hi everyone . well i just went and picked up my boat with my freshly rebuilt 140 johnson , they even installed the water temp gauge i ordered for it , i bought 6 cans of beer for that job . anyway when i was leaving the dealer he told me to use double oil for the first two tanks , and not go over half throttle. he also told me to use a good grade of oil and do not use wallys oil . he said they have had a few motors come in that were shot ,when he asked the customer what brand of oil they were using they said wally brand . any thoughts on this ?
