Interesting GM 1.5T failure video

[wemay]

I keep it 3k/3m.

When people run the lowest price gas they can find and dont do adequate oil changes the results are pretty predictable. Many of these small engines are in budget cars that will never see anything close to what most BITOGERs think is a proper oil change. My Cruze had about 130k on it when I sold it to my son 2 1/2 yrs ago, no telling how many miles it has on it now. It is just about the easiest car ever to maintain.

Ammolab, time will tell with the 2.7 liter. It's almost double the size of the 1.5, so that's a plus. But I wouldn't be beatin on it with GM's reputation with their 4 bangers. Be nice to them. No red lining. Too much heat I would think. 5k OCI would help.

that would be very interesting information if you could somehow get it , you mention the dexos oils and oci, an example here would be take the average person from the older generation ,like my mother , who has a 2021 malibu , changes the oil when car tells them , which would / could be a 9000 mile oci, takes it to jiffy lube , and counter person askes what oil change would you like , conventional or the full synthetic which is xxx $ more , we can kind off fill in the rest of the story from there , i sold my 2016 malibu at 60k miles because of concerns of the lspi issues that i had heard of , that car ran like a swiss watch with m1 5w30 at 5k oci , same with my 2021, i now have an 2024 equinox with the same 1.5t,

the last part of your comment about a person would have to work pretty hard to find a non dexos oil these days , if you are diy mechanic or mainainence minded person , yes ,very true, but we probly only account for maybe 8-10 % or less of the general population out there , maybe around 92% out there , do you think the correct speced oil is in those vehicles ,and of a respectable oci
i very highly doubt it

Your 2024 Equinox has the LSD 1.5. These indeed have different pistons, rings and no potentially troublesome cam driven vacuum pump.

I've commented before that I don't believe any of these broken piston GM 1.5T's saw good maintenance. Regardless, I still stand by my belief that even Jiffy Loob uses Dexos oil. Even the least expensive oil you can get, Walmart Supertech is Dexos1 Gen3.

Good video. I think I'll keep my old non-GDI 4 bangers running as long as possible. These little things can't take the heat, shouldn't be in the kitchen. Poor / cheap designs coming out of the once Great Detroit. **** shame.

That’s because Detroit can’t make a I4 to compete with Japan(for the exception of Mitsu) or even HyunKia. The Ecotec series owes its existence to Daewoo and Opel, Ford’s Zetec was designed by Ford UK/Germany or they just merely rebranded Mazda’s I4. Mopar… well, it’s Mitsubishi really.

I don't think Detroit makes anything. Have you seen any photos of Detroit ? It's a Ghost town now. A run down ghetto. I think everything to produce a car is imported now.

Just off the top of my head I know theres still an engine plant (propulsion) in Pontiac and the 3.0L baby Duramax is built in Flint. I believe most people lump Southeast Michigan into "Detroit"

 

[50yr Street Mech]

Pontiac was one of my favorite models. Had many in the 70's and 80's. Grand Prix was my fav, then they had the Grand Am. The whole Detroit mess is a shame. Nothing was imported. All parts made in small nearby towns like Saginaw, and many other small towns around Detroit. But yes, I'm lumping into Southeast Michigan. 8 mile area. Still, the Big Three had the place locked up, until Nixon, Ford, and Reagan messed it all up with their " free trade" agreements. That was their death knell ......Cheap labor from foreign countries, and we're still paying the price for their mistakes.

I'm sure that combination of oil and fuel will make most engines happy for a long time, but I doubt anyone is buying a 1.5T GM wants to run premium fuel in it,

I get your point. These are pedestrian vehicles that should operate for a lifetime on today's everyday fuels and oils. However the incredible number of engine failures we see lately clearly point to highly stressed components giving up the ghost due to lack of adequate care.

Despite claims to the contrary, when one doubles the output of an engine, than asks it to propel a vehicle that would otherwise have an engine twice as large, long life requires good care. Unfortunately, this is not obvious to the average consumer.

We now have 4cyl 2.7Ltr Turbo engines in big and mid size pickups from GM. Do they have the problems of these 1.5 engines?

I've done internet study on the GM 2.7T, and as near as I can tell, it's pretty solid.

The power is there. Big boost numbers. The pistons have a cast iron crown built in, for stability. I don't expect to see any crushed ring lands, however these engines have a reputation for burning some oil.

My biggest concern is the complexity. They use cylinder deactivation, and multiple valve lift profiles. There is a LOT going on with this engine...maybe too much?

Here we go, cylinder deactivation to save gas. That was my 13' Pilot in " ECO" mode. Shut down cylinders on the highway. You wanna know what that did ???? Killed the CATS. I bypassed that S.O.B. at 75k. All 3 CATS failed at 100k. I waited too long.

Thanks. I have a new COLORADO 2.7T. 2000 miles down and all good. Plenty of power.
It would way out run, out pull my DAKOTA V8 5speed manual. The good old days are……
NOW!

Have fun ! Best of luck with it
