Seafoam

Unfortunately, I'm not being sponsored by Seafoam.....

 

But, this stuff makes all your usual additives such as STP & WINN'S etc look like gnats pee. 

 

Having had trouble with blocked idle jets, and not having time or knowledge to strip the carb's Seafoam was recommended. 

 

It's expensive, very expensive, but I bought 2 cans anyway. 

It says on the instructions that the stronger solution is, the better. 

I put the whole can in with half a tank (about 8L) and took the bike out. I did lots of low speed to try and encourage it through the idle jets. Then parked up for a couple of days before talking it out again, hoping the solution sitting in the carb's would loosen up and dissolve any crud. 

 

Well, strewth!

I've not had many hours on my bike, but flippin' 'eck, once past 5k, it's now scary, really scary.

Had my bike run the way it does now, when I first bought it, I'd have been through the first hedge.

Whatever cleaning it's done, it's made a massive difference to performance. 

Blocked idle jets are worse though, which is obvious if you put something in to clean, that dirt's got to go somewhere. Booked in for a professional clean

 

Get this though....

I put a bottle in my 14 year old car with 1/4 tank of petrol, and gave it a right good thrashing for 20 minutes. I now have a very noticeable difference in performance (only rev's to 6k, so not as good as the bike), but more amazingly, my fuel consumption has gone from 19-23Mpg to 31-34 Mpg around my local roads, hoping to get way more on a motorway run. 

 

@Fender1515 it works in diesel too.

In oil you will add every time you have a oil change.

For fuel I use it every 2 or 3 full tanks.

Usually I will add some if I fill up before coming home and the bike will stay without use for a few weeks.

The can will have instructions how to use and how much.

All in US imperial units

Yes, what @husoi said 

 

I got mine on eBay, this was the cheapest I could find on tinternet

ok for fuel but for oil i wouldnt.

oil has (even the cheap grades) have lot of good additive's and properties already in if your concerned anout the oil just change it now but use the next grade up from what is in. so you could just to get a slightly more premium oil say with ester content.

[RideWithStyles]

Cheaper to just get a better spec oil from a trusted manufacturer than add random stuff from a bottle, question to ask yourself is what is in the sea foam? How much of each element or chemical and why? Then see what’s in your oil and how much and why?
So does adding something what is in the sea foam to the oil neutralise an additive or package that is beneficial in the oil that you already paid for? Or does it add more of something that is already in but is already has alot in but you’ve just doubled it- then does it need double? Then does that have an after effect of what is already in it? Does it have the possibility of increase wear, heat or foaming or lack of protection to metal parts? 
 

all ill say is just make sure you know what your adding and why, then if your happy with the positive or more importantly the very potential negative results could be.

I couldn't disagree more with you.

 

I use high end Castrol oil on the bikes and seafoam keeps the engine clean.

Had an issue with the clutch slipping on the shadow and it was solved with seafoam rather than buy a new clutch.

You can't compare what seafoam contains to the normal engine oil additives.

Is the same as comparing carwash shampoo to ACF50

From what you've both said, it seems like it's just what is your personal preference or experience, having spoke to David Silver recently at his Leiston shop, they recommended 10W/40 4 stroke semi synthetic oil from Motorex 4T,a Swiss company that adds no moly additives, which is what they stock for my 40 year old superdream, so would adding some seafoam to this oil be harmful or beneficial,  I must admit I am a bit confused , but will look at all its contents first before deciding, thanks for showing me both sides, just concerned as it is an old engine

I can only speak based on my personal experience with a 38yr old bike that I bought in a sorry condition.

I first used it following advice on shadow forum and pretty much everybody there uses it with great results.

I use it mixed with Castrol Power 1 (full of additives) and the bike runs smoothly without any issues.

I would say that using a "clean" oil (no additives) and add seafoam would be the best way to keep the engine clean.

I think we all agree, added to fuel is a way to keep the carbs clean

You're most welcome.

Glad to help

Some scientist evidence.

@RideWithStyles

Thanks for posting the video, it does seem logical that a product capable of stripping gunk/dirt from within a fuel system, would also have the same affect on oil.

The correct oil, which should be flushed properly when changed is all that is needed.

 

However, I stand by my review, I have two real world very noticeable results from using Seafoam in my fuel. In fact, as part of my ongoing carburettor issue, I rinsed my fuel tank last night, and it was absolutely spotless, which is surprising considering it's 19 years old. 

I shall continue to add Seafoam to fuel, it works.

I don't mind using redex and similar for diesel injectors, in the fuel. 

I used to use something called slick 50 in the oil, it reckoned it coated the surfaces with a teflon coating, made it all more slippy so less grindy, worked in my mind and l was happy with that.

Nowadays I'm happy with regular oil changes and wouldn't use any additives.
