My apologies if this topic has been covered before. I just happened to notice a difference in the wording on a couple brass fuel caps I have on the wall. One says “Buy clean fuel and keep it clean”. We’re all familiar with that slogan as just about all Caterpillar diesel fuel caps say that.
The other one I have says “Use clean fuel and keep it clean”. I assume this cap is earlier but I don’t know that for certain.
Anyone know?
BP.
I'm no expert by any means but I seem to remember reading back when multiple fuels were used they could come from various different types of containers of questionable sources hence the use clean fuel . When diesel became more readily available and was bought instead of "obtained" where it could be found the buy clean fuel became standard.
I stand to be corrected by someone more knowledgeable or at least with a better memory.
That sure makes sense to me Gary.
The 2B casting number is earlier than the 3B number. Use clean fuel is the older
