Works wonders on a cb500/4 with intermittent carb overflow issues. They do various formulations, redex lead replacement, injector cleaner, carb cleaner and fuel system cleaner then theres redex diesel. My dad used to take mpg very seriously with his BMW r80rt, he reaconed that there was just about enough extra mpg from using it to justify the cost setting aside the fact BMW were about 20 years late fitting valve seats that could cope without lead. I just took this on board and ran my BMW's with redex regardless of if valve seats were hardened type, the Honda however just got redex if the carbs dribbled. Price varies a lot. Definitely has benefits both on diesel and petrols - toughest test is use it in a hand cranked diesel - the transformation there is amazing.
I have been using Marvels Mystery oil which is supposed to have some secret mystery ingredient LOLAnyone else come across this stuff?Very popular in the US and I originally bought a bottle to try and free my seized engine (which it didn’t) and just using up what is left
These things are just amusing, all the different brands, that claim so much. It's OK if the content of the tin gives you something convenient to use, but they ain't in any way magic.Most are just using Naphtha as a solvent to get the stuff into place, some are just mineral oil which remains when solvent evaporates. As I understand it, nothing dissolves carbon, but any gumming, varnishing etc that can be holding it in place in some circumstances may become dissolved by the solvent in use. The other components may physically flush it out under mechanical dynamics (thrashing it) if it can be released. Edit :- with link to safety data sheets that shows 60% plus is one component, solvent. http://www.marvelmysteryoil.com/sds/Make a nice corporate logo that looks like "ye olde oil company" 25 pence of solvent content plus the rest of 15 quid in marketing and puff, keeer-ching goes the business The big named one beginning with WD looks like just the same from its data sheet, mineral oil left on surface after solvent evaporates. OK if you want it but nothing special.
