There was that big push years ago with those engine treatments like Slick 50, I‘m sure you remember them. Have those gone away? Currently I see some oil treatment additives that you add to the crankcase and it‘s supposed to condition the oil (somehow?) but it‘s already multi weight, so why would you condition the oil?
Use only the additives recommended by the vehicle manufacturer in the owners manual in the fluids and capacities section.
I would only buy a heavy oil treatment like Lucas if I hear a tapping, hoping that it will quiet it down or at least give it a little protection.
i would,nt use that junk in my lawnmower. about all your oil today has additive in it when you buy it. i do use fuel injection cleaner in the tank once in awhile.
With the bike upright and both wheels on the ground, release the front QR, lightly squeeze the front brake lever and, while hold the brake lever, close the QR. Then test the wheel to see if it turns properly and if one of the brake pads is rubbing on the wheel. If it isn't turning the way it should or a brake pad is rubbing, take it to a bike shop and have them figure out the exact cause and fix it. Do not try to fix an out of true wheel yourself because it requires special and expensive tools to do it right.
