Product worked just as I'd hoped! Truck is running smoother and fuel economy is back up to what it was before. Great service and delivery was super fast (next day).
Bought the inject. cleaner to see if it would help with some balance concerns I was starting to see. It did seem to settle a couple down to a comfortable rate. So far it's only been 320L of fuel used but have noticed it's smoothed out the engine and definitely sounds better. No fuel mileage gains but I wasn't expecting that to change much if at all. Another 180L to burn and I will be switching to the Performance All Season. Can't speak for service as I picked up in store.
Great service, fast shipping and great products
Use it every 3 months with Stanadyne Performance Formula the rest of the time and they are by far the best products for the 6.5 TD in my H1.
Great product. I have been using it for years.
