When the active fuel management is running the cyl it shuts off but it still has to be lubricated so it sucks oilinto the cylinders and when it goes off and it will burn the oil in the cylinders and you will have a blue puff of smoke and will eventually foul the plugs in those cylinders. **Q: Will this work on a 2018 - 2019 chevrolet suburban lt with 6 speed transmission** A: It works fine on my 2018 Silverado with 6 speed Transmission ## Customer Reviews ### ⭐⭐⭐⭐⭐ Workis like charm *by M***A on 24 June 2024* Very good and keeps my V6 Camaro in V6 all the time, it saved my torque converter from failure and also improved in town gas mileage a lot. ### ⭐⭐⭐⭐⭐ Review *by N***E on 22 August 2025* Fonctionne parfaitement.
