Sea Foam SS14 Engine Cleaner and Lube Foam

Certainly did everything I hoped it would do, wished I'd kept my eye on the elbow piece to help with keeping the hose around the throttle body hose, it snapped while installation and I only got to use about two thirds of the product. It did however do what it is supposed to do, it cleared out so much build up in my recently purchased 16 year old land rover V8. The amount of smoke and foul smelling gasses that flowed out of the exhaust pipe was alarming. I had to find an unused corner of a factory car park to do the job as per instructions. The run on the local bypass caused alarm for many of the other drivers I'm sure, and for a few days afterwards it would smoke even after getting up to temperature. And the smell is quite awful so try not to have your heater blowers on when at a junction waiting in traffic. The immediate effects were a noticeable acceleration performance, the faster start on ignition, the noticeable holding of temperature without any peaks and troughs between idle and high load. I inspected the spark plugs before and after the treatment and the condition of the cylinder chambers were noticeably shinning more than before and by changing the sparks for new, the noticeable misfire it had before has gone. All in all, it has reduced the fumes, increased the performance of the spark and a believe, been part of a thorough service that has increased the efficiency of this old engine. I'm seeing an increase in fuel economy, a smoother ride, a lot less of a visible wobble at idle and after a combination of other essential jobs (oil, filters, MAF, sparks, belt, coolant and new exhaust / O2 sensors) it's feeling like a new car. I'd suggest using SeaFoam on an old engine that has limited or very poor history, but do it away from your neighbours. The results are awfully antisocial.

Great stuff this to decoke cyclinder heads and pistons, used on my Harley and definitely worked reducing soot from my engine and exhausts. Not tried on anything else but will do for CO emissions sensors.

Great product. Will definitely use it again. However, I would like to warn those doing it the first time at home. As you will see in the video clip I made there will be a lot of smoke depending on how gunked up one's engine is and the engine light will most likely come up. Engine will vibrate - misfiring occasionally etc. Nothing to worry about. Once the process is over engine light can be reset by using one of those obd2 port dongles (i bought one off amazon for £8). You can also see fault codes at the end of the clip I personally had. Yours may be different though. Now, engine runs smoother and it is recommended by seafoam to use it every time you service your car. I am not a professional mechanic just an ordinary diy person who experimented, got stressed out about this experience so that you don't have to. This product was used on a Mazda5 2l petrol engine MZR aka Ford Duratec. Hope it helps someone

Does exactly what it says on the tin I use this most of the time when needed first deliver it next day straight away

I'd heard good reviews for this and fair to say it's pretty good but not a cure all miracle. Engine cleaner,yes,lube foam no. It is good but i expected a bit more than a WD-40 alike

I have a Honda Jazz 1.5 with direct injection, it has not been clean up since brand new. My car got better respon and smoother at lower RPM range... Will consider this product for next service.

No offence to the seller they did amazing and I got my item swiftly from Amazon per the norm but it's overpriced for what it is and what it does! I found a better brand and you can just shot it in your petrol tank and drive with it and it'll clean the top engine, much better than this faff about with the nozzle and running the engine to use it! Ridiculous!

I know this stuff is great but my bottle had a busted tip and half of the can just went on the ground and i couldent stop it , quite upset about that
