Lake SpeedJr. (Certified Lubrication Specialist & Oil Monitoring Analyst) is back to talk to us about the causes of Low Speed Pre Ignition and how to prevent it.
In this video we take a more in depth look about why you shouldn't ignore LSPI if you have a direct injection engine, some of the causes, as well as how to prevent it.

What I don't get is why an emulsionated oil in sump would cause issues with octane level. The injectors get the fuel from the tank, not from the sump... or pcv return would make so much emulsion injestion that would lower octane intake to the point of detonation?

[@fabianortiz482]

Can this happen on cars that aren’t direct injection? I’ve been hearing a slow but fast hard rattling and I feel in on my steering wheel and pedal after I put test pipes on my g37

IMPORTANT NOTICE : For those who have a GASOLINE Opel turbocharged engine : Dexos 2 (based on ACEA C3) is NO LONGER ALLOWED because of LSPI risks. You MUST use Dexos 1 gen2 (no matter the brand, the important is that the oil respects the Dexos 1 gen2 requirements). Dexos 2 remains allowed ONLY FOR DIESEL engines.

[@bobl78]

also some port injected engines are affected by this

[@K03sport]

...how do you ID Dexos 1 vs Dexos 2? Is it directly on the label, or do you have to go the oil manufacturer's site and find the oil type there, then go buy that oil? Oil bottle labels are 90% marketing to get you attention, so how do you ID the right oil?

[@JRCW892]

@@K03sport It's clearly written on the bottle

[@aciddiver1978]

Yes, dexosc1 gen3 for only direct injected vehicles. Prior direct injection(2016) still can use dexos 2. According to opel dealer here.

[@dsport]

It's almost like KZbin knows you had an LSPI problem once or twice haha

[@XWMaster]

@DSPORT Do you know why this only occurs at low piston speeds? Ive been researching LSPI for a while and can't find elaboration on this anywhere. If you know of any articles you could link or info you could provide it would be much appreciated!😁

[@boolean5162]

Very interesting and informative. A couple questions though: Why does this happen most at low speed? Is it due to the slow airflow speed into the combustion chamber and long time between Sparks, giving the fuel more time to mix with the oil? Also, how is there enough oil above the piston rings for the oil to dilute fuel octane, and yet the oil typically isn't burning in non LSPI scenarios? Does a larger ring gap, and therefore a larger region of the cylinder wall that hasn't been scraped down to a film of oil, affect the likelihood of LSPI? Thanks again for the cool video.

[@stiggy60426]

Yes, & Yes. Also remember most cars have a crank case ventilation system that will reintroduce un-burnt crank case gasses back into the intake track and these gases almost always have an oily residue, along with the EGR and thats where your soot comes from although egr soot is less of an issue these days.

[@andrewraczka657]

What fuel additive would you suggest for a 2018 Alfa Romeo Guilia Ti Sport 2.0? I had an oil change at 10k and 17k miles. Found out after the fact they used Mobil 1 0W-30 Advanced Full Synthetic. Think I will use API SN PLUS and change every 5k miles from here on out. I expected SN PLUS to be used the first two times, but was fooled. I have always used premium fuel. I drive very aggressively. I get it up to 5,000 or 6,000 rpm every few red lights. Thanks!

[@tutorialesbuler]

Hello, what would be the maximum limit of calcium to be calm?

[@TotoGeenen]

When I tank LSPI no notciable LSPI occurs. (Was very noticable before). Does this mean I can safely drive at low rpms or should I still avoid it? Also, I have an NA indirect injection car. I thought LSPI was mostly a problem with DI and turbo vehicles

[@KDuB9I6]

Hi guys, my Ford Fiesta ST makes max torque at 2500k RPM. Is it bad to go WOT at that low of RPM? The power in that low range 2500-3k is so amazing, but am I ruining my motor?

[@clubsportf56s48]

So which European spec oil do i need to use to prevent LSPI? It killed my engine too..

[@xtra1234]

There should be no oil on the cylinder wall on an Ecotec motor during compression. But maybe a 2 stroke that is mixed with oil.

[@lickmynukes9864]

Does LSPI occur with DI naturally aspirated engines as well? And if so, is the issue less common than with a turbocharged engine?

[@Ezekiel-OffRoad]

Yes I can confirm this as a owner of a 2013 Hyundai Accent 1.6 gamma gdi the engine only lasted 80,000 miles and that’s with me being aware of the issue 6 years ago When the car only had 10,000 miles on it I did everything I could to combat the problem including installing a oil catch can switching to premium fuel installing a cooler thermostat and cooler spark plugs.

[@mkkhalid23]

My car is port injected honda IDSI 2004 engine It still knocks at low rpms with AC on. In other words high torque at low rpms triggers LSPI. WHAT can i do

[@warriormonx]

Any word on commercialization of a low calcium / high molybdenum 40W oil?

[@lordofbees9067]

ARE YOU LUNATIC? NOBODY PUTS MOLY IN OILS-- ITS EXPENSIVE,,,, so they sure use graffite instead and they call it moly oil. other oils that have normal brand have no moly inside. Unless you buy it in pure form as an aditive you gonna get nothing of real moly in your engine oil.

[@tedtedness184]

Mobil1 5w-30 ESP has 1050 or less of calcium as all their non race oils. They may not be D1 G2 buy they would pass it if they tested it. It is also on the heavier side of the 5-30 scale @100C.

[@mbeacom21]

I thought LSPI was different from detonation. Why are they using the terms interchangably?

[@nkzag555]

[@TheWhills]

ST1 Owner, here👋🏻 I have a question for those more educated in this LSPI subject than I... Would deceleration in-gear also be considered LSPI? I’m used to NA VQ motor where I could accelerate and decelerate whenever I wanted. Just trying to not blow my motor!

[@boolean5162]

You will not typically incur LSPI while the engine is at a low level of load. Deceleration usually implies low load, so you're probably safe from LSPI while decelerating. Lean surges or something else might catch you, but probably no LSPI

[@grahamherbert3612]

Dexos 1 Gen 2

[@PiroFyre]

I would like to ask that guy how come Amsoil is the ONLY oil company that makes a 0W-30 that has all that API SN PLUS/Dexos Gen2 stuff. My Veloster N's oil cap and owner's manual calls for 0W-30. Even though I don't think it's completely necessary to run 0W-30 (like running 5W-30 would be fine), it just annoys me that there really isn't another 0W-30 out there in the market that has API SN PLUS certs.

[@dsport]

Hey, check out the American Petroleum Institute's website's directory. You can see all of the oil companies and the oil grade they offer, and you can choose the Viscosity you're looking for. Here is the link engineoil.api.org/Directory/EolcsSearch

They say LSPI can occur when you lug the engine. Can LSPI occur in automatic transmission cars?

[@dsport]

Absolutely. It's a condition that occurs in turbocharged direct-injection engines regardless of the gearbox.

Ouch! Sorry Leland. Hopefully this video series helped in any way. Let us know if you have any questions.

[@davidgruen7423]

Leland Holton explain please, my OCD is literally killing me, I was thinking over what kind of damage it could do to my engine and I had enough of it that I forced myself to test my theory on my own car (2007 Golf GTI). I tried to floor it in six gear at 5 mph, rev was around 500 rpm, engine knocked like crazy, I did it couple of times, and during the crazy test engine either just stalled or sped up over 5 mph that it no longer knocks, I plugged the scan tool and spark advance was like -25 degrees. Car worked fine, didn’t feel any difference after the beating. I wonder if anyone had actually broke their engine by low rev engine knock right then and there, or it was actually caused by carbon buildup, and other factors that gradually contributed to the failure. I already made an appointment with a psychologist today, don’t want to keep doing this to my car.

[@knightrider1545]

Which one? Theirs several

[@lamenamethefirst]

@@davidgruen7423 I can't figure out if a problem in my car is LSPI. Cause no one explains what it feels like. If I floor it in 2nd gear at low rpm, at a certain point it lurches forward violently a few times (like interrupted power delivery) and then it stabilises. This has happened a few times but the car still runs fine. Can't find any information to confirm if this is LSPI or something else.

@@lamenamethefirst that ain’t it, it’s common on manual cars, all you have to do is to push in the clutch a little when that happens, and make sure maf sensor is clean.
