BREAKING! Why These New Car Engines Are IMPLODING!

[@22099dscott]

Except no port fuel injection or and gasoline fuel injection system has ever premixed air and fuel prior to injection. And MOST people put the cheapest fuel in their vehicle. When you shut your hot engine off it leaves a layer of oil on the cylinder wall that does not drain away over night or even over weeks. If what he is claiming were true ALL engined would have this issue and they simply don't.

[@frststrykr]

The problem isnt DGFI, its the LV motor oil combined with lower ring tension. Use 5w30 in 5w20 motors, 5w40 in 5w30 motors and 0w30 in 0w20 motors and change your oil every 5k miles

Seems to be the way

[@davidanderson8469]

I recently bought a 2023 Honda Passport with the V-6 which has been around forever. I do wish it did not have DI but 5K oil changes with synthetic should help a bunch. There's a Passport offroad site where the owner took the vehicle in for the 100K service including valve adjustment. The mechanic showed the valves were quite clean and needed nothing. It had 5K synthetic oil changes and the mechanic swore by 5-30 in them for longevity.

[@wickertwm]

The fuel dilution has more to do with the design of the injector or the design of the head where the injector is mounted. It can result in more fuel being sprayed onto the cylinder wall. This fuel can bypass the low tension rings getting into the oil. Oil does not mix well with fuel and can cause the sludge that blocks oil passages and causes engine failure.

[@ECPP]

Totally right. Also once the process starts, it just continues to add and compound the issued until a failure is imminent.

Why pcv valve?

[@jamesmedina2062]

It is not one size fits all. Every part has its lifetime. Take the spark plugs. Old style lasted 10k but Iridium changed that. Which coolant it is affects its lifetime as does the engine metallurgy. PCV valves and PCV system design all vary as well. Even pistons are not all the same because of rings type, cylinder machining, concentricity, tolerances, cooling from water, cooling with oil, and how it gets driven and what climate it is in. Just too many variables.

When my wife chose her 2023 Kia Soul in I knew what we were getting into. 😆 Then again you couldn't find a car on a Toyota or Honda lot and she needed one to replace the one she lost to a deer accident in 2022. I'm not going to get into the used offerings at the time in our area, needless to say for $23k it wasn't a lot of money in terms of what was out there used at the time, mostly rust buckets from New England. That 2.0L "Nu" engine is really noisy on cold start up, same as the one in the Forte. Interestingly enough I found a post online where someone switched to Pennzoil Ultra Platinum and it helped quiet down the clatter (same viscosity) and I tried it so I switched from Mobil1 to PUP and it starts up a little quieter now. But that engine you need to change the oil every 3k miles, forget about 5k or 7.5k. Right now it's got 20k on the odo and doesn't burn any oil or at least none that I can see checking the dipstick once a week. I also only use 91 or 93 octane, the compression ratio on these is 12.5:1 and so I noticed it runs smoother with the higher octane. Sometimes I think the car shut off on me being a Kia because it's so quiet and the steering wheel has hardly any vibrations like you'd associate with a car of this price point. So I have to check the tach to make sure it didn't shut off, being a Kia I'm always half expecting it to shut off on me, I don't know why. The only thing that broke was the master window switch, we went through 2 of them because the first replacement was also bad from factory. I just need it to hold for 10 years at least, once the power train warranty runs out then I'll be happy I got 10 years out of it but who really knows, might be more or less. I intend on doing the CVT service every 30k miles, I'm not following the owner's manual there which is lifetime fluid, or under "severe service" schedule it says to flush the CVT fluid every 56k miles which I thought was an odd number.

[@RichPober]

Excellent explanation. Direct injection into the combustion causing fuel dilution of the engine oil is a big problem for all car manufacturers. However, the car manufacturers are not honouring their car warranties, and are instead blaming the car owners for not maintaining their cars adequately. The issue is that the manufacturers have extended their maintenance intervals to far beyond what they should be for a direct injection engine. These DI engines need far more frequent oil changes. Jaguars are well known for their engines failing due fuel dilution of the engine oil, requiring a full engine replacement.

Toyota have 2 types of injection on some of their cars, they combine the 'OLD' and the 'NEW', hopefully the OLD type partially cleans the back of the valves, perhaps a partial flow of, say kerosine could be fed by an injector into the inlet system to of a diesel try and clean the valves.

I'm expecting delivery of Corolla Cross equipped with M20A-FXS 2 liter engine and the fact that you smell gasoline in oil within 3K kms sounds alarming.. do you use the car exclusively for commuting/short trips into town or highway use ?? thanks in advance for your reply

[@MickyMouseLimited]

This was finally a good video. Basically all new engines needs a catch can and a lot more oil changes plus often high load driving conditions in order to evaporate the gasoline from the oil. If you get your oil up to tempreture you will evaporate the lighter fraction the gasoline and unfortunately often oil changes would be required . We do have a sky active Mazda that is only direct injected but it is NA so we never had any issues only do regular oil changes and run the car hard on the high way. But the low power NA engine doesn’t suffer from a lot of blow by and crankcase pressure making it last a lot longer . So the major problem is not so much just the direct injection but also the firing pressure and the amount of hp per L of displacement. What use to be a norm only for sports cars now it is in daily driver. Most of this failures did exist before but they were in sports cars so the general public never felt it for example rally cars with turbo engines were making from 150 to 200 hp per L of displacement now even every day cars are having the same power per L of displacement all this power will lead to problems and this is the reality.

Let’s say you put in the best gas and more then regular oil changes will this help for the longevity?

[@Technocrat.]

Just had an idea for a new piston crank system. You know how the piston Rams in and out which causes huge gforces on the piston, crank shaft and bearings. Why not have a off set piston shaft, meaning it goes up at a angle, when hits end, there's a mild rotation at the piston shaft and rod where'd piston rod ends up at the other side of the piston and comes back down, same happens at bottom of piston. So basically the piston rod is working at an elongated elliptical rotation, less sharp stop and both ends on piston travel. What do you think, do you even get the picture what I'm trying to say lol.😂?

[@Blue-moon12]

I have two Direct Injection engine vehicles. You have to use WOT now and again, regular oil changes are a must. Also an oil catch can and intake clean will help. One of my vehicles has 200k kms (2018 G80 sport) and no issues.

[@ECPP]

The old "Italian Tuneup". Works

[@JasPlun]

One issue is lack of oil changes. People try to follow the manufacturer recommendations which are not good enough for turbo engines. The turbos use oil to cool and it cooks the oil really bad. If you have a turbo charged engine I would be doing oil changes every 3000-3500 miles even with synthetic oil. Naturally aspirated engines yeah every 5k is fine, but not for turbo charged engines. Also make sure you use oil with SN on the certification to reduce chances of instant catastrophic failure when starting a cold engine. Dave's Auto Center has a video on that problem. Glad you covered the LSPI issues it is sad some folks do not know they could blow their engine just starting it when cold outside. Excess fuel getting past the rings is usually not a problem for people that have longer commutes it gets burned out, but people with short commutes its a problem it never has time to burn off. Well done Mark:P

[@IndyAvocadoKid]

FWIW, turbos on economy cars seems like a bad idea, any money saved from fuel economy improvement will go toward turbo repair costs later on🤔🙄🤨

[@Sanitytrain]

Use ONLY Top Tier gasoline-look on the pump for label, This will keep injectors clean long term. Change the oil every 6 months or 5k miles. Try not to run engine for very short trips. It needs to be warmed up fully for maybe 15 minutes at least once per week to keep oil and crankcase free of moisture. Warm the engine up for 5+ minutes after coolant temp hits running temp before loading the engine. Cool down the turbo and bearings for 2 minutes minimum after running up a hill, highway, or any driving that loads the engine signifiganlty. . Change the coolant maybe every 5-6 years. Change the trans fluid every 40-50k miles or every 6 years. Look at the maintenance shedule before following any of this advice! Some types of vehicle need even more stringent care! The above is only what I do after a many years of learning. Read your manual! 10k oil changes are a very bad idea in my opinion.

[@klesmer]

[@Lurch-Bot]

Direct injection was first used on diesels. The thing about using it with gasoline is that you have far less margin for error. You get some carbon buildup, it starts glowing red hot around the edges and the next thing you know, you're pre-igniting and that's how you break an engine. I suggest if you have a late model car that you put a can of Sea Foam in the tank once a month to keep that carbon buildup down. You can also add some to your oil with every oil change to help resist sludge buildup. I get 23mpg around town from my 2001 Jetta VR6 with a manual transmission. Regular old port injection. In a 2.8l 6 cylinder motor. Running the A/C. Was considered an ultra low emissions vehicle when new. State of the art. The bar has moved since then but it still isn't bad by modern standards. It has even had a stage 1 tune. Not a lot of VR6s still on the road because people didn't take care of them. Cheaped out on fuel. Used the wrong oil to save a couple of bucks. It is critical to follow manufacturer specs. Most of the Mk IVs you see on the road have the bog standard old school 2l NA I4. You can run regular oil in them. You can run 87 octane fuel. That's what those engines were designed for. But if you do it with the turbo 1.8 or VR6, you are destroying your engine. You never want to use lower octane rated fuel than specified. Even if the system can compensate to avoid knock, you're running at retarded timing, getting fouling, poor fuel economy and reduced power. I absolutely loathe how modern automatic transmissions tend to be tuned. There's a lot of engine lugging going on which is bad for the engine and really not great for fuel economy or emissions when you put your foot down and the transmission doesn't downshift. The low speed running is great for mileage when you are cruising on the freeway but the moment you need to accelerate or add power while going up a hill, the transmission needs to downshift but it doesn't. Or you put your foot way into it and it downshifts too much, leaving your motor screaming away at 6,000 RPM. Sad that the manual transmission is going away. I can handle an 8 speed manual without doing a money shift. I learned to drive a semi when I was younger, though I never actually drove one for a job because I ended up going into aviation. Most people in the US can't even handle a three on the tree these days. Automatic transmissions have always been a crapshow. But even more so today. Back when I was driving cars with older 4 speed automatics, you could just set it on 3 for around town and the cars were reasonably responsive. Before they became electronic, you could just tweak your throttle valve to alter the shift points and make the transmission work more aggressively, downshifting sooner and upshifting later. With practice, you could learn how to precisely manipulate the throttle valve to make the transmission do what you wanted, when you wanted. Modern automatics have 6, 7, 8 or even 9 speeds and they can't manage to make effective use of them. IDK how TF Elon Musk thinks he's going to make his driverless future happen when they can't even use modern technology to make an automatic transmission even the pickiest manual snob couldn't fault. A computer should be able to shift more accurately than I do, as someone who learned on a manual, still drives a manual and has a quarter million miles under their belt, but they simply can't figure out how to program them right and don't use enough data points to figure it out. By now, a car should know if you're going up a friggin hill and shift accordingly🤦‍♂🤡 Thanks to the proliferation of smartphones, the necessary sensors are cheap and readily available.

As far as direct injection goes, it allows the injection event to happen independent of the valve timing which why the manufacturers dont want to abandon it. Also you could have more than one injection event during the combustion cycle to shape what whats happening in the cyclinder.

They need to move the direct injection above the intake valves shoot fuel onto the valve and then gets sucked in, this would keep the valves clean.

Throttle body injection was even better than port injection, since the entirety of the intake system was getting cleaned with the fuel. No carbon deposits anywhere in the intake system.

[@chriskappert1365]

How about disconnecting the carterventilation and just let the gasses out in the open , just as the old days ? You will get a lot less carbon and deposits . Or place an oildivider between the rockercover and intake manifold , so cleaned air commes in ?

[@turbotrana]

I used to rip apart carbed engines 30 to 40 years ago and inlet valves were caked up and piston rings commonly stuck with carbon. We used to scrape the carbon from behind the rings. So even the carburettor fuel was not enough to get the PCV oil burnt with the fuel. Port fuel injection totally solved that and valves and rings would stay clean as the injector spray was enough to mix the PCV oil into the combustion mix. Come direct injection the oil cant mix in with combustion easy, ends up caking everywhere and eventually will take out the engine. Even valve seat areas suffer from the carbon.

[@dooganlinn7578]

Excellent advise everyone should follow. 0w motor oils take a beating.

Forced induction like Turbos and superchargers are a bigger cause of engine failures than direct injection. The added heat and stresses that comes with forced induction, especially in small engines that are pushed hard to develop horsepower wears out engines prematurely.

Smaller engines being forced to work harder. Higher mechanical speeds increase stress/fatigue failure.

[@23Piccolina]

Wouldn't using high quality gasoline, such as Chevron with Techron help these engine issues? I have added a bottle of Techron monthly to my gas tank of my '08 Mercedes V8 and it runs great. Of course I use Chevron supreme gasoline as well. My engine has 62k miles and no issues to date.

[@paulparsons3101]

Great Vlog again Mark.

[@ECPP]

Thanks 👍

[@jasoneyes01]

We have been programmed that engine flushing is a bad idea. I have never in my life seen more stuck rings, cylinder scoring, sludge, and carbon fouled engines in my life. All this can be eliminated with 1 or 2 cups of diesel added to crankcase and run for 20 minutes before changing oil. These modern crankcase ventilation systems have turned your engine into a garbage furnace. Changing your oil isn’t enough to stop the destruction.

[@ECPP]

Yes too much “holding it all in” causes a lot of problems

[@mmone1178]

Thanks Soo much for sharing. Soo informative 🙌🏾🙌🏾

[@ECPP]

You are welcome

Fuel is important even in direct injection engines. Using "Top Teir Fuel" with the correct Octane rating will help. These fuels are blended with additives to clean the upper top of the piston and into the rings somewhat. Cheap fuels can be 91 octane but do not provide the detergent additives t the same degree. Always use "Top Tier Fuels". Shell has the Top Tier Fuel posted on their pumps. See The Oil Geek for the chemistry about oils and the use of quality fuel to prevent Low Speed Pre-Ignition. Some times you do get what you pay for.

[@ECPP]

True, correct octane is always important and not having a quality. grade can stil cause engine damage in other ways. Always important .

[@MikeyD8632]

Toyotas D4S is reliable. They've been using it for around a decade now. More OEM'S need to care more about this issue and not writing it off to expected maintenance. It's sad in 24 manufacturers still use GDI only

[@ECPP]

Ypu are right Mikey, I agree, the dual system is such a great design and not sure why many don't go that route. Well actually it always comes down to cost. If they all did it right, there would be much fewer problems in the biz.

[@SimplelifeCo]

Thin oil, direct injection and to top it off a turbo.

[@ECPP]

Great point!

[@jaguar7051]

Yes, very important Oil and specifications you showing up. Engine Oil has to withstand all stress during the combustion, plus burnet very clear means minimum ash. Direct injection Gas Engines are the same as Diesel Direct injected only lower compression with spark ignition and gasoline Today new engines need the same engine Oil with the same specifications as Diesel Blutec Engines. Have very modern Engine Oils up to 5W40 with those specifications. I use in my GLS350d 5W40 MOTUL - LIQUI MOLY - Now I use PENTOSIN - I get a better price. Those economic fuel-saving engine Oils damage the Valve Train is too light. 5W40 engine Oil is for today's cars with specifications that say low ash MB 229.52 (60/71) ( Euro 6 specifications and soon Euro 7 specs) Those other 5W40 oils are very different from those 5W40 standard or old fashion oils. Look on the DATA SHEET - you going to see Viscosity at 100C max 13.5 and a viscosity index of 200 or a little higher which is very important. Old fashion 5W40 Viscosity at 100C 14.5 or even higher 17 - viscosity index 120 The viscosity index is very important for higher oil quality ( not affected by high and low temperatures to be degraded during the cycle of use. In my BMW I use the same engine OIL 5W40 PENTOSIN Viscosity at 100C 13.5 viscosity index is 195 - low ash burning LIQUI MOLY 5W30 4200 eng oil has one of the best viscosity at 100C 12.2 and a viscosity index of 200 Go to Google search for all kinds of engine Oils = DATA SHEET observe Viscosity at 100C and Viscosity index the highest - garbage oils have very low visc. index.

[@ECPP]

Some very good information and I appreciate you providing this as it may help other car owners. Sounds like you have done your research. Cheers

[@jaguar7051]

@@ECPP Engine Oils I divide new and Old styles or parameters. Good mother oils up to 5W40 low ash ( The most new norms) Viscosity at 100C is not higher than 13.5 ( 13 - 12.9 - 13.2) A very important viscosity index up over 200, if can find one, is the best. LIQUI MOLY 5W30 4200 model is one of the best that we can get in Canada Viscosity at 100C is 12.2 Viscosity index of 200. Oils with higher viscosity and older style going to kill the engine too. Those modern engines are built with lubricated channels with very small diameters for very light engine oils to hold pressure in the Lub system. When we use old-style oil 5W40 or 10W40 reducing oil flow in the lub system damages the engine. Those very light engine Oils as 0W20 OW16 Viscosity at 100C 7.5 up to 10 and an index of 130. For that reason killing the engines. Lab Fuel economy test is for how much can save = during a 1 year can save 2 or 3 liters of fuel. This is true - governments need those numbers for their propaganda. Why is no one word about why engines can't last? Why is the Government not saying long-lasting engines are less polluting?

[@thewaywardgrape3838]

Buy a pre-2015 car outright. Buy a second one as a spare. That's what I've done and it's cost me £5k for both cars. Far cheaper than renting a car for 4 years, only to be far worse off!

[@NomadicCratic]

This video was spot on. I wish manufactures would do away with the turbocharged engines. Over a period of time, the turbo itself will need to be replaced. My next vehicle with either be a Toyota or Tesla.

[@erwin734]

To do that would require manufacturer to be honest and go back to 1990 where 330i means 3.0 six not a retarded 2 liter four. Let the factories close so the greedy bastards pay the price.

[@Kytes93]

the problem is not the DIRECT INJECTION in itself, it's the EGR valves installed on ALL cars who meet Euro-6 emission normative. The EGR valve takes part of exhaust gasses and redirects them into intake manifold to cool down the combustion chamber and reduce NOx gasses and because of this recirculation system it builds carbon and oil on your intake valves, but since there's no more port injection, nothing else can clean your intake valves. The oil dilution is cause by OPF/GPF filters, in order them to operate they need to be in a certain range of temperature like on diesels, so in order for them to regenerate aka all the PM10 soot burn down to PM2, the engine shoots a little bit of gasoline into the chamber and leaves with gasses to then do the post ignition into your OPF filter. Obviously not all gasoline will leave the chamber and a small amount will dilute with the oil but overtime it will accumulate. So change your oil every 5k miles because gas is a solvent and it will wash your cylinders from oil.

[@tomaszbudnik521]

There is simple solution used by Lexus - direct injection and port injection in same engine. This way you can get best from both solutions.

[@lelandpodoll9628]

Toyota uses both Direct Injection and Port Injection to alleviate the carbon build up. The Port injection is for specific conditions.

[@shafly67]

Apparently another big problem is they install valves upside down

[@ECPP]

Nice

[@DigitallFlesh]

Toyota uses direct injection with port injection to clean the top of the valves. This is what all manufacturers should do, but don't.

[@BriansRCStuff]

132,000 miles on my 2011 Audi A4 direct injected 2.0t. It runs great and I never have had any issues with carbon (other than the defective piston rings that plagued several years of these cars). Oil changes every 7000 to 9000 miles with Mobil 1 0w40 and top tier fuel. Also, I do not sit there like an idiot and idle my car for long periods of time. The car runs great and feels similar to when it was new. That is not to say it did not have a ton of problems… New pistons, piston rings, and turbo charger at 65,000 miles and a new timing chain tensioner at the same time.😂

[@jrfarawayfrom2016]

WMI should be factory installed by now to prevent this, but too many people would poison themselves or catch something on fire 😬

[@randycrager4074]

Why I stick with my old beaters! I have three brothers that are Mechanics and saw the problems on the rise. I know of a man that his motor blew on the way home and he even had a dealership guy in the car with him. He ended up having to litigate with an attorney over the deal. New cars are GARBAGE! I have an 85 VW Jetta Diesel that runs and drives like I just bought it.

[@tellucas]

I seriously doubt the manufacturer didn't see these issues during testing. In any case they want these small engines to feel big to the driver so these small turbos are set up to give a lot boost low in the rev range for that "flat" torque curve beginning below 2000 rpm.

[@reiisthebestgirl]

You absolutely saw carbon fouling in the intake due mandated EGR systems on systems that didn't do EGR by adjusting valve overlap.

[@briannielsen7176]

I would say vehicles that were made between 1987-2010 were the right combination of technology and durability. The previous 10 years before they sucked since the auto manufacturers were trying to adapt. After that in 2011 they were try to adapt again causing all kinds of issues. I sure miss these vehicles made between 1987-2010. Another advantage of those vehicles is you could still work on them and they didn't cost a fortune to buy. I would also add that pre 1974 vehicles were also nice since they had much horsepower and not all the epa nonsense. This is when vehicles were absolutely beautiful with design and style. In fact they had women in swimsuits that advertised them. You look at the modern day car they look boring and cheap like someone without any style putting them together. There is no more sexiness about most of these vehicles just efficiency.

[@ericscottstevens]

I would say the gold standard for Toyota was 1998-2010. Then they decided to go market share and build a lot more cheaper quality cars.

[@guruofendtimes819]

First gen highlander made in Japan.

[@briannielsen7176]

@guruofendtimes819 Good example I had a 2012 Ford Focus. At 95k I started having problems with the stupid transmission. I had these problems until I sold it with 140k. The previous models 2010 and earlier had the normal old school transmission and with general maintenance you could easily get 250k on that vehicle. The sad thing is the dealership only would replace the clutch once since I got it in just under 100k and then the computer at 125k. They said it was my baby after that. At 140 it started doing the jerking nonsense so I took the grounds off since it's primarily electric controlled and cleaned them out new dielectric grease on and that worked for 5 thousand miles until it did it again and then I sold it.

[@overbuiltautomotive1299]

change oil 4k max miles not 8k plus only use top shelf valvoline or ?

[@ECPP]

More ferquent changes is best as oil is chep but engines are not

Most nowadays cars are made with mass production in mind, not maintenance/service.

Never been a fan of these flea-sized turbo engines. They may be quicker than their naturally aspirated counterparts, but many of them will fail much quicker too.

[@roryscottbrown]

Many of the Ford Engines are dual injection now. The Mustang 5.0 has been dual injection since 2018, previously port injection only. The Mustang 2.3 Turbo since 2015 was direct injection only. The new 2.3 Turbo in the 2024 Mustang is dual injection.

[@ZX81-c3u]

Mark, Thank you for sharing the video! I understand that Toyota uses a combination of dual-port and direct injection technology to address carbon buildup issues. If this concept truly works as intended, I wonder why manufacturers like Mercedes haven’t adopted a similar approach. Do you have any insights on this?

[@dallasdorrington7449]

35 year old nissan straight 6 MPI 1.3 million miles and still runs great. Back then Nissan said as long as you service the engine when it needs it that engine will continue to run forever almost. They were used as taxis back then and 1.5m to 2.5million miles was normal for these engines. It's what was called a Non Stressed engine and because of this they could run up millions of miles without any major issues. You won't ever see a modern engine do that. Most are lucky to see 100,000 miles before catastrophic engine failures.

[@kurtjammer9568]

Not all engines use oil..my 2018 maserati levante doesnt use a drop between oil changes and has very little dilution and blowby.and i run it fairly hard..actually my toyota engi e uses more.strangely..so i guess it varies .

[@ECPP]

Yes it certainly Does vary and Many use almost none. It’s a total design with DI being a major Contributor

[@oildrag]

My 1998 Honda Accord Coupe 2.0 VTECH manual ESI burns zero oil, no leaks, goes well, everything still works perfectly, remarkably no rust ! So why change it for anything else ? 👍🇬🇧

[@RobsNeighbor]

And why? Nothing is working except the few that were so great, so that didnt work... Thank you for sharing the drawbacks with all the waste do not help. Love the channel

[@ECPP]

You're welcome! Thanks for the watch. Cheers

[@PandiKristo]

Hey people i take out spark plugs and put in carbon clean directly in cylinder and start engine. Everything clean. And in manifold i add carbon clean.

[@sabodebol3836]

I've been dealing with that was a 2014 Tiguan was misfiring five different codes and I know it's because of the carbon buildup on the valves.

[@peterwait641]

Long service oil may stay in grade but combustion by products and carbon in suspension will cause wear. Stop start tech will increase oil dilution and short journeys . Turbo charging small engines increases heat stress so will need more oil changes. 5 k oil changes are best for long engine life.

[@glennoropeza3545]

it's that way by design so you're forced to trade-in! It's a racket!!

[@claytonhughes5256]

I drive an 04 odyssey, paid a grand for it. 172 k miles. Other car is a grand marquis. Paid 2200 for it. Put about 2 grand in parts on both to get them up to speed.

[@richardjones7386]

It’s not injection issues. Look to oil service intervals.

[@aciddiver1978]

2 last cars i had, approx same weight, one of them gdi and one port injected. The port injected use 15% less fuel, so are there any pros at all for gdis? I think not. Engines should never be downsized with turbo, they will live under constant enormous stress.

[@lelandpodoll9628]

Oil consumption is caused by extended oil change intervals

[@vanhasydan4754]

One part of the carbon fouling in DI engines is the design of the EGR. With nothing to wash the condensed oil vapor off the valves and runners, your designing the engine to fail after a too short life. Yes, I know I am oversimplifying but those with sufficient engine knowledge will understand.

[@classiccorvettesmusclecars5846]

It’s why I luv my Corvette LS engine..They run forever…GM went to direct injection & cylinder deactivation in the LT engines in 2014…No thanks
