If I had to guess it has to do with government regulation of fuel standards and emissions. I don't think its a cost deal as many of the exotics that would also benefit don't offer it. It obviously not just a GM thing.

One being better than the other comes down to the use case IMO. It's proven that ethanol helps resist detonation in turbocharged and supercharged cars that tend to run hot especially on the intake charge temperatures. Ethanol doesn't have as many BTUs so it takes more fuel, thus cooling the...

Infrequently would be several months and is much more geared towards wet weather climates as the ethanol gas takes in moisture. For something like my lawn mower here in Oregon, I run ethanol the majority of the summer and then switch the last month or so I know I'm going to be mowing to the...

Use the 93. In a turbo or supercharged car like a Blackwing the ethanol helps somewhat resist detonation, the higher the ethanol content the more resistant to detonation. the more timing you can put to it. Non ethanol will have more BTUs though. The non ethanol should theoretically get better...

I wouldn't be surprised if both used the exact same bearings.

100% agree. If Corsa had a square/carbon or at least square option it would already be on my car.

They are not all built by the same person. Each motor is built by one single person. Just to clarify.

No reason to believe the LT4 in this car would be anymore or less reliable. The whole "stay away" garbage is well overblown. The LT4 are all and have been built in the same plant and are/have been assembled by one person no matter if it went into a Z06, CTS-V, Blackwing, ZL1 or Escalade V. In...

Was the Z06 reliable?

In your original poster it made it sound like you pulled the plug? Have you done anything or was all work completed by Cadillac?

What did the rest of the plugs look like?

Windows seem high but the PPF seems ok. $300 for clay and polish seems incredibly low as it should take several hours if not a majority of a day to really do a good clay, decontamination and polish.

I don't think window tint makes much difference. Get it in the darkness you want and the color you want as some tint has a hazy/blue color to it. 3M or Xpel for the PPF. As for ceramic, they seem to be about the same for the 10 year stuff. Ceramic all comes down to the prep and polish before...

After taking delivery of my 2025 CT5 Blackwing a couple of weeks ago I've noticed that at freeway speeds the vertical/look ahead or projection distance of my headlights is very poor. At 70ish miles an hour I'm lucky to have two lane hash marks visible in front of me. Even high beams don't...

While I don't have any specific information to share on your particular tow vehicle there are some general things to look out for and pay attention to. It's a good idea to keep eye on the transmission temp and keep it under 220. Carefully inspect trailer tires as a dead/blown tire on a...
