Hello Bezalel,

The 20 weight oil should work, it is just a bit thiner than 30 weight. You
may
have more oil coming out around the bearing with the 20 weight oil. I
would
think that the 40 weight that you've been using should work fine.

so far i've been using wd40 but today i went to look for the oil
recommended by record(motor oil grade w30) but couldnt find it after
looking for a while. all they had at the gas station was w20 grade for
diesel and reg gas motors. whats the difference between the two and can
i use w20 grade.
thanks

If you've been using WD40, you're lucky you still have bearings.

20W20 or 30W30 NON-Detergent oil is what people normally use for sintered
bearings.

Since almost all current motor oils are detergent oils, Universal Tractor
Fluid or 2-Cycle oils are often substituted.
