How To Prevent LSPI From Destroying Your Engine!

Low Speed Pre-Ignition (LSPI) is a type of detonation that can destroy direct injection engines, especially turbocharged DI engines. I this video, Lake Speed Jr explains 3 ways to prevent LSPI from destroying your engine.
Step 1 is using the correct type of oil. API SPI spec motor oils are formulated and tested to prevent LSPI.
Step 2 is keeping your fuel injectors clean. A Poly Ether Amine based fuel additive works the best at cleaning fuel injectors in Direct Injection engines.
Step 3 is letting your engine warm up before driving. LSPI occurs more frequently at low engine temperatures when the Moto oil is thicker. As the engine warms up and the oil thins out, the risk of LSPI goes down considerably.

Thank you again, I’m learning a lot through your videos. if this honest content keeps coming, I’m going to have no choice but to back this company. I’m already considering the dry assembly lube I seen on Danny’s video. #1 because I’m going to need it someday. And #2 also because this content does not seem like it’s trying to sell me anything. You you guys do let me know about products and services that you can offer, But you’re giving me the knowledge free and letting it up to me to make the choice. And in my book that honesty goes a whole lot further than you think. I’m not a wealthy man by any measure, and I usually research things for months if not years. But I really do feel like I can have some trust in a company if they’re this open with me. I don’t have a lot of money at all sir, but I know I might need that dry assembly lube someday. I really do believe it to be a good product. And for once (when I’m able to) I would like to purchase something from your company to personally invest a few dollars towards you. Thank you for the transparency openness and honesty.

The previous owner of my KEI truck didn't care for the engine much. Had carbon deposits cause pre-ignition in my truck. Mangled the connecting rod, shattered and melted the Conrod bearing. Barely limped home, but she did. Lake Speed Jr. has become my go to for information on keeping my new engine, the last one. Close to swapping the new engine in, and I'm going to do it ALL 💯% right.

@@TotalSeal any recommendations for a brand new Suzuki F8A crate engine that's been test run? Shipped from overseas of course. I'm assuming they didn't do a proper load break in.

[@arthurdeniziot2523]

Non direct-injection+turbocharged engines like the one in your key truck arent prone to LSPI. The failure of your engine was probably something else.

[@Funkydood]

How about Top Tier gasoline, Lake, will that make a difference, too?! Finally, what's your opinion on Berryman's B-12 Chemtool?!?!!!

[@kx454]

Lake, have you ever thought of producing/developing apex seals for Mazda's rotary (Wankel) engine? There is still a large market for apex seals as the engines are very popular, and are lacking good, consistent, aftermarket seal options. There are a handful of aftermarket seals on the market, but nothing is backed with the resources Total Seal has at their disposal. There is also room for improvement with their corner seal/side seal designs as well.

[@TotalSeal]

Thanks for the idea. That is not something we considered.

[@bigrich7026]

Redline assembly lube for oil soluble areas. Neo synthetic for press fits and seals. From .4hp to 4000hp on my resume. Having the proper tools is as important as the knowledge to use them. Patience to put something together and measure and take apart and put together to measure..over and over. Most don't have the patience..that's where the difference lies. Had to be perfect before it left my hands. Over 1000 motors built with no mechanical problems other than customers bad tunes and trying to out think us (swapping pistons without measuring ...ouch...) lol.

[@kx454]

Hello! Thanks for the video! Can you please tell me if the LSPI problem is common for Porsche V8 engines with an alusil cylinder block? My engines are also direct injection, but the manufacturer’s approvals for automotive oil only include SN. As far as I know, LSPI appears more often on modern small engines, right?

[@freeworld848]

Thank you sir for this amazing video. Bought a vehicle with M274 turbocharged inline 4 engine at over 50k miles. Treated with high PEA cleaner and started using only 93 octane top tier gas. Also just replaced the oil with Mobil 1 FS 0W-40 *SP* version. Planning to keep oil change intervals at every 3k miles. Is there anything else I can do further to prevent LSPI?

[@TotalSeal]

Excellent! Those are the right steps to take.

[@LA_Commander]

It seems like most all oils I've seen at the store are SP rated now, which is good since I have a TDI engine. However, what about my older port fuel injected car, how do I get oils that have the detergent levels we used to have in them?

[@richardusjames9780]

Based on your explanation, does 0w20 oil will have better lspi protection than 5w30? Due to oil thickness theory? Because it is thinner oil

[@lorinkramer5805]

The additive you mentioned, to the gas or oil? An additive name?

[@dingpongchi632]

Hi my MY 15 WRX FA 20 recommended to use SN grade oil for this direct injection engine in the user manual, should I switch to SP grade or stay what ever recommend by Subaru?

[@TotalSeal]

Switch to the SP spec oil. It is better than the SN for your application.

[@Dusty_Bottoms_]

How does API SP differ from Dexos rating?

[@aciddiver1978]

How often should i use liqui moly direct injection additive?

[@TotalSeal]

Every 3,000 miles works well

[@aciddiver1978]

My car opel insignia 2018 is recommended dexos1 gen2, api sn. Not sp. Is that wrong?

[@TotalSeal]

The Dexos 1 Gen 2 spec is actually a higher spec than API SP, so use the Dexos spec oil.

[@LujinCustom]

If my Toyota engine calls for 5w-30, can I run a thinner oil? 5w-20 or 0w-20 etc?

[@TotalSeal]

We would not recommend doing that without doing used oil analysis to make sure the thinner oil is not causing increased wear.

[@AashimGupta15]

What are some of the fuel additives that work with direct injection engines?

[@user-fl7uf9hz9v]

Is this just occurred in DI? What about indirect injection? Will it suffer from lspi as well?

[@TotalSeal]

Just DI engines or high compression racing engines.

[@bigrich7026]

Really not sure if this is important. We have never used zero gap rings in any, nhra,scca,Rolex,score,superkart and many other..motors..just saying. bore diameter doesn't affect ring tension? Bore diameter is not affected by temperature? Pistons measure the same cold and hot? So the ring touching the cylinder and the piston? Both of different materials at different sizes doesn't change ring tension?

[@TotalSeal]

This video is not about zero gap rings. It is strictly about direct injection engines from the factory or modified and how to prevent LSPI from occurring in those engines.

[@bigrich7026]

Not zero gap. Total seal which is gapless. Sorry I mixed terms that seem to mean the same mathematically. Im used to tuning end gap for my purposes. Think I'm in the wrong section..only injected motors I have ran are turbo diesels Cummins, Duramax and power stroke,.toyota gas motors and blown Donovan's running 90-100% nitromethane. Everything else has been carbed .None of which have ever done what your showing nor have any others in my life..not saying it doesn't happen..again I feel. Im in the wrong section..yes your explaining how it happens..I live in Pacific Northwest now..freezing temps..don't hear of this. Maybe not cold enough Your in Phoenix...? Christopher creek! ❤️

[@edogsx]

Hi and congratulations for the video! I know that the LSPI has been attributed to the calcium in the engine oil and that the new API SP class has reduced the calcium content by increasing the magnesium. Since both of these additives serve as an alkaline reserve, to reduce the risk of LSPI would it be correct to prefer oils with a low TBN value whit more frequent drainage intervals? Also because the use of "Long Life" oils in GDI engines with prolonged drainage intervals, favors the accumulation of petrol in the oil and therefore the LSPI ...

[@TotalSeal]

Thanks for the comment and question. There will be a video on the @SPEEDiagnostix channel regarding TBN and API SP oils soon.

[@edogsx]

@@TotalSeal Thanks for the answer, I had analyzed the oil of my Suzuki 1.4 turbo GDI and after 3200km it already contained 4.5% volatile fuel ... I use a MID SAPS (HC) 5w30 oil with a TBN of only 6.5. One thing I didn't understand is how the TAN went from 1.7 of new oil to 1.3 of used oil, maybe you have an explanation?

[@edogsx]

@@TotalSeal I have seen that even DRIVEN motor oils generally have quite low TBN values ​​compared to brands like AMSOIL which have very high TBN ...

[@themotoroilgeek]

@@edogsx that’s a high level of fuel dilution. In regards to the TAN change, that is within the error of the test method, so most likely it did not change.

[@TotalSeal]

@@edogsx Yes, the Driven products are typically lower Calcium formulations, which leads to that lower TBN value.

[@walterbrooks3539]

Do any brands of gasoline already have PEA already included?

[@TotalSeal]

Most Top Tier fuels have some PEA. The Shell V Power does have PEA

[@JHKCF]

@@TotalSeal. Is Shell V Power enough or should I still use additional additives? Just one treatment every 3k miles is sufficient? You don’t mention using proper octane, would that also contribute to pre ignition?

[@themotoroilgeek]

@@JHKCF The V Power fuel is great stuff. Using a bottle of PEA based detergent additive once a year won't hurt. It's a little extra insurance.
