    Default Adding oil

    Ok I just want to know during a season how on average how many times do you have to add oil to your motor or motors? I had to add oil to both of mine and one took more then the other. It was my seventh time out and when I had to add.. I just curious if that is normal or do I have a potential problem in the future?

    Hard to say. From April 15th to June 10th I was doing three 25 mile trips a week, and one whole week of 25 mile trips and probably added 1/2 quart to the Honda 90. Just added 1/2 quart since then on Sat.

    I haven't had to add any extra oil yet. 130 hours on my motor. Changed oil at 10 hours, 23 hours (end of season), and 120 hours.

    Default Oil

    Good question and one that I'm going to Deweys today to discuss with them. I have an F115 with 80 hours on it and I end up having to add about 1/2 quart after every two trips (40 miles each). That seems excessive to me on a pratically new engine. The other issue is the color of the oil. Even right after I change it the first time I check it after a run it looks the color of coffee. I checked a buddies motor-same model etc. and his looked the same. Having run Hondas for years I never saw this-oil was never this dark. What is going on here? Is this normal for Yamahas??? The oil in my kicker-8HT Yamaha which I run alot trolling is as clear as when it was new....

    I have a Honda 15 HP kicker and use it a lot, but haven't had to add any oil.

    I add at least a gallon or so of oil for my Evinrude 250 everytime I fill up!

    Default This thread got me thinking

    so before heading to homer I checked my oil in my twin T-50's. I have put 86 hours on them at that time since april. They both were exactly at the fill line cold. I was surprised. The motors are a 03 and 04. I remember one time atleast where I added oil one season. Could have been from not getting filter quite full or something, who knows. I still say you can't beat a Yamaha.

    I have an 03 F115 Yamaha with +/- 240 hrs on it. I change the oil annually & have never had to add any oil to it.

    Default Oil

    Alaska Gray,

    Spoke with Tom at Deweys and here's what he told me. #1 Make sure the motor is horizontal when you check the oil. I had assumed that I should be checking it with the motor tilted completed down. But doing that results in the oil level appearing lower than it actually is. #2 "Full" should be 3/4 of the hatched area, NOT to the top of the hatched area. From our discussion it appears that I have been overfilling (based on not tilting the motor to horizontal and going to the top of the hatched area) and that causes (this is the part I'm unclear on) the oil to be blown out the exhaust. I followed his suggestions and went home and re-checked my oil level (that I thought was low) and it was at exactly 3/4 hatched area. So I'm going to run hard this weekend and then check it on Sunday night. He said he was fairly certain that this was the cause of my problem but if not bring it in and they will look it over. But we shouldn't have to be adding oil to four strokes...

    Hope this helps...

    I always check my oil with my motor as straigh up and down as possible. That was the head is level. Always checks good.
