Is New Engine Break In Procedure Still Necessary?

Right. I bet the CT5-V is a blast. They have been doing that on the gauge display for the corvette's for a long time. I have had 3 of them. The tune is no different and you can rev past the temporary guage cluster redline. It is still on the driver to follow the owner manual break in. This is proven by people who have broke in the engine on the dyno and started moding the cars from day one. And there is lots of people on the internet that claim they feel a difference after 500 miles, but there is no proof the tune changes.

I don't understand why anyone would resist the BASIC IDEA of a break-in.

First off, I can think of no downside, even if unnecessary.

Then, with human error and production tolerances being what they are, helping moving parts and friction points learn to get along sounds good to me.

Then, toss in the expense of purchase and repair.

I was wondering if the redline reduction was visual only in the guage cluster or actually enforced by the ECU, I didn't test the theory because I was following break-in procedure sincerely and kept it under 4,500 RPM anyways. In your experience with your Corvettes, did you feel any difference after the initial 500 miles?

I have been buying new vehicles for years (my first one was a 1975 Cheviolet Nova 2-door Custom with the 350 CID engine + a 4-barrel carburetor. I also owned Corvettes for 40+ years. I tend to buy what I want, then take care of them for some time.

I always drive my vehicles carefully, knowing I am responsible for maintenance and repairs. For years, I did a lot of my own vehicle maintenance, almost always using OEM parts.

My father was a maintenance machinist and insisted my brothers and I take care of things we owned. He was also insistent on maintenance and repairs, especially with our motor vehicles. His guidance stuck with me.

Taking care of motor vehicles, including a well-respected break-in period, just makes good sense.

I have read in GM Techline publications that some vehicles have a programmed RPM limit for the first 500 miles. I do not have a link to post.

This is me, having no argument with your post.

Our backgrounds match very well. Our attitudes match even better.

I drove my Camaros hard in the '70s, but took good care of them. They never failed me.

I did too.

My second car in high school, was a 1969 Camaro RS/SS convertible with the Z-11 Pace Car Replica package. Fun. Fun. Fun.

Years later, I bought a new 1997 Camaro Z-28 convertible, with the 30-th Anniversary package. It was a fun car but repurchased by GM because it was a lemon.
