A squirt of Techron (USA) or Redex (UK) in the fuel tank just before every oil change will help keep your fuel injectors unclogged.(upper cylinder lubricant) OK for keeping valve guides lubricated, also in a strange way helps reduces your engine "coking up"/carbon buildup on cylinder head & piston crowns(in the long run)
Quite often. "Noisy" valves are caused by a growth (bulge) of carbon on the valve stems which is only cleaned/ removed should a overhaul of the cylinder head be required about every 25000 miles ? but often overlooked until something breaks, putting this stuff every couple of fill ups will break up the soot sticking on the valve stems and exhaust ports,only visible sign is you may? have some black/grey smoke out of your muffler, if you "floor" the accelerator hard (but not much) clears after about a drive
Quite cheap to buy about $2-$3
Ps: don"t be tempted to put the complete contents of the tin (only a tiny tin) in your tank (a mate of mine did this) You'll end up "smoking" the neigborhood out!!
(good for a laugh though
) I used to do a similar stunt with the oil pump on a 2 stoke motorbike, open the throttle wide and pull the control cable to the pump wide,thus creating a huge white cloud (I'd be somewhere inside it, Could only hear the bikes engine revving
If you weren't used to seeing a 2 stoke at full throttle ,people would panic , perhaps phone the police,happened to friends
