This 1989 Buick Reatta has almost 253,000 Miles. Will CRO 505 do ANYTHING?

[@ChubbieBehemoth]

Just bought my first Reatta! Really enjoying going around learning with these videos. So thanks! 😁

You're welcome! I'm glad they're helping.

I've been looking at reviews of this product after watching Scotty Kilmer's revirew, and and gotten mixed reviews. Scotty says he's not endorsed by this product, but he DOES say Bernie, the maker of this product, is his friend. I just ordered this online yesterday, but now I'm feeling apprehensive. I'll still use it, of course, bit I'm no longer expecting much. Thanks for the honest review, bud!

Glad you found it helpful. We're still in the process of testing other products.

The oil coming out after treatment looked pretty clean to me. I expected it to be black.

[@KrazyKarlProjects]

I did too, tbh. It was darker, but it didn't look too bad.

I'm seeing mixed reviews on this. How did it end up working long term? I'm more interested in their fuel system cleaner but I'm a bit skeptical

[@KrazyKarlProjects]

Lou here, The fuel system cleaner seemed to do well. The CRO 505 oil additive did something, but it wasn't a miracle in a bottle. It won't repair damaged parts, of course. It did seem to give the engine a little more power, but as you can see from the oil drained out in the video, there's not a huge difference from when it started to the end of it.

Check Engine Light, Engine RPM Goes to Zero and back up to normal: Change the Crank Shaft Sensor

[@KrazyKarlProjects]

That's on the list. We'll be changing the spark plugs, crank shaft sensor, oxygen sensor, replacing the exhaust system, and a whole bunch of other things. Unfortunately it's in line behind the Buick Regal, F150 Clutch, and other items.

Thank you!

Buick's do suck. Scotty ran his for 15 minutes at 2000 RPMS. I would have personally ran a quart through it, before putting on a filter and topping off the oil. I've kept my vehicles on synthetic oil and now over 100,000 miles, I run high mileage oil. Mine still runs like new cars.
