Fuel additive

Petrol companys would not recommend additve ...why ? Because is considered a enviroment No No. Yet i have a box of Gulf lead replacement?
Must admit marketing is big business ..i would like Jim to run a fuel treated dyno against a None Treated just to see the differance...he my be surprised at the outcome :shock: As the bores are lubed and sealed better with UCL the dyno may show the added fuel as better BHP?
 
Many thanks for all the replies and information everyone, i'm amazed that this post created so much interest,
regards,
Dave.

You nailed it. I suspect it is also how the oil is present, as thoroughly mixed in the fuel versus poor dispersion through say a valve guide.

My understanding is that lead replacement products don't actually contain lead. They contain one of three products: phosphorous, manganese, sodium or potassium. I don't believe that lead replacement, or lead additive products, actually contain lead. However, I am not sure and would welcome clarification from those who may actually know.

There is one 'lead' additive available in the UK: http://tetraboost.com/info/
 
"Dry" fuels like methanol or nitromethane can use a bit of light oil mixed in that helps preserve pumps and such plus fragrances often added to lower the nose and eyes annoyance, which is one way to get it about right in our engines, just enough to detect by your nose but can't see any smoke. Propane is another 'dry' engine fuel but don't seem to need oil added yet engines famous for lasting a long time and with hi octane can be used to great power plants. Propane and methane can carry pollutants in them that do harm surfaces though.

Acetone is a common gasoline additive that users say about 8 oz per 10 gallon significantly increases mileage. My '96' Olds 3.1L V6 Cutlass gets about 27+ mpg @ 70+ mph freeways so will see what acetone does on 1500 mile salt flats trip this week pulling a small trailer with mini bike and SV650 and stuff.

We are NOT talkin To much oil..stick to the facts..the guy enquired about upper cylinder lube [fuel additive] and not adding large amounts of engine oil to the tank...
When lead was removed from fuel this increased wear,as did removing sulfur from diesel..Bosch produced a paper stating the onward crusade to protect the planet ,was costing in engine advanced wear ..fuel injection equipment was failing due to lack of lube ..my local fuel injection repairers advised strongly against the use of "City or Low sulfur" infact those fuel station terms have long gone?
i personaly aint bothered if i am 2 hp down..just happy that the motor is getting vital protection ...forget about the lower ron rating ..whats it matter ...just add it ..i have not noticed a huge fall off in power ..and after 45 years i aint worring now :shock:

No doubt small quantities of oil are not going to cause any damage or cause any big change in dyno readings short of lowering the octane enough to cause detonation. My bike runs 10-1 compression and it would not take much oil to lower the octane enough to cause damage.
No big concern on a 8 to 1 motor.

If you want to add lead for valve seat protection then buy a can of leaded race fuel and add it it at 10-1 ratio. You will get more protection than you will get out of any legal fuel lead additive.

Oil in the fuel does not help protect the valve seats in any way. Jim
 
Wow Lab, that Tetraboost sounds like magic...octane improvement and engine long livity! better get stocked up... head Rebuilds...what's that? :lol:
plus "experts" have agreed this stuff really works....wonder who the experts where?...proberly a couple of guys down the Boozer? Listen to them..." Ive you'sed Trtra boost for years ,,with no probs" His mate replie's Jim "you never use your Norton"! Jim replies " since the missus got gout,she carnt start it" :D

Lead ain't really good for engines or environment though was half fast necessary evil with extra mean lead oxide eating additives thrown in to keep it from building up and not coating tail pipes greyish - until metallurgy and manufacture got up to speed. I'm sick of Plumbum in my life, my patients, old engines and streams and sewer systems polluting oceans. Scan these for how much a bad boy to feel kicking up heels like we did in the 50's 60's 70's on hi test tetraethyl lead with hyper active attention deficient dyslexic brain abandon.
I got my biggest doses in ditches, basements and wall spaces pouring molten lead [sometimes in the rain] in cast iron sewer pipe splattering-exploding flashing off water pockets then chisel pounding it down work hardened compressed so didn't have to do it again a long time. Overhead pours in runs of pipe under cement catwalks were horrific.

hobot you have got me phucked...... how is it that you can spell out all this in such a concise manner and when i go to the link attached i am hoping for enlightenment..... then i still dont understand what you are talking about... Lateral thinking has hobbled me from time to time.. Just sharing and do really enjoy and value most of your posts..
 
Well basically lead compounds are bad for engines and bad for the world to use just trying to avoid detonation as that's about all its good for in our engines and lead added from bottles does not increase octane protection enough to hardly tell before its leaning out power burn. Octane is a hydrocarbon that burns but lead compounds and it required dispersant agents don't. On the other hand its too late to save me and likely past point of no return from major extinction event too so can't argue much sense against living it up fun as ya can before the end.
 
Whats in the octane boosters

http://www.brighthubengineering.com/mac ... -boosters/

Much of the performance care/DIY octane boost discussion on the web zeros in on toluene as a readily available, not too expensive gasoline octane booster. The following recipe is floating around several places on the internet (for example: http://www.clubwrx.net/forums/engine-mo ... mulas.html as a homemade octane booster:

100 oz of toluene for octane boost
25 oz of mineral spirits (cleaning agent)
3 oz of transmission fluid (lubricating agent)

Discussion following the above recipe at the same web site points out that the latter two components in the recipe aren't really needed in modern engines, and that simply using straight toluene as an octane booster additive works fine.
