  • Petrol for fun, diesel for job

  • You forgot to mention that it is easier to start a petrol in winter, that's why most Russian big trucks run on petrol, so they can start in winter in Siberia

  • The thing that really made me like diesels is that you can create diesel fuel from almost any oil, like vegetable oil, or even used cooking oil (as long as you properly filter out particulates). It does have to go through a refining process, but you could essentially make your own biodiesel with oil at home if you wanted. That's cool! You basically just need oil, methanol, and lye, and some know how, and you can make biodiesel that can run in modern diesel engines with no conversion necessary (except if you have natural rubber seals, biodiesel eats through them so you'll need synthetic seals).

  • Just think about, why Vin Diesel is not Vin Petrol... ;

  • When you learn more from a 4.5 minute video than an entire day at school

  • Our company has several cars with the same model and year but different engines. The petrol one consume 1 litre per 7 km. The diesel one can go about 10.5 km per litre. I like diesel more not only the fuel efficiency but also its got more power going uphill.

  • From an engineering standpoint, the diesel's are way better due to the higher thermal efficiency. Now if we could do a diesel cycle with gasoline rather than an Otto cycle... that would take the cake

  • You explained this video faster than a diesel engine compression. I got nothing

  • There was a significant improvement in diesel's performances when commonrail system was introduced so they are now providing extra power and fuel economy as well as fully optimised work. There is a nice statement which says: where diesel stops, the petrol continues (regarding to high revs performances).

  • Hands down the best explanation of not only petrol/diesel differences, but also of the strokes in a 4-stroke engine. So concise and simply presented. Well done, guys!

  • If this world starts going for electric cars, which it is doing, then in about 50 years, history teachers in school will use this video to show kids what it was like in the petrol/ diesel era

  • Forgot one fact! Diesels can turn into "runaway diesels" where the engine revs uncontrollably up to even 14000 rpm because of faulty gaskets in the turbo feeds oil into the engine causing ignition, turning the key won't help because the engine runs on oil now and not on diesel, so the only way to stop a runaway diesel is to either starve the engine of oxygen by taking a wood 2x4 covered with duct tape and putting it on the intake manifold so there is no air entering the engine or by holding down the clutch and brake pedals putting the car into the highest gear available and dropping the clutch and pressing the brake pedal hard so the engine stalls. Anyway hope you never get to experience a runaway diesel this has been education time with Vault-Tec Representative goodbye

  • Such a cool video! I'm wondering if diesel would work in a rotary engine considering that latter's high compression ratio? I think Diesel would definitely help with the fuel efficiency and torque issues that rotary engines have.

  • One should point out that, although some newer diesels do have a throttle body/valve, it's not actually required for engine operation. Vehicles that do have it use it for allowing efficient EGR operation, smoother engine shutdown and sometimes help with engine braking.

  • AMAZING. Held back on learning about automobiles most of my life bc the mechanics I knew were too grumpy to explain. You, sir, made it easy to digest!

  • I own both a Turbocharged Petrol (2005 1.5T Mitsubishi Colt CZT) and a Turbocharged Diesel (2016 Seat Leon FR 184 TDI with a DTUK Tuning Box) car. Personally, I prefer the Diesel, boost kicks in way sooner (1800 RPM in the diesel, around 3500 in the Petrol) so it's great for overtaking and just in general driving such as pulling away from Junction. However I always make sure to only use the Diesel for longer journeys and the Petrol for shorter journeys to shops and such as the DPF getting clogged can be a big problem with the Diesel if you're not driving it often and long enough.

  • I'm a fan of both the engines. 🙂

  • This was actually very helpful especially with the compression ratios, I was wondering about that
