My Dad has a simplicity broad moore with a 16 hp inteck engine. Most come with vanguards. I have a broodmoore myself witha 14 hp Vanguard and it has lots more hours and does not use a drop of oil. This 16 has about 230 hours and when we mow it takes a bout 1.5 hours and the oil is always low. I have to add to it every time. I cant find any leaks though it looks to leak just a little bit around the valve covers. Nothing severe though. It does not smoke so where is the oil going? This is frustrating to say the least. We are using 30 weight briggs oil and Im not sure who makes it but I dont even think that matters. Did we just get a bad one? Sometimes, engines will just use oil but will run forever. I have been a part of that in the past. It was with a 200 cid Ford straight six of all things. I just need advice and opinions. Thanks. This has me stumpted to say the least. Why does on engine use oil and other doesnt????
