Some ATS-V onwers use pour-in engine oil additives, such as "Sea Foam", "STP", "Lucas Oil Stabilizer" and so forth. If that's you, watch this video done by Certified Lubrication Specialist, Lake Speed Jr. on his "Oil Geek" YouTube channel. Now...change your oil to get all that s**t out of...

I know, right! 🙃

Lurch then Crunch. My ATS-V Coupe was in a minor but what turned out a very expensive collision. A week before Christmas I was in a Valero station. Each island had three pumps. The pump on one end was in use so I used the pump on the other end. I was holding the valve wide open and looking away...

So this was testing on an engine dyno not flow testing?

I just noticed this post is in the wrong forum. Well...duh My bad.

What about the set of ported LF4 heads was problematic?

When we had "Pearl", the only problems we had with the 8L90 were 1) a sometimes harsh 1-2 shift at light throttle and while still warming up. It was a minor annoyance and 2) failure of the trans temp sensor which required warranty replacement of the 8L90s entire internal wiring harness. Our...

All's Well that Ends Badly Once again, it's been a long time since I've posted here, but it's time for an update. Unfortunately, the news is not good. Back in early July, my Wife, the Fairest Sandra the Red, came home from work saying that when she started her ATS-V sedan, "Pearl," prior to...

Finally! Our '16 Sedan, "Pearl, is back on the road with its third engine. My Wife, the Fairest Sandra the Red, has about 100 miles on it with no problems and she's happy to have her car back after a couple of months parked on the dealer's back lot waiting for parts. With this engine...

Another New Engine Ok, now...let's check-in on my other ATS-V, the early-'16 four-door my Wife, the Fairest Sandra the Red, drives. That's been another warranty problem-child. Like the Blue Bullet, my six-speed Coupe, it had to have it's engine replaced due to the oil smoke after cold start...

Finally...a V-Blog Update It's been a long time since I've reported on the two ATS-Vs my Wife and I own. My late '16 Coupe now has 28982 miles total and 6412 miles since the engine was replaced last year. Since then the car has been trouble free. After having to replace the powertrain from the...

Sorry I took so long to reply. My bad. I've ignored this thread too long. I am not a big Mobil 1 guy. Typically, I do not use it. It's very-well marketed. Driven Racing Oil uses an mPAO base. Ironically, the mPAO base stock was developed by Exxon-Mobil about five years ago but is not used in...

At this point, I have 1290 miles on the replacement engine in my 2016 Coupe. So far, there have been no problems with the installation. In addition to the new engine, at about the same time, my dealer, Bunnin Cadillac, as part of Cadillac's Premium Maintenance program, both the engine air...

The cars you list are a pretty wide range, however, if you are really focused on the compact sedan segment, of the cars you list, the ATS-V and Guilia are characteristic of cars that size. If you are concerned about performance, keep in mind that the ATS-V is a much better choice than the Giulia...

So far, I've been unable to ascertain what the problem is with LF4 engines built in 2016 which causes only the front two cylinders to have a loss of proper ring seal which causes the oil smoke on cold start problem. There was some communication with my pal at Bunnin Cadillac, Technician Luis...
