Used VS New Oil in your Car | Fifth Gear Classic

In this classic Fifth Gear clip, first broadcast in 2014, Vicki shows why it's so important to change the oil in your car.

So Gran Turismo 1 wasn't lying about getting more power from oil changes. Interesting.

[traceurGeorge]

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!

That R32 looks beautiful there! They don't make them like this any more.

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 :-/

I am tempted to believe that what made the difference was : 1. Different atmospheric conditions, lower humidity and different temperature/pressure; 2. Clean air 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.

[jmarchant]

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.

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.

The oil sample results/wear metals were really good especially for 10k miles.

[guusbouwmans]

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.

[danc]

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.

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....

[steveguest]

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.

The engine will be quieter and smoother

[NickHazletonMusic]

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

[synthwave]

used oil contains 2, 5% petrol" - wow - that is surprising high for 10, 000 miles. Nice video.

[Slaktrax]

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

[Inazuma]

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??

[mackcummy]

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

[avir]

These golf r32s are gorgeous in that colour and those wheels. If only they where as reliable as my type r I'd buy one if I could find one in good shape.

it is shocked!😮
what is the cause of the bug inside the engine!!
