About this deal

I had asked the dealer to investigate at the previous service two weeks earlier (Even though I suspected what the cause may be) but you can guess their response - nah mate there's no problem. With the 10% ethanol gasoline that we are forced to use here in the states, useing a fuel additive like that is a good thing every 3 or 4 tankfuls. I have some Marvel Mystery Oil that I used from time to time in the Diesel tank of a pressure washer water heater.

I too remember the smell of burnt Castrol R, but that was back in the day when bikes were used every day, engines were regularly de-coked and ordinary oil was still found in pools oozing from the ground. Fatty acids are polarised molecules comprising an oily, hydrophobic (water-hating) head and a hydrophilic (water-loving) tail; the hydrophilic ends of castor oil molecules are adsorbed to the metal surface, leaving the oily heads protruding.

Does anybody know where i can get some original castrol R racing oil from, i know that you can get an oil that smells similar but i don't want it just for the smell, back in the late 60's early 70's when i first started helping Greg Lawton and Dave Brierly with their 50cc race bikes, they swore by rebuilding their bikes using castrol R on everything and had very few problems with mechanical issues so i would like use it on my rebuilds.

The best for a roadgoing bike in modern times is the modern fully synthetic 2 stroke oils run through the oil pump. Castrol POWER1 have been developed with cutting-edge formulation technology, underpinned by more than 100 years' experience in motorcycle lubrication. You're also looking at oils with good flow charateristics, so if its a new engine, i'd be looking at full synths on a race engine.But they were far from perfect In particular they lacked what, at the time, was termed “oiliness”, the ability to adhere to metal surfaces in a thin, continuous film.
