Wynns Xtreme Petrol System Clean Review | H- D External Breather vs Fuel System Cleaners

Wynns Xtreme Petrol System Clean Review | H-D External Breather vs Fuel System Cleaners - Here I test and review this popular petrol gas injector and fuel system cleaner on my Harley and determine whether it has made any difference in the carbon build up on the pistons.

This content is fantastic. The endoscopic examination of the cylinder heads was the cherry on top! What field are you in? You have a scientific mind.

[egbertveer]

Thank you for this review. I'm going to try this product.

Years ago I used a product named STP. Not sure it helped. I like the idea of using the little camera to verify.

[scootjockey]

I use a " Shooter" but just in winter what i do is every 3rd or 4th fill up i put 98 octane in instead of the regular 95. Thanx interesting.

[Azzow]

Hi rev. Can't wait to see the results of the piston cleaner. And the external breather

[fijiarc]

I used a full bottle in my 17L tank...is this okay

[kieranpower]

hi i got vincent comet 500c and works very will wynns extreme, please put e10 petrol in your classic motorcycle it s old regular petrol, cheers,

[cnebs]

Thanks Alf do you run regular fuel or premium? do you add any ethanol stabilizer like "startron"?? Its supposed to remove build up from corn

[harleyguzz]

What a coincidence Alf, I have just decided to do the same experiment, only difference is that I have just made and fitted external breather systems for my air cleaner and for the sump/oil tank, Hoping that I will not be burning the oil that I have been, my pistons have quite a coating of carbon (6000 miles) so we will see after using the Wynns stuff if the carbon is disappearing or not, as you said this formula is a "petrol system cleaner " not a decarboniser, Wynns do a carbon cleaner but I cant find it on sale anywhere. Keep up the vids mate..

[Baloski]

I run an old Shovelhead and it breaths to the atmosphere, dirty I know. 
I've been thinking on the carbon issues and have decided that I too will be fitting an external breather, bit of a heath Robinson affair going on in my head at the moment. 
If you buy an after market solution and there is some out there you could well be paying big £££s. I for one will be looking forward to future episodes! Thanks Alf.

As soon as the parts come in, I will be installing an external breather, it’s a fairly easy process they have kits for sale from some suppliers and they are pretty expensive but with a little imagination, doing on your own is cheaper and you get the same results.

[otacon]

Hello mate, can you mix this with their xtreme petrol emissions reducer? Don't want to do any damage but was sold the wrong one

[paulprosser]

I use good old Red X in my Harley every other tank fill up. Have no idea if it makes any difference at all, Like the Wynns product my twin cam does seem to run a little bit smoother. But again marginal. Be interested to see the product results of a specific combustion chamber cleaner.

[briandickter]

Do you have ever have any concerns that various fuel additives that you use could damage your o2 sensors?

[paulhorvath]

GREAT Video Alf, , Definitely Following and Highly Anticipating the Outcome of Both the External Breather and Cylinder Cleaner Additive.. Interesting Point the Rear Cylinder you say Was Marginally Cleaner Possibly due to Heat..Glad I Don't have to Use Ethanol..Also I wonder if Fuel Stabilizer would in your Case make Any Difference..

[daveo]

A good portion of that carbon on your pistons will be from Harley's trick of throwing back any oil misting from the head breathers into the throttle body, been studying this and crankcase pressure issues and have bought the Feuling vented dipstick kit for my Sport Glide head breather mod coming up also.

[simonhouel]

What I don't understand is the origin of the build-up.
Some say it has to do with oil blow-buy and vented dipstick or breather catch-can are the solution.

Some say it is ethanol in the gas.

Here in France the regular gas is 98 octane ethanol free.
Would I need this product ?

[iancatlin]

Noticed you used one of my local petrol stations ;-)

[johnvaleriewelbers]

🤔 very interesting, thanks for the interesting vid. 🤓😎🏍💨💨💨💨👍🏻🇨🇦

[Dzinbhudist]

10k and your cylinders look awful… my previous honda vtwin was almost clean…
Wynns do not contain PEA which is additive which works most, try redline SL-1 or Amsoil PI these contains a lot of PEA 😉
