I have used this on my porsche cayenne gts. 4.8 v8. Most Porsche owner would even know what an engine looks like.I have two catch can installed and this stuff works in my view better then moly lube stuff.Only issues - if take off the pcv value make sure u have a fan blowing the gas away from you ... but works like a dream. Car is running smoother, accelerating is better .. fuel cant tell at this stage

Small can but goes a long way. Fantastic results, car pings less on acceleration, idles and drives smoother. If you dont use this as on regular alignment with an oil change service or every second one I would highly recommend doing so. I've driven 120k k/m without using it and wish I knew earlier.

I used half the can to clean the piston crown. Probably too much which took me about 20 cranks to start the engine (is that hydrolock and is it bad?). Only some steam when start up first time, after I drive the car (3mins) to highway to give it some rev there is no smoke visible from my mirrors. Car definitely has more power now (even though it feels no different but it can crawl over the garage step without any throttle, no more light pinging at low rpm when hot and the vvti rattle on cold is gone (strange). Do I have to change oil afterward?

I don't usually write reviews, but this product is defiantly worth writing for.I've been using this for the last few years for my annual service, and it has really improved my fuel economy by around 15%.I had to physically carbon clean my intake about 4 years ago. and by using this product since then, it has kept it free of carbon deposits (i recently pulled the intake apart to check).Highly recommended esp for older car or engines suseptable to carbon build up.
The engine got more responsive after this treatment. Removing spark plugs and spraying directly to piston crowns could be challenging for diy people, but it's very beneficial to free up the carbon for better compression.
I've used the entire bottle on my 2002 Toyota Corolla (1ZZ-FE / around 185,000km) which has been suffering from crazy pinging (tick tick tick) noise under acceleration. It almost sounded like my engine was going to blow up anytime soon. I used the entire bottle and followed the instructions, then the pinging noise disappeared COMPLETELY. I could instantly notice how smooth and responsive the acceleration has become after using this product. HIGHLY recommend this product to anyone that owns old vehicles.
Cleans out all intake parts and inside the cylinder. Many ways of using and cleaning everything without disassembling parts of the engine.
I use a cleaner every 6 months to keep the intake valves clean. This helps with the smooth running of the engine and gives me peace of mind. I am happy with this product and its ease of use. One suggestion I would have for the product is can Nulon calculated the TIME it takes to empty half the can so we can use the product as instructed. Otherwise a great product.
I'm a mechanic by trade. This product while does the job in a bind is nowhere near as good as some of the competitors that are available at other retailers especially for the price
Had a Datsun A12 donk which had an insect infestation in No4 cylinder, occurred whilst in extended storage. Little buggers got in via the exhaust and open No.4 exh. valve. Piston was frozen due to corrosive effect of excreta on bore plus residual bodies built up over time. Got some Nulon and sprayed in plug hole left for a while and got a fluid extraction device which sucked out the dissolved gunk. Had the head off and with a bit of CRC stuff plus a gentle tap with a block of wood freed up the piston.
