I saw a guy on here about a year or so back who had piston 1 blow on his '17 and he like me ran 93 exclusively and a top tier synthetic. Lost the cyl at 8k if memory serves. Saw another post around the same time a woman lost her #1 piston at only 3k miles she though was on 87 and DEXROS dealer oil.

I tried to find that post as I commented on it, but none of my old posts/comments are showing up. Not sure if things were deleted when the site was updated?





Yea I honestly plan to get rid of my Cruze soon as I'm done paying it off (8 payments left!) I mean its an OK car. No real issues other than my wonky transmission. But with the piston issues and the fact car is now discontinued so it's going to be progressively harder to find parts as well as more and more expensive to repair, time to move on. Its also not that fun to drive. Great MPG though (I average 34 in city and 43 on the highway, hand calculated).

There are other benefits to running 93 top tier gas other than just the octane increase. On top of that Cruzes have such a small tank, you're only paying a few bucks more per fill-up. Granted that adds up over time, but still. Pick a chain and stick with them. Most of the big guys have a rewards program so you can get 93 quite cheaper. I know with Shell I get 10 cents off the gallon with my Shell card.
I have no problems getting parts for my 1995 Ford Escort or 1999 Oldsmobile.

No kidding. There are already Cruze engines in and/or headed to salvage yards due to wrecks and other issues. If you need a piston and couldn't buy one new, single or sets of pistons can be had from a salvage yard.

Pistons are approximately $30, one cylinder's worth of rings is approximately $30, a connecting rod closer to $40 (internet pricing). At this point, parts not only are readily available, they're pretty cheap. But the supply of wrecks far exceeds the supply of out of warranty blown engines, so the junkyard engines are cheap enough to make it hard to justify rebuilding with new parts.

I threw the junkyard engines out there as an example. If it were me, there is basically zero reason to use anything other than new parts because there are "old" pistons and "new" pistons, and if I had an affected engine I would want the newer updated pistons to avoid future problems.

I've seen complete (turbo, manifold, injectors, hp pump, manifold) for as low as $650
Yep. At that point it becomes a balance of how much labor would cost to rebuild the engine with new pistons (you'd want to replace all 4 with the new, updated design as a preventative measure) vs. how much it would cost to install a used engine. If the used engine comes with the new, updated piston design you can factor that in as a benefit.

2018 engines don't cost much more than 2016-2017.
I can't find a complete 2019 engine for under $1k though.
If a 5000 mile 2018 is cheaper than a 25,000 mile 2019, I'll take the 2018 every time.
AFAIK there's no difference between 2018 and 2019.
