Should You Use Racing Oil In Your Road Car?

What’s the difference between road car and race car (like NASCAR) oil?

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! #Mobil1Partner

I tried racing oil and now my car doesn’t run right. I’m going back to gasoline.

“Road cars are rarely at full throttle”
Me *nervous laughter*

I'm confused, I need the white board.

3:55 "road cars are rarely at full throttle"

I can't be the only one...

"Full throttle and almost 90% of the time" sounds like me driving my miata...

[pleasedontwatchthese]

4:08 "90-95% at wot" that reminded me of when I use to drive small cc motorcycles. everything felt like a race on that thing

I would like to see a video on the "lifetime" transmission fluids that some car manufactures are putting in their vehicles now.

I’m that guy that would spend $600 on an oil change, and eat ramen for 6 months. Worth it. 😎👌🏻

Great video! My '96 Accord is at 386, 000 and I plan to exceed 500k on the engine. Regular maintenance is key!

Way way back in the day. The engine manufacturer of a vehicle I owned strongly recommend 10 w30. I thought I knew better. 15 w50 has to be better! Wrongo bongo said a few main bearings. The oil passages in the block and cylinder head were restrictive to the thicker oil. Sure the oil pressure gauge read higher. My uneducated choice was starving the bearings of lubrication. For a High School kid it was a very bitter pill to swallow. Conversely too thin and the same result.
Everyone can armchair engineer all they want. Use the oil the manufacturer recommends.

EE: Should you put racing oil in your street car??
Me: Good question!

One of these on diesel engine oil would be interesting. Especially the whole CK-4 (Compression ignition rev K, 4 Strok) and SN (Spark ignition rev N) compliant oils, and the Ford TSB on it. Made me dig way deeper into the actual oil certifications.

Glad to see we're talking about ZDDP today. This is the big debate in my Jeep YJ group. We get the joys of flat tappet lifters AND catalytic converters.

What I find the most unnerving about modern engines and lubrication, is that we still can't buy a vehicle equipped with a prelube system from the factory. As much as 60% of wear occurs at startup. There's absolutely no reason why they can't plumb an engine with with a pressurized prelubrication system. Mercedes did it back in the 20s, and it should've become an industry standard.

"Imagine owning a car that needed oil changes every 500 miles"

What I’ve learnt ( the hard way) is race brake pads, track tyres, track suspension, ect ect don’t work as well as the same road items on the road.
Race oil is no different .

[edwardojr]

Absolutely right.
I have to order my high zinc oil from Summit, for my flat tappet engine. The majority of off the shelf oils are detergent oils and do not protect as well as my high zinc oil

[P]

i've been buying new cars for 40 years. i change the oil in them with the current spec. regardless of brand. never had any perceptible engine wear. the interior and body ALWAYS degrade first. why the drama over the "best" engine oil? if it says racing on the label--it's for race cars. now i'm done.

High ZDDP (and highly priced) Joe Gibbs oil for my 996 engine soon to fight that inevitable bore scoring...at 6 month recommended change intervals.

But zero weight wonder elixir for my Prius Prime; what a crazy world we live in.
