castrol a747 vs shell m

[jock]

has any one tried castrol a747 and how does it compare to shell m?

[tom]

I have tried both oils in KT motors, they are fairly similar, both being castor/synthetic blends. I didn't really notice any performance or longevity differences in the motors, the only thing was the A747 left more deposits in the combustion chamber and the exhaust. I suspect it has a higher percentage of castor in the blend.

Long ago i switched to ELF HTX909 and it would take a lot of convincing to get me to use anything else now.

any reason you use elf, and where do you get it from?

[tom]

I have found the best performance and wear resistance using ELF. For a synthetic/castor it is also very clean. Any good kart shop will be able to get it for you.

Morris oils are another good option, there chain lube has provided goos results also

I also went from Shell M to Elf 909 and have not looked back. Engine builder said the condition of my Motors were a lot better then when I was using Shell M and I have noticed a huge difference in the carbon deposits on the plug. Obviosuly a tad more expensive but the savings made on motor maintenance ect may be worth while.
