Thanks for your informative videos. I'm glad to see you that you're getting more subscribers. I particularly appreciate your explanations of oil types and oil additive functions and chemistry - my high school chemistry and physics teacher left a lot to be desired and you do a great job of explaining without over-simplifying. Maybe it's not in your area of expertise, but I'd love a Gasoline Explained channel or playlist to explain the formulations and additives of modern motor gasoline and dispel a lot of the internet fallacies and myths on that subject.

[@LubricationExplained]

Thanks! Appreciate the feedback - personally come from a mechanical engineering background so this is the way that we would explain chemistry to anyone that's more mechanically-minded. As for "Gasoline Explained" - that's a great idea. At the moment I'll share the "Engine Oils" playlist with you: kzbin.info/aero/PLu1i0eyydBX2L4q2Uk4rBh07n7b_YuU3x but your idea to have a "mythbusters" segment is a really good one. Are there any particular "myths" that you would like to see addressed?

@@LubricationExplained 1.How fast it takes gasoline to break down, particularly to the points that it can cause gum and varnish and where it ceases to provide adequate power or effective ignition? I realize there's a lot of variables, but I love to hear about variables and how they affect things. 2. What is the chemistry behind gum, varnish and sludge formation in gasoline? How do gum, varnish and sludge differ or relate to each other? Does ethanol and additives make it form faster or to a greater extent? How does it chemically interact with the different fuel and engine system materials like plastics, seals, metals, etc.? 3. Are there different types of gum, varnish and sludge? How does their formation relate to engine oil? 4. What levels of gasoline additives are beneficial and at what level can they be an expensive waste or even damaging to gas engines? 5. What does the term "engine deposits" include? 6. Why are there carbon buildup problems in some direct injection engines but not in others? 7. How do gasoline formulations and additives differ between US, Europe, Australia, Asia, etc and for what reasons? I love to learn, and appreciate expertise wherever I find it, but don't let me push you too far into any project that might take your life out of a healthy balance. Thanks again!

Thanks for the amazing information. Do you think I can use 0W20 in my 2014 Toyota Camry if I live in very extreme hot weather above 122F. My Owner's manual recommends using any oil viscosity from 0W20 to 20W50, and they did not specify and specific viscosity! I use Amsoil signature series 100% synthetic 5W30 right now. It is API: SP, ILSAC: GF-6, and Acea: A5/B5

[@LubricationExplained]

To be honest, you probably can - but if you've been using the 5W-30 with no issues I'd stick with that. The fuel economy benefits of moving to a 0W-20 are going to be pretty marginal.

[@chrisbradley3224]

Excellent video. Do you have any thoughts on low/mid SAPS oils and whether or not we have achieved parity from a wear perspective with full SAPS oils? Should one always stick with full SAPS if they have no emissions equipment to protect?

[@mytech6779]

It would be amazing to see an oil using all this modern tech but without the formula restrictions of catalytic converters. Basically a modern oil from a first tier oil company but made for old collector vehicles which often have different oil design requirements with flat tappet valve trains, possibly leaded fuel, intermittent storage, moderate rpm. (Low lead avgas is often used in old vintage vehicles car or tractor, partly for protection against exhaust valve-seat erosion but mainly because to avoid costly storage issues and short carburetor life common with the oxygenated fuels sold for modern highway use.)

[@LubricationExplained]

Racing oils. That's where all the technology is at. They don't have the restrictions of catalytic converters so tend to have much higher levels of ZDDP / other antiwear additives. Although the engines aren't using flat tappets, the higher loads of race engines necessitate a more extensive antiwear pack.

[@mytech6779]

@@LubricationExplained I will look closer at racing oils. I have been under the impression that racing oils are formulated with the assumption of very short drain intervals so they may not be appropriate for something like a classic muscle car engine that is driven on the street or an antique tractor. As a possible example, race oils might be insensitive to the TBN package. (High TBN mineral deposits would get cleaned during frequent tear downs and TAN wouldn't have time/moisture to be a significant concern relative to many other wear factors.) Really the vast majority of race vehicles are not in the premier leagues with million dollar sponsors. So many racers use flat tappet engines, as they are much lower cost and a bit lighter for the same strength(high rpm), and generally more reliable than rollers. (A little more friction but also fewer parts to get wrong.) Roller based valve trains are primarily a way to meet fuel efficiency and emissions standards. Thus many motorcycle engines, like amateur racers, do not use rollers. (Insignificant friction relative to air drag. And unlike cars, moto fuel use hasn't been regulated in most places.) Though motorcycle specific oils must also consider wet-clutch performance and act as transmission gear lube, because the most common configuration uses crankcase oil for all three parts.

[@kupasotomotif]

Just because thin oil is more efficient in Japan, some manufaceturer force the same viscosity to every country, even at tropics. As result, many motorcycle in my country have to change oil at 20% of suggested oil change periode because the oil already ruined. Many gets fuel dilution and depleting oil problems too. Damaged piston and cylinder are not rare.

[@LubricationExplained]

There's definitely second order effects. In most countries previous designation lubricants should be available as well.

[@kupasotomotif]

@@LubricationExplained I live in Indonesia. There is no second option. Many Japanese brand recommend same oil viscosity as Japan. Honda Motorcycle CEO even try to force 10W30 globally.

[@eeiko321]

Fellow crikey Aussie! I’m well aware of LSPI… i experienced catastrophic engine failure, cracking the piston. Before purchasing oils I always pay close attention to the specifications and will always buy API-SP due to having a turbo charged 2.0T GDI engine. However, two of the current oils for eg Nulon long life specifies both API-SP and ILSAC-GF6 . A simillar oil, Gulf Western only specifies API-SP But no mention of ILSAC-GF6 Given they are both Australian owned oils…essentially they’re both the same? I understand that both are governing bodies that set standards… But what does it mean? All oils seem to mention API but not all mention ILSAC (International Lubricants Standardization and Approval Committee) So if it doesn’t mention then it doesn’t meet their standard or can you assume it does, given the mention of api?

[@FeelFree3]

Would engine oil with extra zinc but lower viscosity for e.g. 5w20 give the same protection to the engine as engine oil with higher viscosity but less zinc for e.g. 5w30?

[@LubricationExplained]

The answer is unfortunately "it depends". Theoretically it could, but it really depends on the engine.

[@rbruce63]

In my 2012 Volvo S60 T4 the engine comes filled new with SAE 5W/20 but in the first oil change, the owners manual says “it’s up to you to keep using the SAE 5W-20 or switch to SAE 5W-30.” I live Costa Rica where temperatures seldomly drop to freezing except in the mountain ranges and for hours during the year and have been using SAE 5W-30 despite the fact that the dealer uses SAE 10W-30. I am now using an SAE 10W-30 with no visible down grade in performance nor fuel economy. I replace my oil and filter every 5,000 Km or 3 months…

SP addresses LSPI, but BMW LL04 blows it away in wear protection, sludge protection, deposit protection, soot thickening, aftertreatment compatibility and fuel economy. Oxidative thickening is the same (Lubrizol Specification Comparison tool). SP is only 'much better' in one area and worse in all others.

Are you saying it's been hard for Oil Manufactures to create a ow-16? I'm just curious on why some brands like Valvoline make it but some other popular brands dont.

[@LubricationExplained]

Great question. I think the market is pretty small for 0W-16 at the moment, so many manufacturers are probably waiting until there is wider adoption before they dive in.

[@kikikiki82]

So is it safe to use an 0W20 oil API SP GF6A on a 4 cyl inline4 non TGDI engine? The manufac actually only requires 0W20 API SN GF5, but I've been experiencing what I believe as a LSPI since it was brand new

Without knowing the specifics, most likely yes. GF-6 oils are designed to be backward compatible.

So most motorcycle oils probably aren't going to get the SP designation. If there's any friction modifiers in the formulation they interfere with the wet-clutch system on a motorbike.

Direct Injrction only + turbo is a bad combination for disasters, requires due diligence in routine maintenance. I've been using Shell Helix ultra 5w-40 which was recently API SP certified, worked well so far for the N55. Noticed Nulon Apex+ and Gulf Western - some 5w-30 meet API SP, hopefully they'll help the Skyactiv-G last. Bit l bit longer. Can't find good cars like GH Mazda6 with MZR (port injection), dual injection might be a good alternative but complexity isn't going to help even if they are made by Toyota 😮

Dropping calcium additives from 1200ppm to 800ppm equal to reduction by 1/3. From 2005 to 2015, companies like BMW, Toyota, VW, KIA and few others have somehow messed up designs of their pistion-pistion rings. This leads to high engine oil consumption of >0.5 quart per 1000 miles. These "consumed oils" and their additives will eventually get into top of pistons and later onto catalyst. Logically, this will quickly lead to failing of MOT test. Good engines should not be consuming more than 1 quart engine oil per 6000 miles. Regards.

Get rid of low tension piston rings & low tension oil scrapper rings. I think ICE must be designed to have maximum engine oil consumption of 0.1litre for every 1 litre engine capacity for every 1000km travelled, doing at 100km/hr and the engine had done total of 50,000km. Basically a 2 litre capacity ICE should not be consuming more than 0.2litre of engine oil after travelling 1000km at 100km/hr. Otherwise it is pointless trying to limit calcium or zinc to 1000ppm in trying to avoid damaging or impairing the exhaust catalyst for emission control. Yes, No. 🤔🤔🤔

[@nozrep]

i do find it hilarious how “they” got away with the whole “stop-start” bs. Which involves moving parts, which in turn increases wear on the engine over the life of the vehicle, which in turn, causes more waste in the long run, thereby canceling out all supposed short run mpg “savings”. It is hilarious to me that “they” got away with that stupid rule, and also quite saddening that more customers are not aware or informed on such simple mechanical concepts. Oh, right, go ahead and repeat to me the fun marketing lines of how they improved the starter mechanisms to handle many more thousands of start-stop-starts. I love laughing at folks that tow the line like that. 😂. At least there are plenty of places to go get a simple “start-stop” delete installed on the vehicle, well in the States anyway.

Stop-start is absolutely no problem when engineered properly. Hybrids have been stop-starting for over twenty years. When's the last time you heard of someone's Prius having an electric motor failure?

[@LubricationExplained]

Yeah stop-start isn't so much of a problem once the engine is up to temperature. What can really kill the engine is a lot of very short trips in the modern, small, GDI engines. The fuel dilution produced lowers the oil viscosity, and if the engine never gets up to temperature the fuel doesn't volatilise off. With more and more short trips the oil viscosity continues to decrease....
