- * VISUALLY EXPLAINED
Multigrade engine oil's ability to function effectively in a wide range of temperatures is a result of carefully selected and engineered ingredients. These ingredients work in combination to ensure the oil performs well in both cold and hot operating conditions. Here's a breakdown of the key ingredients and how they contribute to the functionality of multigrade engine oil:
Base Oils: The base oil, often derived from crude oil, forms the foundation of the lubricant. It provides the oil's primary lubricating properties and serves as a carrier for additives. Different types of base oils, such as mineral oils, synthetic oils, or semi-synthetic oils, can be used to create multigrade oils.
Viscosity Index Improvers (VII): These are polymer additives that play a critical role in making multigrade oils versatile. At low temperatures, the VII molecules are coiled up, allowing the oil to flow more easily (lower viscosity). At high temperatures, they expand and uncoil, thickening the oil to prevent it from becoming too thin (higher viscosity). VII additives are essential for achieving the oil's multigrade properties.
Detergents and Dispersants: These additives help keep the engine clean by preventing the buildup of deposits and sludge. Detergents remove existing deposits, while dispersants keep contaminants suspended in the oil, preventing them from settling on engine components.
Anti-Wear Additives: Anti-wear additives form a protective layer on metal surfaces, reducing friction and wear. They are particularly crucial in high-stress areas within the engine.
Friction Modifiers: These additives are used to enhance fuel efficiency by reducing friction between moving engine parts, especially in areas like the piston rings and cylinder walls.
Anti-Oxidants: Oxidation can break down oil and create harmful byproducts. Anti-oxidants are included to slow down this process, extending the oil's service life.
Corrosion Inhibitors: Corrosion inhibitors protect engine components from rust and corrosion, particularly in areas where moisture can accumulate, such as during cold starts.
Pour Point Depressants: These additives improve the oil's low-temperature flow properties, preventing it from thickening or gelling in cold conditions.
Anti-Foaming Agents: These additives help reduce foam formation within the oil, which can hinder lubrication and lead to inadequate protection.
Seal Swellers: They are used to rejuvenate and expand seals and gaskets in older engines, helping reduce oil leaks and maintain the oil's viscosity.
Coloring and Scent Additives: These are added for product identification and consumer appeal, but they don't significantly impact the oil's performance.
These ingredients, in the right proportions and formulations, work together to create multigrade engine oil that can offer consistent and effective lubrication across a wide range of temperatures and operating conditions. The specific formulation and balance of these additives can vary among different brands and types of multigrade oils to meet the performance requirements of various engine designs and applications.

Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍
The best explanation on engine oil. No one has ever tried to simplify the oil mystery before.
Thank you so much for the nice feedback. I really appreciate it. Craig
I wanted to add: Great Video, don't you wish School was like that when you were growing up? Good teacher, good visuals, concepts in logical sequence. No Brats to disrupt your learning, and no Damned Test. CZcams is Awesome.
William Pietschman - test-If you are changing oil in a Toyota Highlander on a Wednesday in a leap year would you use - 10W-30, SAE30, 0W-30 or 3 in 1?
For a year, I watched almost a hundred videos on CZcams about oil viscosity and this is the only one that really explained it to me; thank you for your time and efforts
LOL, not real quick on the uptake?
One of the best explanations of oil on the internet. Thank you for creating this.
I think it's one of the best explanations on the Internet.
Craig, if all educators were like you, the world will be so much better. Not often I discover someone teach so eloquently and concisely. You really demystified this topic. The simplified chemistry near the end helped me finally understand how engine oil gets thicker when hotter instead of thinner. Bravo! Thank you!
You really demystified this topic.
That's what it's all about, I feel - demystifying the topic.
One of the best informative video I have ever seen. It helps me to overcome my confusion about engine oil grade.
Finally I understand what the numbers and the letter means. Thank you 👍
Superb explanation, really appreciated. The only video I came across on CZcams that explains oil behaviour in so much detail and so logically correct. Really appreciated.
i have not found a video in youtube that has a better discription an esplanation and breakdown that this video. all other videos are short quick tips that dont really mean all that much. But this video is so details and well structured. i now feel a lot more clued up and have a much better understanding and better grasp of what is happening and what to look out for in hte oil viscocity ranges. like i never new the viscocity range , ranges from 0 to 60 and no other video lists this. thank you for this well put tegother video
Thank you for your kind feedback. 👍👍👍
Fantastic rendetition!
Out of hundreds of people simply babbling along just trying to explain oil weights you sir have made it very clear and easy to understand to what id like to think for anyone.
Not only did you simplify and explain but you shed light on the deeper inner workings of the oil which is something ive always desired to know. Thank you sir very much.
I think I am finally beginning to understand this mysterious process. Great explanation!
If I am a mechanic instructor, I would just play this video in class while marking paper. Very educational. Thanks
Absolutely bloody outstanding - Thank you for a very clear and easy to understand explanation.
I'll put Mobil 1 esp 0W - 40 in everything
At least I now know why I'm paying more money !
This is an excellent presentation! Thank you for explaining how oil structure changes with heat, modifiers and solvent.
I viewed many videos on engine oil and now I finally understood how it work after seeing your video. Thank you very much.
Thanks very much for this and the last video Craig, I imagine it will have taken a while to produce them and they will be of help to me and I imagine others for a very long time. Nice to find someone new I want to subscribe to as well

Thank you so much, after 41y i now finally know what and how oil is and works in the car! you should have a pay pal for donations!
Best explanation on CZcams!
Wow that's an amazing explanation, now everything makes sense.
Very helpful. Love the molecular explaination as well.
Excellent message. Thanks a lot for the great explanation provided technically
Excellent job of explaining how it all works together. Maybe you could take one more step of how the different oils work themselves. The modern oils have changed a lot from the early days to cover different types of engines and requirements. Thank you.
Such a good video. It deserves a subscribe
It was a really really great video for me. It explains all complex parameters very simply. Thanks alot
You are welcome! Than you also.
Very best video..now i know..thanks a lot in million times for this technical info

Amazing explanation. It would be great if many of the other CZcamsrs would learn from you.
great content and we learn something new from this video.
im pleased it was useful :D
-Craig
really informative and even easy to understand . Thanks .. !!
Thanks very much from Japan.
(That is to say one bloke in Japan and not the whole nation :) )
That is a top class video.
Appropriately simple and comprehensive in every part, nicely paced, nicely ordered, great graphics.
I'd give you an award for it... if I were able.
Now I know what it means that my bikes' manufacturers demand the use of such specific oils. In 1990 I was, very briefly, an apprentice mechanic at a Toyota dealer in the UK. I was not there long enough to learn this - bad relationship with the dealer manager.
I feel I have gone up one grade from, say, level 20/100 to level 21/100.
Thank you for your feedback. I really appreciate it. Craig
Really great explaination! thank you :)

Learned a lot frm that bro thank you good video
👌 awesome explanation.
I love the diagram explanation very well informed
you might have gotten me my job at TOTAL thanks so much my man
Great explanation.
Excellent explanation
5:50 that's why some older engines like my pickup truck have main bearing knocks on Startup and then after they get oil pressure they stop. It's also weird we live in a time where warm oil gets thicker and cold oil gets thinner completely opposite of what it should be great video man
Thank you so much for the nice feedback. I really appreciate it. Craig
Thanks for the explanation! You saved my day. Gracias
Glad it could help you :D Thank you for your kindness :)
