To whom it may concern
My Nissan Regulus 3.2 diesel started showing an engine warning light. Paul’s Auto Workshop idenfied it as an Injector Bypass problem, costing $4-5k to fix.
I spoke with Phil at Fuel360 and then tried some of their diesel treatment tabs. After 2 tanks of fuel the light went off. I have done 8000k since, using the tabs, and the engine warning light hasn’t come back, plus the car is running stronger than ever.
Seriously, give it a go.
