Hi All,

My 14 cruze diesel is not well. I had the car since new currently at 50K miles.

So here is the run down all happened over the weekend as I went on a 100 mile road trip. Car had no issues prior, but for the past 3 years I was drivng in the city I figured a fuel injector cleaner could not hurt. I was wrong.

49370 new tank of diesel (from a random BP station) + 20 Oz of Techron® Diesel. road trip. highway speeds, varying elevation.
49400 change fuel filter message came on. Fuel filter was changed last summer @ 42093. Some time after this I notice that car became sluggish, on highway. Because I noticed this on my way back I tried to go a little faster. Going on an uphill I floored it it would not go past 60 mpg and higher than 4K rpm. after a minute of driving like this the following happened:
49457 CE came on. reduce powers message. message to shut down the engine. The car basically coasted me to 0 and the engine turned off by itself. after a mineute I was able to restart and get home the rest of the way (may be 50 miles)
Once I got home I conected obd II scanner to reveal code is P2428 exaust gas temp too high. bank one. See freez frame data below. After about an hour of car sitting I went for a drive where I was not able to repeat the issue. I drove the car in 2nd gear at 4K rpm (40-45 ish mph) for 5 minutes the temperatures did not go anywhere near 800C at Idle I get 185C. neutral 2K rpm egt 195 C.

Please help me troubleshoot and resolve this issue.

Did you pour the whole bottle in?

I would go out and buy another 5 or 6 gallons of diesel and put in the tank to dilute down the cleaner. I assume it will clear out as more diesel is added to reduce the mixture. The CEL should clear after a few drive cycles if the temperatures come back into range.

Just a tip, over the past 100k miles I've ran a premium diesel that has an additive package (injector cleaner, improved lubricity, improved cold weather starting) and have had great luck.

I'd follow the advice from the post above and avoid using anything like this in the future. From what I recall, GM doesn't recommend using any additives as they simply aren't required. Unless you're running some bootleg Diesel fuel, most fuels you're going to buy at a station have everything the Cruze Diesel will need.
