Oh, and I can't help but add that if all the ecoboosts start breaking down at 150,000 miles Steve Hubert should win a medal. Or an engineering job. Heh heh
I don't deserve a metal, but here are the facts:
1.
) Name me one turbocharged gasoline engine that you've ever owned and driven past 150k miles. You've probably never even owned one before. Partially do the fact that the few that have been used over here in the States we not known for their stellar low maintenance or longevity. Japanese and Scandanavian car markers like Subaru and Volvo
(both known for low maintenance and long-lasting autos
) have been putting turbocharged gasoline engines in cars for decades. It's hard to find a Subaru or Volvo Turbocharged car that's still running at 150k miles on the odometer.
2.
) Turbo's put a lot of stress on engine internals and they tend to really cook engine oil. Not only cook it, but also shear the snot out of it. As a result, you end up with even thinner oiler that today's truck demand due to GPM regulations
(see CAFE restrictions
). US government demands thinner oil in today's car to squeeze out better gas mileage. Don't believe me? Your Honda Accord specs for 0w20 in the USA, but the owner's manual in Europe says a 30 or even a 40 weight is recommended. Same exact engine.
3.
) In a turbocharged gasoline engine you end up with highly oxidized engine oil that has a high load of acid byproducts and a very low TBN very quickly
(the ability of an oil to neutralize acids
). The end result is a sludgy mess. Sludge and particulate matter in a turbo engine = problems. Turbo lines get plugged, screens get plugged, bearing fail due to oil starvation, etc. etc. Couple all these oil facts to the fact that manufacturers are telling everyone to extend their OCI's
(oil change intervals
) even further
(in an effort to "lower overall ownership costs
) and you will end up with a ton of Ecoboost failure in the near future.
Does anyone on here know of an Ecoboost with 150k-200k miles on it yet? I'd be curious to hear about it and the maintenance that was required to get it to that point.
