Fuel/ octane

[BigKel]

I have run 95 in my bikes and petrol vehicles for ages (a bit each way I suppose) but I do add Nulon or Flashlube lead replacement fluid, as I have pulled down a few motors run on the fluid and they are always nice and clean almost as clean as LPG powered ones, someone will probably tell me I am wrong but I do what I do.
just a thought I wonder given the advances in small turbo diesels if Triumph have considered the Manufacture of a Turbo Diesel Rocket 3 the odd cylinder configuration lends itself nicely to Diesel application , and the torque
figures are amazing a 2.5 litre Navara can tow over 3 tonnes, this used to be Landcruiser and Patrol only ratings.

Diesel, wash your mouth out with soap Ken.

I don't think I am the only one who has filled up their vehicle with what we thought was a high octane petrol only to have the engine 'pinging" with pre ignition on any load and then running on when you stop and turn off the ignition, an obvious indication of low octane fuel in a high compression engine, the 460 (7.3litre) engine in my F100 runs a 10.5 to 1 compression and was built to run on LPG (100octane) if I have to run it on petrol I require 98 octane to prevent the problems ,so I have had a few occasions to doubt the validity of the quoted octane levels at the servos.

Ethanol is basically pointless, or worse than pointless. It's hygroscopic so it attracts water to the fuel, and it's not even more ecologically sound. Sure, the vehicle outputs a dash less, which is compensated for by making and transporting those oceans of ethanol. I want a low octane fuel without ethanol already...

if it attracts water is't that a good point it would soak up any water that might of got in your tank

Don't take this the wrong way, but does anything in this world make you happy?

Sure. Not ethanol, though.

if it attracts water is't that a good point it would soak up any water that might of got in your tank

It's more like it soaks moisture out of the air and adds that to your fuel.

Ethanol does suck that's all we can get here in New Jersey, been that way for many years. (I treat all my fuel with Starbrite Star Tron, )it's really bad for boats, old cars, old motorcycles that vent to the atmosphere, if u have fuel injection hygroscopic fuel is usually not a problem. I also use Chevron Techron every 6 month to clean up all my fuel systems it works great. 87 octane fuel is junk I won't put in my lawn mower you should use at least 89 octane it's a better grade of fuel. IMO

I know ,I know, but electric bikes are starting to creep into the scene so I foresee a turbo diesel bike of some make appearing sooner or later it makes sense, one of our relatives has a new Peugeot 2.2 litre Diesel SUV ,7.0litres per 100k (about the same consumption as my Touring),can legally tow 2.000kg seats 5 ,so imagine a 2.3 litre Turbo Diesel in a rocket Touring frame ,with the correct gearing and 350Nm of torque at 1500 revs it would be something to think about ,and run on the smell of dare I say the smell of an oily rag.

Always run 98 in the bike and car, will run 95 if thats all I can get, but that has only happened a couple of times

Hi folks. here is a couple of interesting pics. The piston which is dirty is from an injected bike which has done approx 7500kms on our 91 oct regular fuel. The clean piston is from a carburetted bike(should run dirtier right?) with 38000kms on the clock and has been run on our 98. This is one reason why I recommend folk to use the 98 in their bikes even though the manual says you can use reg fuel...

Carbon build up has nothing to do with fuel octane. It has everything to do with fuel/air combustion efficiency and how well your engine is tuned. The difference is most likely attributed to cleaner/detergents in the fuel. Some brands have better/more cleaners which will prevent carbon build up. Others have less and will be "dirty".

I read that all auto fuels in the US have detergents added from the refinery (required by EPA). The difference is name brand fuels- Shell, Chevron, Texaco, etc. take the fuel from the refinery and add additional cleaners to the fuel. So all fuels in the US come from the same refineries regardless of name brand, and the difference between name brand fuels and cheap branded fuels is the additional additives. Boy, I think I just confused myself!

All most all the fuel sold at gas stations in the US have 10% alcohol regardless of the octane rating. I have one secret station I frequent for pure gasoline.
