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.

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.

Since 2019, I've been using snplus and sp grade engine oil, but I've had constant lspi and engine oil reduction, and as a result I've replaced short block of the engine. In my experience, engine oil doesn't do much to prevent lspi. You should use fuel high octane gasoline and clean the intake valve and combustion chamber regularly

[@solardiver7]

You talked about fuel additives. I have only used Top Tier premium (Shell 93 octane) in my car (Mazda MX-5 direct injection) . Would I need a fuel additive? I also use Mobil 1 synthetic SP.

[@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.

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.

Best explanation of all; i was in the wrong, i thought that cold oil would be scraped down , better,by being thicker, but you say otherwise, you say that thin oil,hot oil, is scraped down better?

[@jamesbuttery3862]

No it's easier to scrape it down the cylinder wall if it's thin, and hot. The less mass of oil the lighter it will be, the easier it will be for those low tension rings to scrape it down the cylinder wall.

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

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?

[@ArtGomez-g4f]

You do not want to put the engine under any load right after you start it. For one there us more blow by due to lack of piston expansion and the fuel system is way rich at this moment plus you want to accelerate and this requires more fuel than just idling. There is also a lot less pressure above the piston if all you are asking is for the piston to make it around until the next power stroke.

[@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?

[@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.

[@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.

[@truracer20]

For 1 your Toyota engine isn't direct injection, for 2 your owners manual will list the oil grade the engine requires. If you have an oil cap that calls for 5w30 then use 5w30, if the cap calls for 0w20 then only use 0w20. THE#1 RULE is only use high quality full synthetic and keep it topped up and changed regularly. Oil isn't only for lubrication, it also carries away HEAT, so do your engine a favor and let it idle for a couple of minutes after any had driving before shutting it off. Toyota engines that receive timely and proper maintenance have no problem going 300K plus miles with the recommended oil. Synthetic blends WILL cause sludge, that sludge WILL plug the top end oiling circuit that oils (and cools) the valve train as well as the timing chain, that sludge WILL FORM inside of the VVT camshaft phasers as well as at the filter screen for the VVT oil control solenoids which feed the VVT camshaft phasers (on VVTi 4 cylinder engines), that sludge WILL FORM in the oil control ring groove of the pistons and WILL cause irreversible cylinder wall damage, that sludge WILL FORM inside of piston oil squirter's leading to premature cylinder wall wear as well as exacerbating the sludge formation in the piston ring grooves ( the piston squirter's not only lubricate the cylinder wall but they also COOL the pistons. Conventional oils and synthetic blends are more prone to coking. Coking happens when oil remains on or in hot components after the engine is shut off, it chars and becomes ashy similar to burnt facts on baking dishes and grills. It doesn't just wash off, it accumulates. Modern engines have more latent heat when they are shut off, they have much closer tolerances, and they are using motor oil as a hydraulic oil to an exponentially higher degree than old school hydraulic lifters.

[@TotalSeal]

Thanks!

[@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.

@@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.

Further proving that gasoline direct injection is not a good idea. Direct injection works very well for diesel fuel because diesel fuel has a very different flashpoint than gasoline. Trying to make a gasoline engine work like a diesel engine so far has been a miserable failure. Also trying to get better gas mileage by loosening up the piston rings also is a bad idea. Time for the auto manufacturers start pushing back against the Federal governments unnecessary and unrealistic mandates.
