Need some help on the proper lubrication of my BP clone J head.
Most of the oil indicated on the manual are no longer in the market.
Maybe some of you guys have a better alternative on some of the oils.
The Vactra #2 by mobil is the only oil I know....the rest
...Gulfway #52, Kuo-Kuang R 68, Esso Febis K 53 ....
