Engine Wear Metals After 16 Track Days

[@d.k.7710]

agree on that, to 127%... only issue with that: most of the audience / people out there are looking for "fun" and "entertainment" and only few of them are seeking actual information... so the most popular channels are either absolute pro combining both, or way more likely, entertainer pretending doing technical stuff at their won.

@@MarcusAntonius415 the cars in Greek islands have a tendency to rust badly. I've also heard many Germans that pressure wash the underside of their cars every day during the winter to avoid rust problems. The thing is modern cars are galvanized and should hold together for at least 8 years before rust signs appear. The fact that this Mazda has this much rust so early to me looks like poor metal quality.

[@AisuruMirai]

In the US, a company called Blackstone Laboratories does the same type of oil analysis. They provide universal averages for the elements measured in the oil, so you can get a sense of how "normal" your oil is. Below are the universal averages (in parts per million) for wear metals for a car with about 100,000 miles (my car's approximate mileage) and 5000 miles on the oil: aluminium: 3 chromium: 0 iron: 7 copper: 4 lead: 0 tin: 0 nickel: 0 manganese: 0 silver: 0 titanium: 3

Mazda have really made a great engine here and obviously made sure that cooling is sufficient and that the sump controls oil levels well so that the engine does not experience oil surge on track ! Great work Mazda 👍

[@qasimmir7117]

Your engine is nowhere near in the heat range or at high heat for long enough to require racing oil. Good bit of analysis like this saves a whole load unnecessary spending and effort.

[@PidseriaWinkleroni]

1:58 I highly recommend you to get the underbody etc. rust proofed with fluid film, mike sanders or something similar. For 3,5 years that amount of (surface-)rust looks really bad. My ND is a little over 5 years old and I just got it rust-protected. My chasis was completly rust-free, wich probably has to do with the fact that i am living far away from the coast. However I still drove the car daily over the course of 4 years, including in the wintertime with salt covered roads.

[@gamesmaster1060]

Things rust it's inevitable. Mine has been rusting like that since 10 years ago and there's no important damage. It's not that fast of a process unless you're driving on salt lakes maybe lol. Trying to rust proof and remove rust all the time is just a massive time and money sink.

[@PidseriaWinkleroni]

@@gamesmaster1060 excuse me, but thats a load of bollocks... if the underside of the car is that rusty after only a few years, you can imagine how it is going to look in another 5 years. if you plan on selling the car anyway, then whatever. but if you plan on driving the car for a longer time then taking 1000-2000 euros to preserve the car sound more like a good investement than a "money sink". its no secret that miatas suffer from rust issues, NA to NC it has been confirmed. in recent times the first few NDs are starting to fall victim to rust, and there is no reason why the ND would suffer a different fate than NA-NC in the future. Telling yourself that your car "has been like this for 10 years and its all sunflowers and sunshine" sounds alot like copium to me. the rust that you can directly see often isnt what causes non repairable damage; the bad rust starts for example on the inside of the frame, fenders, rocker panels. when you can see this rust its already to late, because only at this moment the car becomes a money sink if you choose to repair it...

[@gamesmaster1060]

@@PidseriaWinkleroni Ironic you say im coping when your the one that seems to be doing that. I have no reason to cope I am just saying that obvious signs of undercarriage rust happened a long time ago and had no problems. Maybe I will get problems later on but it would of took a long time to get there. Even longer for a car that isnt known for rusting issues

[@kremp1834]

I think a transmission oil test would be just as if not more important than a engine oil test; since I hear a lot more talk about the transmission wear in heavy track use for the ND.

[@danielcarvajalblanco3476]

Yes it does. I did swap the oil on mine once in 10k milles of trackday use.

[@cstrx11]

True true. The earlier the model year is of the ND the higher the risk for transmission failure (gears in 2016/2017 models), or if too new (2022 and 2023) synchros issues. At lease these have higher changes of issues, but the synchro issues are independent of the track usage.

[@averyalexander2303]

That would be quite interesting too, but IMO harder to conclude one way or the other if the track use affected the results since not nearly as many people analyze their gear oil, so there aren't as many results to compare it to. I'm not sure about these specifically, but as a very general rule of thumb, transmissions tend to wear out and fail before engines do.

[@floodtheinbox]

Mazda are in a completely different league when it comes to building engines that are designed to be thrashed. Seeing your oil analysis really drives that point home. I've been sending the oil from my 150k mile Mazda 2 off to have it looked at every 7500 odd miles or so since I've bought it, and the results from your car look bang on to what i've been seeing, save for the fact that my 2 is a dedicated daily driver!

[@HondaEnjoyer12]

250k miles on my k20 in my integra and still brand new. Revving to over 9k on stock oil pump and valves and pretty much last 100k miles have been fast road or track miles. I think any manafacturer should be able to make an engine that wont break down from 30k miles 😆

[@artemkatelnytskyi]

It's unbelievable how reliable an engine in a consumer car is. To be fair, it is still "only" 27,000 miles and about 7.8% of these miles are driven hard. Nevertheless it is still good result, though I don't have anything to compare it to. This is why I don't believe people when they say cars are built to fall apart after five years so that you have to buy a new one.

Great video, something to consider: While your oil is holding up well, post track days, it means your oil filter is doing its job, not allowing metal particles back in to float about. Periodic compression testing is another metric. Heat is your #1 enemy, so consider short shifting when temps rise on track. Glad your enjoying car for what its engineered for!!

Great video I think copper is part of the cylinder head assembly I change my oil every 5000 KM and push the engine a LOT but unfortunately there aren't any oil analysis centers in my country

[@SuperVitz]

Great content. Some thoughts, years ago I watched a Japanese video where the tuner said that we should pay more attention to the gearbox oil after doing track days than the engine oil. He was saying that the manual transmission oil goes through a lot more stress on a track than the engine oil does. Also, surprised and impressed that you're using Mannol. I only really use that on my very low value cars that already burn/leak oil. I think they don't carry any manufacturer approvals so whilst they say they've designed it for VW or Renault etc. specifications, no one has actually verified that they meet those standards. That's why you don't find them in any car dealership, or national chain style garages, or most motor factors. Good to see that the oil analysis looked good, I wonder if it would've looked better with a premium oil such as Mobil1 or Castrol etc. maybe in another video?

[@RichardFanders]

According to the data sheet the oil I used is approved by: Ford, Volvo, Jaguar, Land Rover and Fiat. I also use mannol in my SEAT Leon, which apparently has VW 504/507 approval. Not had a problem with the oil yet, just seems like good value to me. Do you have experience with mannol being below quality?

[@SuperVitz]

@@RichardFanders if you look at the datasheet, it says "approval RECOMMENDATION" and then lists a bunch of OEM standards for oil. Now compare that to Comma XTech 5w30 for example, they list the OFFICIAL APPROVAL from Ford for a particular Ford standard, and they even provide a Ford letterheaded document that confirms that Ford approve that particular oil for that particular standard. Basically, any oil manufacturer can say that they have designed or blended their product with a particular OEM standard in mind, but the more expensive oils will actually have the product approved by that OEM. Getting it approved costs money. There is an argument that it only really matters for engines that are still under warranty, and I do sort of agree with that notion... You've done the testing and confirmed that this oil is perfectly fine, the only thing more interesting than that would be to do another test using a more premium oil that carries lots of official approvals to see if the used oil analysis shows anything different. I'm not hating on the Mannol stuff, I buy it in bulk for our family fleet, we just don't use it in the higher value cars for that extra peace of mind because they don't go through that manufacturer audit process. Btw they may have gone and got official approval for some of their oils now, they have many many varieties, I only confirmed the above for the particular oil used in your video!

[@sinan325]

I love your MX5 videos, very informative.

[@andrewglobe3213]

morning Richard very interesting video the calcium is part of the additive package in the oil but it is a small amount in the oil these days they use magnesium instead as this helps to stop low speed pre ignition in turbocharged direct injection petrol engines. the lead and the copper will be from the big end and main bearings on the crankshaft but you are right nothing to worry about. I went on a visit to Millers back in the early nineties the were using a mass spectrometer even back then.

Richard as always, a great analysis. It's good that a KZbinr goes into the actual science of this stuff which is what other chanels lack, and it allows you to put all the heresy and conspiracy theories to bed.

Mannol is quality oil. I've ran Mannol oils in my car and family cars for a few years now.

If it meets the specs (ACEA, API, manufacturer specs etc) it's a good oil. Never really saw many used oil analysis data from Mannol oils so thank you for that video. Just reinforces my belief that spec equals good oil. Also, Mannol is dirt cheap. I can get the oils that I need for about 4€ per liter.

Many other cars wouldn't survive it. 😝 Your oil seems to be very fine. I am also using a little bit thicker oil, 5W50, since I also trackday my car from time to time and I think it serves this engine well with higher load. I have factory oil temp gauge and on track I keep it around 110°C, not exceeding 120°C. While daily driving, oil temp is around 90°C, on Highways or in the summer in city jams goes up to 100°C.

Calcium and Magnesium content indicates detergents and dispersants. Zinc is a measure for ZDDP which is an antiwear additive. Molybdenum also indicates antiwear additives, as does Boron.

Interesting video....I've always wondered about sending oil off for analysis, just to check if sticking to manufacturers oil schedules is the best thing to do or not. Im not sure where Mannol oil sits on the quality scale but I'd be tempted to step up to a more premium oil. I'd agree that if it meets the manufacturers spec then why would you spend more but it has been proven that premium oils not only meets the spec but goes beyond that with an even better (wear and detergent) additive package and better flow characteristics after time. FYI....Boron and Molybdenum are friction reducers, Zinc and Phosphorus are anti-wear additives and calcium, sodium and magnesium are detergents.

[@FlyingPhysicist]

I've been using Mannol 5W30 C3 for as long as I can remember. The Moly content (def an anti-wear additive) was 43ppm on a recent analysis. You might consider switching from A3/B3 to C3, at the additional expense of £2 per 5l...

[@j2w1_lub]

nice video! (like how you changed the title!)

[@allthehandlesweretaken]

1 ppm moly. is probably leftover from a diffrent oil that used it as a friction modifier. 7 ppm silicon can be from airfilter yes, but also from a oil filter. seeing copper is a bit concerning if it's from the bearing, as these are not supossed to wear. millers have a ''trackready'' oil called ee performance, wich is ment for regular road but also trackdays. might be a good fit for you

[@xynostasos9022]

There's no oil "designed for an engine". If you watch the Speed Lake Jr videos, you will know that the single most important factor when choosing and oil is to know its operating temperature. Does your car have an oil cooler? If yes, then maybe you are fine with using a 5w30 oil. If not, I'd go with 15w50 high ZDDP oil or even 10w60 racing oil (which you of course dump after the track day is over). Ford for the Coyote 5.0 engine (Mustang GT) recommended 0w20 for normal use and up to 5w50 for racing use.

Silicone may be from gasket sealants. Calcium may be the detergent. Zinc may be anti wear additive.

Very intersting especially as I also use Mannol FR in a 4Cyl that sees track time (although nowhere near as much). I have considered going for 40, but the oil pressure is already so high and holds quite well all the way up to 100c and beyond, I haven't bothered. Going slightly into the 20 range isn't a concern given most 20 oils will also get thinner with time - so it's still thicker than if you had used a 20.

5:36 I would periodically use a "complete fuel system cleaner" fuel additive that has PEA in it as it could help reduce fuel dilution a bit.

[@balazshorvath898]

Viscosity dropped maybe because of the cold start just before the sample. Petrol during cold start can cause it, if you don't warm it up properly.

[@piotrmalewski8178]

3:22 - 5W30 and lower viscosities were introduced for legal reasons (emissions) and to lower fuel consumptin but they are not necessarily good for the engine. As a rule of thumb in any track day/autocross, other motorsport used car you should switch to at least 5W40, and preferably 5W50 to lower the risk of breaking the oil film under full load in high temperature. Another problem is, that if you go on racing tracks you are going to have high side g forces taking away oil from oil pump's intake, so you better do 'dry oil sump' modification. The lack of these and use of 0W20 oil is what's killing Subaru BRZ/Toyota GR86 engines. The whole viscosity recomendation is a complete bias, again caused by legal reasons in the EU. If you search for manuals for exact same engines they will have different recommended viscosities depending where the car was sold, and how strict the local emission regulations are. An engine that has recommended viscosity of 0W20 in Europe, often has oils such as 5W40, 10W40 and even 15W40 in American or Central Asian markets. I just wouldn't recommend 15W40 because it has a tendency to cause 'dry start' and leaves dirt in an engine. At least older 15W40 oils did.

[@__-fm5qv]

copper I'd assume is an additive of sorts? You're right in that if copper was in the bearings or something it would likely be coated or plated. For example, chrome plating is often used in the aerospace industry on bearings because of its low friction and high wear-resistance, so that would perhaps be one to watch out for.

I assume it will suffer from carbon build up at some point but as I drive it hard on track it may be better. Time will tell.

Just pick your track, check their calendar on their website and book a trackday/evening, it's that easy mate. No insurance required, just make sure your car is well serviced. I recently had a track evening at cadwell park in the wet. Cost 90 for track time, spent 50 quid on fuel, used no oil, used 1mm of tyres and brake pads Cars are meant to be used, send it

[@benjamin.szepvolgyi]

Just a correction. It doesn't mean it's better on track because you put 5w30 into the engine instead of 0w30. the 0w is better in most cases at the start, and when the engine is still cold. No point in putting 5w into it. And into a turbocharger engine, you should put the thinner oil.

[@RichardFanders]

I was comparing 0W20 with 5W30.

[@PROofHAPPYWHEELS]

Does it matter if you sample the oil from the start of the drain vs towards the end/bottom of the drain? I imagine sediments would sit more towards the bottom but probably doesnt matter if the oil hasnt sat for too long.

[@Paynos]

This is properly nerdy, good stuff man. Are the NDs worth sticking a baffled sump in?

[@RichardFanders]

Apparently from factory they can do 1.4 sustained lateral G and maintain oil pressure. No modifications needed for driving on track with road tyres. Only high temperature brake pads.

[@Paynos]

@@RichardFanders that's really excellent. Pulling a G laterally for any sustained period is really going some in a road car. Only would really need touching if you're going on slicks/really crazy semis then. Hope you're well man!

[@RichardFanders]

Hope you're well too. I think even British Touring Cars only peak over 1.4 G, if I was starting to get anywhere near that I would want a track prepared car with roll cage and harnesses and be in a position where I was less bothered about damaging the car as there is not much margin for error cornering with that level of force.

[@TheVVumpus]

It really makes me wonder how long an ND2 drivetrain would last if driven as delicately as possible. The world may never know..1..2..

[@aygwm]

I don’t understand why people get the engine oil hot before draining it. Cold oil just takes more time to drain but it will leave less oil in the car becase less is stuck up in the engine. Bonus: no risk of burns. Who’s in a hurry changing their own oil anyway?

[@gasolinefumes]

I always change mine cold!

[@RichardFanders]

That's a valid point.

[@whiteprideisnotacrime1685]

After 10 mins with the engine off 99% of oil is returned to the sump

[@PaulHojda]

The engine may be mint, but I'd get that undersealed if I were you. Quite a lot of surface rust for such a young car.

[@Wrecker1738]

Oil question: my Suzuki car also accepts 0W-20 and 5W-30 and I noticed that it runs smoother and quieter with the 0W-20, so that's what I use for daily driving. I did not start to go track days yet but I plan to, and I thought that I would change to 5W-30 before the track day and then back to 0W-20 for my daily driving. Would you see a problem with this viscosity changing, since some amount from the old oil will always remain in the block/sump? Thanks :)

[@RichardFanders]

I've not seen a problem. I've always used 5W30 though. I assume the factory fill was 0W20.

[@lptomtom]

I hope he waits a little more to change oil next time, the test proved it was unnecessary since the oil was still good

[@e630fnr]

I’d worry more about the underside rust! You’d be better off spending your £40 on undercoating mate!

[@Ferraridude13]

How hard do you push engine on track? Early shift or just max revs all the time? And what mpg do you get? I managed to get around 14mpg (US) in my stock NB on track.

[@RichardFanders]

I only shift early if it helps me. I generally use all the revs.

[@Aspen90]

What about the diff oil? How often do you replace the diff oil, I’ve just got my MX5 and I’ve done it just to be sure as I don’t know the history.

[@RichardFanders]

Twice so for, about 18 months each time.

[@shizusensei4942]

informative

[@davidzebar6876]

Was the car driven in the salt/snow? That's a lot of rust for a 3 year old car

[@RichardFanders]

Yes, gets driven in all weathers and has been to the alps twice.

[@animationcreations42]

Ah, oil changes. How I wont miss doing them now we've gone double electric with the cars! Actually, i tell a lie, I did actually enjoy faffing about with the cars, now I've got to find something else to do!

[@strobi0001]

I was a bit surprised that you trust that brand of engine oil. And I think modern street legal cars without actual cage and bucket seats are designed to be safe without wearing a helmet. Sometimes a helmet can cause more injury than safety.

[@RichardFanders]

I've not had problems with this brand of oil. There has been a few comments about the brand on this video but I've not heard of anyone having a problem with it. I buy it as it's up to standard, is manufacturer approved and good value.

[@thecringegod4808]

That is the rustiest ND i have ever seen christ looks like itd be 15+ years fucking salt...

[@inn6300]

youtube said i needed to take my car out and give it a beating
