    Hello everyone,,

    Turbo engine's reliability in long term

    So every new car and especially crossover SUVs are coming with Turbo charged engines.

    A friend of mine and a friend of my colleagues who we both consider car aficionado have advised me against a turbo charged engine for a long term use.
    My commute is very small, about 5km one way and my wife's is about 15km one way. Would turbo do better with my wife as it will get time to warm up a bit?

    I did a bit of my reading and it seems that turbos were quite unreliable a two decades ago but they seemed to have improved quite a bit, however have they improved enough to last 200-300k?

    What do you fine people of Reddit think?

    Thanks everyone, this was very enlightening!!!!

    My gsx had 211k miles befor I rebuilt the motor. And even then I just rebuilt it out of piece of mind. Turbo cars are not as scary as they seem, Especially stock.

    I honestly don't know where the taboo with turbo engines came from. Turbo diesels run until the turbo literally falls apart, old turbo cars that I can think of run just great. The problem comes with abuse, refusal to do maintenance, and refusal to use quality parts. Any engine will have problems if you neglect it. I personally think the attack on turbo engines is from NA or Supercharged only manufacturers trying to discredit the competition so you don't buy into the new turbo hotness. Kinda like the paper company did the hemp industry. (and I am the furthest thing from a pot smoker you'll ever meet)

    Short trips where the oil barely gets up to temp can be harsh on things...turbo engines are built with greater tolerances to the piston rings so there's a little more blow-by, plus the additional oil consumption factor of the turbocharger itself which consume a little oil by nature. If the oil stays cold the pressures will be higher and the ability to drain will be worse so the turbo will likely lose more oil slowly past the turbine sealing ring and into the exhaust system, eventually overloading the entire turbine side of the unit with coked oil and cause the turbo to fail. There's no real set limit or timeframe on that so all you can do is minimize short trips on cold engines to the best of your ability and you'll be fine.

    Ive logged 500k on turbo motors and I can share this. I only ever had to replace one. My maintenance is meticulous and fluids are full synthetic. My sister on the other hand loved to shut cars down hot. Run extended oil changes etc. She blew up turbos in two different cars back in the 80s and swore she would never own another turbo

    Ive driven my Galant VR-4 for some time as a daily and as long as you keep up the maintenance the car should last with no issues.

    Well I can tell you I have a 94 Eagle Talon TSI AWD with 274k on the odometer. While doing a valve job a few years back I elected to swap out to an 6 bolt engine so I'm actually on my second engine but the original turbo. I change the oil & filter every 4000 miles and let the engine idle for a minute before shutting it off. This seems to have worked for me all these years and have never had a problem with the turbo....
