Topic: Fuel additives

[beemerbum]

Just cruising through some posts from 2013 regarding NGK D8 plugs versus Denso X24ES-U. In a few posts from Hondaman, he talks about modern (alcohol) fuel lacking ability to "lubricate" the top end and keep the piston tops clean. Leads one to wonder if there are any fuel additives out there that are of benefit whatsoever in our SOHC motors if non-alcohol fuel is not available.

 I read recently where he puts a little dash of 2 stroke oil in his gas. I personally have not ever done this.

Shell V-Power E5 fuel we have here feels like it has other (good?) additives in it. My fingers feels like it has lube stuff in it.

Valve guides needs a good oil too, not too thin and changed before it has worn out the good additives making it even thinner as I have concluded when reading various forums, a Porsche forum included.
Porsche had air cooled engines, that's why I had it in my searches.

I use a fuel stabiliser and octane booster. It’s supposed to stop the fuel from turning to s***e in the carbs and fuel tank.

Me too.

The irony is, that fuel stabilisers usually contain... alcool. But that doesn't mean, they can't be useful.
About Shell's V-power which also I prefer: although the pistolgrip at the gazstation says 5% ethanol, it actually contains none and neither does BP's Ultimate. European law demands pistol grips should indicate either 10 or 5%. That's how it is now, in the future... who knows.

 I'm a fan of seafoam. It cleans carbs, I've used it several times on a lawn tractor, always works. It removes carbon as much as it can, seems to have reduced carbon caused piston slap in my 8.1 GM engine.
  I use an oz of  amzoil 2 stroke oil in my old bikes to protect the tanks and exhausts.
 
 I used to think it's all snake oil but have seen results when a problem goes away with no other changes.

ultimate best fuel additive for these?...more fuel, and lots of it, all that you can use.  Ride the damn thing.   All the time.  Go for a ride.  Go.  Turn off the internet.  Go now.  Use that crappy old gas up and get some more.  Shift at redline every time. Go

We’re lucky enough to still have “super” gas with no ethanol. BUT, i’ve Noticed when pumping from pumps with grade selection choices, that the first few litres are whatever the last guy pumped. A bit obsessive, but Inow take my 5 gallon jugs and fill them after dumping a few gallons in my old JEEP.

Carbs no no longer have that greenish tinge in the bottom of the bowl.....  Shell also has a few stations with dedicated pumps for their V-Power and I have most of them mapped in my area....
