filter is making an engine more efficient?

If I understand simple logic, the higher user mpg simply means dt users are seeing better fuel efficiency than what was actually stated in d books.
Comparing d user mpg of the i4 with d v6, I noticed it is almost d same. This means dt users of d v6 get almost d same fuel efficiencyfrom their v6 engine as users of d i4 engine.
If d above lay man deductions are correct, then d v6 engine is actually d better engine to buy.

Plz Siena and Gazzuzz, confirm or discredit my deductions.

Lool, sorry bro. I'm mixing things up......a higher mpg means a more fuel effecient car, from your picture. the i4 is still more effecient from customers review.....although the difference is minimal. 30.6mpg (i4) against 30.0 mpg (v6). Not much of a difference. With that very lil difference, I believe the v6 will be more attractive. Sorry for my previous comment. I'm reading double tonite coz of my "football teams loss"........what I was trying to point out in my previous comment which is completely not in line with the debate, is that. If a car owner acheives lower mpg than the stated mpg by the maufacturer. It could be as a result of some factors, like the clogged filter ,driving style etc
But from ur pic, the mpg are higher than the default figures from the car makers, that I cannot tell how possible it was acheived

My last car was a 4cyl and it was REALLY BORING. I never owned a v6 but I knew something wasn't right. I confirmed it when I drove a friend's Avalon. My! I instantly realised I've been riding a bicycle.
On another occasion, I raced a mechanic friend who is not even a crazy driver like me. He was driving a VERY OLD v6 Camry. Something from d 80s. I had my 4cyl 2001 accord. The race was from push off. I nearly broke my engine dt day. No matter how I throttled, it was as if my car wasn't moving. The rickety old car embarrassed my fancy new car.

It's a common misconception that a V6 engine will use more fuel than an I4.

Fuel consumption is determined by:

Engine capacity.
Internal friction.
Emission level.
Vehicle weight.
Transmission type.

The most determining factor is the engine capacity. This is is the actual swept volume of the engine, the cylinder bores the pistons operate in. It stands to reason the larger the capacity, the more fuel is required to feed it. Sometimes though, the engine is designed to run lean (lean-burn technology) and so a 2.2L engine MAY use LESS fuel than a 1.8L version with standard fuel injection. Design is key.

Internal friction will also affect fuel mileage. This is where there is more resistance to rotation and piston movement. More resistance will require x amount more of fuel.

Emission levels are becoming increasingly stringent. We're currently on Euro 5, though 6 is just being introduced. The lower the emission level number, the more fuel the engine will use.

The myths that a V6 engine will use more fuel than an I4 are just that - myths. The main assumption here is that a V6 engine has a larger capacity than an I4. This is not always the case.

A Mazda 1.8 comes as a V6 in the '97 gMazda 323F. It WILL use LESS fuel than a 2.2 I4 in the '98 Toyota Camry. Euro 2 Vs Euro 2.
A Porsche 3.0 comes as an I4 in the '91 Porsche 944 S2. It WILL use MORE fuel than a 3.2 V6 FSI in a 2006 Audi A4. Euro 3 Vs Euro 5.
A Jeep 4.0 comes as an I6 in the '99 Wrangler. It WILL use MORE fuel than a 3.7 V8 40V in a 1999 Audi A8 Quattro. Euro 3 Vs Euro 3.

The above are just 3 out of millions of variables. I will cite another example to do with weight.

A '91 E34 BMW 518i (1.8L I4) WILL use MORE fuel than a '91 E34 BMW 520i (2.0 I6). Both Euro 3, but the smaller 1.8 4 cylinder in a relatively heavy car will be working harder, and require MORE fuel as a result. The bigger 2.0 6 cylinder will have an easier time, and require LESS fuel. This is one of the reasons BMW dropped the 1.8 engine for the 1992 model year in the E39. For those who allow their mechanics to yank out their engines in favour of a smaller version, take note!

Transmission type will also determine how much 2 similar engines will use fuel.
I disagree with this parmutation. Euro classification is based on CO2 emission and CO2 emission is not proportional to mpg especially when comparing old engine with newer engine with a lot of improved technology to reduce emission. in nutshell that two engine has different; Euro 4 can be more efficient than Euro 5 but the clasiffication show Euro 5 has lower co2 emission. And lets not forget that in latest engine devolopment, there a lot of l4 turbo that has power of v6 with efficiency of l4 likewise v6 and v8. and most importantly effient also depend on engine manufacturer.

V6 are generally bound to consume more fuel than l4. the fuel effiennt difference becomes reduce significantly if you usual travel long distance and also like high speed and racing that is when it is hard to notice. but v6 becomes pain in around town, in traffic and if you are conservative driver. l4 efficeient is still noticeable in long journey if you allow the rev to remain in sweet spot and avoid chasing cars.

True, to a certain extent. To be clear here, cruising is the art of accelerating up to a decent speed, then backing off slightly, allowing the engine to run on a part-open throttle. This is where any engine is most economical - providing the engine produces enough torque to maintain useful vehicle motion.

However, with an under-powered I4 engine, it is harder to maintain that sweet spot (approximately 2800-3200 rpm @ 70 mph). A naturally-aspirated I4 up to 2.0 litres with a modern 16V cylinder head is peaky, meaning it makes good power, but further up the rev range. This means the gearbox will be geared lower to make use of the high-revving characteristics inherent in naturally-aspirated multivalve engines.

Between 2800 and 3200 rpm, such an engine will not make bags of torque to sustain a constant road speed, without pushing the pedal harder every now and again. A turbocharged 4 will be happy here. So will a larger-capacity V6, boosted or naturally-aspirated. I have done long-distance trip, mostly driving on the Continent, with 4 passengers and luggage. I have found 4 cylinder engines to be thirstier on these trips. The smallest engined-car I drove from Central London through Calais, France ending up in Brittany, Northern France was a 2003 Renault Clio 1.4 16V manual. The car was 10 months old then, it averaged 44 mpg over 633 miles. My 2005 Audi A8 Quattro 4.2 V8 with a 6-speed Tiptronic transmission did the same trip, and averaged 32.7 mpg over 629 miles. It was much easier to maintain the sweet spot with the bigger car, and the engine was more relaxed.

Of course, a boosted I4 may make the same power as a V6 or V8. It will have better gas mileage around town, where it may be easier to drive the car, keeping the turbo off boost. It is not easy to stay off boost at highway speeds, and when boost cuts in, ignition timing is retardéd, more fuel is injected, conditions where every boosted engine will give poorer gas mileage. This is true of every boosted gasoline engine.

Every manufacturer is striving to produce the most efficient engines, so that is a subject that will run into 100's of pages here. Lean-Burn tech, Cylinder Dectivation on V6 / V8 / V10 engines, Atkinson Cycle engines, V-Tech, VANOS, VVT, VVT-I VVT-LI etc. There are tons of variables.

When comparing an I4 to a V6 engine, we're looking at engines from the same manufacturer, in the same model of car. As you stated, efficiency can depend on engine manufacturer. So comparing a 2.0 I4 DOHC 16V gasoline engine built by Honda and similar built by Toyota will produce different results, despite having the same capacity, and both being 2015 engines.

The Emission Standards does affect how power is produced in any engine, and what mpg can be returned. Whilst not directly proportional to consumption, ES is a trade off between economy and performance. It is virtually impossible to have both in all driving conditions.

The smaller engined clio return better mpg which is the crux o the matter. We all accept v6 and bigger engines are more fun to drive but you fill up more than someone who drives an i4.

You are correct but there is something I want you to know what I mean by sweet spot. I mean very very flexible speed even below 60mph when climbing hill, just making sure the the engine is not working hard as it should. That is why I said v6 is best for power and speed minded individual because such person will end up working l4 harder thereby Making fuel economy even worse than v6 because v6 wouldn't need to be worked hard but if a person is economy minded like high miler like me, he will be able to speed to high speed at appropriate time like down hills and able to keep in engine always in best optimum operations even if it takes dropping speed to 40mph up hills. this also mean cruise control is not good for a good high miler, I said good high miler.

The more u guys argue, the more I see reasons to stay away from i4 and embrace v6. The bold line just describes me. I just had to back off a deal I had for a 2nd gen i4 solara. Going for v6 of same ride instead.

Maintainance is d key. Air filter, spark plugs, injectors, engine oil, oxygen sensors, knock sensors, etc.
My i4 babyboy had an economy worse than a v8 when I got it from a friend. By d time I was done with it, it came back to life. That little thing with wires on ur exhaust manifold is really important. But ur kazeem doesn't know it.

yes v6 is better, you only feel the difference in economy much around town and city traffic. But again there are ppl that is very obssesive of fuel economy like me, hybrid is in my mind, that extra liters in fill up just make me unhappy because i dont care about speed or power, all i care about is smooth economical car.
