I've been using the Lucas upper cylinder lubricant for years on all my vehicles. I find it highly effective in reducing carbon on top of the pistons of my Harley Davidson. Due to the EPA regulations, oil mist from the engine breathers is routed back into the intake manifold, which adds to the carbon build-up on pistons. This Lucas product not only reduces carbon build-up but also lubricates the piston rings, fuel pump, injectors, valve guides, and helps cushion the valves against their seats. 1ml per one litre of fuel is all that's needed. Harley owners try this Lucas product before spending money on a breather bypass. It does work.

I've heard 505 CRF was EXCELLENT. What's your opinion ? Thanks

[@SimplifiedShopper-h6q]

505 CRF? Oh yeah, that stuff’s legit. It's a calcium sulfonate grease, so it handles crazy heat, water, and pressure like a champ. Perfect for off-road, marine, motorsports, you name it. People love it because it stays put and protects metal from corrosion, even in rough conditions. Downsides? It’s pricey and kinda hard to find, but honestly, it’s worth it if you're serious about pro-level protection. Solid choice!
