I just bought this to see if it made any difference to my 70k km diesel injectors of my Ford Kuga TDCi. I have never used such a product before so it was more of a preventative maintenance.Can't really say I physically experienced anything magical with it as I was not treating any symptoms. After putting this product through over 2 full tanks, there was no difference in the way the engine sounded, no real difference in the way the car drove and no big difference in fuel economy, just very slightly more economical but not justifiable with a $18 additive.Perhaps just something nice to do once in a while as it wont hurt it.

Not cheap but happy to pay a little more for a quality product. Still running on initial tank of diesel and all seems OK. This appears to be the "Good Gear" so please consider as its well worth a try.

I put this product in my diesel Ford Territory, as it was starting to get a slightly rough idle, and was surging a bit on the highway. After a few hundred km, both problems disappeared. I use Penrite in all our cars, 4WDs, boats, small engines and chainsaws, have been doing so for about 30 years. It has always proven to be an excellent product line. I have tried other brands over the years, but Penrite always proves to perform and outlast the competition.

Having a Toyota Landcruiser, I like keeping the injectors working efficiently. I usually use the Toyota brand but could not find the product anywhere near my present location. I thought I'd try the Penrite product. I was highly satisfied. Follow the instructions for the best results.
On the basis of Penrite's high quality oils, I used this injector cleaner as preventative maintenance. There were no adverse symptoms beforehand, and the elderly diesel engine continues to run well with no smoke -other than the usual puff at cold start-up. I'll continue to use it now and then to keep the fuel system happy.
Noticed black soot around the exhaust of our Santa Fe diesel, along with a little shudder, and hesitation when accelerating.Thought I'd give the Diesel Injector Cleaner a go, adding half a bottle to a full tank, and was really surprised how quickly it worked.After a country run, no black soot around the back of the car, and engine running smoothly.I'll give it another go at the first sign of rough running / soot.
Better then KY. Your injector will love it! No more riding like a bucking bull but a sleek mustang on acceleration. Good stuff!?
A product that really does exactly what is says. Simple to use by adding the amount as indicated to your fuel when you fill up your vehicle. Bottle neck shaped to fit for easy pouring into your fuel tank.
This isn't the cheapest diesel injector cleaner, but I've tried others and found this one to be the best for my two vehicles. It starts to work straight away and within a few days, they are running more smoothly.
Honestly don’t know why I bother buying these as they do nothing. It’s not like it reduced my fuel economy or made the car perform better. Maybe for older cars, they might find the value in these.
