I’m so glad I got my oil tested through SPEEDiagnostix on my 2024 Subaru BRZ @ 555 miles. My oil (from the factory was below viscosity at 100c = 6.9 Additionally my silicone was highly elevated at 793❗️along with copper=90, tin=20, manganese=12, total metals=151 AND wear at 1000 miles=272.1 Although these numbers are not very alarming for a brand new car breaking in…. I definitely want to keep a close eye on the numbers “especially” the silicone due to known RTV issues with the FA24 motor. If you hope and or intend on keeping a vehicle long term, like me… I recommend testing your oil regularly.
I believe you channel is probably the only one out there that looks into real data and answers real question not just expressing personal preferences like many others. Finally we have somebody who approaches oil topic professionally and scientifically. Where have you been before?! Thank you!!
Thanks! I spent the last 19 years helping race teams win world championships through the application of Tribology. Now, I’m here to help everyone else…
Love these videos, Mr. Speed. Your video on Mobil 1 15w50 helped me understand why the oil has treated me well for many years. I currently run it in a host of vehicles, whether it be a BBC in my flat bottom v-drive boat, 500whp Mazda RX7 (Wankel turbo), and every single motocross bike I have owned for the past 20 years, the 250 four strokes turning well over 14k RPM. It seems to work extremely well with wet clutches as well. Never a slippage issue and clutch disks hold up though extreme abuse. Enjoying the videos, great work on the Total seal and factory tour videos as well. Love the enthusiasm.
Thank you very much Lake for taking the time to make some of the most informative and educational videos on this "lesser known" topics. You're a wealth of knowledge. Greetings from Argentina!
Very useful info. Can you pls do a clip on why GDI turbo engines need synthetic oils to ensure long term reliability. Many dont understand the complexity and the high temperatures and pressures those engines are subjected to not to mention fuel dillution and carbon deposits on the back of valves.
2.0 ecoboost engines are very hard on oil. The Oil life monitor on my wife’s says 9-10,000 miles per OCI but I see the fuel dilution is the limiting factor.
Hey make a good video on Duralube I always liked how the bottle looks; but I don't use oil treatments because they mess with the additive levels of the oil.
Some people have the opinion that even with a pristine UOA, an engine can have varnish or sludge build up because those things are out of solution and will be undetectable. Is that true? Or can be trust that as long as the additive package is good, varnish and sludge are not forming?
Shifting gear here just a bit, asking a question on gear lubricant, in the old days unless a seal went bad and leaked out the gear oil or water mixed into the gear box and contaminated the gear oil you never seen bearing failures with old conventional as they say dinosaur oils but ever since synthetic gear oils have came out we see numerous bearing failures in transmissions and differentials as low mileage as 80,000 miles and see 1960s trucks and cars still with all original gears and bearing going on 300,000 miles.. Some say it is the metal I feel that it is lubricant related because I have noticed the over the years ever since manufacturers have been using synthetic and switching from conventional lubricant. If anyone could figure this out I feel you are the one that can.
Thank you for these videos! Regarding the oxidation value of Mobil 1 0w-40 FS, how high would you say is too high? I have sent a number of samples to SPEEDiagnostix, including 2 samples of brand new oil (straight from the bottles), and those came back with values of 36.7 and 35.7. Per some advice from Jake Raby, I have been experimenting to see whether it makes sense to change my oil once per year (Fall, right before winter storage), or twice per year (right before winter storage, and right after winter storage). The car only sees about 2500 miles per year. Jake suggested that the key factor would be how much the oxidation value increases during the 5-6 months that the car is in winter storage. So far, I have not seen any excessive oxidation happening during the winter storage months (considering that the analysis of two brand new samples had a variation of 1.0 between them). Thank you!
Thanks for the question. We should probably do a video specifically about Oxidation values, and how it relates to different oils. In your case, Mobil 1 0W-40 is a PAO / Ester blend, which is why the new oil oxidation value is nearly 40 to begin with - Esters contain oxygen atoms. Because of this, Ester blends age differently than other oils (that don’t naturally contain oxygen atoms). Quite often we see Ester based oils drop in Oxidation value as they age, so we’d suggest changing the oil if you see a change greater than 10 above or below the starting value of 35. Of course, the best way to determine oil change intervals is the wear rate. Keep extending the oil drain interval until you see the wear rate increase. Ultimately, the reason for the oil is to reduce wear.
Thanks for the question. It depends on how fast you want the results and how many samples you want tested. It can be as little as $41.46 for us to test your oil or up to $199.95 if you want the results in 3 just days.
I don't see Blackstone Laboratories reporting oxidation value on their reports? Also, for Mobil 1 0W40 European Formula FS, why would the reference viscosity range be 11.1-14.8 cSt? Mine was 11.78 cSt after only 1500 km of use in a 991.2 GT3.
That’s because Blackstone uses the older TBN test method, which is out of date for today’s fuels. Also, the SAE J300 viscosity range for a 40 grade is 12.5 cSt to 16.3 cSt, anything outside of that is not in grade, which is typical for Mobil 1 0W-40.
@@themotoroilgeek so I’m at a bit of a loss. I use 94 octane fuel which is beyond the recommended 93. Engine runs great. I don’t detect any clinical pinging and the engine is never lugged or run at load under 1500 rpm. The rest of the UOA looks great. Surely Porsche would know that M1 0W40 is low on the viscosity end? Should I switch to something else? Keep the M1 0W40? My OCI is already very low between 1500-3000 km once yearly by time not mileage. Surely at this rapid OCI there’s some mitigation of risk?
@@shahrukhbakar3248 If you want the lowest wear rate for your Porsche engine, I'd use something different. I also have a Porsche, and I use the Driven DI40. We see very good UOA results from that oil at 4,000ish mile drain intervals.
@@themotoroilgeek How do some of the other oils fare, like Motul or LiquiMoly in the same application? 0W40 vs 5W40? I do use my car in cooler weather but generally nothing below 0 degrees C so minor cold starts but most of the time I always run the car to full temperature and no short runs.
@@shahrukhbakar3248 We also see good results from the Motul 8100 X-Cess GEN 2. If you want to stay with Mobil 1, the 0W-40 ESP doesn't shear down like the Euro formula does.

Very thorough explanation of the chemicals in your oil.
Really enjoyed the honesty and accuracy..!!
Hi SPEED-X !!viscosity/100C the higher the better? Please make a vid for other parameters like TBN,ash,density,dynamic viscosity,viscosity index ,flash point etc.And how to evaluate all these together!!
Thanks for watching. I appreciate the suggestion.
Please test mmo synthetic
Do you have a database of VOA for most oils to establish the baseline or is it necessary to test virgin samples as well used?
We have baseline VOAs for several oils. A virgin sample is only needed if you have a unique, specialty oil.
What could be the reason of v100 thickening after 8k miles as seen from UOA ?
Oxidation is the primary reason for thickening!
In general, how much oxidation before an oil is deemed unfit for further use? 4x the virgin numbers ?
@@overkillonslash That is the "rule of thumb" for most oils. That doesn't work for pure Ester or Ester blends.
