Seafoam is a great product that works!
I've watched many independant reviews... for Seafoam and various other products you can use in your combustion engines from fuel additives to oil additives for small engines and big engines and Seafoam is a product that works, i won't go into the details as you can see the infromation for yourself all over the internet. I have a 23 year old peugeot 205 that has been owned exclusively by older women and i'm the first male owner, so it's a safe guess that the car has never been stripped and cleaned or treated with anything other that the bare necessities to make it run. You can use this product in both the fuel and the oil but I wanted to use it exclusively for the fuel as I used it in combination with Seafoams other product which is a cleaner/lube for the cylinder head and air intake system, after applying it to the fuel tank and spending a good 5 minutes rocking the car to mix up the 16oz of seafoam with 40~ liters of fuel i ran the engine and within a few minutes the exhaust was billowing out thick whites clouds of smoke. As the engine ran I was applying the cleaner/lube via the air intake system right at the throttle plate as instructed and I ran the engine at an increased rpm as instructed to make sure the product was being applied correctly, the engine noise profile changed dramatically over the course of the 7~ minutes it took to apply the entire can of cleaner/lube meanwhile the engine continuously billowed out thick white clouds of smoke. Engine performance has improved, the engine sounds different and the throttle input feels a lot more sensitive compared to how it previously was which felt sluggish and not very responsive which you don't want in any engine. As a follow up from my application and test drive the engine ran better, the throttle input feels like it would on a motorbike or a much newer car and I'm very happy with the results, when i stripped the cylinder head off the engine block the pistons and valves looked much cleaner than i expected as there was a lot of carbon buildup and some of it had crystalised from years of use with no cleaning treatment being performed. This is my own review which is un-biased as i'm not paid by Seafoam or any other company, I can tell you as a real person that it really does work, it's expensive which can put you off of some of these types of products as there are so many of them out there and you might not know which to get but after my conducting my own research i came to the conclusion that Seafoam worked and it works well. The end results I can't be happier about as my 205 feels brand new and everytime I use it it just feels incredible like a brand new block was installed.

DID NOTHING FOR MY VW CADDY VAN
Bit of a rough idle and occasional 2 or 3 st...arting attempts to get a high mileage VW Caddy 2.0 Diesel van going, so thought I'd try chucking in a full container of Sea Foam in a half full fuel tank (about 8 gallons), to see if it made any difference. Alas, it didn't. But it didn't do any harm either. Next time though, will try using 100% Sea Foam to prime a new fuel filter when next due a major service, to see if it makes any positive difference.

Easy to use and results speak for themselves.
I did not feel that reassured ...this product would clean my outboard rough idling condition but it was worth a try. After some initial problems, when it stalled, I left it for a day then on returning it ran smoothly. I hope it continues.

Audi TFSI engine
Always sceptical of a product like this, but hey don't knoc...k it till you've tried it , so I tried it, TFSI engines are known for carbon build up on the inlet valves so with 70k under its belt it's needed, I followed the instructions as stated, and to be fair it did make a difference the car picks up better more response and free breathing now, don't advise doing this in a small street though as the sea foam burning off really does produce some crazy smoke! Scary but is normal had a thick plume of black smoke released and all was well! So yep gets a thumbs up!

Wouldn’t be without it
Used for years when in the US in a variety of our car...s and trucks. Glad to see a reputable company selling genuine bottles. Buy it often, use it regularly. Most times I tend to use every other oil change but also use as a fuel conditioner when weather is cold or vehicle standing for sometime. Never had any issues.
