What are the differences between race car oil, like the oil used in NASCAR, and the oil used in our everyday road cars? NASCAR oil regulations are fairly unrestricted, allowing for unique formulations, whereas road car oils need to meet very specific industry requirements for certifications. In this video, we’ll dive into the differences between engine design, drain intervals, oil viscosities, oil additives including zinc (ZDDP) and bespoke versus mass market formulas. I spent time discussing these topics with Mobil 1 engineering, Roush Yates Engines, and Stewart Haas Racing to find out more. Watch for all the details!

    Is there any concern with running an engine oil with high sulfur content in the additive package? Anyone have any thoughts?

      In another of your videos you talk about the size and shape of oil molecules. Are FULL synthetic molecules a different size and shape than 100% synthetic molecules? I watched a different ideo posted by a different Utube channel that said the molecules are different. I am not sure so I am asking here.

    Nice video. There is soo much misinformation and myths\assumptions when it comes to engine oils. You eluded to it, but the definition of lubrication in an ICE (Internal Combustion Engine) is the flow of oil over surfaces. This hydraulic barrier is what keeps metal parts from touching and wearing. It is not present on startup no what the ambient air temperature is. For ICE "road" engines, the target operating temperature of the engine oil is 212 degrees F. Higher viscosity oil is only needed if you will routinely see higher oil temperatures or to maintain the hydraulic barrier in worn out\high clearance engines.

    Do you think NASCAR would even give this guy a clue as to what they are doing with their oils. I know Jeff Gordon's head mechanic and they mix their own oil and it's still petroleum based. They sometimes joke about the synthetic oil advertisements on the side of the cars.

    Are the catts the main concern for higher zddp oil? Would it be beneficial for engine longevity on a high km cattless engine to run extra zddp?

    • highrzr
      highrzr

      Yes, but the O2 sensors as well. It's more of a concern with forced induction engines and engines with low friction piston rings which are a good chunk of modern engines produced. It's why an effective oil catch can is so important in these engines.

    I live in Florida so it's never really cold. I run Mobil1 15-50 with an additional QT of Diesel Synthetic just to boost the ZDDP. It's in EVERYTHING - truck, boat, bike, mower. I want the extra protection of a thicker oil and the 1 YEAR drain intervals. Oil breaks down over TIME, so it might come out as a 10-40 ...I would NEVER want to start with a 5-30

    So to summarize the portion of the video on the use of ZZDP : Use large quantities of ZZDP if possible; Remove all emissions equipment including catalytic converters for better performance and cost procurement over time. Sounds like a plan.

    I use VR1 racing oil in my daily that's sr20ve powerd. It doesn't have a cat or any emissions equipment due to it's a jdm swap so I'll continue to use it for the benefits the higher zinc provides especially considering I rev to 8,200rpm daily.

    We need to experiment with MR fluid, ferrofluid and self-siphoning fluid lubricants. MR fluids are pretty neat because they increase in viscosity in response to electromagnetic fields, meaning that you can choose exactly where they are high in viscosity versus low in viscosity, but unlike ferrofluids they aren't necessarily attracted to magnets, and thus they can still flow freely. Meanwhile, ferrofluids can basically be forced to adhere to any parts that are slightly magnetized, thus preventing metal to metal contact and effectively creating a frictionless surface. Then there's self-siphoning fluids... These are exactly what they sound like.

    I put about an additional ounce to 2 ounces of zddp on top of 16 ounces of high-mileage Platinum Pennzoil for my stroker mini bike. Because of the flat tappet cams used in small engines. I will say I put probably 1400 miles on that engine beating it up, as like a sleeper road bike. So far no problems I will say I do feel a slight reduction in power but it's still reaches its top speed and has plenty torque

    Use the automotive oil that meets the API classification that the manufacture requires. Racing oil, small engine oil, motorcycle oil, outboard oil etc. have unique additive packages. Don't believe cock and bull stories from people who do different things than what the manufactures recommend.

    Very informative Jason! I'm a weirdo who cares about the environment yet enjoy driving my cars on a the track. I've a miata which I drive on the road as well as the autocross track. After watching this video, I'll start using racing oil in the engine when going for events along with replacing my stock cat con with a test pipe just so I dont poison it for when I'm using it on the road (and inadvertantly polluting a lot more)

    Racing oils work wonders in small engines and equipment hydro systems, as the extra ZPPD and phosphorus really allow the engines and pumps to last a long time. Road oils have much less of those because they ruin cats.

  • Kyle Langley
    Kyle Langley

    Simple answer NO! Follow the owners manual. Racing oil with high ZDDP can actually damage your catalytic converters and cost you money out of pocket IF that engine oil is out of spec. With all that drag on the pistons it takes forever to heat up the engine oil. Once it does heat up, racing oil holds heat longer, which is great when tracking but terrible for short commutes on road cars with stock plastic intercooler and radiators. If you tuned your car, contact a lubrication specialist. They’ll help you decide based on YOUR VEHICLE APPLICATION. Not bro science. Not the forums.

    Nice One Jason!!! I use for my BMW M2 BMW oils. My Lexus also using Lexus oils. Never had one issue. I used to be the dude who was also at the local store trying to buy the next best oils and filters. Because I did not trust the dealer oils. I know now that oils are built to run with that engine setup - Great video!

  • baja kitesurfer

    Jason ! Can you please consider making a video as to why ICE Automobile manufacturers have never offered any type of engine oil system ‘pre-lube’ or engine oil system pre-pressurization prior to engine start ? It seems in your discussions that that there is a fair amount of opportunity for metal to metal direct contact prior to the lubrication system fully pressurizing , perhaps even more so i’m very very cold climates with cold engine starts. Perhaps you could explore the cost/benefit analysis of pre-lubricating the (ICE) engine (s) prior to engine start. It seems as though the Cams and Lifters on ICE engines are or can be especially vulnerable to higher rates of wear due to those periods where the engine is turning yet prior to a fully pressurized lubrication system. I’d love to hear your thoughts on the matter and perhaps some consults with a few engineers at at the major ICE manufacturers. Thanks Jason -!

  • Daniel S
    Daniel S

    Oil change intervals aren't just a mileage interval but also by a calendar interval, e.g. or 12 months. So if you car does 1500 miles in a year you need to change the oil because it is a year old. The other thing about road cars V NASCAR is that a road may have to do a dead stop from 70 mph upwards (approaching a roundabout at speed and then seeing at the last moment it isn't going to be clear as you thought and rather then proceed onto it you have to make a dead stop). The road car won't be dry-sumped and may experience surge under braking (negating the use of lower viscosity oils).

  • mark warnberg
    mark warnberg

    This still does not expalin the Viscosity Index where higher Viscosity withstands heat better. Logical thinking say´s that high performance engins run HOT, very hot when the oil is going through a Turbo Charger and thus need more protection! The 16-20 weight oil lubrication falls off at a certain heated point so in order too maintain the engins performance the oil weight must be increased to 30 or 40. So WHAT IS GOING ON WHEN AUTO MANUFACTURERS RECOMMEND SUCH LOW WEIGHT OIL???

    IMO if you track your car, fill with a race formula for your event because the added zddp will protect your bearings at high rpm/high heat. Then just drain and refill with oem after the track day for daily driving. Changing oil is cheaper than changing engines.

  • MrEqtube
    MrEqtube

    I have only one gripe about this video: please, stop talking about "tolerances". Engine has clearances. The clearances have tolerances. Points to that oil viscosity is not referred as "weight". There is no such a thing as w30 oil; it is an oil, that has viscosity grade that can be classified as SAE 30.

    Mmm I'm an engine builder..all engines have metal to metal contact in some way, plain bearings are still used in crankshafts,overhead cam engines use shims for valve adjustment and then there's timing and distributor gears you cannot rely on oil pressure/film...Always use oil with a high zinc people and replace your cat converter every 50thou if you are worried.

    Other than sounding like a snake oil salesman... Switching from flat tappet to roller tappet removed the need for zinc. BS. Ever seen the number of roller cams that wear flat? It’s just as necessary. I get the need for thin oil with cam phasers, but sacrifice the rest of the motor for it? I’ve only lost 2 motors in my 45 year career in automotive. Both were running pisswater oils. 0-20, etc. synthetic. Never lost a motor on 20W-50 Castrol. Some of the sludge I’ve seen where synthetic oil was used should be an embarrassment. Very common. And destructive. Synthetic has run its course. Snake oil for the masses!
