That’s rough on the oil, and it could virtually shear (or split) the molecules in standard automotive oil, lessening lubricity. Yamalube 4M and 2M have special shear-stable polymers to fight this and provide outstanding lubrication continually.

Make use of the screwdriver to securely fasten the oil plug to circumvent h2o penetration and leaks in the course of use. It's also possible to Look at the reservoir keep track of and drain out previous oil in advance of filling it with lube.
