I always felt, top gear was fun to watch, taught me about the cars on the road - most of which I wouldn't ever see or ever be able to own. Fifth gear, was more interesting and taught me how my car works and how cars in general perform. Both great programmes!

Yep, thanks god they don´t make 3.0 VR6 engines with only 200hp and 15 liters/100km. We evolved.

[@Can-Am1989]

I am tempted to believe that what made the difference was : 1. Different atmospheric conditions, lower humidity and different temperature/pressure; 2. Clean air filter.....(maybe even different fuel). This test should have been done with clean air filter with both oils in a controlled dyno chamber, same temp and humidity and same fuel.

[@andrejflis8161]

Not to mention it is a manual... Good luck geting every shift off with the same time. A DSG would have much more even shift times, making it a much better comparison.

[@leafysfishing]

Exactly.. half a second difference 😂 and put down to a oil change, over everything else (including weather conditions) is a very big conclusion to make.

[@aceman0000099]

And I bet she had shit and pissed in between so lower weight yeah?? Maybe wiped a few grams of mud off of her shoes?

[@Big1_]

Stop being a pathetic exceptical, new oil means new fresh aditives= Less friction in the internals= more power. Simply as that. Read it again if you did not understand something.

[@stephandolby]

There's a clue in the service interval - for example, 12,500 miles or 12 months, _whichever happens first_ . If you drive only 3,000 miles in a 12 month period, or drive 12,500 miles in only a 4 month period, it's time to change the oil. If you make frequent short trips that don't get the engine to optimum temperature, cut the interval in half. I have a DV6 engine and there's *no way* I'm leaving it for fear of killing the turbo, if rumours are to be believed.

[@xjet]

Lower viscosity in and of itself does not mean less lubrication. Modern oils are often 0W30 (very low viscosity) yet they provide *more* lubrication than the older 30W50 types which have a far greater viscosity. Lubricity and viscosity do not go hand in hand. I thought an informed automotive "expert" would have known that :-/

[@John2751]

I believe what you're saying is not the case here. The old engine oil you mentioned is mineral oil and fundamentally different from a modern synthetic oil. They're comparing a new and used oil with the same molecular properties, so there's a correlation between loss of viscosity and lubrication.

[@xjet]

@@John2751 Not correct. I've been using 15W50 synthetic motor oil for a couple of decades now. Viscosity does not equal lubricity. Film-strength is a far more important factor in lubricity and film strength is also does not have a direct correlation with viscosity. Oil is far more complex than most people are aware.

[@DashCamSerbia]

@@xjet Yes, but you have to use the viscosity that your engine is designed for.

[@motomehanicar459]

You didn't understand - losing viscosity means that oil got contaminated and oxidated so its flow is reduced. Over time 10w40 oil flows like 15w40 (oil is not getting thinner but rather denser because of the contaminants in it).

[@panzerveps]

@@motomehanicar459 Except that one of the contaminants is petrol, which thins out the oil. He is right though. 15% decrease in viscosity does not equal 15% decrease in lubrication.

[@jmarchant9155]

New oil, fuel and air filters will make more of a difference (if any at all) than the oil itself. Especially on a petrol as many people forget about some petrols having fuel filters.

[@tredfxman]

Cool Thanks! I will remember this for the GTI Clubsport MK7 seen on my channel! 👍 Maby it dont have a fuel filter though?

Well I have had two Corollas over the last 30 years and both only got serviced every 4 years I drive 8000 mile a year and I never had a problem, always used Mobil oil to the right spec both cars were amazing. The one I have now is an 06 so had it 15 years.

[@guusbouwmans5667]

Most oil pumps are driven straight from the crankshaft. The thicker the oil, the more resistance it has. Resistance on the crankshaft causes loss of power. Look at the difference between ac on and ac off 0-100 times.

[@Slaktrax]

The key to keeping the engine in tip top condition is to change the oil every 3 to 5,000 miles.

[@danc2014]

The big change in old oil vs new oil is the usable viscosity. The viscosity went down because of the non lubrication materials of water and fuel. These do not lubricate well , think what happens when you add a cup of water to the oil? But I believe the main improvement in HP and time was due to better seal in the combustion cylinders rings and thus more HP per revolution.

[@olanordtug1707]

My old Peugeot 405 diesel had 65 horsepower. Driving up a steep hill you did not need a watch to measure the time, you could feel it and hear it. On this car I changed the oil at around 5000 km. It was no old oil but still you could feel it....

[@aceman0000099]

That's almost as bad as the original fiat 500s

[@aaronrigg5208]

[@aIbercik]

R32 mk IV, the best VW they ever made

[@mdf113]

It would be interesting to know what the old oil was that came out, relative to the new oil that went in. I don't mean brand, I mean chemical composition....additives, detergents, base oil etc. A simple analogy her is.....would a sprinter set a faster 100M time in pair of "Nike Air Max Plus III" trainers or a pair of old worn out Tesco hobnail boots.

[@NickelArcade123]

That’s all well and good but I’m interested in that 4 door mk4 r32!

[@davidking1087]

Ah Vicky. The perfect woman...

[@MONK-7]

Wow a beetle in a VW. Class😁👍

[@Tom-lu4gi]

As the old oil circulates through the engine collecting microscopic particles as it sits between the gudgeon pin the big end bearings and the mains I can well believe it causes more friction thus resulting in a decrease in the optimum efficiency of the engine. Albeit minimal.

[@buggerlugz6753]

I so wish someone would do a "Nigella talks dirty" but with Vicki........ :)

[@manofweed1]

Nothing puts fear into the hearts of motorists like the subject of oil. Just the way the oil companies like it !

[@mackcummy4976]

I use synthetic in my RSX-S. Just changed it.

[@JamieR1988]

The other thing is tyres. It boggles my mind to see people drive on either balded tyres or no brand ones. It's literally the only part of your car that touches the road. Putting decent tyres on will drastically change the way your car holds the road. You'll get much better MPG and it'll be far far safer.

[@gravemind6536]

I agree but the MPG on tyres that grip the road better will not be better in fuel economy as there is more friction. However I have driven on cheap no name tyres on my first car and good tyres on my 2nd car and its eye opening the difference in grip is insane and anyone who drives outside of the city I recomend gets at least medium budget tyres. I think everyone should do some driving on cheap tyres and then use premium just so they understand how big the difference is.

[@niacal4nia]

Lower viscosity less stress on engine and better fuel consumption so how did it go faster with new oil?

[@kristianspencer1978]

Vicky is fit. And the r32 is nice too, 3 door nicer looking.

[@damianrobins6659]

The car also weighed a little less on the later runs due to less fuel in the tank... 😂 Needed to weigh the car, with driver (no offence Vicki), prior to each run. 👀

Every 10,000 miles imo is too long to wait for an oil change

[@gaffnaldo1]

I'm sure 5k is better. But engine designers now know exactly what oil to use even before putting pen to paper. 10k miles is fine according to most manufacturers. 5k can do no harm.

[@Vikturus22]

its waaaaaay too long. In modern cars they say 10k miles is ok I wouldnt believe it. I change my oil always at 6k miles, Ive done it on cars 20 years old and cars 5 years old. Always change every 6k miles ( if its under warranty and it blows engine due to poor servicing and it was done every 10k miles then its on them lol )

[@gaffnaldo1]

@@Vikturus22 clean oil always better than used oil. But did you see the million mile Toyota Hilux? Gets an oil change every 10k, always has right up to the 1 million. Still runs sweet. For me, this ends the argument. My own diesel jaguar runs at 20k miles servicing and there are no reports of blown engines or dry turbo's. Modern oils are engineered to perform like this and last longer

[@Tom55data]

@@Vikturus22 It is down to the quality of oil and expectations and the control of the oil industry. In Europe nearly everyone uses full-synthetic oil as it is much more consistent and contains less shit where as in the US there is even a believe the synthetic oil is bad. The US has this 3k rule for changing oil, of course, the US is the lobby place of the world where the corporations want you to spend more on oil and it is common belief this is required. Most modern cars actually check properties of the oil, and I have only changed oil at 10K intervals over 30 years of owning cars and keep them till 10 years old after buying 3-4 year old cars and NEVER had an engine issue with my cars. Also use an independent garage that I trust and actually does the work required only when required - and actually changes the oil.

[@gaffnaldo1]

@@Tom55data excellent reply. This probably explains the huge difference in opinion between Europe and the US when it comes to oil changes. Ive never seen a worm out engine before unless oil chnages were not being done at all. Engines that follow recommended servicing dont suffer wear issues

[@Inazuma68]

Wow that difference was surprising. As I am driving only on weekends, I am only doing 5000 km per year. So my oil is not used much. When I leave it for 2 years in the engine, is that a problem because of aging??

[@resnonverba137]

Yes.

[@rickyschodl7763]

change it every year at least

[@DashCamSerbia]

No. If you don't drive much, you need to change the oil sooner. Twice a year, or once a year at least. Because if you oil just sits there, it absorbs moisture, it oxidises. If you do short runs, it is very bad for the oil. When the engine is cold, the air-fuel mixure is ritcher and it delutes the oil. Oil is getting contaminated with hydrocarbons and water. Only when engine reaches operating temperature, those impureties start to burn off and evaporate of the oil. If your engine only reaches operating temperature basically when you arrive to your destination, know that your oil is in a very bad condition, and needs to be changed a lot sooner.

[@hkonhelgesen]

Modern high quality oil last 2 years. Cheap mineral oil don't.

Oil changes far more important on usage then actual time. Oil quality has moved on considerably in last 20 yrs. don’t bother changing every 6 months (scam). Oil won’t degrade that quick just in the sump. It’s mainly all about usage ( unless you don’t do any real miles). So highway miles engine isn’t working as hard as lots of short trips around town. At the end of the day, if you aren’t keeping the car for life, go with manufactures oil change on mileage but if you are keeping long term half the oil change interval. It’s cheap insurance overall

[@gravemind6536]

Given that my car does 90% motorway miles and probably 5% city and 5% rural I though keeping to the manufactures guidlines was more than good enough. If I did low mileage I would just change it ever year since it won't hit the mileage for an oil change.

Isn't a lower viscosity oil more efficient? 0-30 offers less resistance to the motion of the engine vs 10w30.

[@squadmeta]

The lower number refers to cold oil, but I get your point. I think the lubricity of old oil is worse, the viscosity isn’t the relevant factor.

[@hkonhelgesen]

The oil has to be thick enough to lubricate properly and seal properly. It also has to be thin enough to cool properly and clean properly. This car wants 5W-30 oil. VW 504.00 quality should last 2 years or 30.000 km (20.000 miles).

[@gravemind6536]

Engines do fail usually because of head gasket failure. A well serviced vehicle however the engine should never fail. The clutch will burn out eventually but 5 or 6 clutche replacements is cheaper than a failed auto gear box. I have seen personally clutches last of 250k miles. City clutches obviously burn out quicker. With most cars though I agree its other things that fail and cost more than the cars worth that eventually kill it off.

No wonder people think 100k miles is high mileage when the average person is only changing oil every 10k.... Oil and filter should be done every 3-5k if you want the car to last.

I hope this video wasn't financed by the oil companies. With additives now adays (especially in synthetic oil) you can go at least 10,000 miles before changing it. Now, that is in normal driving. Also, our systems are so sealed, little or no water gets in. Those "dangerous" particles that gets into the oil are usually picked up by our oil filters.

[@2ndProtects1st]

Peter Norman that’s why new bmw are braking down.

[@JakobusVdL]

Normally the car manufacturer specifies the service interval. Oil change intervals have increased substantially over the last few decades, due to better oils, better manufacturing of engines, better filters, probably lots of other reasons too. Intervals of less than 6000 miles/10,000km were common 20 years ago - even for BMW's.

[@darjluke]

If half the cars don't have enough oil, how many have never changed oil? Kinda makes me think this is a warning about buying used cars. Seller may show a book with regular maintenance done, but anyone can just rubber stamp that book. Many people get a oil change and then put the car up for sale. If you look at the dipstick, it looks like light tan. No mechanic is going to disassemble the engine to find the sludge. Just get a sample on the dipstick and analyze it.
